Abstract: A post pressurizing material treatment for bodies moving through fluid includes a series of compartments joined to the rear surface of the body. Each compartment is sealed by a top wall, a bottom wall, a pair of side walls and a front wall and is open at a rear end thereof. Each compartment retains at least one V-shaped base having diverging walls opening into the rear end of each compartment. Post pressurizing material is secured in a spaced between the walls of the V-shaped base for trapping fluid flow and accumulating forward pressure between the walls of the V-shaped base so as to reduce drag and propel the body forward.

Abstract: A post pressurizing material is preferably embodied in a layered system of gridwork in the form at least two back-to-back screens which can be attached to the rear surface of a body with a peripheral border around the screens. The screens have the ability to entrap fluid flow and accumulate pressure therein so that, in applied form, it will reduce drag and simultaneously push or propel the body to which rear surface it is attached into the fluid.

Abstract: A dynamic surface element is located on a substantially smooth surface of a body moving through a fluid for improving the movement of the body. The dynamic surface element includes a lower wall provided on the surface of the body, the lower wall having a front edge extending rearwardly to a back edge. An upper wall rises upwardly and rearwardly from the lower wall with the upper wall having a lower edge connected to the lower wall, and an upper edge spaced above the lower wall. A pair of sidewalls connects the upper and lower walls and together with the upper and lower walls forms a chamber accumulating internal pressure offset by external pressure caused by fluid flow against and over the upper wall as the body moves. The dynamic surface element interrupts layers of fluid normally accumulating on the smooth surface of the body moving through the fluid and creating drag.

Abstract: A post pressurizing material is preferably embodied in a collection of dense, flexible elements oriented generally perpendicularly and extending from a flexible mounting base which can be attached to the rear surface of the body. The elements have the ability to entrap fluid flow and accumulate pressure therein so that, in applied form, it will reduce drag and simultaneously push or propel the body to which rear surface it is attached into the fluid.

Abstract: A body driven through air or other fluid has a surface including a plurality of similar wave-shaped elements, each having a curved nose connected to an extended tail. Each element extends substantially across the body and the elements are located in parallel relationship and generally oriented across the path of the air. The adjacent elements may be connect tail to nose or may be spaced with a flat surface connection or a small modified surface connection between individual elements or groups of elements.

Abstract: A body moving through a fluid has air control and directing elements on its outer surface. The elements are laterally and longitudinally spaced and includes elements having a forward curved nose or front portion and tapered tail portions projecting outwardly from the main body. Each of the elements and body space between the elements is covered with parallel ribs extending parallel to the elements. Special elements may include raised flexible tail portions for further interacting with the air or other fluid. The shape of the elements and the ribs are varied in accordance with the desired interaction with the fluid to create the multi-dimensional fluid movement over the surface. Various different shapes and configurations of the elements are described.

Abstract: The exterior surfaces of an automobile is formed with a series of immediately adjacent or closely spaced wave-shaped flutes which extend longitudinally at an angle to the direction of travel and form a herringbone pattern. A series of parallel dividing walls extending in the direction of forward vehicular travel are integrally formed with the fluted surface. The dividing walls in one embodiment include trailing tapered projections slightly above the plane of flutes. The base of the flutes may have smaller rearwardly inclined pin-like projections to optimize air action within the flutes. In another embodiment, the curved or fluted member are shaped as feathered members with a plurality of parallel dividing walls for channelling the air.

Abstract: An automobile includes a main front air screen generator having a curved wall member extending rearwardly and upwardly to a crest. A central deflector plate develops an air screen in front of the vehicle and a low pressure pocket behind the curved member. The surfaces of the automobile include minute wave-shaped flutes, each including a trough which extends upwardly and rearwardly to a relatively sharp crest and then breaks downwardly and forwardly into the next trough such that any impactive air moves over the surface with engagement only at the crest portions. A screen covers the flutes on the back surfaces and curved vances extending rearwardly and upwardly may optimize the pressure condition.

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.
