Additively Manufactured Monolithic LOx/Methane Vortex RCS Thruster

Parabilis Space Technologies proposes to advance development of an additively manufactured liquid oxygen (LOx) and liquid methane Reaction Control System (RCS) thruster in response to solicitation H2.01, In-Space Chemical Propulsion. This RCS-class thruster will provide a simple, robust, and low-cost solution for vehicle attitude control on upcoming NASA projects. The thruster is additively manufactured in a single monolithic structure with minimal secondary processing. During Phase I, a prototype thruster was successfully designed, fabricated, and test fired multiple times. Phase II efforts include furthering the development of the thruster toward flight ready design, including expanding on additive manufacturing implementation and performing additional hotfire testing to evaluate a flight-like design and expand the operational envelope.
