Assignee:

General Electric Company - Cincinnati OH

International Classification:

B64D 2700
F02C 720

US Classification:

244 54

Abstract:

An aircraft engine mount includes a frame fixedly joined in a gas turbine engine and a platform fixedly joined to an aircraft wing or tail pylon. A first beam is pivotally joined to the frame and the platform at first and second joints, respectively. The first beam is additionally joined to the platform at a third joint which allows longitudinal movement between the first beam and the platform at the third joint while preventing rotation of the first beam. A second beam is spaced from the first beam and is pivotally joined to the frame and platform at fourth and fifth joints, respectively, and is additionally joined to the platform at a sixth joint for allowing limited rotation of the second beam during normal operation while preventing rotation of the second beam upon a failure of the first beam to carry load.

US Classification:

244 54

Abstract:

An aircraft engine thrust mount includes a pair of spaced apart thrust links pivotally joined at one end to an engine first frame and at opposite ends to a lever. A platform is fixedly joined to an aircraft pylon and includes first and second spaced apart clevises and a center clevis therebetween. The center clevis is pivotally joined to a center of the lever for carrying thrust force from the first frame through both thrust links and to the platform and pylon during normal operation. A pair of pins pivotally join the thrust links to the lever and extend through apertures in the platform first and second clevises to define predetermined gaps therebetween for allowing the lever to rotate relative to the platform center clevis up to a predetermined angular rotation. In a failure mode of operation the pins contact the platform first and second clevises for transmitting thereto either tension or compression thrust loads for providing an alternate failsafe loadpath. In a preferred embodiment, the platform further includes an aft mount joined to an engine second frame spaced aft of the engine first frame.

International Classification:

F04D 2940

US Classification:

415 9

Abstract:

A blade containment system is disclosed which includes an annular casing positioned radially outward of the blades and in surrounding relationship therewith, the annular casing including a plurality of composite tapes bonded to the outer or inner radial surfaces thereof, wherein the composite tapes limit the propagation of cracks and holes formed in the annular casing.

US Classification:

4152092

Abstract:

A structural frame component for use in a gas turbine engine includes an annular outer shell, an annular inner central hub, a plurality of circumferentially-spaced struts extending between the outer shell and central hub, each strut being attached at its inner end to the central hub, and a multi-yoke attachment between the outer ends of the struts and the outer shell. The multi-yoke attachment is composed of a plurality of yokes. Each yoke includes a clevis and a plurality of radially oriented fasteners and tangentially oriented fasteners respectively attaching the clevis between the outer shell and the outer end of a respective one strut.

US Classification:

4152092

Abstract:

A compressor discharge flowpath for a gas turbine engine includes flowpath outer and inner walls joined to a plurality of circumferentially spaced flowpath dividers extending therebetween. An inner support extends from the inner wall and is joined to a turbine nozzle, and an outer support extends from the outer wall and is joined to an engine casing. The outer support preferably includes a plurality of circumferentially spaced beams being sized and configured for carrying both axial force and torque transmitted therethrough from the turbine nozzle to the casing while allowing the beams to bend radially for accommodating differential thermal movement between the casing and the outer wall.

Assignee:

General Electric Company - Cincinnati OH

International Classification:

B64D 2726

US Classification:

244 54

Abstract:

An aircraft engine mounting assembly using a clevis type joint to connect a link is provided with a mounting pin assembly disposed in an aperture of the link having inexpensive and easily replaceable concentric inner and outer non-rotational bushings surrounding a conventional pin and corresponding oppositely disposed sets of inner flat contact surfaces on the outer surface of inner bushing and outer flat contact surfaces on the inner surface of the outer bushing which provide reduced contact stresses between the pin and the aperture as compared to conventional assemblies. The contact surfaces are in general sliding engagement in the longitudinal direction and are provided with clearances between the inner and outer bushings in the longitudinal and transverse directions to allow for thermal growth of the engine.
