The dynamic behavior of bomb-parachute systems is extremely complex. By synthesizing and applying principles and analytical methods of parachute dynamics and multi-body dynamics, the nine-degree-of-freedom dynamic models of terminal descent of bomb-parachute system were developed.
The model validity was verified by comparison with flight test data. The simulation program was de?veloped to analyze moving characteristic of bomb attitude and moving law of scanning point under wind gust. The result in above research can be applied to the design of bomb-parachute system and the guid?ance of its aerial delivery test.
