Abstract
A method for mounting a gas turbine engine having a compressor section, a combustor section, a turbine section, a pylon and a rear mount bracket, includes positioning the mounting bracket between the gas turbine engine and the pylon. The mounting bracket is connected to the turbine case reacting a least a vertical load, a side load, a thrust load, and a torque load from the gas turbine engine through the mounting bracket. The mounting bracket is attached to the pylon reacting the same loads from the gas turbine engine.
Claims15
A method of mounting a gas turbine engine having an engine axis to a pylon comprises:
- positioning a mounting device between the engine and the pylon, the mounting device comprising a saddle-shaped yoke, a stanchion, and a bracket connected to the yoke by the stanchion, wherein the stanchion comprises:
- a distal cylindrical section adjacent the yoke;
- a proximal cylindrical section adjacent the bracket, and of smaller radius than the distal cylindrical section;
- and
- a conical section connecting the proximal cylindrical section and the distal cylindrical section;
- positioning the yoke around the engine;
- attaching a first leg of the yoke to a first location on the engine with a first fastener;
- attaching a second leg of the yoke to a second location on the engine with a second fastener, wherein the second location is opposite the first location across the engine axis;
- and
- attaching the bracket to the pylon with a single axial pin, the bracket of the mounting device comprising a single spherical bearing such that the mounting device can rotate with respect to the pylon about an axis that is perpendicular to the engine axis.
A method of mounting a gas turbine engine having an engine axis to a pylon comprises:
- positioning a mounting device between the engine and the pylon, the mounting device comprising a saddle-shaped yoke, a stanchion, and a D-shaped bracket connected to the yoke by the stanchion;
- positioning the yoke around the engine;
- attaching a first leg of the yoke to a first location on the engine with a first fastener;
- attaching a second leg of the yoke to a second location on the engine with a second fastener, wherein the second location is opposite the first location across the engine axis;
- and
- attaching the D-shaped bracket to the pylon with a single axial pin, the D-shaped bracket of the mounting device comprising a single spherical bearing such that the mounting device can rotate with respect to the pylon about an axis that is perpendicular to the engine axis.
A method of transmitting loads on a gas turbine engine comprising:
- attaching a D-shaped bracket end of a mount to a pylon via a single pin and a spherical bearing;
- and
- connecting the engine to the mount via a semicircular yoke;
- wherein the mount reacts at least a vertical load, a side load, a thrust load, and a torque load from an engine.
