    摘要: The horsepower requirements for the actuation system for a convergent/divergent exhaust nozzle for a gas turbine engine is reduced by the judicious selection of the crank arms and their location on a torque shaft that rotates to move a connecting link attached to the convergent flap of the nozzle. A pressure balancing hood is attached to the top surface on the forward end of the convergent flap to augment the lowering of the horsepower requirements. In another embodiment a tie rod/end cup arrangement and two piece torque shaft are utilized for ease of removal of the actuation system from the exhaust nozzle assembly.

    摘要: A paired vane structure for the first stator stage of a gas turbine, having the vane structure of each vane pair cast in two matching parts which are then assembled and held together by means of bolts passing through flanges on the vane inner and outer platforms. The paired vanes are assembled into the gas turbine structure in the same manner as the prior art paired vane sections.
