About me



  1. do you think KSP2 will have ground effect? it's one of the things that causes planes to have more lift near the surface than in the air which means that if it gets added one could make vehicles that glide over the seas of planets for example
  2. This is a small mod which adds a detailed Airbus A330-900neo into the game. You will find detailed models and textures, custom sounds for the engines and landing gears, 3 liveries (White, Black, Airbus) as well as a modelled 3D cockpit and cabin. The plane is configured for stock, with flight characteristics based on a comparable stock-part aircraft. At a cruising speed of 220m/s at 3500-4500m altitude, a range of 2100km or fuel for 3h will be enough to cover all major routes on Kerbin. I've limited the crew capacity to 30 (+2 pilots) for performance reasons. Please note that the parts are not designed for a modular use in other crafts. Download from Spacedock I recommend you to install my Airplane Autopilot as well. Known issues All rights reserved.

  4. Like the stock Mk2 parts, but are round instead of streamlined. A lot of the time the stock Mk2 parts don’t really have enough capacity in the cargo bays or fit the aesthetic that I’m going for. They could also open up new opportunities for aircraft recreations. And for people who say that I could just use Mk3 parts, a lot of the time they are just way to big, hard to work with and difficult to get off the ground. These Mk2 parts IMO would make a nice alternative for when you don’t want to engineer a giant shuttle but still need some space. To make sure that they aren’t overpowered they would be heavier and less aerodynamic that the stock Mk2 parts. What do you think?
  5. My vision for this mod is to create stock alike believable parts to build passenger planes with. It is inspired by Airplane Plus, and will be made to supplement it as well as the stock parts. Here is an album with some concept art and work in progress screen shots: https://imgur.com/a/fAViy And here is an album showing up the semi finished parts: https://imgur.com/a/ljyIgIH Parts currently in the mod: Download at: https://github.com/neistridlar/Neist-Airliner-Parts/releases Tweakscale patch by @TMasterson5: https://www.dropbox.com/sh/u6cliq18972oo1g/AADtWdAcCjVC-oGoO1_Jycfaa?dl=0 I am pretty new to modding in general, so if you have advise or suggestions you would like to offer, please do so. I do believe, however, that I have many of the skills required. My plan is to use Fusion 360 along with Blender for modeling, Gimp and Inkscape for image and graphics editing. I do know a little C++, python and matlab, which might come in handy, though I have never programmed anything with more than a command line interface, so I expect to have a few things to learn if I want to get into that side of modding. Also I want to set this up so that it is easy for someone else to take over in the case that I should disappear (knowing my self I usually don't stay focused on one thing for more than 1-2 years at a time), so any suggestions as to how to accomplish this would be welcome. @kerbmario Is now making updates for Neist Airliner Parts: https://spacedock.info/mod/3034/NeistAir%20Reupdated This work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License http://creativecommons.org/licenses/by-nc-sa/4.0
  6. I'm looking for some VTOL aircraft topic on the spacecraft exchange and I couldn't find any so I decided to create my own. could the creations their post here please have a download link preferably stock but moded is fine. if there is already a forum for please link to it i would also be fine with VTOL tips
  7. Carrier Vessel eXpansion You can Download it here! Album: https://imgur.com/a/L3mph Images: Videos: What is CVX? CVX is a low parts mod that allows you to build a Nimitz class Aircraft Carrier. The mod currently contains 5 parts: 1 screw, 1 rudder, 1 hull, 1 radar tower, 1 bridge tower. The idea behind CVX is so players can explore Kerbin while carrying aircraft and not have to worry about having enough fuel, or... You just want an aircraft carrier without worry about tanking your cpu with parts count. What is Included? 5 parts: 1 rudder 1 screw 1 hull 1 radar tower 1 bridge tower Why only one carrier? More ships are on the way. Soon I'll be releasing a Wasp-class LHD, Essex-class CV (for recovering the Kapollo) and an Admiral Kuznetsov CV (for all you Krussians) in the first phase. The second phase is experimental carriers such as a submersible carrier and a helicarrier. Why are there no weapons or radar? There are already mods covering that, and a list of recommended mods are further down the page. Where can I get that F-14 craft? The F-14, made by GrandAdmiralJon, can be found here on KerbalX.

