Elephant Engine The Elephant Engine is effectively a 75% "Mammoth". It consists of three "Vectors" in a single 3.75m housing, for when a Mammoth is just overkill. As a side-bonus, mode switching in-flight will allow you to emit a plume of elephants, instead of fire. --------------------------------------------------------------------------------------------------------------- Download: SpaceDock -or- ksp.necrobones.com --------------------------------------------------------------------------------------------------------------- Creative Commons 4.0 Attribution-NonCommercial-ShareAlike CC BY-NC-SA --------------------------------------------------------------------------------------------------------------- Change Log: 0.2 (2015-05-06) - Initial Release. 0.1 (2015-05-06) - Internal Test.

Following my recent post on the pros and cons of Ion Engine and the overwhelming amount of response, I've noticed that a few of you fellow kerbonauts use ion engines mainly for your rovers. That's the background of this challenge. -- Mission -- Get to Minmus using a stock only lifter that has a rover powered by ion engines only (No delta V). Then you must land the rover/probe on the surface and drive around. While there be creative, maybe add some science parts for those of you in career mode? That is about it for the mission, if you attempt and/or complete this mission share your screenshots and your experiences on this thread! Thanks again, - Mr_Kerbal

After recently sending a probe to the Mun, I have came across some issues regarding the Ion Engine, but rather than list everything bad about it, I've decided to turn this into a conversation. What are your pros and cons of the IX-6315 "Dawn"? Please feel free to post your opinions on this topic below! - Mr_Kerbal

I'm wondering if it's possible to add two particle emitter effects to a single engine. I think it's possible, because I think at least the turboramjet effect with hot rockets worked that way. However this happened to me when I tried (see image below). What I did was I added to particle emitter objects in Unity to the empty object that is exported as a .mu file. This generates one .mu and two texture files. But KSP doesn't like it? Is there another way? The effect coming out of the exhaust is how it's actually supposed to look, but I don't know where the diagonal flame came from. Also, the engine can't be turned off or on, and the effect is always running...

I'm creating an engine switcher, and now I'm looking af switch the effects along with engine stats. Now I've run into en issue where the fx does not update properly from "OnLoad()" event. Basically what I do is Load settings from custom module Identify engine module to change Use ConfigNode to replace values regarding Fx in the engine Load the new values to the engine. I only have one update function, which is called by the OnLoad() event as well as by my switch button in the right click menu. However, when loading (or starting) a flight scene, the animation is just running with the animation from the original part. The issue seems to be triggered when the fx intended is different from the original one.... The behavior is not affected by deactivating the engine... (full code can be accessed here) I guess there is some trick to get the fx changes to take effect, but I just can't figure out what it is. Does anybody out there know what is needed?

Nuclear Aircraft Engines Download Thermonuclear Turbines (for KSP 1.1.2) on SpaceDock! A new hot way to get into orbit! This is a small engine mod that adds nuclear turbine aircraft engines based off of this concept, Aircraft Nuclear Propulsion, Project Pluto and the similar Soviet program Tupolev Tu-95LAL, also with a little influence from the Choujikuu Yousai Macross anime series and sequels to give two of the engines space capability. The concept behind the engine is that thermal energy is transferred through a heat exchanger into the "can" (combustion section of a turbine) instead of using combustion to rapidly heat up gasses to turn the turbine and provide thrust. Features for ver 1.1.0 (KSP 1.3.1) Update: COMING SOON! MOAR! Engines: 4x Nerv, 2x Nerv, Fusion Plasma Impulse, M.A.S.A.M.U.N.E., Back Draft, Fire Storm, and Fire Whirl. Two radial mount VTOL engines, Nuclear Vacuum and M.A.S.A.M.U.N.E. style. Bussard style Fuel Scoops, Size 1 and Size 2 varients. Radial space plane fuel scoops, Bussard and atmospheric. More fuel tanks to support the engines. Four Fuel-O-Tron converters, Size 1, 2, & 3, and Mk 2. Example Crafts Custom Sounds Custom FX Current Issues: A few minor bugs I'm working on fixing, otherwise the engines work as it says on the tin. CHANGE LOG 1.0.12: 1.1.2 Compatible, Updated Module Manager Dependency 1.0.11: 1.1 release, updated packaged *.dll plugins (Module Manager, FireSpitter, Smoke Screen). Minor changes to the Example Craft. 1.0.1P: Fixed location of FX folder, Fixed some issues with Example Craft. 1.0.0P: Release for 1.1 pre.

