摘要： A method of making ducts having outwardly extending ribs formed integrally with the duct structure. Two tubes are formed from fiber reinforced resin materials, a uniform inner tube and a ribbed outer tube, then the inner tube is bonded with in the outer tube to form a high strength ribbed duct. An outer tube is formed by placing resin impregnated fibers over a cylindrical mandrel having an inflatable bladder on its surface, placing a plurality of spaced rings tightly against the outer surface, pressurizing the bladder to expand the tube into the spaces between rings to form low ribs, then gradually moving the rings toward each other to press the ribs therebetween and form thin upstanding ribs. The inner tube is formed by placing resin impregnated fibers on a slightly thinner mandrel that also has a surface bladder. When both tubes are formed, the mandrel is removed from the outer tube and the inner tube and mandrel are inserted therein and the inner tube bladder is inflated. The assembly is vacuum bagged and cured in an autoclave at a suitable temperature. The rings and mandrel are then removed and an integrally ribbed duct results. The thermosetting or thermoplastic resin impregnated fiber material may be placed on the mandrels by any suitable means such as filament winding, hand lay-up, or other deposition techniques.

摘要： A pivot door type aircraft turbine engine thrust reverser which includes a pair of pivoting panels on the inner side of the door. The panels are positioned alongside the door actuation mechanism. The panels form a flush surface along the fan duct flow path when stowed during normal engine operation in flight. When the door is deployed in thrust reversing mode, one end of the door moves to at least partially block airflow through the duct and divert it out along the door through an opening uncovered by door deployment. During door deployment, a linkage moves the panels toward the outer surface of the door, exposing a door deflector plate to the airflow. Air flows along the door, then along the panel, out through the opening, then impacts the deflector plate which deflects the airflow in the reverse direction.

摘要： An engine shroud with integral honeycomb panel corners for use in the thrust reverser region of ducted fan gas turbine engines. The integral shroud is useful in a turbine engine having a core engine surrounded by an engine casing and nacelle, with a fan at the inlet directing air flow into the bypass duct between core engine and engine nacelle. The shroud basically consists of right and left ducts each having an approximately semicircular cross-section with radial flanges extending from the duct edges. The flanges permit the halves to be fastened together to produce a tubular shroud adapted to surround a gas turbine engine and form the inner wall of a bypass duct. The disclosed shroud eliminates the prior complex corner fittings connecting the semicircular center portion of the shroud to the extending flanges and provides simple, integral corners.

摘要： An improved synthesis for PMR-type polyimides, including first preparing a dimer of 5-norbornene-2,3-dicarboxylic acid, or acid ester or anhydride and 4,4'methylenedianiline. This dimer is then reacted with the reaction product of the dimethyl ester (or dianhydride) of 3,3', 4,4'-benzophenonetetracarboxylic acid and 4,4'-methylenedianiline. The resulting polyimide prepolymer exhibits superior physical properties and is substantially free of the undesired trimer of 5-norbornene-2,3-dicarboxylic acid, or acid ester or anhydride and 4,4'-methylenedianiline. When this dimer is reacted with 3,3', 4,4'-benzophenonetetracarboxylic acid dianhydride methylenedianiline amic acid mixture, the resulting polyimide prepolymer exhibits superior physical properties.

摘要： A method and apparatus for draw forming a metal sheet over a male form to produce a three-dimensional shape. A sheet of metal is clamped between upper and lower draw plates positioned above the male form. The upper plate has an edge conforming to the male form shape. The plates and sheet are moved downwardly over the form with the edge of the upper plate firmly pressing the sheet against the form. The clamping pressure between the draw plates allows suitable slippage as drawing proceeds to produce a drawn shape of intended thickness. The drawn shape has a configuration conforming to the outer surface of the male form and has an outer surface of improved uniformity and appearance due to the wiping action of the upper plate edge.

摘要： The invention is directed a laminate structure using a reticulated adhesive material positioned between the honeycomb core and a perforate sheet and a precured reticulated adhesive between the perforated sheet and an outer layer of wire screen or other porous fibrous materials with similar pore openings therethrough through which the cells of the honeycomb core can communicate the atmosphere adjacent to the opposite side of the outer layer of porous material and a method of manufacturing same. During the manufacturing process of honeycomb noise attenuation structures which includes an imperforate sheet, an open cell honeycomb core, a perforated sheet and a layer of porous material stacked in that order a thin sheet of a reticulative adhesive material is positioned between the honeycomb core and perforated sheet and between the perforated sheet and the outer porous layer. During reticulation the reticulative material by its physical makeup shrinks to the edges of the perforations of the perforated sheet thereby leaving the perforations of both sheets of material open to the cells providing a bonding agent between the honeycomb core and perforated sheet and a similar precured layer providing galvanic isolation between the porous sheet and the perforated sheet.

摘要： An improved method of superplastic forming comprises the steps of selecting a relatively larger driver sheet and a relatively smaller part blank, both being made of Titanium, Titanium alloy or other metal capable of exhibiting superplasticity. A ceramic die is placed on a bottom wall of an upwardly opening ceramic forming chamber having sidewalls with upper edges. The ceramic chamber has an outer supporting steel jacket. The part blank is positioned over the die. The driver sheet is positioned over the part blank so that the peripheral edges of the driver sheet rest on the upper edges of the sidewalls of the forming chamber. A cover is provided for closing the chamber. It has a peripheral seal extending from an underside thereof. The cover and the chamber are clamped together in order to impinge the seal into a periphery of the driver sheet. The driver sheet and part blank are then heated to a predetermined temperature at which they exhibit superplasticity. Next a pressurized inert gas is introduced into an interior formed by the closed cover and chamber and thereafter released so that the driver sheet presses and forms the part blank around the die. The peripheral edges of the part blank are free to draw in during the forming to thereby avoid any undesired necking or thinning. The cover is lifted from the chamber and the formed driver sheet and part blank are removed.

摘要： A filament winding payoff unit and process for applying strands of adhesive impregnated filament material arranged into a gap-free band to a rotating mandrel. A plurality of side-by-side slightly overlapped impregnated filament strands are passed over bars between tines of combs for positioning when leaving the payoff head. The payoff head is positionable toward and away from the rotating mandrel to allow for mandrel longitudinal dimension changes while maintaining the payoff head roller in contact with the mandrel at a predetermined pressure thereagainst. The payoff head is also freely pivotable horizontally to maintain a proper angle of filament application to any changing mandrel longitudinal configuration.

摘要： The invention is directed to an improved hopper for feeding abrasive material of very small grit size to a cutting head. The device comprises an open hopper vertically disposed with a transverse positioned pick-up tube located in the lower portion of the hopper. The pick-up tube has a tubular center with a necked down diameter intermediate of its's ends. An opening extends from the bottom of the tube into the tubular center at a location centered in the necked down portion thereof. One end of the tube is vented to atmosphere through an adjustable orifice and the other end is connected to a source of low pressure created within the mixing chamber of the nozzle body assembly by high pressure water passing across the open end of the tube. This effect causes abrasive grit to be drawn through the opening in the bottom of the tube out the low pressure end of the tube to the cutting head. The flow of abrasive is regulated by controlling inlet/outlet air stream mass air flow or in combination with varying abrasive inlet sizes. The device is a passive, demand system, eliminating the need for mechanically controlled abrasive flow.
