  1. I have been experimenting with SSTOs in Je ne sais quoi (JNSQ) a bit lately. As it rescales the system by a factor of 2.7, it makes it a bit more challenging to build useful SSTOs there. Great fun. A combination of Rapiers, Wolfhounds and Nervs are the trick. Rapiers bring the craft to 1500 - 1550 m/s, where Wolfhounds and Nervs bring it to orbital velocities of 3800+ m/s. If build correctly, crafts have still enough fuel for a trip to Minmus and an ISRU for refueling. Here are some examples: Stiletto SSTA from 2019 2 Kerbals in command seats inside a service bay, ISRU in the front. 132t take off mass. https://kerbalx.com/Mephisto/JNSQ-02-Stiletto-SSTA-for-Je-ne-sais-quoi-Planet-pack Tanto SSTA Basically a redesign of the Stiletto with newer building techniques. 6 Rapiers, 3 Wolfhounds, 2 Nervs. 205t take off mass, 2 Kerbals in pods. https://kerbalx.com/Mephisto/JNSQ-X-4-Tanto-SSTO Tethys SSTA Up to 8 Kerbals, science bay, ISRU and plenty of other stuff. 284t take off mass, 10x Rapiers, 4x Wolfhounds, 4x Nervs. https://kerbalx.com/Mephisto/JNSQ-X-8-Tethys-SSTO Bahamuth Rescue Ranger Built for two rescue contracts, where one pod has to be brought back to the surface of Kerbin. Comes with a dragless rear docking port senior as well and a science bay. The rescued capsule has been attached with a small claw at the top: The 173t take off mass equals to 43,25t per Rapier engine. The rather low TWR at start means a take off besides the runway is necessary. https://kerbalx.com/Mephisto/JNSQ-X-11-Bahamuth-Rescue-Ranger And lastly a universal lander for JNSQ. Technically a SSTO, apart from Kerbin, Eve, Nara and the Gas Giants. Dolphin MK I Runabout As ejecting from a command seat through a fairing proved rather buggy for me, a hinge is used to bring the seat outside the fairing. Due to aerodynamic trickery, the whole body is shielded from drag, only wings and elevons produce drag (and lift). https://kerbalx.com/Mephisto/Dolphin-Mk-I-dragless-lander-for-JNSQ Have a good day, folks! - Mephisto-
  2. Shenaningans with drag and engine plates! Fairings and engine plates are both useful for drag shielding. Engines plates can also support many more nodes than intended! For reasons unknown, engine plates with a shroud do not only shield the attached parts at the back, but also the part at the front. We can use this, to shield the whole body of a craft from drag: This is a very small and basic lander for JNSQ. The whole body, the engines and the docking port at the back are shielded from drag. Only the engine plate itself produces a small amount of drag. As slowing down with a dragless body is impractical, wings and elevons provide lift and drag when needed for reentry and crossrange capabilities. A 1.25m fairing is the basis. An engine plate is added to the fairing. Shrouded engine plates have some unique features: they shield the parts at the back from drag AND they shield the part in front of it from drag as well for reasons unknown. This way, the fairing, the engines and the docking port are shielded from drag. To activate the shroud, a part needs to be added at the back. Here, a reaction wheel is added to activate the shroud and the magical shielding properties. In this state, the reaction wheel would still produce significant amount of frontal plate drag. To avoid this, it is later offset inside the fairing to be shielded as well. There is a trick to add more items to the engine plate: after we have already used the 4+1 nodes (the docking port is offset for a better view), the engine plate can set again to new nodes, where additional parts can be added, all shielded from drag when inside the shroud. Time for a check on the runway! All relevant parts are dragless. Only the elevons, the wings and the airbrake now produce drag (and lift).

Without drag? How?)
  3. You can do that, but parts will not be shielded against drag. So it is purely cosmetic, apart from the added lift in unwanted places whilst in atmosphere.
  4. Upgrades for my JNSQ-Fleet: JNSQ X-8 Tethys SSTO Just completed the first mission with my new SSTO in "Je ne sais quoi" to Minmus and the Mun. Has room for 8 Kerbals and can collect lots of science. Features: Command pod for Pilot and Engineer Passenger Seats for four Kerbals Science bay in starboard service bay Full ISRU complement (small ISRU, large mining drill, fuel cell arrays, RTG, ore tank) Frontal docking port junior via inflatable airlock at the bow Frontal parachute for parachute assisted landing (Duna, etc.) Breaking parachutes for quick deceleration after landing (Kerbin, Laythe, etc.) Sensors and scanners for ore detection Docking port senior at the stern. In space, an Engineer can put the cover on the upper part of the craft. Free service bay for future upgrades at the front. (Rover, micro lander, satellite, etc.) Special emphasis on high temperature and high impact tolerance for key parts: wherever possible, parts with high stress and temperature tolerance have been used to compensate for higher thermal loads in Je ne sais quoi mod.

