Zusammenfassung: | The invention belongs to the field of aero-engine design, and relates to a method for supplying oil to a thrust augmentation outer area when a shipboard aircraft engine encounters temperature distortion during takeoff, which comprises the following steps of: after judging that the engine encounters temperature distortion, starting a thrust augmentation outer area oil supply rule; an outer zone fuel flow correction coefficient related to the rear total pressure of the high-pressure compressor, outer zone fuel flows at different temperatures related to the inlet temperature and a throttle lever angle correction coefficient and outer zone fuel flow correction coefficients at different rear total pressures of the high-pressure compressor are calculated respectively; and when the temperature distortion exits, if the difference between the new rule and the outer area fuel flow under the original rule is large, the outer area fuel flow is transited from large to small in sequence through a transition algorithm, and |
