This is a design for an open ended wind tunnel. This means the fan pushes air into the tunnel instead of pulling it out the end. Assembled it is 4ft long, 2 feet wide, and 2 feet high. Our hope in building this tunnel as we did was that in future it would require no tools to re-assemble. This design is a larger version of a tunnel original built by Louis Cheng at CSS using an old computer fan.
How it works in the classroom:
The challenge to students is two fold. They will design and
build a wing/air foil that will generate the most lift in the wind tunnel and
achieve the greatest distance outside the wind tunnel.
