ENHANCED VEHICLE EFFICIENCY USING AIRFOIL TO RAISE REAR WHEELS ABOVE ROAD SURFACE

摘要

A vehicle with a body, two front wheels and at least one rear wheel. An airfoil is mounted to the body with adjustability in angle of attack, and at least one of the front wheels is driven to permit acceleration to a cruise speed at which the airfoil provides sufficient lift to raise the rear wheel off the road while the front wheels maintain contact with the road. Lift may be modified by at least modifying velocity and modifying the angle of attack of the airfoil. This vehicle provides advantages in comfort and efficiency due to reduced friction in contact with the road and imperfections on the road. The wing may also be adjusted to increase downward force on the rear wheel.
