Description

The invention relates to the automotive industry and can be used as a universal vehicle operating on roads and in the air.

The well-known Yo-Mobil car (newspaper Za rulya No. 13 (284), July 2013), in which the engine drives an electric transmission using an electric generator with a capacity of 60 kW (see Fig. 1).

The operation of the "E-mobile" involves the use of roads.

The disadvantage of this car is the inability to fly.

The “flying machine” is known from the Internet, fig. 2 (Curtiss Autoplan Autoplan Glen Curtis - USA). This is a four-wheeled vehicle, on which three-level wings are installed, with a wingspan of more than 12 m, a four-bladed propeller. This plane was transformed into a car by dismantling the wings. Wings were stored in the hangar at the airport. An airfield was used for take-off and landing of a flying car.

The disadvantages of this flying car (autoplan) are:

- the need to use the airfield for takeoff and landing, due to the large lengthening of the wing,

- the need to dismantle the wings when switching to another mode of operation of the car,

- the presence of a warehouse for storing dismantled wings.

The closest technical solution to the proposed invention is a flying car company - "terrafugia Transition" - USA (Internet), Fig. 3.

This four-wheeled vehicle is equipped with folding rigid wings, a tail feather with a rudder in the horizontal plane and a propulsion device (pushing four-blade propeller). After landing, the wings of the car are folded, and it can already go to city roads as a car.

The prototype considered has the following disadvantages:

- preparatory work for take-off on the deployment of wings,

- the use of an airfield for take-off and landing in connection with a sufficiently large extension of the wings,

- wings and tail are parasitic mass for a car when it is moving on roads, which increases fuel consumption.

The aim of the invention is to expand the operational capabilities of a car, which without conversion can drive along the highway, take off from it and land at a relatively low speed, i.e. “Flying car” has two operating modes: car mode and airplane mode. In this case, when the flying device is operated in car mode, the propulsion is wheels, and in airplane mode, the jet propulsion is a fan or propeller. In addition, during the operation of the car, thanks to the presence of an additional propulsion, its off-road patency is increased. The use of the wing when driving on the highway allows you to control the pressure of the wheels of the car on the road due to the presence of pressure sensors, due to which it is possible to optimize fuel consumption and the stability of the car on turns.

Four-wheeled vehicle 1 (see Fig. 4) is equipped with sensors for wheel pressure on the road and a rigid, fixed, rectangular wing 2, with a small elongation installed at an angle α to the horizontal. The overall dimensions of the wing in terms of this are close to the size of the car, which allows it to operate on existing roads. Between the lower surface of the wing and the roof of the car provides sufficient clearance for normal aerodynamic operation of the wing. To regulate the lifting force, the wing is equipped with mechanization - two slats 3 and two flaps 5. To increase the lifting force of the wing, the slats 3 are shifted in the direction of arrow E and the flaps 5 in the direction of arrow B. To increase the wing area and its lifting force, the flap 5 moves in the direction arrows D. The mechanization of the wing changes (increases) its lifting force and allows the vehicle to take off from the road at a relatively low speed without conversion.

When a car with a wing takes off, its pressure on the road can change according to the formula:

P = Gm-Qcr.,

where P is the pressure of the car on the road,

Gm - take-off mass of a car with a wing and a load,

Qcr. - wing lift (changes during take-off depending on the speed of movement).

At takeoff GM = Qcr. and the car’s pressure on the road is zero.

In the mode of movement of the car on the road, it is sometimes advisable to increase the pressure of the car on the road. This is achieved by changing the direction of the action vector of the lift force of the wing, as a result of which the addition of the lift force of the wing with the weight of the vehicle occurs and then the maximum pressure force on the road will be:

P = Gm + Qcr.

A change in the direction of the wing lift vector and its value are achieved by moving the slat 3 in the direction of the arrow F and the flap 5 in the direction of the arrow A.

The presence of the wing during operation of the car on the road allows you to control and adjust the pressure force of the car on the road, as a result of which you can choose the optimal value, which ensures lower fuel consumption and increased stability of the car when cornering. The vehicle’s pressure on the road is measured using four sensors installed between the bridges and the car body, for example, on shock absorbers. The sum of the readings of the four wheel pressure sensors on the road indicates the proximity of separation from the ground during take-off, and the difference in the readings on the roll and the center of gravity of the machine, taking into account the aerodynamic component (wing lift). The movement of the car when the machine is taken off the ground and in flight is provided by a propulsion device, for example, a jet electric fan or a propeller 6, creating horizontal traction and working from the car engine. In the variant with a propeller, the torque from the engine 7 is transmitted to the screw 6 using the shafts 9 and gearboxes 10. See Fig. 4.4. The flight direction is adjusted using the rudder 8. The altitude parameters of the flight are changed by changing the aerodynamic parameters of the wing and the operating mode of the jet propulsion. The mover is started and turned off by the signal of pressure transmitters installed on the vehicle, or manually.

To reduce the influence of end breakdowns and avoid stalling in flight, stabilizers 4 are installed on the wing and on the suspension struts of the wing.

To use the car in airplane mode, an additional control system is provided, which includes: a steering wheel, a wing mechanization control system, a propulsion control system, a flight speed measuring system, an altimeter, a compass and an electronic display with four pressure sensors.

The technical and economic effect of the introduction of this invention is created by expanding the operational capabilities of the car and allows you to overcome areas without roads.

The implementation of the invention

To implement the invention, the serial car 1 is retrofitted: force measurement sensors are installed on the suspension dampers, wing mounting supports 11 are installed in the body stiffness belts, wing 2 with low elongation and mechanization with horizontal rudders 8 and jet propulsion 6 is installed, while the dimensions of the wing are close to overall dimensions of the car.