The release of KSP ver 1.2 fixes this so there is nor more the need for either use FAR or AirPark but both are excellent mods, try them anyway. The new current problem is the stock joint system, where even rigid attachment will allow parts to separate, KSP's attachment nodes weren't designed for such heavy masses. I recommend using the cheats for both inserting into the water and operation until Kerbal Joint Reinforcement is updated.

  8. I was doing some thinking about a context for a late WW2 aircraft design as I thought builds around this time period could be very fun and interesting. The theatre I came up with us an alternate timeline where the Luftwaffe wins the battle of Britain and successful occupies Great Britain. After this they successfully defeat Soviet forces and are then preparing for attacks on the United States. My vision would be that this war would be fought at Sea and in the Air. German forces from occupied Britain would fight for Iceland and Greenland in the North fighting against Canadian and some of the United States forces, whilst the United States Navy would try to hold Atlantic island chains in the South against German forces from Spain and North Africa. I imagine that Germany would have ramped up production of the Me262 whilst still producing late war Bf 109s and Fw 190s. Germany will have also completed their production models of Hitler's Amerikbomber which would threaten Cities like New York. My idea is that the USA would be forced to rush jets into production to counter the Me262. They would use jet engines sent from the British that they would reverse engineer to produce their own. Early jets were slow to enter production and were notoriously unreliable and had very short range so the US airforce and navy would need new piston aircraft capable of holding their own. Im curious if anyone else has any thoughts on where US aircraft design would have gone if they were forced to keep innovating and if the war was to be fought on this front. Also im going to be designing some aircraft with this theatre in mind using Realism Overhaul and Real Solar system if anyone wants to share some design ideas or specifications for new aircraft

  11. Similar to the "What is your favorite rocket" thread, just about your favorite aircraft. Mine are the Boeing 777 and 747, the Antonov AN-72 and AN-225, F-14 Tomcat, and, of course, the Sikorsky Skycrane ( I believe it is the S-64). I couldn't narrow it down to just one, you don't have to either (Just try and keep it under 10 aircraft)
  12. I've been playing the aircraft design Using mod installed in KSP (1.8.1 and now 1.12) for years, All of it is good, except for one fact that this mod generates lift in slow speed (taking off speed) obviously weaker than it should be in reality. I built aircraft according to the real-life examples, I always edit the mass and size in part.xml file and change all mods' setting to make sure the aircrft is close to real ones. This Fokker Dr.I in game is made to be 5.77m × 7.19m, Weights 550kg, Wing area is 20m^2. It's really close to the Wiki data, and I make the Mass-Lift-Centers-distance close enough for a fighter aircraft. However, the stall speed is tragically much higher than real-life-data's 72 km/h, I have to fly over 120km/h to make sure it doesn't need too much AOA to keep level flight. When it comes to other larger aircraft like B-29, the taking-off is so unrealistic that it feels like flying a Space Shuttle. I've been testing the different factors that might affect the Lift force, like the thickness of B9-procedural-Wing, or the length of Leading and Trailing edge, or the distance between deckedwings, And the result is, the only factors that determine lift, are Wing area (not matter how the wing is shaped) and Wing AoA in flight. So that means I can never use the real-life aircraft example's WingArea-to-TotalWeight Ratio to take off in the real-life speed, I have to fly much faster in higher AoA I've tried to edit part.xml to increase the "deflectionLiftCoeff " or any factor that looks like being about Lift or wingarea, but nothing works, the flight test data are the same. So, is there a secret setting button I don't know in FAR fuction that can increase the Lift generated in low speed ? Or is there any other ways to violently edit and increase Lift of B9ProcedralWing or other wingparts?

