Conceptual meaning
Modern aircraft Wheel Braking is very effective, but on wet, icy or snow covered runways Effectiveness May be caused by Aircraft tyre And runway adhesion Loss. Reverse thrust is used to reduce the speed of the aircraft and shorten the taxiing distance after the aircraft touches the ground.
Boeing 777 reverse thrust General Turbofan engine Within duct And external culvert. Air enters these two parts in a certain proportion after entering the engine. In the inner layer is the high-pressure compression section, from which the power of the turbofan engine comes; The second layer is the low-pressure compression section. In the outer layer of the engine, the power of the high-pressure section drives the fan to rotate. The thrust of the aircraft mainly comes from this. [1] After the pilot turns on reverse thrust, cockpit Retrogression of indicator light On, the hydraulic actuator moves the moving sleeve of the thrust reverser cowling backward, with a choke gate to expose the grid section, blocking the path of the fan airflow backward and turning to flow out from the grid section, generating reverse thrust.
