STEM Racing Air Trace Visualisation System
Everything you need to test your car designs.
Price on application
This product is built to order and the quote can be customised to your specification.
Clean, safe and easy to operate
Aerodynamic testing
An essential part of the design, test and make process.
This system is designed to visualize how air flows over and around a race car during motion. It typically uses smoke, coloured threads, digital simulation, or particle tracking to create visible air “traces” that reveal aerodynamic behaviour, such as drag, lift, and turbulence.
The data gathered helps in:
- Teaching students about fluid dynamics and aerodynamics
- Optimizing car design for better performance and fuel efficiency
- Demonstrating real-world physics concepts in a visual and interactive way
- Modern systems may include wind tunnels, sensors, and computational fluid dynamics (CFD) simulations to enhance accuracy and educational value

Air Trace Visualisation Tunnel
Featuring variable wind speeds, the Air Trace Visualisation Tunnel is simple to use, compact in design and easy to set up.
Use the tunnel with the Air Trace Smoke Generator to run smoke-like vapour over your STEM Racing Car to demonstrate its aerodynamic capabilities.

Air Trace Smoke Generator
The Air Trace Smoke Generator will produce a steady stream of smoke-like vapour, continuously when connected to a mains adapter.
Vapour will disperse quickly, so you can clearly see the air flow pattern without flooding the tunnel with thick fog. The generator comes complete with a robust carry case.
Smoke Generator supplied as standard with Air Trace Visualisation System.
