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.
