Four-dimensional flight path prediction method based on control intention and aircraft performance model

Abstract

The invention discloses a four-dimensional flight path prediction method based on a control intention and an aircraft performance model. When the flight does not fly, initial planning information is utilized to establish an aircraft dynamic model by combining empirical data which is obtained by historical data mining and reflects the control intention, such as the empirical height of the flight passing through each report point, a four-dimensional flight path point sequence to be generated by the flight is predicted in advance by considering meteorological conditions, and a flight 4D prediction result is dynamically corrected after the monitoring data is received. The flight 4D trajectory prediction precision is improved, flight conflict detection and flow management decision making can becarried out in advance, and the air traffic pressure is relieved.

Description

technical field [0001] The invention belongs to the technical field of aircraft four-dimensional (4D) track prediction in air traffic management systems, and specifically refers to a four-dimensional track prediction method based on control intentions and aircraft performance models. Background technique [0002] As an important industry and an advanced mode of transportation for the development of my country's national economy and society, the civil air transportation industry has also developed rapidly along with the continuous development of the entire national economy. By 2017, the total number of civil aviation airports in China had increased from 94 in 1990 to 216, and the total number of routes was nearly 4,000. There are more and more aircraft on the flight route, and the flight distance is getting smaller and smaller, and the air traffic safety situation is becoming more and more severe; problems such as flight delays and airspace congestion also occur frequently. ...

Problems solved by technology

[0010] Aiming at the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide a four-dimensional trajectory prediction method based on control intentions and aircraft performance models to solve the problems of continuous growth of air traffic volume, urgent need to improve regional traffic efficiency, and flight trajectory prediction method. Problems such as low prediction accuracy; the present invention makes full use of the superiority of the aircraft performance model, and considers obtaining the empirical parameters (report point passing point altitude) reflecting the actual control intention from the historical track data, effectively coupling the two, and combining Meteorological high-altitude wind data, comprehensively improve the accuracy of 4D track prediction while ensuring calculation efficiency
