A method enables a nozzle support for a gas turbine engine to be fabricated. The method comprises forming an annular assembly including a plurality of circumferentially-spaced gas injector assemblies, wherein each gas injector assembly includes a plenum and a unitarily formed injector that extends outwardly from an outer surface of the plenum, and forming a passageway through the injector such that the passageway extends between an inlet and an outlet, and is obliquely aligned with respect to the plenum exterior surface.

Methods and apparatus for injecting fluids in gas turbine engines

A fail-safe lug is carried by an engine frame member and receives a clevis carried by an engine mount member. The mount member includes side links that transmit transverse loads between the engines and the airframe and a thrust link that transmits axial, engine thrust loads between the engine and the airframe. A fail-safe pin is carried by the clevis and has an outer diameter that is smaller than an aperture in the lug and through which the pin passes, so that no loads are imposed on the fail-safe pin in normal operation. When one or more of the links are no longer capable of transmitting loads, the fail-safe arrangement becomes operative to accommodate the loads transmitted between the engine and the airframe.

Fail-safe aircraft engine mounting system

A mount for mounting an aircraft engine to an aircraft includes a mounting frame having first and second flanges spaced apart a predetermined distance. Each of the first and second flanges has a bolt hole formed therein. A single thrust link is connected at one end to the mounting frame and at another end to the engine and serves as the primary axial loadpath for the engine. A lug formed on the engine casing is disposed between the first and second flanges and has a thickness that is less than the distance between the first and second flanges. The lug also has a bolt hole formed therein. A bolt extends through the bolt holes in the first and second flanges and the lug to connect the lug to the first and second flanges. The bolt hole in the lug is larger in diameter than the bolt to allow the lug to slide axially along the bolt. The first and second flanges, the lug and the bolt provide a waiting failsafe arrangement for reacting axial loads upon failure of the single thrust link.

Aircraft engine mount with single thrust link

A system for mounting an aircraft engine to an aircraft includes four forward mounting features, two mid mounting features, and four aft mounting features disposed on the engine. The forward, mid and the aft mounting features, respectively, are equally spaced circumferentially about the engine. The method of mounting the engine includes connecting the first and fourth forward mounting features to mounting structure, the first and fourth aft mounting features to mounting structure, and the first and second mid mounting features to mounting structure when the aircraft engine is used in a top mounted installation. Alternatively, the first and second forward mounting features, the first and second aft mounting features, and the first mid mounting feature are connected to mounting structure when the aircraft engine is used in a first side mounted installation; or the third and fourth forward mounting features, the third and fourth aft mounting features, and the second mid mounting feature are connected to mounting structure when the aircraft engine is used in a second side mounted installation. Another arrangement includes connecting the second and third forward mounting features, the second and third aft mounting features, and the first and second mid mounting features to mounting structure when the aircraft engine is used in a bottom mounted installation.

System for mounting aircraft engines

An aircraft engine mount for mounting an engine to an aircraft includes a mounting frame fixedly joined to the aircraft, first and second prime links and a waiting failsafe link. The first prime link is joined to the engine at a first joint and to the mounting frame at second and third joints. The second prime link is joined to the engine at a fourth joint and to the mounting frame at fifth and sixth joints. The waiting failsafe link is joined to the engine at a seventh joint and to the mounting frame at an eighth joint. The first, third, fourth, sixth and seventh joints are ball joints, and the second and eighth joints are translating ball joints. The fifth joint is a clearance pin joint. All of the translating ball joints include a spherical bearing disposed in an opening in the respective link and a pin extending through the spherical bearing. An inner bushing is disposed on the pin and an outer bushing disposed over the inner bushing. The inner bushing has an oppositely disposed set of planar surfaces formed on its outside diameter, and the outer bushing has an oppositely disposed set of axially extending planar surfaces formed on its inside diameter. Each one of the set of planar surfaces formed on the outer bushing slidingly engages a corresponding one of the set of planar surfaces formed on the inner bushing.

Aircraft engine mount

A link for use in an aircraft engine mounting system includes a span section having a first connector formed (at one end thereof and a second connector formed at another end thereof. A lumped mass is disposed on the span section for placing the resonant frequency of the link away from engine excitation frequencies.

Link component for aircraft engine mounting systems

A thrust mount includes a platform mountable to an aircraft pylon, and includes end clevises and a center clevis therebetween. An equalizer lever includes opposite ends, and a center therebetween pivotally joined to the center clevis. Thrust links are pivotally joined to the lever ends. And, a pair of elastomeric snubbers are disposed adjacent respective ends of the lever inside the end clevises in frictional abutment therebetween.
