Umbrella Bomb Group Spread Features

In the study and application process of cluster bomblet weapon system, the calculation and simulation of the ejection and disperses of bomblet performance is really an important research contents.In this paper, based on some hypotheses,the opening process of parachute is divided into four process. They are free-falling process, parachute-pulling process, parachute-puffing and stable process of the cargo projectile system respectively. The mathematics models are established.In the text, a method to measure the whereabouts track of a parachute bullet cluster which adopt CCD high speed camera is introduced. Through the analysis of the obtained picture, the actually trajectory is gotten. Through correction the parameter and dynamics model of parachute system, the theories analysis and experiment result are consistent.On this foundation, Monte Carlo method is used for the random simulation computation of parachutes. Through simulation calculation, the main parameter is gotten which influence the dispersal regulation of this system. The textual point is to optimize parameters of the cluster adapter. It is an effective analyzing means for the design and application of weapon system.
