摘要： A swivel access structure for an engine nacelle, including a door plate, a first fastener, second fasteners, a door frame, and one or more flame shields. The door plate is selectively rotatable about the first fastener, and the second fasteners selectively release the door plate to allow its rotation about the first fastener from a closed configuration to an open configuration. The door plate is rotatably attached to the door frame via the first fastener. The door frame has a frame opening covered by the door plate when the door plate is in the closed configuration and exposed when the door plate is in the open configuration. The one or more flame shields cover an inner side of the door plate and/or an inner side of the door frame. The swivel access structure provides access within the nacelle without spring arrangements that are more susceptible to fail fire testing.

摘要： A method for manufacturing a composite part includes forming an initial radius filler on a composite panel. The initial radius filler is formed from a plurality of plies of composite material stacked on the composite panel. The method includes forming a radius of curvature on at least one side of the initial radius filler, positioning a composite stiffener on the composite panel, wherein the composite stiffener is contoured to define a radius gap when joined with the composite panel, positioning the composite stiffener against the at least one side of the initial radius filler, compressing the composite stiffener, composite panel, and initial radius filler via vacuum bag, and heating the initial radius filler to at least one of a cure temperature, a melting temperature, or a fusing temperature to form, from the initial radius filler, a radius gap filler in the radius gap.

摘要： A system and method for forming a composite part with multiple bends or curves, including placing an unformed composite laminate material onto a flexure and placing the flexure onto an engagement surface of a first forming tool. The flexure is a sheet of bendable material. The first forming tool has a first side surface, the first engagement surface, and a first corner between these surfaces. The flexure may have at least one thinned region aligned with the first corner. The method further includes sealing an impermeable membrane around the unformed composite laminate material, the flexure, and at least a portion of the first forming tool and heating them in an oven or autoclave. The method also includes applying a pressure differential to the impermeable membrane, pressing the unformed composite material and/or the flexure against the first side surface and to press the thinned region against the first corner.

摘要： A system for mounting an engine on an aircraft. The system includes a lower forward element, lateral linkages, an upper forward element, and an aft element. The lower forward element couples a forward portion of an engine core with a lower forward portion of a pylon. The linkages extend laterally between the lower forward element and the forward portion of the engine core. The upper forward element couples an outer portion of the fan case with an upper portion of the pylon. The aft element is spaced aftwardly apart from the lower and upper forward elements, and couples an aft portion of the engine core to an aft portion of the pylon. The system reacts all major moments acting on the engine, and the system does not extend beyond an outer periphery of the fan case, which eliminates the need for or minimizes the height of an aerodynamic fairing.

摘要： A method of manufacturing a multi-sided or otherwise relatively three-dimensional formed structure for, e.g., an aerospace vehicle. A relatively planar base structure is constructed using a first construction technique. Features (e.g., ribs) are incorporated into the base structure using a second construction technique (e.g., additive or subtractive manufacturing) to create an intermediate structure. The intermediate structure is folded along fold-lines or otherwise physically formed to create the formed structure, such that some of the features are located within an internal space defined by the formed structure. Joints between the sides of the formed structure are welded, fastened, or otherwise secured. Separately constructed additional elements (e.g., bulkheads) may be incorporated into the structure. A closeout element may be added to the formed structure to further define and close the internal space. Throughout the process, the structures, features, and elements may be refined to desired tolerances.

摘要： Methods of fabricating a multi-region U-shaped composite structure, the methods comprising the steps of laying up a first composite material on a first tool piece to form a first sidewall, laying up the second composite material on a second tool piece tool to form a second sidewall, re-orienting the first tool piece and the second tool piece to a consolidation orientation, laying up the third composite material to form a nose wall, and overlapping at least a portion of the third composite material with at least a portion of the first composite material and at least a portion of the second composite material.

摘要： A system for inspecting features of an airframe, the system including a feature inspection device configured to measure an aspect of a first feature and a tracking subsystem configured to determine a position of the feature inspection device when the feature inspection device measures the aspect of the first feature. The system is configured to determine a position of the first feature on the airframe via the feature inspection device and the tracking subsystem, the determination of the position of the first feature being independent from the measurement of the aspect of the first feature.

摘要： A ducted fan housing for directing a duct flow includes an annular cowling and an adjustable fan duct nozzle. The nozzle includes a flexible sleeve having rigid areas arranged circumferentially around the nozzle orifice and connected by flexible areas so as to form a unitary sleeve structure. The rigid areas are radially moveable between a normal configuration in which the orifice is smaller and a dilated configuration in which the orifice is larger. A drive mechanism uses drive elements to move at least some of the rigid areas between the configurations to adjust the size of the orifice. The rigid areas may be constructed from laminated graphite and epoxy, and the flexible areas may be constructed from laminated graphite and soft resin. If the housing includes a thrust reverser, then a flexible joint area extends circumferentially around the housing and connects the flexible sleeve to a thrust reverser cowl.

摘要： A method of bonding two or more metallic components into a single piece. The bonding surfaces of the metallic components are protected from reaction with the environment. A force is applied to the metallic components to push the bonding surfaces together. Simultaneous with applying the force, an electric current is passed through the bonding surfaces to joule heat and weld the bonding surfaces together to form the single piece. The bonding surfaces may be protected by plating with a noble metal, applying a coating, shielding with a noble gas, or placing into a vacuum. A press may be used to apply the force. The force and the electric current may be sufficient to push out metal around the joint of the bonding surfaces, and at least one of the bonding surfaces may be drafted to facilitate pushing out the metal. The electric current may be pulsed to induce electroplasticity.

摘要： A handheld device for making 3D topography measurements of surface discontinuities in high performance structures, such as aerostructures (e.g., aluminum fuselages). Lights illuminate the discontinuity from multiple angles, and a camera captures images of the discontinuity. A thickness sensor generates thickness data regarding a thickness of the base material and the top protective coating. A position sensor generates position data regarding a location of the discontinuity on the structure. A processor generates geometry data regarding a geometry of the discontinuity based on the images, performs an analysis of the geometry, thickness, and position data, and communicates a result of the analysis on a display. A conforming membrane and/or a gel and an opaque lubricant may be applied over and conform to the discontinuity in order to make more uniform a reflectivity difference and a color difference between the discontinuity and an adjacent portion of the structure.
