How To Build A Wind Tunnel. This is a closed loop wind tunnel subsonicWatch part 2 for the experiments. Form a column using the wire making sure it is the same size as the circumference of the fan. Building a Wind Tube For our new Family Inventors Lab class we have built a fun toolwhich encourages the kids to tinker - see my last post for how kids play with a wind tube. Run a line of hot glue along all of the inside edges of the section d.
Here is a wind tunnel design that was developed at NASA Glenn during the Centennial of Flight Celebration in 2003. Connect Toggle switch battery connector and Motor wires together to form a circuit which shall make motor ON OFF. I made a wind tunnel. Taking into account all the recommended values for the secondary design parameters a guess value for the wind tunnel overall length with a contraction ratio N9 high quality flow is given by the formula. Cut all pieces to size see attached drawings b. Tape the ends together twist the wire together or do both.
Aviation High School Wind Tunnel.
Pull the strip tight from both ends. The wind tunnel you will build is not a closed-circuit wind tunnel because this would be very expensive and difficult to make without sophisticated equipment and materials. Instead you will be making an open-circuit tunnel which is more like a tube that is open at both ends see Figure D. 2 Cut a strip of craft paper 4 wide and 24 long. This can be tested by placing small paper inside bottle when fan is rotating. Make sure fan is rotating in such a way that it pulls air from neck of the bottle.
