Trailer aerodynamics improves with Formula 1 technology
Cartwright Group, the body and trailer manufacturer is using computational fluid dynamics (CFD) technology from Formula 1 to improve trailer aerodynamics. In partnership with Manchester Metropolitan University Cartwright Group is using the technology to develop low-carbon trailers.
A Cartwright Director explains "CFD has replaced the wind tunnel. All the Formula 1 teams use it. By using particles, which you can alter in size, it shows up where the aerodynamic deficiencies are on the product." Desktop based CFD is also more cost effective than using a traditional wind tunnel.
The Cheetah Fastback is the first trailer design to have used CFD, and includes variable-air suspension system which reduces drag by lowering the running height of the trailer. Cartwright explains "It uses a wedge-shaped chassis and the roof line drops down to suite the shape of the chassis."
New trailer designs are helping haulage and logistics firms make operational savings. Existing fleet usage can also be optimised with Satellite Tracking technology such as Axscend Trailer Management that uses GPS Trailer Tracking to give visibility of trailers, and information on usage and off-road time. Trailer usage can then be optimised driving down operational costs and improving profit margins.
