在发动机的日常维护和使用中,我们经常接触到几个有关起飞推力的概念:最大额定推力起飞、减额定推力起飞、减推力起飞、灵活推力起飞。使用不同的推力起飞,不但关系到发动机的使用寿命、可靠性、维护和运营成本;而且在某些特殊机场,也有环保减噪方面的要求。 减额定推力起飞是使发动机的起飞功率低于最大值。如果飞机选装有减额定推力起飞功能,则FADEC(全功能数字发动机控制)装置可以调定一个减额定等
In the routine maintenance and use of the engine, we often come across several concepts related to take-off thrust: the maximum rated thrust takeoff, thrust reduction takeoff, thrust takeoff, and flexible thrust takeoff. The use of different thrust off, not only related to the life of the engine, reliability, maintenance and operation costs; and in some special airports, there are environmental noise reduction requirements. De-rated thrust take-off is to take off the power of the engine below the maximum. If the aircraft is equipped with a reduced thrust takeoff function, the FADEC (full featured digital engine control) unit can be set to a reduced rating
