Patent number: 8821124Abstract: A hybrid airfoil for a gas turbine engine is provided that includes a body and a panel. The body has a first side and a second side orientated opposite the first side. The first and second sides extend between a tip, a base, a leading edge and a trailing edge. The body includes a plurality of cavities disposed in the first side of the body, which cavities extend inwardly toward the second side. The cavities collectively form an opening. At least one rib is disposed between the cavities. A shelf is disposed around the opening. The panel is attached to the shelf first mounting surface and to the rib, and is sized to enclose the opening.

Patent number: 5015116Abstract: A dimensionally stable structural joint particularly suited for use in space systems. The joint comprises a connector having at least two tubular sleeves, at least two tubular members, and at least two annular clamping means for securing the tubular members inside the connector. The connector comprises at least two elements, manufactured from a fiber reinforced composite, which, when mated, form the connector. The tubular members are manufactured from a material having a coefficient of axial expansion of substantially zero. The annular clamping means are manufactured from a material having substantially the same coefficient of radial expansion as the tubular members. The combination of the connector comprises at least two elements and the annular clamping means with substantially the same coefficient of radial expansion as the tubular members allows the joint to accommodate radial expansion and contraction while maintaining axial dimensional stability.Type: GrantFiled: February 26, 1990Date of Patent: May 14, 1991Assignee: United Technologies CorporationInventors: Vincent C.
