摘要： A geared turbofan engine includes a fan, a low pressure turbine, a geared architecture, and a nacelle. The fan and low pressure turbine are capable of rotation about an axial centerline of the gas turbine engine. The geared architecture connects the fan to be driven by the low pressure turbine. The nacelle is disposed circumferentially around the fan and defines a portion of a bypass flow duct. The nacelle includes a thrust reverser assembly with one or more doors that pivot to block at least a portion of the bypass flow duct in a deployed position.

摘要： A fan duct seal (68) for a gas turbine engine has at least one seal body (82) with a hollow center (84). A first opening (86) is formed in the seal body (82) that is in fluid communication with the hollow center (84). The first opening (86) is configured to receive fan air flow (90). A second opening is formed in the seal body (82) that is in fluid communication with the hollow center (84) such that cooling flow (92) enters the first opening (86), moves through the seal body (82) and exits from the second opening. A fan duct for a gas turbine engine and a method of cooling a fan duct seal assembly are also disclosed.
