WIND TUNNEL TESTING
Comfort is safety. A well-ventilated, quiet and balanced helmet is much less tiring for a rider to wear, allowing them to focus more effectively on riding.
During wind tunnel testing, comfort is measured using the following criteria:
- X-DRAG resistance to aerodynamic penetration
- Shows the helmet’s resistance to motion and therefore the force the neck muscles need to exert to oppose this resistance.
- Δt Ventilation heat exchange
- Measurement of the helmet ventilation system’s ability to convey heat and moisture away from the rider’s head.
- Measurement of buffeting
- caused by turbulence around the helmet at different speeds (buffeting frequency in MHz).
- Measurement of the lift
- the helmet exerts on the rider’s head in Newtons.
