KSP Realism Overhaul (RO) Engine Ignition

[Karol van Kermin]

Hey there!

I've been working on a reuseable rocket, powered by LO₂ & LH₂, recently. I figured out that the Space Shuttle Main Engines (SSME or RS-25) are very good and effective 1st stage engines, but I've got stuck with one issue: The SSME has only 1 Ignition available.

So I started looking for a mod, which gives you the ability to ignite engines a customizeable amount of times, by adding hypergolic or pyrophoric substances, such as Triethylaluminium (TEAL), which ignites spontaneusely in contact with O₂. TEAL is being used by SpaceX in their falcon 9 first stage, giving it the ability of igniting the merlin engines multiple times.

So I would like someone to make a mod (because I'm not a programmer), which gives you the ability of igniting your engines multiple times, by adding an external (or internal) ignitor, which is connected to a tank filled with a hypergolic or pyrophoric substance(s). It would be amazing, if someone could recreate what I've just written.

Thank you very much for your attention!

Hey, nice rocket lad. but about the ignitions, you can go into your realism overhaul folder, tske the config where the engine settings are. from there you can change the amount of ignitions. you could also pick another lighter engine and strap some moarr on the rocket.

Thats a good Idea but for me it kinda feels like cheating. But so far this is the only thing I can do.

thx for ur attention!

It's kinda cheating, indeed. but think of it like you just strapped on those extra ignition resources

Why? You have a spec for an engine that is at least reasonable, someone should be able to build it. The SSME was reusable after reconditioning, no reason that additional research couldn't turn it into a restartable engine. Use ModuleManager to add an additonal config to the SSME with extra ignitions and fuel. Up the mass a bit to represent the additional gear and requirements for a robust bell and turbopumps.

I mean, yeah, our RO pipe-dream for quite some time has been "procedural engines" but I'm not so sure it'll ever happen. This is the next best option. If it starts feeling cheaty just drop the isp a bit or up the mass or something.

This thread is probably better in addon disciussions, so now it's there.

Procedural rocket engines would be fugging dope. Just imagine adding every single detail on it, like piping, precombustion chambers, nozzle size etc. . JUST FUGGING IMAGINE THAT!

DrLicor :

Idk where to find the amount of ignitions. This is how my config looks like:

//New engine/cluster plugin patch
@PART[SSTU-SC-ENG-RS-25]:NEEDS[SSTU]:FOR[RealismOverhaul]
{
	%RSSROConfig = True	
	%engineType = SSME
	@mass = 3.526681
	@crashTolerance = 12
	%breakingForce = 250
	%breakingTorque = 250
	%maxTemp = 3588.15
	@MODULE[ModuleEngines*]
	{
		%minThrust = 1358.5
		%maxThrust = 2278.824
		%heatProduction = 100
		@PROPELLANT[LiquidFuel]
		{
			@name = LqdHydrogen
			@ratio = 0.728
		}
		@PROPELLANT[Oxidizer]
		{
			@name = LqdOxygen
			@ratio = 0.272
		}
		@atmosphereCurve
		{
			@key,0 = 0 453
			@key,1 = 1 363
		}
	}
}
+PART[SSTU-SC-ENG-RS-25]:NEEDS[SSTU]:FOR[RealismOverhaul]
{
	@name = SSTU-SC-ENG-RS-25x5
	@MODULE[SSTUModularEngineCluster]
	{
		@currentEngineLayoutName = Five-X
		!LAYOUT,*:HAS[~name[Five-X]]{}
		@LAYOUT[Five-X]
		{
			!MOUNT,*:HAS[~name[Mount-SLS]]{}
			@MOUNT[Mount-SLS]
			{
				%size = 8.4
				%canAdjustSize = false
			}
		}
	}
}