  14. I've recently been making a lot of aircraft in my new career game, and I'm looking for inspiration. I also think that simply seeing working planes improves new players ability to make aircraft, so... Post you aircraft here! They could be stock, modded, fast or slow, cargo planes or suborbital spaceplanes Just remember, no SSTOs as there is already a thread for that I'll start with my SR-71-K, heavily based off the SR-71 SR-71-K takeoff at dawn Climbing to altitude. Those ramjets produce lots of thrust Cruising at high speed, en route to the Northern Ice shelf
  15. 1:1 Scale Replicas Full stock, full scale, full power In a scaled-down universe filled with scaled-down Kerbals, it's easy to forget how big real planes are. I've been building planes to the same scale of their real counterparts, enabling more accurate replicas with functioning mechanisms like swing wings, moving lift engines, and the odd GAU-8 Avenger.

  16. http:// (CHALLNGE IS NOW CLSOED) Welcome everyone to another 'Quest for Hypersonic' challenge. This is a reboot of a challenge I did in September while already planning to try to make it bigger and better. Well now that challenge is pretty much dead and after some thought I decided to start a new one with some major changes. The original thread can be found HERE. Like in the previous challenge the goal is to build the fastest possible stock aircraft in either one of the two classes. Waverider, and Hermes. There are separate rules for both classes. (Details below.) If your design goes fast enough, you will receive a badge for either going faster than 3000 m/s, 3500 m/s or 4000 m/s. You will be able to put it in your signature. After you have submitted your entry, your result will be added to the top 5 leaderboard if you have beaten the record! So first, a bit of background on hypersonic travel. The term 'hypersonic' means anything traveling faster than Mach 5, or 5 times the speed of sound. Note: The speed of an aircraft is only counted as hypersonic if it is in the atmosphere and under 90 km. The first hypersonic aircraft was built by the US and was a two-stage completaly kerbal rocket that reached the speed of mach 6.7. Nothing but ash and dust remained of the rocket when it 'landed'. The first human to exceed the hypersonic barrier was Yuri Gagarin, (I am looking at you, Jebediah), and after that came Alan Shepard from the US. After that a series of developments led to the X-15 aircraft, which, to date is the fastest manned airplane capable of flight. CLASSES: Note: The rules apply only to the seperate classes WAVERIDER HERMES BADGES: These are the badges you get for building a craft that goes especially fast. You can either get one for flying faster than 3000 m/s, one for flying faster than 3500 m/s and one for flying faster than 4000 m/s http:// This is the badge you will receive if you build a craft capable of over 3000 m/s. http:// You will receive this badge if you build a craft capable of over 3500 m/s http:// Easily the hardest badge to get! This is the grand prize of this challenge! The 4000 m/s badge. WAVERIDER CLASS LEADERBOARD 1. @QuarkyGirl 5653M/S 2. @Pds314 5035M/S [email protected] troll children online. 4482M/S 4. @JorgeCS 4408M/S 5. @Vinhero100 4045M/S HERMES CLASS LEADERBOARD: 1. @QuarkyGirl:4806 M/S [email protected] 4067M/S [email protected]*MajorTom* 3107M/S 4. 5. HOW TO SUBMIT: To submit a craft, first take a pic of your craft and another picture of your record as proof. Then you can post it in this thread with the name of your craft and you record speed under 50 km. If you have passed the 3000 m/s barrier, then you will get a badge! GOOD LUCK AND HAVE FUN EVERYONE! AND REMEMBER, DON'T OBEY THE LAWS OF PHYSICS!
  17. Aircraft Mission Sharing/ Build Challenge I wanted to put forward the idea of a challenge where people can put forward ideas for and create different mission scenarios set in RealSolarSystem Mod such as a city fortified with tanks or a Bomb target somewhere in WW2 Germany and then let anyone who wants to download the save file then design their own Aircraft to complete the mission. I think this could create some really fun possibilities like building an A-10 like plane to take out a line of tanks or a WW2 Bomber with the range to reach Berlin from London to avoid BF109 interceptors and drop its bombs and return home. If anyone has any ideas or wants to take part let me know!