I seem to be haveing some problems getting a VTOL running. Not because of balance issues, but one of the two engines always fails! I've rebuilt the plane several times, and each time, one of the VTOL engines on either wings just flames out for appearantly no reason. I'm not really familiar with the game's air flow logic, but it seems like it shouldn't be happening. The engine on the left flames out during spool-up, but the one one the right runs fine Plane side profile Plane top profile

This mod have moved to the released section of the forums Ever wished the stock MultiModeEngine could handle more than 2 modes for engines? GTI Multi Mode Engine does exactly this. The purpose is to introduce an alternative way to switch engine configuration (propellants and other properties). The key source of inspiration comes from InterstellarFuelSwitch by FreeThinker. I find that supplementing it by versatile engines is a great asset. I've added simple intake switching, so intake atm is more attractive, and the days of adding two intake modules to an intake can be over. Pictures Features: GTI MultiModeEngine: Multiengine switch (conceptually what InterstellarFuelSwitch does, just for engines) Select which engine ID to affect Availability (Flight, Editor) Propellants, Ratios, IgnoreForISP, DrawGauge Custom naming of Engine configuration Set Engine Type [LiquidFuel, Nuclear, SolidBooster, Turbine, MonoProp, ScramJet, Electric, Generic, Piston] Thrust Heat production Curves: atmosphereCurve, velCurve, atmCurve Technology needed can be defined (currently not working) Engine Exhaust Effect switches when engine is switched UI Override of individual engine Activate, Shutdown and KSPFields in the right click menu UI_CHOOSEOPTION for switching between engine configurations Next/Previous Action Possibility of 8 Individual actions for engine, i.e. first 8 configurations can be accessed directly through actions (custom button defined in VAB or through AGX) Multi Mode Intakes: Switch intake resources on the fly current resource will be reset to zero (intended) Other setting will remain unchanged for now. Only one intake should be present in any one part. Only the first one is changed. How: (There are no parts added with GTI Utilities, this is intended for use in other mods) List of Atmosphere Curve in the Kerbol system. Very nice when deciding on form of the curves for the engines.

Nerva HT Engine v1.0 Late-game 2.5m Nuclear Engine. I was originally asked to model an engine for this mod, but unfortunately the mod was halted and I never got to finish it. I went back to my original draft and started over to release the engine model on my own and use it to learn how to mod KSP from Unity.

I'm working on a mod for engines. One basic function is supposed to be switching the propellant on an engine, like fuelswitch does for fueltanks. It is supposed to function as an alternative to the engine switch like on rapiers. I aim at integrating against tech level, and maybe inflight upgrading by EVA or something. Now, my current issue is, I cannot get the propellant switch to work. I can change the name of the propellant, but that does not change the propellant. A copy of the full C# module in it's current state can be obtained here. I think I need to change the ".id" of the propellant to get the game to recognise the change. If this is what I need to do, then I do not know how to obtain the resource ID's other than through the error logs in KSP. I've tried "PartResourceLibrary.GetDefinition(string)" but I get an error I simply cannot figure out how to fix. --> "An object reference is required for the non-static field, method, or property 'PartResourceLibrary.GetDefinition(string)'." I reality I would really like to be able to delete the old propellants and replace them by new ones. Can anyone help?

I've been working on an improved nuclear engine for the past few hours (don't tell my english teacher) and it's almost done. Just one problem, I can't get all three modes to work. It just goes from liquid fuel to intake air, skipping oxidizer. Help is greatly appreciated.

For some reason can't get engine light mod working with real fuels? I've tried messing about with the mm configs but no joy. Please help!!!

I have a multi-mode engine where the animation works in one mode, but stops working in the second mode. How do I make the animation work in both modes?

I made a mod for a super-powerful engine, using seamlessly integrated North Pole UFO tech. (some anti-gravity stuff to propel the LfO out faster. --==Hyperengine==-- This is the first of its kind in the Hyperparts Co. series of mods. I can also add your mods, if they have OP parts, and Hyperparts Co. as the manufacturer. You will be given 90% credit (because I inspired you ).

