And the improved fall point simulation will be consistent with the bullet s real fall point distribution.

In this paper, the conversion from bullet image point s film coordinate to its space coordinate is realized by the coordinate conversion method.

According to the make-up of small caliber submunition,the loading form of bullets and the principle of explosion,spacial movement model of bullets after explosion is established and simulated,the relation between bullets barrage and above factors is obtained,the academic basic to improve damage effect and optimize the frame of ammunition is made.

Aiming at the problems such as the failure of submunition in flight and the lack of evaluated subsamples in range test of tactical missile,a flight dynamics model of submunition is provided through analyzing the motion law of submunition and the influence of environmental factors and the aerodynamic factors.

The efficiency of submunitions is affected directly by its flying stability.

Aiming to high reentry velocity of tactical ground-to-ground missile and deceleration demand of submunitions.

The article respectively gives the radius of bomblet dispersion s equivalent eirtle and determmation and evaluation methods on dispersion homogeneity quotas based on the assumption condition of homogeneous dispersion by means of normal distribution.

The Way of Improving the Anti-personnel Performance of the Anti-armor and Anti-personnel Dual Purpose Grenade;
