Electroaerodynamic fairing is a device that performs a dual function: a) reduce counter the aerodynamic resistance of the environment, (b) acting as an independent source of electricity.

The technical field

The proposed device can be used in the field of electrical/automotive.

The level of technology

As a result of the patent study indicates that the proposed electroaerodynamic fairing has no analogues in the world of electro/automotive. Currently in truck and automotive uses mostly static fairings, which cannot be used as a stand-alone power sources.

Known for the following types of static fairings: cone, convex, elliptical. These devices reduce drag are used in commercial vehicles and mounted on the cab of the vehicle. The reduction of the aerodynamic resistance in them is achieved by reducing the angle counter the drag of the air. However, in the automobile, the automobile cannot be used, since the decrease of the oncoming wind resistance is achieved here due to the aerodynamics of the car body.

Offer electroaerodynamic device is istwo intended primarily for automobile, electrical/automobile transport. On the totality of symptoms is the closest to the proposed Radome include the following devices.

Device (US 2002193947, 10.07.2002), which contains a fairing mounted on the front of the car, consisting of pipes and panels, and vacuum plate with holes mounted on the rear flat side of the car.

The disadvantage of this device is static and low coefficient of technical efficiency.

Known site reduce drag and lift forces of the car (FR 200309926, 13.08.2003)containing at least one, located on the front side of the vehicle air intake, which is connected through the suction line to the device, forming a veil in front of the front wheel of the car to change the formation to the flow of air flow of this wheel.

The difference with this device is its application to the front wheels, not just the chassis of the vehicle. The disadvantage of the site is that it cannot be used as a standalone power source.

A device (GB 200103091, 08.02.2001), consisting of strips having serrated surface of the car. During the movement of the teeth strips create a zone of air microcavity enhancing the flow of the car the main air flow.

The disadvantage of this device is a hundred what was mentioned and the fact that it cannot be used as a standalone power source.

A device (US 46677, 16.01.2002), which contains the movable and stationary plates and two elastic fasteners. Fixed fixed into the slots on the car body. A movable plate pivotally connected with a fixed plate with elastic detail, in such a way that it moves up and down depending on the pressure of the air flow. The device allows you to stabilize the body of the car when driving at high speed.

The disadvantage of this device is the low efficiency in the reduction of the counter-resistance of the environment, and that it cannot be used as a standalone power source.

A device (EN 4628311/11, 30.05.94). It serves the invention in the form of aerodynamic wings with a cross-section, plugged above the body of the car. The disadvantage of this device is its static nature, low technical efficiency, and cannot be used as a standalone power source of electricity.

It is also known a device for reducing drag of vehicle, designed for freight transport (EN 20051089245/11, 29.03.2005). It is a rotating drum, the axis of which is parallel to the ground and perpendicular to the axis of the vehicle, sabiendo what about the mechanism of rotation - screw-Grover. A disadvantage of this device is the low technical efficiency, the impossibility of its use in a passenger automobile, as it rasschitanna to overcome flow arising from differential aerodynamic pressure in the shadow of the vehicle between the cab and the body.

Disclosure of inventions

The device is designed to reduce counter the aerodynamic resistance of the environment, as well as to convert it into a source of electricity. The objective is achieved by rotation of the fairing under the pressure of the incoming flow. Rotating fairing smoothly and evenly distributes the incoming air flows along the entire chassis of the vehicle, which results in a decrease in frontal aerodynamic drag by 25-30%. The energy of the counter-resistance of the air mass with a rotating Radome connected to the generator can be converted into electricity. Because of this fairing can be used as a standalone power source.

The essential features of the device.

Fairing (figure 1) includes the following structural elements: metal rod 1, two bearing 2 and a cylindrical housing with ribbed surface 3.

The implementation of the invention

Cilindric the ski body (3) is put on two fixed on the rod bearing (4), that creates the possibility of rotational effect of the fairing side view (figure 5). The unit is mounted under the hood, in the front part of the chassis of the vehicle, so that a large part of the flow of air hit him. On the surface should be no more than half of the hull fairing (figure 2).

Principle: when driving fairing starts to rotate under the influence of air flow. This allows you to more evenly distribute the air mass along the entire chassis of the vehicle and leads to a decrease of the counter aerodynamic resistance. Rotating fairing connected to the generator, which can convert the aerodynamic resistance in the electric power and can be used as an independent energy source.
