Description

 The invention relates to the field of automotive industry and can be applied in shipbuilding, in vehicles with land and surface modes of transportation such as cars, snowmobiles, sledges, planing boats and boats, surface-winged ships, and it is possible to use the invention on air-moving vehicles etc.

 In this particular case, we are talking about the use of air-lifting surfaces (wing-shaped planes), as applied to passenger cars.

 Known vehicle with ground-based mode of movement in the form of a car equipped with an air-lifting device with a wing.

 Its disadvantages include: 3-wheel version of the car, applicable for sports purposes, with a valid passage of the front wheel.

 This tool does not have a system of air regulation of the wing — the regulation of air flow and increase of the bearing capacity of the wing is carried out by spatial variation of the plane itself; There is no system for stabilizing track stability, etc.

 Another prototype was a VAZ-2108 car, described in the publication DOSAAF, in 1989, p.11 "Front-wheel drive cars VAZ".

The disadvantages of modern cars include the fact that in addition to its own mass (the weight of a fully charged and equipped vehicle, without payload), it is also necessary to move the payload (P _M ) in the form of passengers and cargo, in particular the payload (load) and VAZ-2108 is estimated at 425 kg.

 If the unladen mass, which forms the weight basis of the car, is formed by manufacturers and remains constant for a particular brand (the mass is assigned the role of the main guarantor of safe movement of the car), then the net mass (load) included in the total mass is variable: the volume of the latter is directly dependent of the number of passengers carried and the volume of cargo carried.

 Naturally, with a decrease in the volume of the payload, more favorable conditions are created for the operation of vehicles, the lightness of the machine ensures its speed, fuel is saved, the operating conditions of the machines improve, etc.

 The desire to achieve these goals is devoted to the present invention - to reduce the level of the destructive effect of the loading mass on the vehicle to a minimum (of course, with a guaranteeing condition for ensuring the safety of passengers).

 This is achieved by equipping the car with an aerial lifting device located above the car cabin, in order to reduce the payload and improve the performance, the vehicle is equipped with flat side stabilizers, between which there are wings that are made in the form of two aerodynamic surfaces, one of which has a slat , lateral stabilizers, and aerodynamic surfaces are interconnected so that one of the planes can be used for cre Lenia luggage.

 The drawing shows the proposed device.

 In the device on the roof of the car 5, elements with wing-shaped aerodynamic surfaces are mounted: wing 1, slat 2 and wing-trunk 3, which are connected by vertical (longitudinal) planes 4, which act as traffic stabilizers.

The principle of operation of this device is based on well-known aerodynamic laws by the formation of an air-lifting force (P _a ) arising during the movement of a vehicle under aerodynamic planes.

 This air force (support) is that opposing force that neutralizes the overload effect of the payload (mass).

 At the same time, the loading limit of the mass and the permissible limit of the aerial lifting force must be balanced (this is a prerequisite for ensuring the controllability and stability of the car).

P _m ≥ P _a .

 The effect of the air-lifting force is manifested at a transport speed of 20 km / h, and with an increase in transport movement, the force increases.

It is estimated that at a speed of 40 km / h, backwater is created on 1 m ^{2 of the} lower surface of the plane of 10 kg, at 60 km / h 30 kg, at speeds of 90-100 km / h up to 100 kg and more.

For example, an applied device to a VAZ-2108 car with a subchord area of 3.84 m ² at a vehicle speed of up to 72 km / h. able to provide air pressure of about 130 kg, respectively, at speeds of 90-120 km / h. a backwater of more than 300 kg is formed.

 The device includes two wings made in the form of two aerodynamic planes, a slat is located in the nose of one (lower) plane, the planes themselves are attached with their ends and flat side stabilizers, the upper wing is equipped with a luggage net and can be used as a luggage carrier.

 In the device, the reliability of movement of a vehicle (car) is provided by side stabilizers.

 The effectiveness of increasing (or lowering) the bearing properties of the planes (wings), regulating the load on the vehicle, as well as providing continuous (laminar) air flow around the planes is achieved by the position of the slat.

 Currently, by the staff and members of the Samara City Center for Children and Youth Creativity, an air-lifting device is being made on the basis of the Moskvich car.
