PROPOSAL NUMBER : 96-1 15.05-6100

PROJECT TITLE : Recombination Catalysts for Hypersonic Fuels

TECHNICAL ABSTRACT (LIMIT 200 WORDS)

Commercially-viable, reusable launch vehicles will likely use rocket-based combined cycle concepts, involving the use of atmospheric oxygen during a portion of the flight path. Such engine configurations will suffer significant performance losses as a result of incomplete chemical recombination of the exhaust nozzle product gas. The proposed research addresses this problem by proposing the use of relatively benign, inexpensive materials (additives) that would be added to the engine's fuel, react along with the fuel in the combustor, thereby generating oxides, hydrides and/or acids which accelerate the nozzle recombination chemistry. The proposed effort is innovative in that most of the catalytic materials to be investigated have not been examined (or suggested) heretofore, particularly in connection with RBCC propulsion systems. The proposed experimental techniques, which involve the use of a pulse facility to study nozzle recombination chemistry in the presence of catalytic additives, is likewise an innovative approach to the study of these important chemical processes. This work will have a significant impact on achieving the NASA goal of reducing the payload costs required for commercially-viable space access by minimizing propulsion system weight, while maximizing the energy extracted from the fuel.
POTENTIAL COMMERCIAL APPLICATIONS
Reduced payload costs resulting from the reduced engine weight and efficient use of the energy to be derived from the fuel will significantly reduce the technical and financial risks of applying RBCC engine technology to the civil and commercial marketplaces, thereby accelerating the time frame for large-scale applications by the commercial sector.
