Looking for more now - and the writing looks Aussie :-) Are bolts metric or SAE? SAE would probably mean US; metric would be inconclusive. The mounting bracket appears interesting- is it rusted, coated, or eroded in some way? My guess is that is not US military or NASA since an assembly this size would have a part label with part number. Unless of course it was made by the aliens at area 51... Hope you find the answer... |

Thanks Bill & Henry, It's sounding more interesting all the time. One obvious question--can you find out if those nuts are metric or SAE? --Bill Thompson |

NASA has recently announced (see http://science.nasa.gov/headlines/y2...metricmoon.htm that all manned operations on the moon will use metric measurements. This is probably NASA's way of telling the American public that we won't return to the moon after all, not if we have to go without our 3/8 inch socket wrenches. --Bill Thompson |

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." |
