Wind tunnels (WT) with an open loop circuit are a fundamental tool in experimental aerodynamics. Their design allows the direct flow of air drawn from the surroundings through the measuring section, eliminating the need for a return path for the air back to the fan. Due to this configuration, they are not only simpler but usually also a more economical choice for a wide range of aerodynamic tests.

Although open circuit WTs require higher power than closed WTs, they balance this with other advantages. The test section can be configured as either open or closed according to the specific testing needs. Moreover, despite their open circuit design, they minimize turbulence in the test airflow and provide stable airflow, which is crucial for measurement accuracy.

Due to their affordability, they are an ideal choice for universities and smaller laboratories seeking an efficient solution without the need to invest in more expensive closed circuit WTs.

WTtech.CZ will design, manufacture and deliver WTs tailored to your requirements. From customized dimensions of the test section to demands on the quality and speed of airflow, as well as adapting to the laboratory‘s spatial constraints and available power input, you will receive a tool that matches not only your research objectives but also specific applications and available resources.
