Abstract

Theoretical rocket performance calculations were carried out for systems using various silicon hydrides up to the pentasilanes as fuels in combination with 98 % pure Rocket Grade Hydrogen Peroxide (RGHP) as the oxidizing agent. Chemical equilibrium compositions in the combustion chamber, nozzle throat and nozzle exit are presented and discussed with respect to variation of the equivalence ratio. Vacuum specific impulses and chamber temperatures are given in order to evaluate the rocket performance and are compared to hydrocarbon/RGHP as well as MMH/NTO bipropellant systems. The highly positive heats of formation of silanes lead to extraordinarily good theoretical performance of the system silanes/RGHP, being superior to the two more conventional systems regarding many aspects. To a certain extent, the heats of formation are also responsible for two additional, complementary possible applications, the use of silicon hydrides as high-energy hydrogen carriers for fuel cells, as well as means to easily produce thin semi-conducting, flexible, large-area silicon films with high mobilities.
