FAIRING WITH VORTEX GENERATORS

Fairings described herein aim to direct air streams into a gap formed between first a vehicle and a trailing vehicle, such as in a tractor-trailer combination, to reduce low pressure wake regions near the rear surface of the first vehicle thereby reducing drag forces on the vehicles. One or more embodiments of the fairings disclosed herein further aim to accelerate air streams such that the air streams travel quickly across the gap thereby reducing pressure forces on a front surface of a trailing vehicle. In some embodiments, the angle of the fairing relative to a surface of the vehicle is adjustable.
