Abstract
The present invention relates to a seal interposed between platforms of blades for a fan in an axial gas turbine engine. Modern impact resistant fan blades have larger interplatform gaps. As a result, the interplatform seals have to seal a large gap. The seal is stiffened such that it can withstand centrifugal forces due to fan operation. In addition, various construction derails are developed for the stiffened seal.
