A method for simulating the flight process of an aircraft

Abstract

The invention provides a method for simulating the flight process of an aircraft and belongs to the field of general aviation for air traffic management. The method for simulating the flight process of the aircraft specifically comprises the steps that the flight process of the aircraft is divided into four stages firstly, wherein the four stages are a departure stage, an airway stage, a marching-in stage and an approaching stage; all passing points of each stage are obtained, an extrapolation algorithm of each passing point is selected to be a direct flight extrapolation algorithm or a turning extrapolation algorithm according to the characteristics of each stage; real-time flight information of the aircraft is obtained once at the position of each passing point of each stage; extrapolation is carried out according to the selected extrapolation algorithm to obtain the flight attitude of the aircraft at each stage according to the flight information; whether the aircraft reaches a passing point is judged each time when the extrapolation is finished, and the extrapolation algorithm is changed if the aircraft reaches a next passing point; the flight attitudes of the aircraft at the four stages are combined to obtain the flight attitudes of the aircraft in the whole flight process. The method is suitable for being used for simulating the whole flight process of the aircraft.

Description

technical field [0001] The invention belongs to the general aviation field of air traffic management, and in particular relates to a method for simulating a flight process. Background technique [0002] When simulating the flight process of an aircraft, the commonly used simulation method at present is mainly the timing extrapolation method. According to a predetermined set of discrete track point positions or real-time instructions from the controller, where the real-time instructions include information such as position, heading and speed, the position of the next point is adjusted every certain time ΔT (such as 1 second, 3 seconds, etc.) Extrapolate to simulate a coherent flight trajectory. [0003] The commonly used extrapolation method is mainly the direct flight algorithm: given the current position L, current speed v, current acceleration a and climb rate l, the flying distance x is obtained, x=v×ΔT+a×ΔT 2 / 2; target speed v'=v+ΔT×a; and target height H, H=L+ΔT×l, a...

AI Technical Summary

Problems solved by technology

The direct flight algorithm is suitable for the situation where the information density of known track points is high and the track is mostly direct flight. For the track with few track points and turning, the direct flight algorithm cannot achieve high-level simulation

[0004] However, the current flight simulator simulates the whole flight process of an aircraft, including the preparation of the departure airport, driving, taxiing, take-off and climb, air cruise flight, landing at the destination airport, cloud penetration, landing, etc., due to many actions and frequent turns , so more track points need to be obtained, and the direct flight algorithm can no longer adapt to the current flight simulator
