 Orion Propulsion successfully completed the first series of hot-fire tests of a new 100 lbf oxygen-methane thruster module. This effort is in conjunction with a Phase 2 NASA Small Business Innovative Research (SBIR) grant and a space act partnership under NASA’s new Innovative Partnerships Program (IPP). For both of these efforts, Orion is currently developing a 100 lbf oxygen-methane thruster that can operate with both gaseous and liquid propellants.
The purpose of the thruster module project is to design, fabricate, and demonstrate the use of composite cryogenic tanks integrated into a propulsion system that is representative of future mission requirements, such as NASA's Orion Crew Exploration Vehicle, Lunar Lander, and long duration space missions. The system utilizes NASA-provided composite tanks, which have undergone extensive cryogenic testing with multiple cryogenic fluids, including liquid oxygen, liquid nitrogen and liquid helium.
NASA Marshall Space Flight Center’s composite tank expert Tom DeLay said, “ This methane thruster development was a fantastic way to demonstrate system level performance of high performance composite tanks and is a step toward scaling up to a full-size vessel.”
The next step on the thruster module effort is to perform a series of extended storage tests on the cryogenic tanks. Orion and NASA will continue hot-fire testing of the module with gaseous and cryogenic propellants. The system will be operated under the conditions of a pressurized propellant system and under the conditions of saturated propellants operating in a blow-down mode.
"Green and in-situ propellant missions are becoming more apparent as industry's needs and mission objectives are changing, and this thruster module is ideally suited for those missions." says Tim Pickens. |
