Abstract: The features and working Principle of piston-type firework connection and separationdevices for manned vehicle were introduced in this paper. The separation process of device was described with a theoretical model. The separation force and separation speed during device separationwere obtained. The principle and method for determining the optimum powder mass were discussed.The accuracy of predication performance of devices to has been studied experimentally. The method isof great value to engineering application.
