Method and System for Mitigating Bowed Rotor Operation of Gas Turbine Engine

Embodiments of systems and methods for operating a gas turbine engine defining a bowed rotor condition are generally provided. The systems and methods include rotating a rotor assembly defining a bowed rotor condition from approximately zero revolutions per minute (RPM) to within a bowed rotor mitigation speed range, in which the bowed rotor mitigation speed range is defined by a lower speed limitgreater than zero RPM and an upper speed limit less than or equal to an idle speed condition of the gas turbine engine; applying a load at the rotor assembly via an energy storage device; adjusting the load to limit rotational speed or acceleration of the rotor assembly to within the bowed rotor mitigation speed range for a period of time; and removing the load to enable rotation of the rotor assembly to the idle speed condition following the period of time. 本发明提供了用于操作限定弯曲转子状况的燃气涡轮发动机的系统和方法的实施例。所述系统和方法包括：将限定弯曲转子状况的转子组合件从大约零转/分钟(RPM)旋转到弯曲转子减缓速度范围内，其中弯曲转子减缓速度范围由大于零RPM的速度下限和小于或等于所述燃气涡轮发动机的怠速状况的速度上限限定；经由能量存储装置在所述转子组合件处施加
