ABSTRACT:
The transition piece seal spring includes a pair of integrally formed spring clips folded at one end to define a support slot, the spring clips being disposed in back-to-back relation one to the other. Each spring clip includes a pair of elongated, arcuately disposed spring segments spaced one from the other defining a slot for receiving the outwardly directed flange of the transition piece edge. A flat leaf spring is received in the support slot and mounts the spring clip to the first-stage turbine outer nozzle support ring such that the spring clips depend radially between the flanges of adjacent edges of the transition pieces. The spring clips enable radial, circumferential and axial vibratory movement of the adjacent transition pieces whereby motion is taken up in high cycle fatigue rather than wear.
