Patent number: 7837148Abstract: Embodiments of integral composite panels and joints for composite structures are described In one implementation, an integrated panel spanning substantially the entire wingspan of an aircraft, includes at least a center portion and a pair of outwardly projecting wing portions. The portions may include a skin formed from successive layers or plies of composite material which overlap and offset at the joint between respective sections creating a pad-up area to carry loads between the portions. In a particular implementation, the skin is laid over one or more structural stringers which are transitioned into the joints between sections such as by tapering of the thickness and/or stiffness of the stringer.Type: GrantFiled: June 13, 2006Date of Patent: November 23, 2010Assignee: The Boeing CompanyInventors: Max U.

Patent number: 7192501Abstract: A method is provided for altering residual stresses in a fiber-metal-laminate structure. At least a first fiber laminate substrate layer having first and second surfaces is provided. At least a first outer metallic laminate layer having third and fourth surfaces is provided, and the first and fourth surface is provided, and the first and fourth surfaces are bonded together. The third surface is peened, such that the at least first fiber laminate substrate layer is subjected to residual tensile stresses and the at least first outer metallic laminate layer is subjected to residual compression stresses. Peening defines a peened region that extends from the third surface into the at least first outer metallic laminate layer a finite distance that is closer to the third surface than the fourth surface.Type: GrantFiled: October 29, 2002Date of Patent: March 20, 2007Assignee: The Boeing CompanyInventors: Willard N.

Patent number: 6114050Abstract: The invention provides a hybrid laminate and skin panels of hybrid laminate structure that are suitable for a supersonic civilian aircraft. The hybrid laminates include layups of layers of titanium alloy foil and composite plies, that are optimally oriented to counteract forces encountered in use, that are bonded to a central core structure, such as titanium alloy honeycomb. The reinforcing fibers of the composite plies are selected from carbon and boron, and the fibers are continuous and parallel oriented within each ply. However, some plies may be oriented at angles to other plies. Nevertheless, in a preferred embodiment of the invention, a substantial majority of, or all of, the fibers of the hybrid laminates are oriented in a common direction. The outer surfaces of the laminates include a layer of titanium foil to protect the underlying composite-containing structure from the environment, and attack by solvents, and the like.Type: GrantFiled: December 29, 1998Date of Patent: September 5, 2000Assignee: The Boeing CompanyInventors: Willard N. Westre, Heather C. Allen-Lilly, Donald J. Ayers, Samuel E. Cregger, David W. Evans, Donald L. Grande, Daniel J. Hoffman, Mark E. Rogalski, Robert J. Rothschilds

Patent number: 4975014Abstract: A high-temperature, low-thermal expansion fastener for joining low thermal expansion refractory materials includes a pin with an inset portion on the shank of the pin that forms a head-facing shoulder, at least one shell insert which is seatable about the inset portion, and an internally threaded member which can be screwed onto the threaded outer surface of the shell inserts to maintain the inserts in abutting relationship with the inset portion. Forces within the fastener are transferred from the internally threaded member to the shell inserts which in turn press against the head-facing shoulder on the pin shank to place the shank in tension. The fastener parts, including a spacer, may be selected to compensate for thermal expansion or contraction of the fastened elements.Type: GrantFiled: September 1, 1989Date of Patent: December 4, 1990Assignee: The Boeing CompanyInventors: Antonio C.

Patent number: 4895378Abstract: A seal for preventing extremely hot gases from passing between a movable engine ramp and an engine splitter wall in a hypersonic aircraft. The seal moves with the engine ramp, in a direction parallel to the surface of the splitter wall. The seal includes a first flange which makes sliding contact with the outer engine ramp surface and is attached to a flexible sealing portion that fills the gap between the ramp and wall. The sealing portion maintains sliding contact with the wall as the gap changes dimension due to variations in the ramp's temperature. The attachment region can be a concave surface to radiate the seal's heat. In a second embodiment, the seal includes a second flange through which the seal is attached to the cooler side of the engine ramp.Type: GrantFiled: June 15, 1988Date of Patent: January 23, 1990Assignee: The Boeing CompanyInventors: Charles W. Newquist, Willard N. Westre, Robert A. Burns, Harry W. Dursch
