Interstellar Technologies

I think this team deserves it's own thread.

Youtube playlist of their recent tests

12 Kn engine fire, slightly on the melty side. Stated to be an upcoming sounding rocket engine



Vertical fire of the same, testing TVC systems



Older flight of a VTVL testbed

I'm glad someone made a thread about these guys, I was wondering about that rocket nozzle. I've never heard of a nozzle where the entire thing glows white-hot, top to bottom -- what's the deal with it, like what kind of engine bell is that? Is it ablative?

Anyway I love what these guys are doing on a shoestring budget. I'd love to see them get to the level where Masten is.

It's called radiatively cooled nozzle. merlin 1 Vacuum has it. And I think the RD-58MF is supposed to have a composite one. You basically use a material that can tolerate the heat and put some serious thermal barrier upstream.

Per their site, most of their engines are ablative, but it's quite common for these things to look a lot whiter in photos and video than they would in person.

Seems as per latest tests, they are experimenting with liquid cooling jackets just now.
