• How do wind tunnels work and how are they used? - Garber ...

    Aug 16, 2016  Wind tunnels have a high-powered fan on both ends of the tube. One to blow wind onto the object and another to move air out of the tunnel. That way there is no return flow that could damage the data being collected. Wind tunnels can be a small as a coffee table or as large as a warehouse.

    In essence, a wind tunnel is a massive tube with fans that produce airflow over an object inside. This can be a car, an airplane, or anything else that engineers need to measure for air resistance. From a room behind the tunnel, engineers study the way the air interacts with the object, the way the air currents flow over the various surfaces.

    A vertical wind tunnel (VWT) is a wind tunnel which moves air up in a vertical column. Unlike standard wind tunnels which have test sections that are oriented horizontally, as experienced in level flight, a vertical orientation enables gravity to be countered by drag instead of lift, as experienced in an aircraft spin or by a skydiver at terminal velocity.
