Abstract

Platforms () span between turbine blades () on a disk (). Each platform may be individually mounted to the disk by a pin attachment (). Each platform () may have a rotationally rearward edge portion () that underlies a forward portion () of the adjacent platform (). This limits centrifugal bending of the rearward portion of the platform, and provides coolant sealing. The rotationally forward edge (A,B) of the platform overlies a seal element () on the pressure side () of the forwardly adjacent blade, and does not underlie a shelf on that blade. The pin attachment allows radial mounting of each platform onto the disk via tilting () of the platform during mounting to provide mounting clearance for the rotationally rearward edge portion (). This facilitates quick platform replacement without blade removal.
