SBIR 95-1 SOLICITATION
AN ALTERNATIVE METHOD OF PRODUCING RHENIUM COMBUSTION CHAMBERS
There is a need to produce, on a repeatable basis, high quality
powder metallurgy rhenium combustion chambers that are less
expensive than the current units. The present method is to
produce such units from solid ingots using various advanced
machining methods that are both time consuming and expensive.
We propose to develop one NASA standard 25 pounder by adapting
metal spin-form techniques to meet the unique requirements and
difficulties to shape rhenium. If successful, this project will
greatly reduce the amount of material required to make such
combustion chambers and give greater flexibility in designing
larger units at a relatively low cost.
Potential Commercial Applications:
Rhenium combustion chambers have been produced and tested for
several years and have demonstrated their unique high
temperature properties. The aerospace industry requires a lower
cost alternative to the present method of making such chambers.
Pure rhenium is the material of choice, as it has excellent low
and high temperature mechanical properties, even in the
recrystallized condition. As rhenium chambers can operate at
very high temperatures, they can generate more thrust per unit
of fuel used. This leads to a longer life in orbit for the same
amount of fuel or more payload and less fuel for an unchanged
time in orbit. The cost savings for operating satellites, be it
for commercial or government applications, will be substantial.
Once developed, the technique for spin-forming of rhenium can be
applied to making other parts for high temperature applications
such as missile components, solar power units, other energy
generating units, and decontamination of hazardous waste.
