GTI Calibration Wind Tunnel Model T521A

Introduction

The Open Return Steady low-speed flow Calibration Wind Tunnel Model T521A is mainly used for metrological traceability of Thermal Anemometers and Pitot tubes. It provides verification, testing and calibration for the R&D, production and application of wind speed measuring instruments, as well as for miniature weather stations.

Principle

A Wind Tunnel is a piece of basic equipment for aerodynamic experiments.  The so-called wind tunnel refers to the equipment that is driven by a power device in a pipeline system designed according to certain requirements to form a controllable airfiow, and various aerodynamic experiments are carried out according to the principle of relativity and similarity of motion.

Features

Calibration Wind Tunnel Model T521A is a low-speed airflow generation device capable of stably producing continuously adjustable and uniform airflow. It adopts touchscreen operation for precise parameter control, and features a user-friendly human-machine interface for convenient operation.

Composition

• Inlet section: the inlet through which external air enters the cavity. The embedded honeycomb straightens the incoming airflow.

• Contraction section: Accelerate the airflow velocity to the wind speed value required for the test section.

• Test section: The area where the wind field quality meets the test requirements is also the area where the test operation is carried out.

•  Diffuser section: part of the kinetic energy of the airflow is converted into pressure energy, with low pressure loss and wind field noise, so that the energy consumption and noise indicators of the wind tunnel meet the use requirements. The diffuser section also plays a role in the transition between the test section and the fan section.

• Fan section: Provides power for the operation of the wind tunnel. It has a built-in axial flow fan to provide a power source for the wind tunnel by controlling the speed of the fan.

• Outlet diffuser section: further convert part of the kinetic energy of the airflow into pressure energy, reduce pressure loss and wind field noise, and make the energy consumption and noise indicators of the wind tunnel meet the use requirements.

• Axial fan guard: blocks large foreign objects and ensures safety.

• Electrical control box: The electrical components of the wind tunnel are installed in the electrical control box to ensure safe use and beautiful appearance.

• Operation panel: control the start and stop of the fan and adjust the fan speed. The speed of the fan can be monitored on the screen, and the equipment is equipped with an anemometer to monitor the wind speed value.
