angle of fall
相关语句
  落角
     The results indicate that proportional navigation with over-gravity compensation is suitable for attacking fixed or less mobile targets,and especially for hitting the top of the target,for its angle of fall is greater and the line of sight at the point of impact has deflection and greater overload.
     结果表明,过重力补偿比例导引适用于攻击非机动和机动性不大的目标,落角增大,命中点附近视线偏转和控制过载变大,能够实现对目标的大落角攻顶效应。

Studies the oblique impact of a projectile against a thin target plate at a high-speed but small angle of fall.Applying the law of conversation of system momentum,some nonlinear dynamic impact equations are established.To solve these nonlinear dynamic equations,the central difference method is used.As an example,the impact of a D-35mm projectile against a thin target plate is analysed and calculated.

根据动量守恒原理,建立了弹丸以极大着角高速斜碰薄靶板时的动力学模型,并用中心差分法采解这些非线性动态方程。最后以瑞士双35炮弹为例进行了计算,并进行了图形仿真。

Physical and mathematical models for the perforation of a projectile in a target are established with the assumption that the target is half-infinite in size and made of hard soil or concrete,and that the angle of fall is form 0°to 90°.Through analysis of the spatial geometric relations of the perforation,the governing equatinns of the oblique perforation are given.Making use of a devoted program OIPHT,some dy-namic characteristics of the perforation process are calculated.Through actual tests,the limited...
