BURPG (Boston University) Lotus Dev 2 engine

Saw this last night while googling around. Liquid bi-propellent engine, website claims 233 sec ISP, 2500 lbf, and a >60 sec burn time. I've never heard of a "triplet" injector before.

Really cool stuff, i hope they're successful.

PS All of their engines are very impressive. "The Mk. IIB had the first successful implementation of liquid injection thrust vector control on a hybrid rocket motor" that is very cool!

Check out Rocket Propulsion Elements by Sutton if you're interested in bi props and injectors. Rocket motors with plumbing are sexy .

seems like I've heard around on the forum you're a machinist or have those skills? ..and in DFW. we need to get a beer

Yeah, for an engineer I have some decent machining skills. I do enjoy machining quite a bit for sure and used to do a fair amount of work on hybrids before I had kids. Who doesn't like injectors!? I literally have some designs framed on my office wall .