  18. I've been thinking about this for a while now and I'm wondering with the new stuff with the robotic parts and the new helicopter blades, why not get ones with tip jets on them like the fairey rotordyne, reason being with the helicopter motor (R7000 turboshaft engine) produces a lot of toque and i don't want to do a duel rotor design, for mass issues as well.
  19. So, I was attempting to build an F-8 Crusader in KSP today, and that got me thinking: Is there anyone out there who would be willing to make a mod for KSP that adds in the right parts to make a Vought F-8 Crusader? Then, I started thinking about what else a mod like that could include, other than the Crusader's Nose-section, engine-shroud/engine, tail fins, wings, and landing gear. One of my ideas was that with this mod adding F-8 Crusader parts, it could also add in a few other cockpits, wings/control surfaces, and engines. Among these could be different variations of the Crusader nose-section (such as a more futuristic and sleek one, a larger two-seat version, etc), and possibly entirely different plane cockpits. What do y'all think?
  20. Need I say more? More below if the answer is "yes." I bet lots of you are curious about how far your planes can go from their starting point when their tanks are full. However, I doubt all of you want to waste time just taking them out for test runs - one plane at a time. This thread is to finally know, once and for all, how to calculate your planes' range? In the spoiler below, you'll find SPH shots of a few of my aircraft - none of which are SSTOs. What bugs me is that the delta-V count for the engines don't really give a clue. If they are, then I obviously missed it. Could someone point that out, please? I also noticed that the Regional Jet Challenge had the range equation as the following. However, I don't know if it's accurate. Speed in this equation is the given cruising speed at the recommended altitude. Is there any way to calculate the range of my aircraft without needing to download any mods? Thank you.
  21. I realize this isn't a very exciting vehicle by the standards of this forum, but I'm very happy with it. Many of the aircraft I've designed have flown well but have been ugly, or have been sharp-looking but have not flown well. This one looks (to me at least) cool as all get-out, and flies very well indeed. Although I know that KSP has no military content at all, and no way (normally) to arm vehicles, I retired after spending more than 35 years in military service (part of that time in the US Air Force and part as a Department of Defense civilian). This design was inspired by both the US A-10 Thunderbolt II (affectionately nicknamed the Warthog) and by the Russian Sukhoi Su-25 (NATO reporting name Frogfoot), both of which are heavily-armed, slow-flying ground-attack aircraft. The KA-1 Stormbringer is a single-seat fixed-wing STOL aircraft powered by a single turbofan engine. It has a generous wing area for its size, giving it good lift and allowing it to operate from short runways. Its robust landing gear and sturdy construction allow it to operate from unimproved surfaces. It carries ten KAS-3 300-mm unguided (but gyrostabilized) air-to-surface rockets which it can fire in pairs. Whether loaded with rockets or after they've been fired, this aircraft handles magnificently, at least by my inexperienced standards. I can literally roll 90 degrees, pull back on the controls, and change my heading by 180 degrees with almost no effort and without pieces of my aircraft falling off. Or I can make the same heading change by performing an Immelmann or Split-S maneuver, at speed, with maximum control input, without my aircraft disintegrating. I have both of the expansion packs installed, and this designs makes extensive use of the TweakScale mod. I was unable to find a way to decouple the rockets when firing that didn't leave part of the decoupling mechanism on the rocket; if anyone has suggestions for this, I would love to hear them.
