6. Fairing on a truck tractor

Fairing - a special design that facilitates the flow of an object around a stream of gas or liquid , which leads to a decrease in aerodynamic resistance to movement. Fairings are widely used in technical devices moving at high speed, such as cars and airplanes , since their introduction increases the possible speed and reduces fuel consumption . Of particular importance among all types of fairings for moving vehicles is the head fairing , since it is he who largely determines the air resistance.
