Abstract: An assembly includes a spherical bearing race and a spherical bearing element. The bearing race includes a race first segment, a race second segment and a bore that extends along an axis into the bearing race. The bore also extends radially within the bearing race between the first segment and the second segment. The bearing element is arranged within the bore, and radially engages the first segment and the second segment.

Abstract: Thrust variability in a nozzle is achieved by constructing the nozzle in two parts, one of which is rotatable relative to the other. The nozzle includes a convergent section, a throat, and a divergent section, all of which are formed in the annular region between a centerbody and a shell. The rotation produces a variation in the cross-sectional area of the nozzle by bringing apertures in the two parts into and out of alignment and thereby partially or fully opening and closing the flow passage through the convergent section, throat, and divergent section.
