Abstract

The development of bipropellant rocket motors based on hypergolic "green" propellants, kerosene and hydrogen peroxide, is described. These are similar in performance to the established monomethyl-hydrazine (MMH) and nitrogen-Tetroxide (N2O4) based bipropellant thrusters. This "green" patented hypergolic concept was developed using gelled fuel, containing some reactive particles, and concentrated hydrogen peroxide (HTP) as oxidizer. The results of firing tests of various models of thrusters showed very robust hypergolicity and short ignition delay times, in the order of milliseconds, with estimated characteristic velocity efficiency (ηC*) exceeding 98%.
