SMALL SCALE CLOSED LOOP WIND TUNNEL FOR TESTING MODEL CARS

CLOSED LOOP SMALL SCALE WIND TUNNEL

THE SCIENCE OF MEASUREMENT

The designer of BE1, 2 & 3 built a series of small wind tunnels to refine the aerodynamics of his vehicles. The tunnel shown above was the latest. It could accommodate 1/25th scale models. Strain gauges provided measurement of drag, lift and downforce. A rotating table was incorporated. Air temperature and wind speed were also monitored and smoke could be trailed over models to visualize airflow. This tunnel could fit comfortably on an office desk. Being a closed circuit design it was not too noisy in operation.

WIND TUNNEL MODEL MAKING STAGES

Step 2. Assemble plywood formers

Step 3. Fill formers with foam and shape

Step 4. Coat foam plug with plaster

Step 5. Sand, add detail mouldings and prime

Step 6. Paint finished model

This is the kind of result you can expect from your wind tunnel - a super slippery 350+ mph electric streamliner. This particular car is charged by solar power, making it probably the world's fastest solar powered electric land speed record car. She also has battery cartridge exchange built in, for instant refueling.
