Software to Predict Distortion of Heat Treated Components

Not Available Miniature kinetic energy interceptors designed to destroy missiles by direct impact at high altitude operate using hot liquid or solid propellant combustion gases for attitude control and divert maneuvering. The combustion of solid propellant grains produces not only gaseous products but particulate as well. While filters are provided to remove large particles from the gas stream that might cause malfunction of the valve, small particles are carried along with the gas. Particles smaller than one micron do not degrade valve performance, but in the exhaust plume they degrade the seeker performance. Concerns associated with particle efflux include Prandtl-Meyer wraparound in front of the seeker and hot particle irradiance blinding or affecting the seeker for long-range missions, where the threat object is dim. In this project, Ultramet proposes to demonstrate the feasibility of an innovative filtration concept for <1-micron particles that will not cause deleterious pressure or clogging problems. Ultramet will team with Thiokol to ensure success and demonstrate hot-fire performance.
