Abstract
The feature of the aerodynamic interference wind tunnel experiment for submunition and the composition of the experiment devices are introduced in this paper. Using this scheme, the dispenser-submunition aerodynamics interference experiment was carried out. The experiment results show that the interference of the drag coefficient and the lift coefficient vary violently as the axial position changes, and decrease as the submunition movement away from the dispenser in vertical direction. The angle of attack of the submunition doesn't play a role in the aerodynamic interference. The aerodynamic interference is very strong in the zone of the dispenser's empennage. The dispenser's wake affects the drag of the submunition acutely. It should be studied in detail that how to define the boundary of the aerodynamic interference zone for the dispenser and submunition in the subsonic flow.
