Title
(EN) SOLID BOOSTER FOR A LAUNCHER
(FR) PROPULSEUR SOLIDE POUR LANCEUR
Abstract
(EN)
Solid booster (14) for a launcher, the booster being suitable for being separated from the rest of the launcher and comprising a wall (18) defining a combustion chamber (19) comprising an end, termed a front end (19a), and an opposite end, termed a rear end (19b), propellant (24) arranged in the combustion chamber, a combustion channel (26) passing through the combustion chamber from the front end toward the rear end, a nozzle (22) arranged at the rear end of the combustion chamber, an ignition (28) closing off the combustion channel at the front end of the combustion chamber, a skirt (20) covering the ignition at the front end of the combustion chamber, the skirt allowing the mechanical link with the rest of the launcher, and an ignition ejection system (34, 36, 38).
(FR)
Propulseur (14) solide pour un lanceur, le propulseur étant adapté pour être séparé du reste du lanceur, et comportant une paroi (18) définissant une chambre de combustion (19) comportant une extrémité dite avant (19a) et une extrémité opposée dite arrière (19b), du propergol (24) disposé dans la chambre de combustion, un canal (26) de combustion traversant la chambre de combustion depuis l'extrémité avant vers l'extrémité arrière, une tuyère (22) disposée à l'extrémité arrière de la chambre de combustion, un allumeur (28) obturant le canal de combustion au niveau de l'extrémité avant de la chambre de combustion, une jupe (20) recouvrant l'allumeur à l'extrémité avant de la chambre de combustion, ladite jupe permettant la liaison mécanique avec le reste du lanceur, et un système d'éjection (34, 36, 38) de l'allumeur.
