Build an Inexpensive Wind Tunnel to Test CO2 Cars

As part of the technology education curriculum, the author's eighth-grade students design, build, test, and race CO2 vehicles. To help them in refining their designs, they use a wind tunnel to test for aerodynamic drag. In this article, the author describes how to build a wind tunnel using inexpensive, readily available materials. (Contains 1 figure.)

Measuring Drag Coefficient in a Wind Tunnel

13/05/2021  Barberton High School has a subsonic open circuit wind tunnel. The wind tunnel was deigned by NASA wind tunnel experts and built by high school students. A project was planned that involved three ninth grade sciences to design and manufacture small dragster cars to be tested in the wind tunnel

CO2 Dragster Project

For this project, we were required to build a successful and fast Co2 dragster car. First, we had to understand what a Co2 car was and how it works. CO 2 dragsters are miniature racing cars which are propelled by a carbon dioxide cartridge, pierced to start at the release of the gas. They typically race on a track against each other, and want to be the fastest car. They are frequently used to ...

About this site

Wind tunnels are a fun way for students to explore physics concepts surrounding flight, air resistance, drag and aerodynamics. By rapidly creating and testing designs for objects that sink, float, or hover in a wind stream, students get immediate feedback on ideas, allowing for rapid refinements, confidence trying new concepts and explorations of problems in an engaging way.

Building and Testing a Wind Tunnel - Menlo School

A wind tunnel has been built to measure drag and downforce of 1:18 scale model cars. The wind tunnel is composed of a contraction cone, test section, and diffuser with the necessary instrumentation to measure the drag and downforce acting on the vehicles. Wind speed can vary from 0 MPH to 20.1 MPH with the use of a variable transformer. Six various body styles have been tested for ...

CO2 Dragster Dynamics HowStuffWorks

By putting your car into the wind tunnel and putting a fog vapor into the air stream, you can track how air flows over the car's body. You want a smooth flow of air free of swirling currents called eddies. If you have too many of those, you may want to use sandpaper to smooth out the design, or go with a new one altogether. Up next, we'll examine what makes CO2 dragsters go: The power of ...

About this site

Before starting the wind tunnel and collecting data, make sure: Wind tunnel is held together by springs. Wind tunnel is air tight such that air can only enter through the contraction cone and exit through the diffuser/fan. All equipment is plugged in. Force sensors are properly calibrated. Model is mounted on the threaded rod in the test section.

Ask an Expert: Measuring Drag in a Wind Tunnel

20/12/2015  Measuring Drag in a Wind Tunnel. Post by Madisen2015 » Sun Dec 20, 2015 9:05 pm . Hi, I want to build a simple wind tunnel and try to measure the drag of a styrofoam cone object. I would like the cone to represent a rocket, and to see if a cone with dimples carved, verses lines, versus smooth would have less drag and therefore use less fuel in takeoff when launching into space. I have done a ...

‘I think that our new dimpled hub is pretty analogous to a racecar driveshaft, and on the hub we are seeing 14-20g of drag reduction at low yaw angles in the wind tunnel (at 30mph) and this is only a very small part,’ explains Poertner. ‘At the higher yaw angles the flanges (the Zipp hub is only 100mm end to end with flanges at each end), start to block the airflow over the centre of the ...
