Publication number: 20190113426Abstract: Systems and methods of operating a test apparatus to simulate testing a production aircraft component include assembling a test assembly having a test specimen and a wear protection material disposed on opposing sides of the test specimen, an outer plate disposed on each side of the test specimen in contact with the wear protection material, and a bolt disposed through the test specimen and the outer plates and applying a preload against the wear protection material. The test assembly is secured in a test machine, and the test machine is operated to provide a predetermined displacement of the test specimen relative to the outer plates at a predetermined frequency at a determined frequency of displacement cycles. The preload, the predetermined displacement, and the predetermined frequency of displacement cycles are determined through finite element analysis of an analytical model of the production component.Type: ApplicationFiled: October 12, 2017Publication date: April 18, 2019Applicant: Bell Helicopter Textron Inc.Inventors: Andrew Paul Haldeman, Ramesh Thiagarajan, Suvankar Mishra

Publication number: 20180244397Abstract: An aircraft fuel system includes one or more fuel cells adapted to contain fuel, a fuel cell receiving assembly having an inner surface adapted to receive the one or more fuel cells and a fuel cell cushion disposed between the inner surface of the fuel cell receiving assembly and the one or more fuel cells. The fuel cell cushion is machined from a foam substrate to form a shaped foam substrate that is substantially covered with a cushion coating. The cushion coating is sprayable onto the shaped foam substrate such that the fuel cell cushion is substantially nonabsorbent of fuel. The fuel cell cushion is interposable between the inner surface of the fuel cell receiving assembly and the one or more fuel cells to cushion the one or more fuel cells from damage.Type: ApplicationFiled: February 27, 2017Publication date: August 30, 2018Applicant: Bell Helicopter Textron Inc.Inventors: Timothy Brian Carr, Suvankar Mishra, Michael Stephen Deslatte, Michael Douglas Ishmael, Ronald James Turner

Publication number: 20180141246Abstract: A composite structure includes a first face sheet, a second face sheet, and a foam member located between the first face sheet and the second face sheet. The foam member has a molded contour, the mold contour being configured to provide tooling surface for at least one of the first face sheet and the second face sheet prior to curing of the composite structure. A method of making the foam member includes creating a mold tool having an interior surface which resembles the desired outer contour of the foam member. A mixture is poured into a pour opening in the mold tool. The mixture is allowed to polymerize into a foam as the foam expands and distributes within the mold tool. Vent openings in the mold tool are selectively tailored to control the density of the foam member. The foam member is cured in the mold tool.Type: ApplicationFiled: January 16, 2018Publication date: May 24, 2018Applicant: BELL HELICOPTER TEXTRON INC.Inventors: Suvankar Mishra, John R. McCullough, Mark Chris, Stanley B. Woychesin

Publication number: 20160303818Abstract: A structure includes a skin and a foam member. The foam member has a molded contour, the mold contour being configured to provide tooled surface for the skin. When the skin is a composite skin, the foam member provides support for the skin so that the skin can be cured under heat and pressure. A method of making the foam member for a foam stiffened structure includes creating a mold having an interior cavity which resembles a desired shape the foam member. A subsequent step involves introducing a foam mixture into the mold. Next, the foam mixture is allowed to polymerize so as to expand and distribute within the cavity of the mold. The method further includes selectively controlling a density of the foam member in the mold. The foam member is at least partially cured. The foam member is assembled with a skin to produce the foam stiffened structure.Type: ApplicationFiled: June 28, 2016Publication date: October 20, 2016Applicant: BELL HELICOPTER TEXTRON INC.Inventors: Ramesh Thiagarajan, Suvankar Mishra, Mark Chris, William Evans, III, Mike Mikel
