Abstract
The modified configuration of the 155 mm rocket assisted projectile equipped withlateral thrusters was proposed. Six degree of freedom mathematical model was used toinvestigate the quality of the considered projectile. Impact point prediction guidancescheme intended for low control authority projectile was developed to minimize thedispersion radius. Simple point mass model was applied to calculate the impact pointcoordinates during the flight. Main motor time delay impact on range characteristicswas investigated. Miss distance errors and Circular Error Probable for various lateralthruster total impulse were obtained. Monte-Carlo simulations proved that the impactpoint dispersion could be reduced significantly when the circular array of 15 solidpropellant lateral thrusters was used. Single motor operation time was set to be 0.025 s.Finally, the warhead radii of destruction were analyzed
