A year ago, XStream Trucking received first prize at First Look West 2016 for the prototype of the fairing GapGorilla for caravans, and today they are ready to release their latest offspring to the North American market – A marketplace full of trucks and wagons, which all need solutions to reduce fuel costs.
The aerodynamic resistance of a moving truck with a trailer is so great that if it is minimized, it can reduce fuel consumption by an impressive 12%. In theory. In practice, there is an empty space between the cabin and the trailer, which must be kept for so to aid manoeuvering. But this gap generates turbulence – Turbulence that TruckWings technology is designed to get rid of.
Structurally, it represents a complex of folding panels, which in their open state completely cover the emptiness behind the cabin. These panels are made of light composite materials with reinforcement, are shock-resistant and resistant to the ravages of weather . Automation opens the panels when the truck is moving at high speed along the highway, but fold when the truck slows and is set to turn, so as not to interfere with the manoeuver.
The developers tested the TruckWings for several years and went from a digital model to a full-size mock-up, tested in a wind tunnel. The existing prototype was tested on real roads with the involvement of officials and independent experts, and fuel economy was improved by 2-4%. It is estimated that it takes about 18 months to recover outlay costs of the system, and several of the largest US carriers are now poised to sign contracts with the manufacturer.
