Additively Manufactured Liquid Injection Thrust Vector Control System

ParabilisSpace Technologies is pleased to propose the development of a Liquid Injection Thrust Vector Control (LITVC) system integrated into a regeneratively cooled, additively manufactured nozzle in response to solicitation S4.03, Spacecraft Technology for Sample Return Missions. The use of additive manufacturing and regenerative cooling prevents nozzle erosion near the injection ports, enables optimization of the nozzle surface for global system efficiency, and allows incorporation of high efficiency side force throttling techniques.The proposed innovation addresses the steering needs of sample return missionsthrough the use ofa high-performance LITVC system integrated into a regeneratively cooled, additively manufactured nozzle. The proposed system integrates extremely efficiently withParabilis' aft-injection center exhaust (ACE) architecture. The systemis particularly synergistic with JPL's hybrid rocket motor architecture proposed for Mars sample return, but it is beneficial for other missions as well.
