Study And Simulation Techniques Of Cluster Adapter's Cabin Opening

The calculation and simulation of the cabin opening performance for the cluster bomb is an important research content in the study and application. In this paper, through further analyzing the structure of the cluster adapter, and studying the principle of the cabin opening, physical and mathematics models are established. In fact, during the process of the cabin opening, the most important factor is the parachute. Due to its higher resistance, the warhead is pulled. Based on some hypotheses, the flight system includes a bomb and parachute is taken as a variable mass-point system. The factors which consist of the variable mass, the added-mass and the acting force caused by them are considered elaborately. The mathematics models of free-falling process, parachute-pulling process, parachute-puffing and stable process of the cargo projectile system are established. The engineering calculating method to solve the mathematics model is also given. The simulation programme is written by visual C++. The simulation programme can be used to simulate airdrop course under various conditions, and to calculate dispersion of bomb's fall point and trajectory parameters. This programme can be used to optimize parameters of the cluster adapter and airdrop experiment. It is an effective analyzing means to the weapon system design and application.
