[WIP]Somewhat detailed engine

[Sage]

Just a quick first mod that I did for myself, but I thought that someone might find it interesting so I decided to share.

It is just an engine, with a bulkhead of 1.25m but with a thrust intermediate between the skipper an the LV-30, and a better ISP in vac, but lower at sea level

INSTALL HOTROCKETS IF YOU WANT TO SEE ANY EFFECT, SINCE I REFERENCED NAZARI'S EXCELLENT WORK TO MAKE THEM

While it's not based on any particular engine, I've tried to replicate RL component and to design it by replicating piping that you see on the real stuff. Below there are the flow diagrams that I sketched (with elite paint skillz) to check if everything was modelled correctly:

you can see it's an open cycle engine, with boost pumps pushed by the high pressure fluids at the inlets and a stacked, direct, back to back turbopump design.

The fuel flow is used for active cooling, both in a descendent branch that is then fed back to the injection plate, while another part goes directly there while passing from the throat. A small quantity is used to lubricate and control the gimballing pistons and dumped as needed

Talking about pistons, the gimballing is animated correctly with flexible inlets as well:

The emissives are modelled somewhat accurately, by superimposing a map of the internal heat to a map of the cooling of a determinate part:

in game. the emissive are on the gas generator as well

Man that looks pretty sharp

Wow I love it! Needs RO config :3

[RobotsAndSpaceships]

Thank god, you actually did the heat emissive right.

[spacecookie]

Wow your work is stunning Are you planning to do more ?

[Mecripp]

No sound but look great.

[Sage]

Thanks everyone for the kind worlds

Wow I love it! Needs RO config :3

I play with a RO-like install in 64* kerbin so I will probably do one when the new RO will come out. Other than that if the RO crew wants to use this in the mod they're free to do it, but I don't know if it fits the bill of being a RL engine

Wow your work is stunning Are you planning to do more ?

Possibly yes, I've several other engines planned, but I've also several exams in my way. Anyway the next one should be an expander cycle engine for vacuum use with extensible shroud.

No sound but look great.

Strange, it should be referencing stock sounds, and it works on my machine. Can someone else confirm this bug?

And BTW, if someone wants the .blend or the unity project file, or even an explanation on how I got stuff working just ask!

God damn that looks impressive.

Hello Sage, do you have any public reference material from which you worked out all the components of that engine? It would go well in the Engineer's Handbook for Modders sticky

Nope, actually I used information I found in that incredible book about engine design you linked there, plus looking at photos of the real things that you can found searching on google and wikipedia

What's... what's the polygon count?

What's... what's the polygon count?

Only 5k tris, I think I've decimated it fairly well (more than most stock models, but I've played with mods that have pieces in this range. And in ksp part polys tend to add up only to relatively small numbers compared to most games, and the biggest performance hit is usually the ground of the planet you're on)

If so, the Bravo.
