Method for determining airplane critical circumvention parameters in low-altitude wind shear

Abstract

The invention belongs to the design field of flight safety, and relates to a method for determining airplane critical circumvention parameters in low-altitude wind shear. The method is characterized in that the method for circumventing the low-altitude wind shear in a critical mode for an airplane includes the following steps that a circumvention turning radius R is calculated; a normal direction overload coefficient nz is calculated; turning time t of the airplane is calculated; airplane turning angular speed omega and airplane gradient phi are calculated; minimum flight safety height Hs of the airplane is calculated. The method for determining the airplane critical circumvention parameters in the low-altitude wind shear substantially reduces workloads, and improves working efficiency.

Description

technical field [0001] The invention belongs to the field of flight safety design and relates to a method for determining critical avoidance parameters of an aircraft in low-altitude wind shear. Background technique [0002] The determination of the critical trajectory of the aircraft to avoid wind shear can ensure the safe flight of the aircraft. If it directly penetrates or partially penetrates the wind shear, it may cause flight hazards, so the determination of the critical trajectory to avoid is particularly important. figure 1 is a schematic diagram of an aircraft avoiding a windshear area. ( figure 1 D is the scale of wind shear; the small circle with scale D represents the wind shear area; L is the radar detection distance of the aircraft; AB section is the critical avoidance trajectory; R is the avoidance radius; R+D / 2 represents the center of the wind shear area Distance to the center of the avoidance trajectory. ) At present, for the problem of wind shear avoida...

Its disadvantages are: heavy workload, long working hours and low efficiency

However, the above method must go through multiple simulations to obtain the critical avoidance parameters. It also has the disadvantages of heavy workload, long working hours and low efficiency.
