Final report. -Aberdeen: Army ballistic research lab, 1984, - 48 р.
An experimental program to determine the magnitude and nature of the launch perturbations to the projectile angular motion during sabot discard is discussed. The data analysis isolates the sources and quantifies the severity of the launch perturbations. An explanation of how the discard dynamics may be related to the inbore motion of the round is presented. The results show that the discard disturbances cause a net increase of 41% in the level of first maximum yaw. For the different configurations tested changes in the inbore contribution to first maximum yaw indicate that the structural design of the front boreriding system is critical to the inbore behavior. A correlation is given between the angular rate to angle ratio at the muzzle and the severity of the discard interactions. Based on the correlation an alternate launch philosophy is necessary for APFSDS ammunition to assure on target accuracy.
