Abstract

The invention discloses a measurement and control system for a miniature wind tunnel, and the system comprises a measurement system and a control system. The measurement system is used for collectingpreset data in a wind tunnel test section in real time, and then transmitting the preset data of the wind tunnel test section to the control system, wherein the preset data includes an atmospheric pressure value, a temperature value and a humidity value in the wind tunnel test section and a miniature differential pressure value at the front and rear ends of the wind tunnel test section. The control system is connected with the measurement system, and is used for receiving the preset data, sent by the measurement system, in the wind tunnel test segment, and then stores and displays the preset data in real time. The measurement and control system can accurately and reliably control the rotation speed of a wind turbine, enables the wind speed stability in the wind tunnel to be good, guarantees the reliable operation of a wind tunnel test, facilitates the popularization and application, and has great practical significance.

Description

technical field [0001] The invention relates to the technical field of wind tunnel tests, in particular to a measurement and control system suitable for small wind tunnels. Background technique [0002] A wind tunnel is a kind of pipe-shaped experimental equipment that simulates the airflow around the aircraft or around the entity by artificially generating and controlling the gas flow rate, and can measure the effect of the airflow on the object and the physical phenomenon accompanying the object. Wind tunnels play a key role in aerodynamic research and the aerodynamic design of aircraft. Many of the key theories of aerodynamics are derived from numerous wind tunnel tests. [0003] In the design of wind tunnel measurement and control system, the two most important tasks are data acquisition and processing and wind speed control. At present, most of the existing wind tunnel measurement and control systems adopt the form of integration of wind tunnel and computer, and the da...
