ABSTRACT:
1. A rocket motor having a body and an exhaust nozzle which comprises a tubular main part fixed to the motor body and a hollow nozzle extension containing the nozzle mouth, with an exhaust axis, the extension being sealed to the main part of the nozzle by means of a universal joint of the spherical ball-joint type, a gimbal ring supported by the body of the motor and pivotally connected thereto about a first pivot axis transverse to the nozzle exhaust axis, the nozzle extension being pivotally supported in the gimbal ring for pivotal movements about a second pivot axis transverse to the nozzle exhaust axis and normal to the said first pivot axis, means for turning the gimbal ring relative to the motor body about the first pivot axis, including first actuating means with a first linkage operatively connected to the gimbal ring, and means for independently turning the nozzle extension relative to the gimbal ring about the second pivot axis, including second actuating means with a second linkage operatively connected to said nozzle extension, said second linkage including a first shaft supported in a bearing carried by the motor body for rotation about a fixed axis perpendicular to said first pivot axis, a second shaft supported by the gimbal ring on an axis parallel to said second pivot axis and operatively connected to said nozzle extension, and a universal coupling whose center lies on said first pivot axis, operatively connected between said two shafts.