  5. JNSQ X-4 Tanto SSTO Tanto on its way to orbit in Kerbal Space Programm with the Je ne sais quoi mod. JNSQ takes place in a system with 2.5x the size, meaning orbital velocities are higher and crafts have to be redesigned to cope with the higher demands in reaching orbit or reentering from orbit. The Tanto is equipped with 6x Rapier engines, 3x Wolfhound engines and 2x Nerv engines to be able to reach a low kerbin orbit with an orbital velocity of 3.800 m/s. It has enough fuel left to reach Kerbins second small moon, Minmus, and use its mining equipment there to replenish its fuel tanks for further voyages. It can handle the heat from low kerbin reentry as well. Link to KerbalX: https://kerbalx.com/Mephisto/JNSQ-X-4-Tanto-SSTO Mephisto (Flying like a leaf in the wind.)
  6. I might have a little craft for this: https://kerbalx.com/Mephisto/XS-07-Myrmidon-Liquid-Fuel-only-SSTO-to-Mun-and-Duna Took it from Kerbin to the Mun and Duna and back to Kerbin. To orbit! Fly me to the Mun... A flag! On the Mun! A nice day in the dessert. Hope they don't have sandworms on Duna...

  7. It has been quite a while. Welcome to 2021, everyone. Time for some updates! Hyperion Mk IV refit https://kerbalx.com/Mephisto/XR-26-Hyperion-Mk-IV-with-Stingray-Eve-Lander Refit of the venerable Hyperion Mk III from 2017 with modern tech. Contains seating for 22 Kerbals, ISRU, Mobile Lab, Mining Drill, lots of experiments. The engine layout is very powerful for a vessel of its size: it can even take of vertically. For short take offs, vectors in the back can provide additional thrust. Bobcats in frontal service bays help to bring the craft into the air. XS-11 Ifrit (Panther / Aerospike / Nerv Testbed) https://kerbalx.com/Mephisto/XS-11-Ifrit The Ifrit is a small craft, intended for carrying in a cargo bay. It serves two Kerbals as a landing and exploration craft. With full oxidiser, it has a range of 2,333 m/s dV with the aerospike. add some additional liquid fuel for the Nerv, and you can land on Tylo as well. With liquid fuel only, the Nerv engine has a range of 4,500 m/s dV. The onboard ISRU with the small mining drill allows refueling wherever ore concentration is 5% or higher. Onboard experiments can be stored on the drone core. The inflatable airlock allows docking with small docking ports. RCS thrusters support docking procedures. Kerbals can also replenish EVA fuel for their jetpacks when entering the inflatable airlock. Flags are replenished as well. To aid in horizontal take off, the craft has four airbrakes. Deploy the airbrakes for easy take off. On Kerbin, the Ifrit can reach orbit on its own: to save mass, only a 1.2t heavy panther engine provides airbreathing thrust. Use the Panther for take off and activate the wet mode to reach maximum velocity near sea level. When speed is maxed out, climb higher and add the aerospike and the Nerv. Orbit can be reached with about 500 m/s dV left. With this, you can dock with a mothership. XR-27 Sagitarius https://kerbalx.com/Mephisto/XR-27-Sagitarius Another iteration from the trusted line of long range explorers, Sagitarius brings 8 Kerbals with some level of comfort to almost any destination in the system, even Tylo. Equiped with plenty of science instruments and a mobile lab, onboard scientists will find plenty of new things to discover. The ISRU and Mining drill ensures the longevity of your explorations. 4 Rapiers, 2 Wolfhounds and 2 Nervs bring you to the stars. Max range on Nervs: 6,400 m/s dV. Max range on Wolfhounds: 2,700 m/s dV. Max range on Rapiers (rocket mode) and Wolfhounds combined: 2,390 m/s dV. Collapsible Rover in a box https://kerbalx.com/Mephisto/Collapsible-Rover-in-Box XR-29 Agathon - Orange tank to Tylo (in style) https://kerbalx.com/Mephisto/XR-29-Agathon-Mk-II-orange-tank-to-Tylo The primary mission of Agathon is to bring a 32t orange tank to the surface of Tylo. However, you can change the payload to any other you deem fit. Features Crew of 3 plus 16 Passengers Large Cargo Bay for 32t payload to Tylo Sturdy landing gears Mining Drills plus small ISRU for refueling on bodies and asteroids plenty of storage space with new parts -Mephisto- (Forward, unto dawn!)
  8. Nothing new for sure, but sometimes useful: Airbrakes instead of landing legs. Airbrakes are installed "inverted", as the hinge is at the back. The frontal part has to be below the center of mass to be able to lift. The upper airbrakes prevent the craft from toppling over. They weight only 50 kg each, as much as the LT-1 landing struts and half as much as the bigger LT-2 landing struts. Remove the lower airbrakes from the action group "braking", otherwise it lifts the craft up. Craft file: https://kerbalx.com/Mephisto/XS-11-Ifrit
  9. Seems I am kind in a retro mood. Another iteration of my trusted Grand Tour vessel, albeit this time without the Eve lander attached. It is really satisfiying, when all the panels, radiators, antennas and sensors deploy with a single click. As usual, with enough reach for Moho and enough thrust for a Tylo landing. No need for a seperate ressource scanning satellite, as all the scanners are onboard already. Enough Room for 8 Kerbals. XR-27 Sagitarius To the stars with Sagitarius! Another iteration from the trusted line of long range explorers, Sagitarius brings 8 Kerbals with some level of comfort to almost any destination in the system, even Tylo. Equiped with plenty of science instruments and a mobile lab, onboard scientists will find plenty of new things to discover.

