Optimization method of ballistic blast fragmentation warhead striking aircraft in aircraft shelter

Abstract

For evaluating the economy and feasibility about blast fragmentation warhead striking aircraft in aircraft shelter, taking a typical aircraft and single/double aircraft shelter as study objects, based on the thought of simple/quadratic surface fitting, the 3D surface models of aircraft and shelter are built. According to the velocity and position model of fragment, combined with the transformation relationship of coordinate system, the missile-target encounter algorithm is given. The ruin tree model of aircraft is constructed to calculate the ruin probability algorithm of aircraft. For reducing the computation of missile-target encounter, a mean ruin probability algorithm of aircraft based on integration method is proposed, which slices target area to grids and takes grids as alternative aim point. Taking maximum to entire ruin effect of all aircrafts as target, the optimizing algorithm to strike scheme about minimum missile consumption and find best aim point based on advanced PSO algorithm are proposed. The striking scheme optimizing about fragmentation warhead striking aircraft in single/double aircraft shelter is simulated. The result shows that, low blast height, small CEP, combination strike strategy with multiply aim points can reduce the minimum missile consumption effectively.
