Embodiment 2

[0026] There are three methods for the deflection control commands of the left and right side bars:

[0027] (1) The stepped deflection control command can realize the stepwise change of the pitch angle of the side strip wing / canard wing, that is, the static adjustment of the pitch angle angle, which is used for static tests;

[0028] (2) Uniform speed motion control command, which can adjust the displacement and speed of the movement, and can realize the uniform speed change of the pitch angle of the wing / canard, which can be used in the dynamic deflection test to test the dynamic effect of the deflection of the side strip, that is, to dynamically adjust the pitch In addition, the beneficial interference of the aerodynamic vortex system of the side wing / canard wing and the aerodynamic vortex system of the main wing can be obtained, thereby realizing active flow control or equivalent to the role of the rudder surface, and improving the aerodynamic characteristics of the aircraf...

Abstract

The invention discloses a controllable strake wing/canard wing pitching angle movement system of an airplane wind tunnel test model. The controllable strake wing/canard wing pitching angle movement system comprises a headpiece and frame component, an airplane model shafting vertical axis, left and right connecting shafts, left and right strake wings/canard wings as well as rotary shafts thereof, left and right bearings, left and right bearing seats, left and right reversing bevel gear pairs, left and right motor installation bases, left and right motors and a coder, left and right main wings, a computer and left and right motor drivers, wherein the right strake wing/canard wing is fixed with the right strake wing/canard wing rotary shaft, the right strake wing/canard wing rotary shaft is connected with the right end of the right connecting shaft, the left end of the right connecting shaft is connected with lower gears of the right reversing bevel gear pair, the same connecting mode is adopted at the left side; the left strake wing/canard wing rotary shaft axis and the right strake wing/canard wing rotary shaft axis are symmetrically arranged along longitudinal symmetrical surfaces of the airplane model shafting vertical axis. The controllable strake wing/canard wing pitching angle movement system can be used for realizing controllable yaw motion of the strake wing/canard wing pitching angle, and changing the mode of regulating the strake wing/canard wing pitching angle through a fixed angle plate in a static mode in the conventional wind tunnel test.

Description

technical field [0001] The invention relates to an aircraft wind tunnel test model side strip wing / canard wing pitch angle controllable motion system. Background technique [0002] In traditional aircraft design, the slat wing is a fixed component that is relatively fixed to the aircraft. In the layout selection, in order to determine the relative relationship between the slat wing and the aircraft, some fixed angle pieces are designed in the wind tunnel test simulation , used to fix and connect the wing and the aircraft model, but these corner pieces can only achieve the angle of the existing design, and cannot be continuously adjusted or dynamically changed. [0003] In traditional aircraft design, the canard is a control surface. In the wind tunnel test simulation, some fixed angle pieces are designed to fix and connect the canard and the aircraft model. These angle pieces can only realize the angle of the existing design, and cannot be continuously adjusted or dynamical...
