Afterburners? Just a small thing...

[Dman979]

This should be a simple mod, but I can't figure it out myself.

Can you add a module to the Basic Jet Engine that allows it to go to afterburner?

I was thinking it needed a R.A.P.I.E.R-style switching mode, only with LF and Air.

It would have a vastly increased fuel consumption and would overheat quicker when on afterburner, but could produce more thrust and operate up to Mach 1.7.

Can you do this?

I'm not really good at that stuff, but you could write a ModuleManager plugin that modifies the stock jets to have a RAPIER/SABRE style switch mode, only with (like you said) vastly increased fuel consumption.

[Dman979]

I just wanted a new part, not a Module Manager.

[Dman979]

bump?

[Dinokin]

the closest thing that meets your requirements is this mod (not updated to 1.0 yet) > http://forum.kerbalspaceprogram.com/threads/70008-0-90-Advanced-Jet-Engine-v2-0-4-Apr-10

[Dman979]

But it requires FAR. And if I remember correctly, it reduces the overall thrust of the engines, not something I wanted.

[THREAD=9923]The Lazor System mod[/THREAD] has something like that (you'll need one of the lazor system main modules and yellow lazor on your ship) but it's currently broken. Also, it's maintained by Romfarer, who is one of the KSP devs and therefore busy, but it'll probably be updated eventually.

[Dman979]

Yeah, but that's out of date. Is there no way to add a few lines of code to a basic engine?

I would love to see that, along with a mode switch to ramjet for the advanced engine

[Dman979]

coolish!

[TheMoonRover]

Thinking about it that's a really good idea. I'd be interested as well. What's more I could probably do it. I've not actually written anything with ModuleManager before but I understand how KSP config files work, and presumably ModuleManager uses a similar format. But I've got exams coming up. If someone hasn't picked this up in two weeks, and there's still interest, message me and I'll give it a go.

[Dman979]

Will do, and good luck on your exams!

The advanced engine already is a ramjet. Read the description.

for the BJE, it's simple enough. Add the multimode, add a new mode, add some FX.

I am aware that it is a turboramjet, it just doesn't act like a real one, see the Pratt & Whitney J57.

What I'm asking for is a proper mode switch between turbofan and ramjet mode.

[Dman979]

And what I'm hoping is that someone will do that mode-thing for me. I tried it before and I had the same engine firing TWICE at one time.

I'll do some research but this shouldn't be too hard. Did you want it as a toggle on the existing part or has a whole new part? I can't really model a part.

[SpaceTiger]

I just had an idea how to do this with a plugin. Increasing thrust while increasing the heat that is being generated. But it doesn't seem like I'm able to decrease the isp for decreased efficiency.

Edit: Scratch that i managed to edit the isp curve so now the fuel usage can increase too.

Theoretically, it should be a momentary toggle, keyed to an action group, on the existing part.

I'd like a toggle on the current part.

[SpaceTiger]

Okay i got a working version just needs some polishing.

The action can be assigned to an action group too.

Tell me what you think about it

I shall try it as soon as I get to my KSP computer- which may be later today, tomorrow, or thursday.

+ Repped!

Dankeshen! Veil Gluck!
