Chemical propulsion research has not seen a quantum leap during the past sev-

eral decades in realizing a new engine concept with substantial improvement in

performance and reduction in size in spite of the various signicant advances and

research accomplishments. This is partly due to the fact that driving the com-

bustion process toward faster energy release rates, higher operational tempera-

tures and pressures, and utilization of exotic high-energy fuels will be dependent

upon parallel developments in high-temperature materials with adequate heat

management characteristics, control of combustion processes, and elimination of

pollutants and signature-carrying species. Propulsion Science and Technology

(S&T) calls for multidisciplinary programs with inputs from a wide spectrum of

basic and applied sciences.