  22. Hey Y'all! Many past players have used all sorts of means to simulate airships in KSP, from jet engines to control surface spamming to landing gear glitches and even awesome mods like HooliganLabs. Since the game will calculate lift on an aerodynamic body regardless of how it's occluded (unless it's inside a fairing/cargo bay), we can build a helicopter that sure looks a whole heck of a lot like an airship using the new DLC parts. To this end, I've got another entry into the stock airship category: The Kindenburg utilizes two R7000 Turboshaft engines with 16 medium helicopter blades each, mounted to counter-rotate inside the wing-only section of the envelope. Outside the envelope along the sides, there are two electric rotors with duct blades which will provide our forward thrust. The lift engines are fed by liquid fuel and intake air, while the rotors and reaction wheels are run by the lift engine alternators along with a pair of fuel cells. The crew capacity is 10: 2 in the lander can, and 8 in the upside-down modules. Hanging the passenger modules upside-down was mainly for aesthetic reasons, as I found it to be the best and easiest way to make a good looking passenger module for an airship. I hear bats love to travel in this thing. Action Groups: AG1) Toggle lift engines power and fuel cells AG2) Toggle forward engines AG3) Toggle ladder Flying the thing can be a little tricky. The lift engines are mapped to the main throttle via RPM limit, and a throttle level of 1/2 corresponds to roughly neutral buoyancy. When taking off, it's best to do so with a little forward velocity for stability. Start out by hitting AG1 and releasing the breaks, then hit AG2 to start moving forward. Set your autopilot to prograde lock. Once you pick up speed, throttle up to ~1/2 thrust and you'll be off the ground. Don't try to gain altitude too quickly, otherwise you'll pitch up too far, flip out, and crash. Keep your nose close to the horizon and rely primarily on yaw for steering, bumping the throttle up and down from neutral buoyancy for pitch. Yaw works better for steering while at low speeds, but at higher speeds rolling is preferable. I've gotten it up to ~60 m/s at sea level, but you can probably push it beyond this. When landing, shut off the forward engines and deploy the gear. The massive drag of the fairings will slow you down, so drop the throttle slightly to descend and touchdown, then reapply the breaks.

  23. Level: Intermediate/Advanced: You need to be able to slap together a plane that flies reasonably well before attempting a VTOL. Background reading: Start with the fantastic Basic Aircraft Design tutorial in this very forum. Craft used to illustrate this tutorial: BAK Cyclone BAK Karmilla BAK Drakula BAK Zephyr BAK Bumblebee What's a VTOL aircraft? VTOL stands for "Vertical Take-Off and Landing." A VTOL aircraft as discussed here is a craft that's designed to fly aerodynamically, using lift produced by lifting surfaces, but take off and land vertically. That's what this guide is all about, so we're not talking about VTOL rockets that don't make use of wings to produce lift. We're also not discussing helicopters here, because stock kerbals have not invented the propeller, and stock propellers are a whole big topic of their own. So this guide is about atmospheric craft designed to fly by making use of lift generated by wings, which can take off and land vertically by use of downward-pointing jets or rockets. This guide also applies to STOL (Short Take-Off and Landing) aircraft which do their thing using downward-pointing jets or rockets, because they're pretty much the same thing. Their hoverjets just have a TWR of less than 1.0. Why VTOL? Because they're fun and educational and you can. Next question? No, seriously. Is there a point? There are a few missions for which a VTOL aircraft is ideal. Kerbin has some biomes that are difficult to reach any other way. The same applies to Laythe, although it has gentler topography. Finally, it is really difficult to land a HTOL atmospheric craft on Duna because of the thin air: you'll be going really fast and terrain is really bumpy, so there's a huge risk of ending up as a big ball of fire, whereas it's very hard to land a conventional rocket lander precisely, like when you're aiming for your surface base. On the other hand, atmospheric craft are superb for exploring it for the very same reason – you can scout for the perfect spot for your base, then land precisely there. A V/STOL atmospheric craft built for Duna can drop you on any dime, anywhere on the surface. But mostly, the answer is still "because they're fun and educational and you can." The BAK Cyclone hard at work on Duna. It's a flatbed freighter suitable for shuttling base modules to and from the surface. The