Research Topics


Truax Engineering Inc. (TEI) is seeking SBIR Phase II funding to complete the configuration of a dual use, simple, low cost, 75,000 lb thrust, pressure fed, lattice injector, liquid rocket engine Model No. RCT-75K-097 R-1 and test it at Socorro, NM. The engine contains the following innovations aimed at lowering launch costs: A) A lattice injector design based on an entirely new and different injection principle never before attempted. (Design, fabrication, and test plan details are proprietary.) B) A combustion concept that carries the possibility for suppression of combustion instability, allows reliable ignition and re-ignition, minimizes afterburning, and has the potntial for high and predictable efficiency (C*) at any scale. Project objectives: The objectives of the Phase II work are to complete the 75 K engine pre-burner hydraulic proof testing, conduct water flow tests, and complete the planning and hot firing tests of the pre-burner at the New Mexico Tech, Energetic Materials Research Test Center (EMRTC), Rocket Test Stand (RTS), in Socorro, New Mexico. Additionally, Truax Engineering is proposing to continue investigation of dual use propulsion related technologies aimed at lowering space launch costs.
