Turbine shaft engine clutch structure

A gas turbine engine and a method of operating the same are provided. For example, a method of operating a gas turbine engine includes selectively engaging and disengaging an engine clutch disposed between a low speed spool and a rotor assembly of the engine. Engagement or disengagement of an engine clutch is selected based on an operating condition of an aircraft including an engine. Further, an inter-spool clutch disposed between a low-speed spool and a high-speed spool of the engine transitions between engagement and disengagement, disengaged when the high-speed spool reaches a speed greater than an operating speed of the low-speed spool. Similarly, the gas turbine engine includes an engine clutch configured to selectively position the low speed spool in operative communication with the rotor assembly, and an inter-spool clutch configured to position the low speed spool in operative communication with the high speed spool. 提供了燃气涡轮发动机及其操作方法。例如，操作燃气涡轮发动机的方法包括选择性地接合和脱离设置在发动机的低速线轴和转子组件之间的发动机离合器。发动机离合器的接合或脱离基于包
