Ballistic opportunities' evaluation of artillery projectile with a rocket ramjet

Based on the analysis of existing technical solutions, promising structural designs of ammunition with rocket ramjet of 130, 152, and 203 mm caliber have been developed. Mathematical models of the ballistic functioning of artillery projectiles are implemented in software, which allow us to analyze the influence of design parameters on the ballistic functioning of active, active-reactive ammunition and ammunition with rocket ramjet. For ammunition of a promising scheme, a calculation was made of the support parameters and characteristic periods of the rocket ramjet, providing the possibility of increasing the firing range to 60 km or more. The carried out studies allow us to conclude that it is possible and advisable to develop long range projectiles equipped with an out-barrel dispersal system including rocket ramjet on paste fuel with or without solid propellant ramjet.
