A propulsion unit 2 for the acceleration of a missile 1 comprises a body 7 connected by a shear connection 6 to a cruising stage of the missile and supporting a propellant charge consisting either of tubular elements 10, 11 stuck on an inhibiting ribbon 13 which is spirally wound or plates of propellant arranged in the form of a star, the charge being located within a cylindrical envelope formed, as shown, by a launching tube 3 without a nozzle and closed at the rear end by a frangible cover 20. The charge is initially ignited under conditions which permit a stable combustion of the propellant, the charge continuing to burn for a duration of less than one second under conditions which theoretically correspond to an unstable combustion of the propellant. Maximum and minimum values for the ignitable surface area of the propellant are specified. <IMAGE> |
