Abstract
Pyrotechnic igniter capable of being fitted in, and withdrawn from the throat of the nozzle of a propulsion unit. The igniter comprises parts bearing on the convergent section (1a) and on the divergent section (1b) of the nozzle. In order to permit the fitting and the withdrawal of this igniter at any time, while improving the conditions of ignition of the propellent charge, the igniter comprises, on the one hand, an internal rupture member (2) and, on the other hand, external means of fitting (3) which are capable of expanding radially, this internal rupture member initially maintaining the external means of fitting in a deployed position.
