A primary seal assembly (200) for a variable area fan nozzle (VAFN) equipped turbofan engine includes a deformable seal (204) and a seal retainer (206) attached to the seal. The seal includes an inner wall (208) and webs (212) attache to the inner wall and extending transversely there-from. The inner wall and the webs extend circumferentially at least partially around a bypass duct (24) of the turbofan engine. An inner surface of the inner wall interfaces with the VAFN when the VAFN is in the stowed position. The seal (204) is compressed between the VAFN and the seal retainer (206) when the VAFN is in the stowed position. And each of the webs is deformed into a non-planar configuration when the VAFN is in the stowed position. |
