Abstract
A fan engine having a core engine and a fan duct has bleed ports positioned circumferentially around the compressor housing of the core engine to bleed flow into the fan duct. A strap covers the circumferential line of holes and it is moved between an open and closed position by a U-shaped flexure element which biases the bleed port seal strap to an open position while an actuator moves the seal strap to a position to close the bleed ports. The ends of said U-shaped flexure elements are connected to the ends of the seal strap and are connected to links which insure that the ends of the strap are moved in a predetermined path.
