摘要

The jet nozzle for a rocket with solid fuel has a reinforcing extending in the circumferential direction of the nozzle structure and provided with a heat insulation on the outer side of the nozzle structure. The reinforcing (7,8) is fastened on the inner contour of the nozzle structure (3) and consists of a fiber material with the fibers orientated in the circumferential direction. At least the converging section (5) of the nozzle structure is provided with the reinforcing.
