Abstract: An edge seal for preventing airflow through a space between a fan platform and an adjacent airfoil in a gas turbine engine may include a bonding segment being bondable to the fan platform. A sealing flap converges with the bonding segment so that the sealing flap is operatively contactable with the adjacent airfoil. A bumper rib protrudes from the bonding segment so that the bumper rib is bondable to the fan platform.
