The Air Force Research Laboratory (AFRL) Rocket Lab at Edwards Air Force Base, California has selected a Phase I Small Business Innovation Research (SBIR) proposal from P3 Technologies for award. The proposal is for an interpropellant shaft seal solution for advanced upper stage propulsion systems. The objective is to develop an innovative approach for combined thrust management and interpropellant seal systems for engine turbopumps.
P3 Technologies seal design was not possible prior to the availability of additive manufacturing. The seal provides improved leakage control, reduced flow rates, and enables configurations that can be packaged in reduced axial spacing for an overall reduction in turbopump size and weight. The seal has additional applications throughout the turbopump, as well as applications relevant to the commercial turbine engine, compressor, and pump markets
