Abstract

In order to analyze the effect of dropping condition on water-entry parameters, the mathematical model of longitudinal trajectory for the parachute and object system was established Then, the Matlab/Simulink was used to carry on simulation research for the water-entry parameters under the influence of delivery parameters, and further analysis was made for the effect of delivery parameters in normal distribution on distribution of water-entry parameters. The result indicates that the delivery altitude not far above the ground plays an important role in water-entry parameters. The water-entry position is mostly affected by delivery velocity. Delivery carriage has little influence on water-entry parameters.

Key words： depth charge; parachute; delivery parameter; water-entry parameter
