Abstract
A gas turbine engine includes an engine static structure. A rotating structure is configured to rotate relative to the engine static structure. The rotating structure has a target area with first and second directions. The first direction is greater than the second direction. A lubrication system includes a nozzle having a non-circular exit aimed at the target area. The exit provides a width and a height. The width is greater than the height. The width is oriented in the first direction.
Claims12
A gas turbine engine comprising:
- an engine static structure;
- a rotating structure configured to rotate relative to the engine static structure, the rotating structure having a target area defined by first and second dimensions respectively arranged in first and second directions, the first dimension greater than the second dimension;
- and
- a lubrication system including a nozzle having a non-circular exit aimed at the target area, the exit providing a width and a height, the width greater than the height, and the width oriented in the first direction, the exit configured to spray a lubricant directly onto the target area, wherein the target area is a window providing an opening in the rotating structure to flow oil underneath a bearing supporting the rotating structure for rotation relative to the engine static structure.

- an engine static structure;
- a rotating structure configured to rotate relative to the engine static structure, the rotating structure having a target area defined by first and second dimensions respectively arranged in first and second directions, the first dimension greater than the second dimension, wherein the rotating structure includes a shaft, and a bearing supports the shaft for rotation relative to the engine static structure, wherein a nozzle is arranged in a compartment with the bearing, wherein the rotating structure includes a spacer abutting the bearing, the spacer provides the target area;
- and
- a lubrication system including the nozzle, the nozzle having a non-circular exit aimed at the target area, the exit providing a width and a height, the width greater than the height, and the width oriented in the first direction, the exit configured to spray a lubricant directly onto the target area, wherein the target area is a window providing an opening in the spacer to flow oil underneath the bearing.
