Wind Tunnel for Aerodynamic Research

The following presents in detail one full-scale automobile wind tunnel and two thermodynamic wind tunnels, their development and integration for an economic solution. Information is given on machinery equipment, air speed and temperature ranges and measurement-possibilities.

Two thermodynamic test stands, smaller wind tunnels, are described. The first one is designed for measurements on heat exposed parts of the car, in particular engine cooling. The second one is able to simulate all climatic conditions and was designed for solving problems concerning heating and air conditioning systems.

The presentation concludes with reports on initial experiences with these test facilities.
