Abstract

L'invention concerne un dispositif d'éjection à piston rétractable. Ce dispositif est caractérisé en ce que le piston contient une charge pyrotechnique munie d'une amorce, et une masselotte équipée d'un percuteur et susceptible de venir frapper l'amorce par effet d'inertie en fin de course du piston de façon que les gaz dégagés par la combustion de la charge pyrotechnique assurent le retour du piston jusqu'à sa position rétractée. Application au largage et à l'éjection de charges telles que des bombes emportées sous avion ou sous hélicoptère.
