Airspeed Static Pressure Ring Modification for Educational Wind Tunnel

Intended for use with the EDU Wind Tunnel Github Repository to add Arduino based airspeed measurement and control to your Modular STEM Wind Tunnel project. See the GitHub repo for full documentation and details of use.

Files include:

1. Original Test Section modified to add four pressure tap holes where 1/16" OD tubing can be inserted.

2. Short straight section with four pressure tap holes where 1/16" OD tubing can be inserted. This should be installed just upstream (before) the test section. Use this if you don't want to re-print the entire test section to add airspeed capability.

3. Static Pressure Manifold: Connect four 1/16in soft line tubes together to a single 1/8in soft line tube. For use in combining the pressure from the four sides of the test section into the transducer.

4. A simple block with mounting holes for the Barometer and Airspeed sensor.

If you find this useful an you want to support my time in making and maintaining it, buy me a coffee (or mead). 

Addition of 1/16 inch or 0.063in pressure tap ports to the test section and a pre-test section straight duct for the purpose of measuring airspeed.
