Abstract: PROBLEM TO BE SOLVED: To decrease the flow of a fluid between adjacent fan blade platforms and maintain the fan blade easily. SOLUTION: This seal is inserted between platforms 46 of a blade 34 for a fan of an axial-flow gas turbine engine. In this case, a present shock resistant fan blade 34 has a big inter-platform gap, so the big gap of the inter-platform 46 must sealed. The seal is reinforced so that it may endure a centrifugal force by the movement of the fan.

Abstract: PLATFORM SEAL-TANGENTIAL BLADE 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.
