Abstract
This device concerns missiles and in particular those made up of a payload stage in the form of a sub-munitions cargo-container and a propulsion stage. It is intended for the separation and aerodynamic braking of the propulsion stage at the end of its operation so that the sub-munitions can be released without the risk of hitting it. It includes attachment by fitting and locking by shear screws of the two parts of the missile, an inflatable bag arranged in an annular housing, a mobile piston used to separate the two parts of the missile, an initiatable gas generator driving the mobile piston then inflating the bag, means of initiating the gas generator consisting of a primer and firing pin and sensitive to a drop in pressure of the gases in the propulsion stage.
