Plasma Processes, LLC — Department of Defense SBIR Phase II: A novel lightweight thrust chamber has been developed in support of axial propulsion, gas

Description

A novel lightweight thrust chamber has been developed in support of axial propulsion, gas generators and divert and attitude control systems for missile defense interceptors. Characterization of metal lined carbon composites during Phase 2 will increase the technology readiness required for insertion into a MDA project such as NCADE, AKV, or MKV. Metal lined carbon-carbon composites offer an unique way to utilize the heritage of metal thrust chambers while significantly reducing weight via the use of carbon-carbon composite structures. The metal liner provides known compatibility with propellants, such as HAN, and a reliable, hermetic seal enabling the use of light weight carbon composites. The metal lined carbon composite chambers are 90% lighter than metallic chambers and weight equivalent to carbon silicon carbide composites. The weight of interceptors must be lowered to allow programs such as MKV, KEI, and NCADE to be successful. This SBIR generates the data and capability to reduce weight of critical propulsion components to 10% of existing technologies while maintaining proven reliability. Aerojet, the Phase II/III partner, will provide component design and testing at its facilities.
