Title (EN) END-BURNING PROPELLANT GRAIN WITH AREA-ENHANCED BURNING SURFACE
(FR) BLOC DE POUDRE À COMBUSTION FRONTALE AYANT UNE SURFACE DE COMBUSTION AMÉLIORÉE EN SURFACE
Abstract: front page image
(EN)An end-burning grain of a solid rocket motor or other gas-generating device is supplemented with one or more sticks of high-burn-rate propellant embedded in a matrix of a relatively low-burn-rate propellant. The sticks increase the burning surface area as the grain burns by forming conical indentations in the surface.
(FR)L'invention concerne un bloc à combustion frontale d'un moteur à poudre ou autre dispositif à gaz auquel viennent s'ajouter un ou plusieurs bâtons de poudre à vitesse de combustion élevée se trouvant dans une matrice d'une poudre à vitesse de combustion relativement faible. Les bâtons augmentent la surface de combustion alors que le bloc brûle en formant des indentations coniques dans la surface.
