ABSTRACT:
A land, water or air vehicle has a jet air stream unit mounted in front with a plurality of distributed jets generated immediately preceding the front wall portion of the vehicle to reduce the opposing pressure as well as the mass of air with the resulting greater ease in movement of the vehicle. As applied to an automobile type vehicle, an air pump is located immediately behind the radiator so as not to unduly interfere with the air flow through the conventional radiator. A small air jet forming unit is mounted in front of the vehicle having an inlet connected to the air pump and outlets directed at right angles to the line of motion. The jets are generally in a semi-circular pattern with the lower portion free of jets for removal of the air from immediately preceding the automobile while permitting sufficient air flow to the radiator. In winged aircraft, an appropriate air screen apparatus is secured to the forward or leading edge of the wing to produce air jets directed normal to the direction of the movement of the air foil section to minimize the wind resistance and effectively control the contour of the air foil section. In watercraft, an air or water jet screen may also be created below the water line to part the water and reduce the opposition to movement through the water.
