Abstract
A propulsion chamber for a liquid propellant rocket engine is provided. The propulsion chamber includes an inside wall made of metal, an outside covering made of organic matrix composite material, and a cooling circuit arranged between the outside covering and the inside wall. The propulsion chamber further includes at least a first axial endpiece secured to the metal inside wall and presenting at least one radial protrusion received in a concave recess in an inside face of the outside covering. The concave recess is situated axially between first and second belts of reinforcing fibers oriented substantially circumferentially in the outside covering in such a manner as to take up forces associated with inside pressure and thrust.