Hello all, I'm still a novice here, so if what im asking for already exists, please point me the right way I'm looking for a set of large in-shell propeller engines, like those on a Sci-f- helicopter or the Marvel Helicarriers. something that would optimally be usable with twaekscale, and surface mountable (so that it could bat attached to the wing). I've been experimenting with using the high bypass fan from the MKIV pack as a graphic for a 2 part engine. the engine its self is an intake with reversible thrust (it can act as suction and intake, or propulsion). Ideally you would toggle the modes in the SPH, or have 2 separate parts functioning in tandem. the suction engine function would have reverse thrust of low power and high intake, the propulsion side would have high output but no intake. also, true to realism, neither would have any gimbal.also might opt for a resource that isn't intake air as not to allow use of alternate air intakes, powered by electricity preferably. im kinda bad at the codeing, so if someone could provide some scrips for this (of just a part; i don't wanna be stealing someone else's graphics) that would be awesome. (the idea is something like this http://i3.photobucket.com/albums/y90/hybriddiesel/maglevrotor.jpg )

It's kind of a pain to have to set thrust to zero so you can manually adjust each individual engines thrust limiter. I was thinking it might be nice to have an option that would allow you to incrementally increase or decrease each engines thrust limiter via an action group.

We have several RD-107/108 engines in various mod packs right now but they all suffer from lack of detail or integrated fairings. I was wondering if anyone was up to the challenge of producing a set of BobCat-esque (think Soviet Engine Pack) models for the RD-107 and RD-108 for use with Realism Overhaul? Perhaps to integrate into FASA or another "replica" mod? Something like this (RD-107): And this (RD-108) The main nozzles don't gimbal but the little side engines (S1.53800) do gimbal. Obviously some detail can and should be omitted for performance, but models like this would be great additions to the Realism Overhaul game as the "naked" R-7 engine selection could use some love. Thanks for your consideration.

Hello all! Over the past year I've been part of an internship (sort of) that's hosted by my high school, in which we work with volunteers from Aerojet/Rocketdyne to develop a liquid fueled rocket that we're planning on launching as the IREC (InterCollegiate Engineering Competition) sponsored by ESRA in Utah this June. Last year we had our first engine test, but due to fuel/oxidizer ratio issues and combustion blowout (the propellent burned outside the nozzle), we only got fifteen of the expected hundred pounds of thrust. Discouraged and frustrated, we left the project over the summer and continued in October. Finally, this Saturday, after weeks of analysis, engineering, and assembling, we were ready for our second engine test. Here's the highlights: We replaced the solenoid valves with servo valves so they could open slowly to allow combustion to build up, and adjusted the propellent mixture, to glorious results! Unfortunately the avionics team had some trouble with the load cell data acquisition system, so we don't have thrust data for the engine as of now. Therefore we'll have another test in a few weeks, and hopefully we'll get the engine starting more reliably as well. Playing KSP, you don't always think about all the pieces that go into every component of a rocket, but this process has undeniably filled me with respect for NASA, SpaceX, Blue Origin, Aerojet, and everyone who works on these systems. Keep up the incredible work! -RixKillian

A mod that adds many turbofan engines based on real-life counterparts (i.e. Trent family, CFM56/CFM-LEAP, GE90) would be nice, as this allows construction of many passenger/cargo planes based off of real-life commercial and cargo jets. The Goliath turbofan in 1.0.5 is only suited for medium-heavy planes like the Stearwing A300. Having a mod like this would allow customization of planes that can carry a certain amount of cargo.

As the title says: we have listed values for vacuum and ASL thrust, but how is the Isp/thrust interpolated from there (or extrapolated for higher atmospheric pressures)?

