Abstract
A flexible fan blade construction of the type wherein a decamber limiter is carried by each spider arm and bears against one side of its associated fan blade to thereby limit flexing (decamber) thereof. According to this invention, the decamber limiter terminates short of the heel of each fan blade. High stress concentrations due to contact between the heel edge of each fan blade and its associated decamber limiter are avoided by this novel construction.
