Embodiment 1

[0088] As a basic embodiment of the present invention, the present invention includes a calibration assistance method for installation of aircraft avionics equipment, comprising the following steps:

[0089] a. Install the calibration fixture.

[0090] b. Observe the position of the center of the reticle in the collimating telescope on the target circle, and read the pitch angle ω and roll angle λ; the pitch angle is the normal vector of the plane where the base of the avionics equipment is located on the YOZ plane under the aircraft coordinates The angle ω between the projection and the Z axis; the roll angle is the angle λ between the projection of the XOZ plane and the Z axis of the normal vector of the plane where the base of the avionics equipment is located in the aircraft coordinates.

[0091] c. Calculate the simulated pose coordinates of the adjustment point by solving the simulated pose coordinates of the avionics equipment based on the pitch angle and roll angle.

Embodiment 2

[0095] As the best implementation mode of the present invention, the present invention includes a calibration assistance method for installation of aircraft avionics equipment. figure 1 , including the following steps:

[0096] a. Install the calibration fixture.

[0097] b. Read the pitch angle ω and roll angle λ.

[0098] c. Calculate the simulated pose coordinates of the adjustment point by solving the simulated pose coordinates of the avionics equipment based on the pitch angle and roll angle. details as follows:

[0099] c 1 . Refer to the attached figure 2 with instructions attached image 3 , connect the three adjustment points A, B and C on the installation base to determine the plane ABC, (where: point A is not necessarily on the plane XOY; since the yaw angle has been calibrated, point C is on the YOZ plane at this time within, but not necessarily on the Y axis). The normal vector to the plane ABC according to the pitch angle ω and roll angle λ Solve to desc...

Abstract

The invention relates to the technical field of aircraft assembly, in particular to a calibration auxiliary method for the installation of aircraft avionics equipment, which calculates the simulated pose coordinates of the adjustment points by calculating the simulated pose coordinates of the avionics equipment based on the pitch angle and roll angle ; Through pose adjustment and optimization, the optimal scheme of gasket specification selection at the adjustment point is solved; finally, the gasket is adjusted according to the optimal scheme. Through the method, the problems of low efficiency, high labor intensity and large human error can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of aircraft assembly, in particular to a calibration auxiliary method for installing aircraft avionics equipment. Background technique [0002] The installation and attitude calibration of aircraft avionics equipment is crucial to its effectiveness. The current installation pose calibration work is usually carried out by the method of measuring and adjusting multiple rounds of repetition and successive iterations. Each iteration needs to install the calibration tooling first, then observe the position of the center of the reticle in the collimating telescope on the target circle, then analyze and calculate the deflection angle of the avionics equipment, then disassemble the tooling, adjust the gasket, and finally install the tooling and observe The position of the center of the reticle on the target circle in a straight telescope. [0003] Its main work contents include: [0004] (1) Yaw angle calibration...
