New combinations of energetic compounds for creation propellant for additional propulsion jet systems

摘要

Proposals to reduce anthropogenic pollution on environment because of separating parts of space launch vehicle and upper stage (boosters) with liquid propellants are under consideration. Residual energetic sources that can not be used directly are gasified before being feeding into combustion chamber of gaseous rocket engine. The energy (specific impulse) increases due to use of high energy additives (aluminum- and boron compounds containing hydride groups, e.g. aluminum hydride, dimethylaluminum hydride, pentabo-rane) together with classic liquid components (kerosene, liquid oxygen, asymmetric di-methylhydrazine, liquid nitrogen oxide N_2O_4 etc.). 10% of such energetic additive increases the specific impulse value in up to 10 kG-s/kg in comparison with the initial liquid propellant formulation. Therefore the rocket velocity increases considerably (in up to ~ 50 mis, that is about 10% of initial velocity).
