Highest specific impulse is with the lowest molecular weight gas. As was pointed out, CO2 will not produce 2000 psi as the critical pressure is about 1100 psi at 95 F. Using a separate chamber just gives you another location to produce the ice. That chamber would quickly go to the freezing point...
No, this is not an existing application. We are doing a weight reduction program on a proposed design. We wish to go as high as possible in UTS without encountering problems such as stress cracking. D6AC was a former candidate but does not appear to be totally suitable. The application is in a...
I am looking for a material which is weldable and formable (spinning or deep draw) which is available in thin sheet (.025 to .031 inch) which is similar to maraging 350 in UTS. Any ideas out there? (also a source would be helpful)