First post here; joined to discuss rocket designs, SSTO, and reusability. Air-augmented rockets (also known as ejector jets or ducted rockets) are a sort of cross between turbofan jet engines, ramjets, and pure rockets. Ramjets depend on a ram-compressed flow of atmospheric air for combustion, making them useless for launch and for orbital insertion. An air-augmented rocket uses a stream of atmospheric air only as added reaction mass, greatly increasing specific impulse in a fashion similar to a turbofan bypass. They can afford to use fuels with greater energy density, because so much of the reaction mass is external. Best of all, because their core is more or less an ordinary rocket, they have no problem functioning from a standstill or in a vacuum. (For reference, there was a prior forum post on air-augmented rockets here, though it didn't go into many details.) The most efficient turbofan engines are built with extremely high bypass ratios, exceeding 10 kg of bypass air for every 1 kg of airflow through the central turbojet. Of course, the primary difference between a turbofan and an air-augmented rocket is that the power is delivered to the air mechanically in the former case, but thermally in the latter case. Air-augmented rockets have not historically been very successful. In most cases, adding a shroud around the outside of an existing rocket was a large weight cost in exchange for only a modest increase in thrust specific fuel consumption, and because they weren't optimized for using the air as reaction mass, most of the added thrust was the result of secondary combustion between the fuel-rich rocket exhaust and the atmospheric air, making them essentially very inefficient ramjets. If, however, an air-augmented rocket engine were designed in an inside-out configuration with a central bypass rather than an external bypass, you'd end up with a much simpler, more compact, potentially much more efficient design: Such a design could allow a really, really high bypass ratio, causing thrust specific fuel consumption to drop ridiculously low. The combination of really high thrust and really high specific impulse is pretty nice. I wonder whether this could be made large enough that the thrust augmentation more than overcomes additional drag. Thoughts?

I'm sure this has been asked umphteen times before, but my part is, after being exported from Unity and getting a hastily written .cfg file, not appearing in the VAB part list at all. I've given up on trying to animate the gimbal for now to reduce the chance of hierarchy errors and stripped everything down to its bare necessities, to no avail. Here's a screenshot from Unity And the config, partially copied from a stock engine. Can a kind soul help me spot the error? Possible anomaly: when imported into Unity, the model was solid pink and I needed to manually assign a material to it.

Hi everyone, Looking for a mod that features wide (but not long) engines? Also, is there any good mod for pivoting wings and engines? Thanks, Chris (Heretic391)

Maybe someone already suggested, but I didn't find in quick search trough links/threads. Can engines have toggable fuel drain switch ? For example, jet engines have this: That allows balanced drain from all fuel tanks. But it is not always desireable option. Sometimes I might want for jets to drain fuel only from first stage. Jets are efficient on thick atmosphere, so could bring rocket to above 10km and drop that stage. Only after that rocket engines are fired when there is less aerodynamic forces to destroy craft. Another example is oposite, I want to create spaceplane based on nuclear engine that drains fuel unbalanced from first fuel tank that is attached to, but for space plane eaqual balanced fuel drain is preferable to maintain center of thrust and center of mass aligned.

https://en.m.wikipedia.org/wiki/New_Shepard#Propulsion_module https://en.m.wikipedia.org/wiki/Bristol_Siddeley_Gamma In the late 1950s to 1960s, British companies experimented with RP-1/H2O2 engines. Burning an 86 Percent mixture of Hydrogen Peroxide and water onto RP-1, (the peroxide which was passed through a catalyst to first decompose it) the rocket engines managed to pull a 265s ISP, and lead to the Gamma Family of rocket engines, which powered the Black Knight and Black Arrow Launch Vehicles. Since RP-1/H2O2 is hypergolic, no ignition source was required, and the engines were very simple and reliable- there were no engine failures through the history of the Gamma family of engines. Additionally, H2O2 is non-toxic- thus the Gamma engines had most of the advantages of a Hypergolic engine without the toxic propellants and exhaust. This kind of make you wonder why this propellant combination was abandoned for the most part. Though there were revivals by companies like Beal Aerospace and now Blue Origin for use on the BE-2 engine, H2O2/RP-1 has remained largely unused. Yes, rocket engine development is expensive, and it is less efficient than cryogenic, or even the Titan IV's hypergolic propellants (302 s ISP for Titan IV, and 266s ISP for a Gamma 8 RP-1/Peroxide engine) but it would still make for a good throttlable cheap SRB alternative. Also, the good reliability records and experience with the Gamma engines made me wonder why they decided against a similar engine's use on say, the Ariane 1- or why Blue Origin decided against using it for New Shepard, and instead using H2LOX.
