Need help with a rocket motor ID

wrote: I've just received a few pics of a small rocket motor, from a friend of mine. It's about 2Kg and about 45cm long with a 10cm wide nozzle. It's a liquid fuel motor and doesn't look like it has any electrical connections. We're all guessing it could be some form of reaction nozzle for (maybe) a Gemini or Apollo capsule. Can I buy a vowel please ? Dave, Not much of a vowel but here's the stuff I got from a bud who's pretty heavy into rocketry (I am not). He didn't know what it was, specifically, but here's a bit more info you can add to the stew. One other note, Q is correct about the "SN63(4??), which is preceeded by what looks like a part #, which looks to me like it may be " ?07705" Cheers, jc "About all I can add to this discussion is that I'd agree it's probably designed for hypergols since there's no provision for ignition. Hypergols are binary propellants that use 2 liquids that spontaneously combust on contact. The only 2 I can name are furfuryl alcohol with hydrogen peroxide and the WW2 German bstoff and cstoff. That was the stuff used in the ME163 Comet rocket plane, I'm pretty sure one of the stoffs was hydrazine. That's some nasty stuff, it dissolves flesh. I've heard stories about accidental leaks and human soup. Yuck! Looking at the pictures a couple of other things strike me. Obviously there's no gimbal on the nozzle so it's not a manuvering jet. I'd guess either a seperation motor for a really big stage or possibly some kind of retro-fire thing. The other thing is the way the fluid lines wrap around the can looks like preheat to me. That either means a fuel that doesn't vaporize easily, like kerosene, or a cold soaked environment. That goes along with the idea that it's designed for vacuum. Where did the guy get it? Looks like government surplus to me. Hope my input helps." |