cargo is near the centre of mass, but because it can shift, it's important to adjust the exact balance by tuning the power on the nose hoverjet... The basics At its core, a VTOL aircraft is a plain old aircraft, with downward-pointing jets that produce a TWR of > 1.0 with the vector centred on the craft's centre of mass, and some way of controlling its attitude when it is hovering, because control surfaces do nothing at an airspeed of zero. Getting all of this into one craft is a pretty intricate business, however. In particular, there's one constraint that needs special attention: centre of mass, and the invariance thereof, as you burn fuel. In other words, your fuel tanks need to be placed symmetrically around the centre of mass so it doesn't shift as the tanks dry, and you need to get your vertical thrust vector exactly aligned with said centre of mass. Regular HTOL aircraft can afford to be a bit sloppy with this because aerodynamic forces will effectively obliterate moderate shifts in CoM -- if your plane gets a bit more tail-happy as the tanks drain it's no problem, as long as your CoM stays ahead of your CoL. Mostly anyway. Not so with VTOLs: if the CoM shifts, you're not going to be able to land vertically anymore. Here's how you go about building a VTOL under these constraints. Build yourself a plane. However, don't put any fuel tanks on it yet, and empty any fuel-containing parts that you are using. Switch on the CoM and CoT overlays. Set the thrust limiter on your main engines to zero. Your CoT vector will disappear. Add enough downward-pointing jets to lift the plane, as symmetrically as you can around the CoM, in a minimum of two pods (fore and aft). (You can add more pods to the sides if your body plan permits it.) Adjust the thrust limiter on the fore (or aft) hoverjets until the thrust vector lines up with the CoM. Add fuel tanks symmetrically around the CoM. Add RCS jets to the bottom of the craft, at the nose, tail, and wingtips. Don't forget the fuel – Vernors need oxidant, the others need monoprop. (If you're building a very small craft, you can just use a reaction wheel instead. But that's less cool.) Set up your control scheme: one action group for toggling the hover jets, another action group for toggling the main jets, plus yet another one to toggle the hover jet bays, if you're using them (as you should). There, done. Simple, eh? Hoverjet design The first challenge you're likely to hit is choice of hoverjet. The second one is likely to be aerodynamics – if you just stick on some downward-pointing jets, you will find that they produce a lot of drag, which is going to be really inefficient. Your plane will be slow and have limited range, or you'll have to make it a lot bigger to brute-force your way around that limitation. The solution is to house the hoverjets in a cargo bay of some kind, with the doors opening downwards. That way you can tuck them away for normal flight, and expose them for hovering. There are lots of ways to make this work, but here are some designs I've used successfully: Juno in a Mk 1 utility bay. Stick it inside the utility bay, rotate it to point towards an opening, move it until it's completely inside. These are easy, pretty light, and you can add more of them – within reason – for more lifting power. Array of Junos in a Mk 2 cargo bay. This needs scaffolding: you need to put something in the cargo bay that lets you attach the Junos to it. A short Mk 2 bay will fit an array of 9 Junos, and a long Mk 2 bay will fit 18. That's a lot of lifting power – three Wheesleys' worth in the bigger bay! Also a lot of parts. I hope you have a fast computer. For rocket-powered hover, use Spark, Aerospike, or Vector (if you really need a lot of hover power). Terriers will also work on Duna. Sparks will fit in Mk 1 utility bays, the bigger ones will fit in the bigger cargo bays (Mk 2, 2.5m utility bay, Mk 3). Giving them air Air-breathing hoverjets need intakes. At this point you'll probably need to go back to the plane design you started with, because air intakes are dry mass and will shift the CoM as you add them. Hint: The engine pre-cooler and engine nacelle are fantastic air intakes, and they can be mounted in-line or combined with other elements. You don't have to use their fuel capacity – you might want to leave them dry if they're not symmetrical to the CoM. Hover control The main challenge for hover control is to keep the craft horizontal. If it starts tipping in one direction, you're really likely to flip over and crash dramatically, like a tree falling over. If additionally you can give it a controlled tilt and hold it there, then it'll start accelerating in that direction, like a helicopter. This can be most helpful when transitioning to or from level flight. Option 1: RCS RCS