Abstract
To address the impact of low-altitude wind shear on aircraft flight safety, this paper establishes a real-time low-altitude headwind shear model based on the vortex ring method and an aircraft dynamic model incorporating disturbance wind parameters. The study investigates the effects of wind shear on aircraft and proposes both longitudinal and lateral escape strategies. In the simulation study, vertical and horizontal wind vector fields of wind shear were first simulated, and wind shear vector diagrams were plotted. Then, using the B747-100 aircraft as the research object, a longitudinal escape numerical simulation was conducted at 80 seconds by setting relevant parameters, followed by a lateral escape simulation at 45 seconds. The results indicate that low-altitude wind shear can lead to a decrease in aircraft airspeed, significant changes in pitch angle, and a reduction in flight altitude, thereby increasing the risk of a crash. Additionally, when encountering wind shear, implementing a longitudinal escape strategy (maintaining a 15° pitch angle and full thrust) can effectively recover flight altitude. The lateral escape strategy also successfully allows the aircraft to escape wind shear. This research provides theoretical foundations and technical support for enhancing aviation flight safety.
