    Abstract
  • In order to study the problem of preliminary ballistic deflection when a penetration warhead with truncated ovate nose penetrates target obliquely, the theoretical model and simulation model are set up to analyze the effects of truncated ovate nose diameter on the preliminary ballistic deflection of penetration. The defection function and deflection angular velocity of warhead penetrating target are calculated in the same penetration condition with different truncated ovate nose diameters. It is concluded that the angle between axis of warhead and normal of target decreases with the action of deflection moment caused by the warhead of truncated ovate nose penetrating target. Both the deflection moment and the deflection angular velocity increase with the increase of truncated ovate nose diameter. When the truncated ovate nose diameter increases to 1.5 times, the deflection moment will increase to about 1.2 times. When the truncated ovate nose diameter increases to 2.0 times, the deflection moment will increase to about 2 times. Under the condition of the same truncated ovate nose diameter, the defection moment and the deflection angular velocity are increased with the shape coefficient of warhead.
