Influence of Selected Initial Disturbances into the Lateral Scattering of a Supersonic Mortar Projectile
Journal Title: PROBLEMY TECHNIKI UZBROJENIA - Year 2018, Vol 148, Issue 4
Abstract
Influence of selected initial disturbances into the lateral dispersion of a supersonic mortar projectile, developed in the frame of RAK MUNITIONS program, is analysed in the paper. In the first part of the paper some factors which may influence the lateral dispersion of mortar projectiles are indicated. Such parameters of the projectile as initial lateral velocity, initial angle of yaw and initial velocity of the yaw angle, and an unexpected lateral gust of wind were analysed. In the next step the possi-ble values of disturbances for these parameters were estimated to perform the calculations for these values at the muzzle velocity of v0=500 m/s. The calculations were performed by using a model of flight with five degrees of freedom which was developed for the mortar projectiles. The results of calculations were compared with the analytical results received with a relation presented in the literature for values of aerodynamic jump. The conclusions are presented in the final part of the paper.<br/><br/>
