Claims30
A gas turbine engine, comprising:
- a geared architecture with a multiple of intermediate gears;
- and
- a baffle with an oil scavenge scoop adjacent to each of the multiple of intermediate gears.
A geared architecture for a gas turbine engine, comprising:
- a sun gear defined along an axis;
- a ring gear rotationally fixed around the axis;
- a multiple of planet gears in meshed engagement with the sun gear and the ring gear;
- a carrier for rotating about the axis and for rotationally supporting the multiple of planet gears;
- and
- a multiple of baffles mounted to the carrier, each of the baffles includes a multiple of oil nozzles directed toward a gear mesh between one of the multiple of planet gears and the sun gear and an oil scavenge scoop upstream of the multiple of oil nozzles with respect to the gear mesh.
3 more elements
A method of designing a geared architecture for a turbine engine, the method comprising:
- defining a sun gear for rotation about an engine central axis;
- defining a ring gear to be rotationally fixed around the engine central axis;
- defining a multiple of planet gears in meshed engagement with the sun gear and the ring gear;
- configuring a carrier to rotate about the central axis and to rotationally support the multiple of planet gears;
- and
- defining the carrier to include at least one baffle with multiple oil nozzles directed toward a gear mesh engagement between one of the multiple of planet gears and the sun gear, and an oil scavenge scoop upstream of the multiple of oil nozzles relative to the gear mesh.
