Abstract : The main parachutes drawn down by a pilot parachute is the generally used method of the jettison of air bomb with bomblets and their interaction process is the basis and key for the bomb projection. A mechanical model loaded by the string of pilot parachute is theoretically established, and under different projection velocities, the design method of the length and strength for the string of the pilot parachute is suggested. The results show that for a certain 500 kg air bomb, if the projection velocity is 222 m/s and the strength of the string is 5000 N, the length of the string 3 m cannot meet the requirement.
