Abstract
The energy capabilities of a hypothetical zwitterionic nitrohydrazine H3N+N-NO2 as a component of solid composite propellants are estimated. Two-component compositions with a hydrocarbon or active binder and three-component compositions with the addition of aluminum or aluminum hydride are considered. Compositions with an active binder and aluminum hydride show the highest calculated ballistic efficiency. Their specific impulse exceeds 280 s, and with allowance for two-phase losses, the maximum effective impulse of the third stage rocket motor, it reaches 265.4 s, whereas for an optimized similar composition based on ammonium dinitramide, this value is significantly lower (262.5 s).
