Abstract

The invention relates to a method for predicting and warning aircraft wake threat areas. By arranging two laser radars at the airport, the first laser radar is arranged on one side of the runway for measuring the glideslope wind field, which is used as an aircraft wake vortex intensity circulation prediction model and The important input parameters of the wake vortex core trajectory prediction model. The second laser radar is arranged outside the runway and below the glideslope to obtain the actual wake vortex intensity circulation and the actual wake vortex when the aircraft flies over the intersection of the second laser radar and the glideslope. The position of the vortex core is used to calibrate the prediction model, so as to accurately predict the dissipation and movement of the wake vortex, identify the potential risk of the wake vortex encounter, and remind and display it on the air traffic control automation system, so that the controller can take early action Response measures to resolve air traffic safety hazards and ensure flight safety.

Description

technical field [0001] The invention relates to the field of civil aviation radar safety management, in particular to a method for predicting and warning aircraft wake threat areas. Background technique [0002] Wake turbulence is the accompaniment of the aircraft when it generates lift, and it is one of the important threats to the flight safety of the following aircraft. When the rear aircraft enters the wake vortex flow field formed by the front aircraft, under the action of the induced downwash velocity, dangerous situations affecting flight safety such as tilt, roll, stall, and sharp pitch may occur. With the continuous and rapid growth of air traffic volume, as well as the improvement of communication, navigation, and surveillance technology and performance, the air traffic control interval is continuously reduced, and the air traffic density in terminal control airspace is increasing. The resulting wake encounter risks and Security control pressure is also increasing...
