Calculation method of blockage probability on airport based on fragment shot-line

The calculation method of blockage probability of the takeoff plane blocked by the fragment blockage warhead was proposed. The beating area of warhead damaging takeoff plane was analyzed. The model of falling points of cluster munition, the mathematical model of initiating time of submunition and the calculation model of fragment were built. The probability of fragment blockage cluster munition blocking takeoff plane was obtained. The calculations of shot-line of fragment warhead and blockage probability were achieved based on VC and MATLAB. With the calculation, and the method of blockage probability based on the fragment strike-line, the space distribution of all fragment can be quantitatively analyzed. The flying direction and energy attenuation of every fragment can be described intuitively, so that the damage effects of fragment attacking the target can be accurately evaluated. The calculation model offers reference for the design of combat plan of fragment blockage warhead and the evaluation of blockage efficiency.
