Embodiment Construction

[0023] In order to make the purpose, technical solution and advantages of the application more clear, the technical solution in the embodiment of the application will be described in more detail below in conjunction with the drawings in the embodiment of the application.

[0024] Such as figure 1 As shown, the application provides a method for processing pilot control device flight test data, and the method specifically includes:

[0025] S1. Selection of effective data

[0026] Firstly, the flight test data of the driver's control device is obtained, and for a single flight test data, noise interference is firstly eliminated, non-driver conscious control points are eliminated, and valid data points are retained. Such as figure 2 As shown, first calculate the difference between the initial data point a and the next data point b, namely |y a -y b |Compared with the threshold △, if |y a -y b |a -y b |>threshold △, then the data point b is a valid data point, continue to ...

Abstract

The invention provides a driver control device test flight data processing method, which comprises the following steps: acquiring test flight data of a driver control device, and screening the test flight data to obtain effective data of the test flight data; all extreme points are selected from the effective data; determining the number of motion cycles of a driver operating device in unit flight time according to the extreme point, wherein the number of motion cycles is half of the number of extreme points; determining the motion frequency in a preset range according to the percentage of the stroke difference value between every two extreme points and the total stroke; the multiple groups of test flight data are processed to calculate the total use frequency of a driver operating the device at a single time and the proportion of each section of travel; according to the processing results of the multiple groups of test flight data, the maximum value of the maximum use frequency and the stroke ratio of the driver control device is obtained, and the product of the maximum value and the safety coefficient serves as the design basis and the life test assessment index of each component of the driver control device.

Description

technical field [0001] The application belongs to the technical field of flight data processing, and in particular relates to a method for processing flight test data of a pilot control device. Background technique [0002] The main function of the pilot's control device is to convert the pilot's manipulation behavior on the control stick, pedals, etc. into electrical signals, and transmit them to the flight control computer. After calculation by the flight control computer, a signal to control the deflection of the rudder surface is formed. [0003] The pilot control device is an important device that affects the safety of the aircraft. Knowing the frequency of use of the pilot control device and its stroke distribution during the actual flight is an important basis for the design of the components of the pilot control device. The life test assessment index of each component component. Contents of the invention [0004] The purpose of this application is to provide a met...
