Abstract
In an axial flow compressor rotor stage having a tangential slot in the periphery of the rotor to receive the blade roots, a seal is positioned below the blade platforms to seal these platforms against air recirculation. The seal extends under the platforms of several blades and is ladder shaped with the rungs sealing the platform spaces and the struts serving to interconnect and hold the rungs in place.
