Constant Mixture Expulsion Tank System (COMET)

ORBITEC proposes to develop a Constant Mixture Expulsion Tank System (COMET) to meet the Army's need for advanced gel bipropulsion tank systems the guarantee a constant volumetric Oxidizer-to-Fuel ratio. The benefits of the COMET result from the innovative mechanical linkage mechanisms developed by ORBITEC for maintaining constant volumetric propellant flow. The Phase I COMET development program will produce a series of detailed design studies of potential gel bipropulsion tank system configurations, including structural analysis, materials evaluation, testing of prototype mechanical linkage mechanisms, testing of prototype tank system configurations using water-based gel propellant simulants, the design of pressure relief systems to satisfy the Insensitive Munitions requirements, the preparation of three flight-like design alternatives for evaluation by the Army in Phase II, and detailed development, fabrication, and test plans for the Phase II effort.