  10. I had a different bug in 1.7.3., where the new ground objects from Breaking Ground where created based on tile size. As upscaled systems had much bigger tiles, lots of ground objects got created, making it unplayable for some time. I think it got fixed in the meantime. If I were you, I would ask in the "Add-on discussion", there might be a forum for your mods.
  11. I have an SSTO for JNSQ here. It is "only" 2.5x the stock system, but it might give you some insipirations: https://kerbalx.com/Mephisto/JNSQ-02-Stiletto-SSTA-for-Je-ne-sais-quoi-Planet-pack
  12. Back in 2017 I made a "work horse" SSTO, which should be able to do a number of jobs. The Hyperion Mk IV is a rework of the vessel with tech of 2020. Carries its own small Eve lander, some relay satellites, a small rover and fully capable SSTO with its own ISRU in the cargo bay as a small shuttle / lander / runabout. And because we like some redundancy, both Hyperion and the shuttle should able to land on Tylo and get back to orbit. Hyperion in the SPH. Note the small Stingray Eve Ascent Vehicle in the back. Hyperion in orbit with empty cargo bay. Sensors, solar panels and radiators deployed. Enough thrust for vertical take off with Rapiers and Vectors. The Rapier array is also quite overpowered for the craft. Rocket assisted short take off for rough terrain. Hyperion in SPH with loaded cargo bay. Ifrit SSTO in the frontal part. Smal Rover below it. Two Relay satellites in the middle. Between the tail fins of Hyperion is a small Eve Ascent vehicle wit a propeller and rocket stages.

  13. @xendelaar You mean the fuel tanks? FL-TX 900 and FL-TX 1800 have these ridges at the side. If you clip enough of them into a fairing of the same diameter, the ridges still look out. https://wiki.kerbalspaceprogram.com/wiki/FL-TX900_Fuel_Tank https://wiki.kerbalspaceprogram.com/wiki/FL-TX1800_Fuel_Tank 1.875m radial size is a good compromise between drag and part count for mid-sized vessels, in my opinion. If we only had a proper service bay with doors for this size in stock...
  14. Regarding rotors, service bays and drag Rotor inside service bay, service bay CLOSED: rotor is shielded from drag. Rotor cannot produce any thrust. Rotor inside service bay, service bay OPEN: rotor is exposed to aerodynamic forces. Rotor can produce thrust. It is possible to shield from drag, even when some small parts of the rotor are outside the closed fairing. Offsetting the blades is not needed. You can check this with aerodynamic forces displayed in action menues. It is best to the "Display aerodynamic forces in action menues" or something similar in ALT+F12 --> Physics to check, whether or not a part is exposed to aerodynmaic forces. If it is exposed, the numbers will change constantly. Even if the craft is standing still on the runway. Same goes for hiding other parts in fairings: you can check whether or not an engine or tank is shielded from aerodynamic forces with this. For many engines, you can find a sweet spot, where the part is shielded from drag, but can produce normal thrust without heating the fairing up. Here is a picture of a rotor assembly with open service bays. (Small motor, R25 Rotors, 1,25m service bays.) It can produce thrust with open service bay. When we transition to rocket flight, we power down the motors, lock it up and close the service bays to reduce drag. You can also see some fuel tanks sticking slightly out of the fairings. They are shielded form drag as well. Picture from this craft: https://kerbalx.com/Mephisto/XE-01-APEX-Mk-VI-Eve-SSTO
