Abstract
Fan blades of a rotor stage do not have platforms and separate wall members are provided to bridge the space between adjacent blades with the wall members defining an inner wall of a flow annulus through the rotor; each wall member has a plurality of hooks which extend radially inwardly to engage correspondingly shaped hooks provided on the radially outer face of the disc and further hooks engage rings mounted on the rotor adjacent to the disc to lock the wall member in position and insure that the hooks on the wall member engage the hooks on the radially outer face of the disc.
