Embodiment Construction
[0051] The present invention will be described in further detail and completely below in conjunction with the embodiments and accompanying drawings.
[0052] Basic knowledge introduction:
[0053] Thrust-to-weight ratio: Thrust-to-weight ratio is an important technical performance index of aircraft and aeroengines. It is the ratio of aircraft engine thrust to engine gravity or aircraft gravity, which indicates the thrust generated by aircraft engine or aircraft unit gravity. The ratio of the thrust produced by an aircraft engine at its maximum state (the afterburner engine is in the full afterburner state) to the weight of the engine structure under static conditions at sea level is called the thrust-to-weight ratio of the aircraft engine.
[0054] Stall Landing: A stall is a condition in which an aircraft or wing operates at an angle of attack greater than the maximum lift angle of attack, and is characterized by separation of the airflow, making it impossible to maintain fli...
