【Abstract】 Safe separation of vehicle launched from carrier is a key technology for captive on top airlaunched system. A captive-on-top project choosing IL - 76 as the carrier is studied in this paper. A dynamical mathematical model for the separation is set up. The aerodynamic force during the separation is calculated through the way of CFD method, and characteristic point method is applied to collision judgment. The results indicate that the separation of vehicle launched from the carrier can be achieved successfully and no collision occurs during the separation.更多还原
