Abstract: A two-dimensional nozzle is disclosed wherein outward deflection of the sidewalls is controlled by using the load force of the divergent actuators to produce a bending moment within each sidewall which opposes such outward deflection.
Abstract: A flexible fairing 13 is provided which includes an aerodynamic surface 20 composed of a plurality of closely spaced, telescopic fairing members 14 and a moveable fairing panel 18. One end 15 of each fairing member 14 is pivotably secured to a divergent flap 11 of a thrust vectoring nozzle, and the other end 17 of the fairing member is pivotably secured to the fairing panel 18 which is slideably mounted to the static structure of a nozzle 19 of a gas turbine engine. The flexible fairing 13 adjusts to accommodate both translational and rotational movement of the divergent flap relative to an airframe fairing 10, thereby maintaining an aerodynamic surface 20 between the airframe fairing 10 and the divergent flap 11 of the nozzle.
Abstract: The present invention provides a method and means for maintaining metal parts in fixed relation to each other throughout a brazing cycle. The fixed relation is maintained by supporting the parts on concentric support rings made of the same alloy as the parts. The support rings lie within backup rings which exhibit high creep strength at the temperature necessary to braze the parts. The backup rings are slideably supported on a base, and a cover is provided which cooperates with the base to prevent furnace contaminants from contacting the parts during the brazing cycle.
Abstract: A buffing guide includes a mating surface, a first guide surface, a second guide surface and means for engaging an airfoil root. The buffing guide directs a buffing wheel into precise contact with a root edge at a point where selective contouring is desired, with sustained contact providing a smooth radiused surface while avoiding the detrimental effects of grinding or milling operations.
