Research Topics


Truax Engineering Inc. (TEI) is seeking SBIR Phase I funding to complete the initial configuration of a simple, low cost, 75,000 lb thrust, pressure fed, lattice injector, liquid rocket engine Model No. RCT-75K-097 R-1. The engine contains the following innovations aimed at lowering launch costs:A) A lattice injector design based on entirely new and different injection principle never attempted before. (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 I work are to complete the 75k engine pre-burner hydraulic proof testing, conduct water flow tests, and complete the planning for hot firing of the pre-burner at the New Mexico Tech, Energetic Materials Research Test Center (EMRTC), Rocket Test Stand (RTS), in Socorro, New Mexico.