will get the job done nicely, and looks cool to boot. You will need more jets at the nose and tail than on the wingtips, as there will be more forces on pitch when transitioning to or from level flight. Your choice of RCS jet is the Place-Anywhere or the Vernor. You may need to add several on bigger craft. Option 2: Reaction wheels Reaction wheels will balance smaller craft just fine, but are probably insufficient for bigger ones. Managing centre of mass One of the most finicky problems with VTOL craft is managing centre of mass. In principle it's simple – just place your fuel symmetrically around the dry CoM, and centre your vertical thrust vector on it – but... how? Use wing-mounted engine pods on pylons. Engines are dry mass. Mount them on pylons on the wing, and it's easy to move them forward and back to fine-tune the CoM. Put fuel tanks outside your main stack. Wing-mounted tanks, wingtip tanks, drop tanks, and side-mounted tanks flush with the body all work, as long as they can be moved backwards and forwards relative to the dry CoM. If you don't mind a bit of clipping, you can even make the latter look pretty good by clipping them a bit in the body. It makes no functional difference, but if you consider it cheating, don't do it. Use a long, light tail section. Long tails are good for stability anyway. If you make a long, light tail, you can adjust the balance of the craft by making it slightly longer or shorter without adding a lot of weight or making big design changes. Body plans I've found a few body plans to be especially amenable to conversion to VTOL. They have in common that it's easy to tweak the balance by moving things around, rather than having to add or remove pieces. Twin-boom The twin-boom design is one of my favourites, largely because it looks cool. In a twin-boom design, you have one hoverjet at the nose, and one in each of the booms. Light craft have a single engine at the rear of the fuselage. Larger ones have additional wing-mounted pods. The BAK Karmilla. This one is balanced with reaction wheels. It uses six Mk 1 utility bay-mounted Junos for hovering. The BAK Drakula. A bigger twin-boom design using two arrays of 18 Junos on each boom and a single array of 9 on the nose. Twin-Pod A twin-pod design is similar to a twin-boom, except that it has a conventional tail extending from the fuselage. The hoverjets are housed in the big wing-mounted pods. The BAK Zephyr, a rocket-powered VTOL craft designed for conducting science missions on Duna. It is entirely powered by Terriers. The absurdly big wing and control surfaces make it highly economical for high-altitude supercruising. The BAK Cyclone, delivering a station module to Duna. Note the landing area markers. The Cyclone uses Aerospikes for propulsion. Rockets are much less efficient than air-breathers, so it needs to be much bigger than a Kerbin-bound craft performing the same mission! Control schemes and flight To fly a VTOL craft, you need to be able to perform the following actions, which must be bound to a an action group: Toggle the hover jets Toggle the forward jets Control attitude If you have full RCS control, you will additionally need control for that, and if your hoverjets are inside pods, you will want a control for toggling them too. Taking off The procedure for a vertical take-off is as follows: Hoverjet pods OPEN Forward jets OFF RCS ON SAS ON Hoverjets ON Throttle MAXIMUM When off the ground at a sufficient altitude to clear obstacles, main jets ON When at sufficient speed for aerodynamic flight, hoverjets OFF, pods CLOSED, gear UP The procedure for a short take-off is the same, except that forward jets and hoverjets will both be ON from the start. The craft will lift off once generated lift + hoverjet thrust overcome its mass. Landing To land a VTOL aircraft, approach the landing zone as you would with a regular HTOL craft, until on final approach. Then: Hoverjet pods OPEN Gear DOWN Throttle ZERO Main jets OFF Hoverjets ON Keep pitching up as you approach stall speed. When you're close to it, INCREASE THROTTLE until your rate of descent nears zero. Your airspeed will also fall. When your airspeed is low enough that aerodynamic control is getting sluggish, RCS ON, SAS ON. Control your vector primarily with pitch, and your descent rate with throttle. When your airspeed is near zero and you're above your landing spot, reduce throttle until you start descending. Touch down, CUT throttle, CUT engines, BRAKES ON. You've landed. ...and that's it really! I hope you've found this short tutorial useful. Have fun with your S/VTOL craft – and don't forget there are more ways to do them as well, including helicopter-like things that don't fly aerodynamically at all. My first VTOL craft was the Bumblebee, and it's still one of my favourites!
