<p>A mounting assembly for mounting a rocket nozzle 17 to allow the nozzle to pivot about a pivot or gimbal point 55. The assembly comprises a fluid duct 58 for supply of fluid to the nozzle. The duct comprises two or more flexible fluid couplings 59a, 59b which intersect a common plane 36 on which the pivot is arranged. The fluid ducts may be formed by rigid materials. A consecutive pair of flexible fluid couplings of the fluid duct may be arranged orthogonal to one another about a central axis passing through the pivot point. Additional ducts may also be provided with two or three more flexible couplings, the ducts being offset from the common plane. The flexible couplings may be configured as bellow like couplings. The flexible couplings may comprise an external, or internal, gimbal arrangement. The flexible coupling additionally comprises a plurality of spaced annular elements (70, fig. 9) connected by a partial toroid element (43).</p> |
