Novel Hybrid Propulsion System for Sample Return Missions

Parabilis Space Technologies is pleased to propose continued development of an innovative hybrid motor propulsion solution utilizing a novel bi-axial grain design in response to solicitation S4.03 Phase II, Spacecraft Technology for Sample Return Missions. Due to the innovative motor design, the proposed system is significantly shorter than a conventional hybrid motor system but maintains safety, reduced complexity, and storability advantages of hybrid motor systems. The system leverages additive manufacturing for the rocket nozzle and injector system in order to decrease both weight and part count. This innovation is an ideal propulsion technology for a variety of sample return missions from Mars or other bodies with significant gravity wells.
