Balancing angle adjusting device for horizontal tail

Abstract

The invention relates to a balancing angle adjusting device for a horizontal tail. The balancing angle adjusting device for the horizontal tail comprises a first scale, first uniform scales and a first attachment structure, wherein the first uniform scales are circumferentially arranged on the first scale; the first attachment structure is suitable for being attached to a horizontal tail box section of the horizontal tail; and a second scale, a second uniform scale circumferentially arranged on the second scale, and a second attachment structure adapted to be attached to the elevator of the horizontal tail, and wherein an indexing value of the first uniform scale is not equal to an indexing value of the second uniform scale. The angle adjusting device can adjust a series of deflection angles of the elevator so as to determine the initial attitude of the horizontal tail, thereby researching the stability of the whole structure of the aircraft under the action of dynamic load. The angle adjusting device is simple in structure and easy to operate, facilitates quick reloading of a model test and can quickly and accurately obtain the deflection angle of the elevator, the accuracy of the angle adjusting device can meet the test requirement, and the expected invention purpose is achieved.

Description

technical field [0001] The invention relates to a horizontal tail trim angle adjustment device, which is used in variable-angle model tests of civil aircraft models. Background technique [0002] Some dynamic model tests need to check and adjust the deflection angle of the rudder surface during the test to ensure that the deflection angle is within the range required by the test program. The purpose is mainly to obtain the possible motion characteristics and response of the aircraft. [0003] When designing the dynamic model structure, it is necessary to separately design the adjustable horizontal tail (including the horizontal stabilizer and elevator) according to the test requirements, which can realize the angle adjustment of the movable surface and meet certain error requirements. At present, there are three commonly used methods for measuring the rudder surface angle of aircraft: (1) manual fixture measurement; (2) grating measurement; (3) inclination sensor measurement...

AI Technical Summary

Problems solved by technology

Manually designed fixtures generally have a complex structure, and are limited by the size of the object to be measured, resulting in large measurement errors and low measurement accuracy; grating measurement generally requires calibration of the rudder surface axis in advance, which is troublesome to operate; and inclination sensor measurement requires the installation of sensors and A set of debugging collection feedback system, the cost is relatively high
