Abstract

L'engin autopropulsé comprend un étage de propulsion 1 comportant une paroi avant 3 et une tuyère 4 reliées par un corps cylindrique 5 renfermant un chargement pyrotechnique 7. Le corps cylindrique 5 est entouré par un chargement pyrotechnique périphérique 9 coaxial avec le premier chargement 7 et la tuyère 4 comprend une surface intérieure annulaire et convexe constituant une tuyère centrale 12 pour le chargement pyrotechnique 7 contenu dans le corps cylindrique 5 et une surface extérieure également annulaire et convexe constituant une tuyère périphérique 13 limitée latéralement par la paroi du tube de lancement 2, pour le chargement péripherique 9. Application aux roquettes.
