Abstract

The invention discloses a synchronous control system and method for an all flexible plate nozzle of a wind tunnel. The synchronous control system comprises a left wall plate, a right wall plate, flexible plates, a front end plate, a rear end plate and drive mechanisms, wherein the left wall plate and the right wall plate are arranged in parallel in the horizontal direction; the two flexible plates are arranged symmetrically in the longitudinal direction and form a column body with the left wall plate and the right wall plate, and the side surfaces of the column body are sealed; multiple hinge supporting points are arranged on the surfaces, backing to airflow, of the flexible plates, and the flexible plates are connected with the drive mechanisms through the hinge supporting points; the front end plate and the rear end plate are vertically arranged at two ends of the column body. The structure with a round outside and a square inside is formed, airflow of the wind tunnel goes in from one end of the column body and goes out from the other end of the column body, and the front end plate and the rear end plate can be used for fixing and mounting the flexible plates.

Description

technical field [0001] The invention relates to the field of subsonic test wind tunnels, relates to a Mach digital digital control system and a control method, in particular to a synchronous control system and a control method for fully flexible-wall nozzles. Background technique [0002] A wind tunnel is a pipe-shaped experimental device that artificially generates and controls airflow to simulate the flow of air around an aircraft or object, and can measure the effect of airflow on an object and observe physical phenomena. The structure of the wind tunnel is generally It can be divided into functional sections such as stable section, contraction section, test section, diffusion section, and fan section. Traditional wind tunnels mostly use solid block nozzles and semi-flexible nozzles in the contraction section. The solid block nozzle needs to be replaced with different solid blocks during different Mach number tests. The flexible wall shaft of the semi-flexible wall nozzle...
