Abstract:
The energy capabilities of a hypothetical zwitterionic nitrohydrazine H$_3$N$^+$N$^-$NO$_2$ 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 $\approx$33% for a 152-mm howitzer and by $\approx$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 $\approx$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.
Keywords:nitrohydrazine, ammonium dinitramide, mixed powder, powder force, powder potential, initial projectile velocity, muzzle energy of the projectile, ballistic efficiency of the shot.
