A numerical model for suspender ejection device with the powder gas of blank cartridge as driving energy is established. The whole dynamic process from the burning of the blank cartridge and the unsymmetrical motion of the ejection piston, to the complete pushing away of suspender (missile or bomb) is simulated. The influence on the unsymmetrical ejection effect by the adjustment of the left and right gas port diameters is analyzed. It is shown that the flying attitude of the suspender leaving battleplane can be changed by adjusting the gas port diameters of both sides, so as to eliminate the abuse of larger angular velocity and displacement caused by the centroid offset of different suspenders. The model settles a basis for the self-adaptation control and optimum design of such a type of ejection device.
