Problems solved by technology

The manual adjustment of the wind tunnel flow field has the following disadvantages: the adjustment accuracy of the flow field is easily affected by the pressure fluctuation of the source airflow; the manual adjustment cannot achieve high control accuracy and takes too long, and the energy loss is large
In addition, the structure of the wind tunnel is complex, the control parts are scattered, the types and quantities of ground signals involved are large, and the reliability and real-time performance of signal transmission are high, all of which put forward high requirements for the establishment of a wind tunnel control system

The system comprises a console general control computer, a console analog display computer, a console operation display area, a video monitoring computer, an ethernet switch, a Mach number monitoring computer system, a data acquisition computer system, an equipment management computer system, a diffusion section control computer system, an Ethernet switch, a 2# valve driving unit, an attack angle mechanism driving unit, a safety interlocking PLC unit, a 1# valve and 2# ejector driving unit, a diffusionsection driving unit and a data acquisition unit. According to the invention, a distributed layout is adopted, so that an operator can operate and observe the test condition conveniently, the problemsof scattered control parts, various signal types and large quantity are effectively solved, and the reliability and real-time performance of signal transmission can be well ensured. Ethernet communication is used among the nodes, so that the system nodes are not limited by geographic positions and can be conveniently expanded and moved.

Description

technical field [0001] The invention relates to a temporary subtransonic wind tunnel control system, which belongs to the technical field of subtransonic wind tunnels. Background technique [0002] The wind tunnel is the main equipment for aerodynamic tests. It is a special pipeline designed according to specific requirements. In this special pipeline, the power device is used to generate an adjustable airflow, so that the model flow field obtained in the test section can be simulated or Partial simulation of the prototype flow field. Wind tunnel flow field is a major indicator of wind tunnel performance. In the previous flow field control, the opening of the pressure regulating valve was manually adjusted by the operator to control the flow of compressed air entering the wind tunnel. The manual adjustment of the wind tunnel flow field has the following disadvantages: the adjustment accuracy of the flow field is easily affected by the pressure fluctuation of the source air...
