    摘要: A variable exhaust nozzle (26) for a turbine engine nacelle (16) includes a pair of semi-cowls (58, 60) disposed about a longitudinally extending central axis (14) and a pair of corresponding shells (36, 38) each of which is spaced radially inwardly from the corresponding semi-cowl and is pivotable about a pivot axis (42, 44) between an extended position and a retracted position. The semi-cowls and shells have curved, geometrically similar inner and outer surfaces (86, 100) respectively so that gap (108) between the shells and the cowl is uniform irrespective of the angular orientation of the shells. A seal (128) which includes longitudinally extending legs (128a, 128b) and an optional circumferential leg (128c) prevents detrimental air leakage. Pivotal movement of the shells effects large changes in the discharge area A.sub.D of the nozzle without compromising the external aerodynamic characteristics of the nacelle. In one embodiment of the invention, each shell includes an extension (110) which facilitates the attainment of large area changes. The radial uniformity of gap (108) contributes to the durability and simplicity of the seal by ensuring that the seal is not repeatedly compressed and relaxed during operation of the nozzle.

    摘要: A flanged apparatus includes an apparatus body and a flanged mount, which includes a support pylon, a first mounting flange and a second mounting flange. The support pylon includes a first pylon segment, a second pylon segment and a routing notch. The first pylon segment is cantilevered from the apparatus body, and extends to the first mounting flange. The second pylon segment is cantilevered from the first pylon support, and extends from the first mounting flange to the second mounting flange. The routing notch extends vertically between the first pylon segment and the second pylon segment. The first mounting flange and the second mounting flange extend laterally from the support pylon, and the first mounting flange is separated from the second mounting flange by a longitudinal distance and a vertical distance.

    摘要: A linkage system includes a pivot bias assembly at each pivot which removes internal clearances and resultant vibratory wear. The pivot bias assembly includes a cavity which defines an axis transverse to the pivot axis. A spring biased piston is located therein to provide a radial load toward the rotation pivot to close radial clearances. The spring loaded piston reduces all the radial internal clearances to zero to reduce vibratory wear created by engine vibratory inputs. An assembly flat is positioned such that the component is assembled in a non-operating angular position such that the spring biased piston is under minimal or no load then the component is rotated into operating position so as to preload the spring biased piston.
