Research and Simulation on the Technology of Submunitions Slowdown in the Air

The law of movement of the deceleration parachute submunitions is more complex than general aviation bombs.Then the law of movement of submunitions in parachute straightened,inflatable and stability phase is studied in this paper,and umbrella slowdown in the ideal fluid is established,and numerical simulation analysis is executed.Finally the process of changing the speed of submunitions is got.The conclusions could make reference to design and analyze in correlative projects.
