[0.22] BT Engine Pack v1.3

[rifter]

Okay so been looking at this engine and while I do like it quite a bit. The problem is that at nearly all velocities the stock Turbo jets are higher thrust and they peak out at 2400m/s vs. the scramjet at 2500. There's very little advantage to carrying this with you. I would suggest upping max Thrust to 90-ish and bumping mass to maybe 3 or 4 which will make the TWR closer to the real thing (but still balanced for KSP) Also make the effective velocity range a bit wider maybe 1250m/s to 2800m/s. Those are my recommendations pick and choose.

I would argue it works fine as-is, since it fills a niche that is only really exists because of mods like TV Aerospace or FAR. The stock turbojet is meant to fill the same role as a scramjet all by itself, in absence of any real stock alternative.

Okay, I decided that since Hey, I have a realistic engine that seems massively underpowered to the point I had to tune it up, why not add a realistic engine that seems massively overpowered to the point I have to tune it down.

With that in mind I humbly present the Merlin 1-D Rocket Engine. It has about half the thrust of the real thing, but the ISP is the same.

Once again forgive my poor modeling and texturing.

[Chase]

I was wondering if anyone had any suggestions for additional engines or other parts I could make. I don't mind doing some more modeling and texturing for this.

Maybe more real rocket engines like your Merlin 1-D? Engines like the RS-80, RD-0146, RD-180, RD-170, NK-33, LE-7, or the Raptor. I love your stock-alike Merlin 1-D by the way.

[Chirality]

I looked through the cfg file and saw that the description has it's, instead of its. Sorry if I'm a grammar Nazi.

[iVG]

Can we get some 1:1 real life engines that we can use with the rescaled solar system mod please?

[Guest]

i second this, a RO/RSS fixed scramjet and merlin (is it dual use. like air breathing and rocket mode?) would go along way towards making realistic suborbital planes and SSTO's in RO fixed RSS (esp for the RPL tech tree)

[NathanKell]

Uh, the Merlin 1D is the rocket engine used by SpaceX. It's not combined cycle at all. I think you're thinking of the SABRE. An AJE version of the scramjet would be great though!

[mdapol]

The B9 pack has working Sabre engines which are probably already tweaked somewhere for RSS.

Edit: Also Laztek already has a Falcon and Dragon replica that has been tweaked (elsewhere) for RSS.

I changed the velocity curve to work better with RSS, so I can achieve 11 Mach @ 60km, using ultra light concorde like design.

Still not very useful on spaceplanes, as too low Lift/Weight ratio on super thin atmosphere. But it is still cool to experiment and close enough to realism.

Changed the last 2 values in the part.cfg

velocityCurve

{

key = 0 0.2 0 0

key = 1350 0.3 0 0

key = 1500 0.8 0 0

key = 1700 1 0 0

key = 4000 0.3 0 0

key = 7000 0 0 0

}

Hey guys, just to clarify, does this mod work ok with 23.5?

Also, how realistic is it? I don't need it to be super realistic I just don't want it to be laughable, like Hooligan labs airships when by default they are set to give 40 times as much lift as they actually would for their volume

[Arron Rift]

Wow, does anyone use this mod anymore? Would have thought someone somewhere would say SOMETHING by now

[NathanKell]

No air-breathing engine in KSP (without AJE) is *ever* going to be realistic, because the thrust won't vary with air density. If you want a realistic scramjet...well, it's classified how it works, so nobody outside the aerospace companies / DoD actually knows. But your best bet for now might be to set crazy-high temperature limits for an AJE ramjet.

It's a parts pack. There's no plugin involved save stock plugins. If it were a very old parts pack (basically before the PART{} configuration or before PartModule) then it might require special effort to get working, but it's not.

Simply put, it's just not old enough to worry about. It'll work.

Yup. I'm using it right now and it works beautifully.

This would be very useful- please update!!

[senoiurkabls]

Yeah if somebody could update the scramjet that would be great.

[Nothalogh]

You'd probably have better luck with the Instell scramjets by 8bitsblu
