Abstract
The energy capabilities of a hypothetical zwitterionic nitrohydrazine H3N+N-NO2 as a component of artillery propellants are assessed. Compositions with a hydrocarbon binder, compared to standard propellant charges, allow increasing the muzzle energy of a projectile by ≈33% for a 152-mm howitzer and by ≈27% for a 125-mm tank gun without increasing the temperature of the propellant gases. For a 120-mm mortar, the increase in the muzzle energy of a mine is ≈14%. Similar compositions based on ammonium dinitramide are considered for comparison, which have shown lower efficiency. Compositions with an active binder also achieve high performance indicators. However, they have a high temperature of combustion products, which is unacceptable for most barrel systems.
