ABSTRACT:
The combustion chamber of the thruster comprises a tubular structure of composite material, at least one end wall applied to an end of the tubular structure, and a sealed connection device between the tubular structure and the end wall. The connection device includes mechanical connection means comprising smooth-walled studs engaged through the tubular structure and the end wall so as to provide connection in an axial direction and in its circumferential direction, together with stud retaining means operating in a radial direction. A sealing gasket is interposed between the end wall and an annular intermediate part forming a gasket bearing member secured to the end wall in the radial direction in such a manner as to keep the gasket compressed in the event of the end wall deforming.
