Description

The invention relates to aviation, namely to aircraft and helicopter engineering, and can be used to create an aircraft of high lifting power: a crane helicopter, as well as the creation of small aircraft: reconnaissance or children's toys, creating an environmentally friendly device of the future, as well as an apparatus having a high resource and reliability.

A known method for creating a lifting force, implemented in the design of a device for creating a lifting force, GB Patent No. 2270510, ISM 1/96, 64 C 19/00, (World Invention Issue 033 No. 01/96), which consists in creating a lifting force by driving air through the annular channel in the disk wing using a fan driven by an electric motor.

The disadvantages of this method are: a small area swept away by the fan due to the location of the screws inside the disk, a small efficiency of the screws due to their small size and high speed, power loss to compensate for the torque.

A known design of a device for creating lifting force according to the aforementioned patent GB No. 2270510, ISM 1/96, 64 C 19/00, which is an unmanned aerial vehicle with battery power. The electric motor rotates the fan, which drives air through the annular inlet channel and the annular outlet channel. This creates a lifting force. Servo-controlled blades of the output channel provide a parry torque. The aircraft is controlled by changing the position of the center of gravity by moving the loads.

The disadvantage of this design is: the need to install a gearbox to drive the fan, to control by changing the center of gravity, additional loads and free space inside the apparatus are required, which reduces the useful lifting mass.

The closest in technical essence to the proposed method for creating aerodynamic lift is the method of creating aerodynamic lift, implemented in the design of the patent "wing Pavlov" RU No. 2101215 from 10.01.98, 6 V 64 C 27/18, 27/22, which consists in the creation of lifting force with the help of blades extending from a rotating disk, the rotation of the disk is carried out using compressed air flowing from nozzles located around the perimeter of the disk.

The disadvantages of this method are: loss of power to compensate for the reactive moment (the moment in the bearings), which leads to a decrease in the payload, the effect of high temperatures and pressures on the cavity of the disk, leading to a decrease in the life of the structure and a decrease in the reliability of the apparatus as a whole, high noise level at the air from nozzles, which makes the device not environmentally friendly and reduces the area of its possible use.

A known design for creating aerodynamic lifting force according to the aforementioned patent "wing of the Pavlov’s plane" RU No. 2101215 from 01/10/98, 6 B 64 C 27/18, 27/22, which is a round wing in the form of a thin-walled shell with blades, nozzles are made around its perimeter for the flow of compressed air, creating a rotational movement of the wing. In the inner cavity of the wing there are blades connected by cables to a drum mounted on the fixed axis of the wing. The blades have the ability to move out of the wing cavity by centrifugal forces during its rotation, forming a rotor, and be removed by folding the cables onto the drum during its braking.

The disadvantages of this design are: the need to install gas turbine engines, which makes it impossible to create small-sized devices, the need for additional rudders, which also increases the mass of the device and complicates the control system, thereby reducing its reliability, power loss during compression (discharge) of air, friction losses when air moves along the wing channels, reducing engine efficiency, which leads to a decrease in payload.

The solved problem of the proposed method and device is the creation of an environmentally friendly aircraft with a large resource, high reliability, high carrying capacity and vertical take-off.

In the method for creating aerodynamic lifting force, which consists in creating a lifting force using a rotating disk with blades, aerodynamic lifting force is created by two rotating disks that rotate relative to each other by a drive from electromagnetic coils located around the perimeter of the disks.

In the device for creating aerodynamic lifting force, consisting of a rotating disk with blades, two disks are introduced, mounted on the same axis with the possibility of rotation relative to each other, and electromagnetic coils located along the perimeter of the disks, the electromagnetic coils of one disk being connected to an alternating current source magnetic poles, forming a stator of an electric motor, and the electromagnetic coils of the second disk are connected to a current source through a collector with the possibility of changing magnetic poles during rotation a disk forming a rotor of an electric motor.

To clarify the technical nature of the invention, we consider figure 1 - a top view of the device for creating aerodynamic lifting force, figure 2 - section of the disks in diameter, figure 3 - the interaction of electromagnetic coils, where:

1 - top disk

2 - electromagnetic coil of the rotor,

3 - aerodynamic fairing disks,

4 - blades of the upper disk,

5 - lower disk

6 - electromagnetic coils of the stator,

7 - the blades of the lower disk,

8 - axis of the disks,

9 - collector,

10 - current source.

The device operates as follows.

The electromagnetic coils 2, 2 ', 2' ', 2' '', 2 '' '' in Fig. 3 of one of the disks 1 are connected to a current source 10 so that their magnetic poles alternate, forming an electric motor stator, electromagnetic coils 6, 6 ', 6' 'of the second disk 5 are connected to the current source 10 through the collector 9 so that they change their poles when the disk rotates, forming a motor rotor, where the interaction of the magnetic poles of the coils is shown: the 6' 'coil is repelled from the 2' '' 'coil and is attracted to the 2 '' coil, coil 6 'is pushed away from the 2' 'coil and attracted to the 2' 'coil, coil 6 When rotation of the disc reverses poles from minus to plus, after the disc rotation through a certain angle through the collector coil 9 connects to current source 10 so that it is attracted to the coil 2 and repelled from the coil 6 '. The torque, consisting of the magnetic forces of interaction of all the coils located at a certain radius R from the axis of the disks of FIG. 2, drives the disks 1, 5 with the aerodynamic blades 4, 7 attached to them. Aerodynamic blades 4, 7, rotating in air, create lift.

The advantage of this method is that the coils located on a large radius create a large torque, which eliminates the need to use a gearbox, which in turn facilitates the design and increases the carrying capacity. The use of two discs avoids the appearance of a reactive moment. High reliability and stability in the operation of the electric drive can improve the reliability and resource of the aircraft. The use of an electric drive allows you to create an environmentally friendly aircraft of the future.

The advantage of this design is that the use of two disks compensates for the reactive and gyroscopic moments, the high efficiency of the electric drive, there is no loss of power during compression and injection of air into the disk, and there is no high temperature effect on the disk design. The device, used as a crane or bench model, can operate from current sources located on the ground. In autorotation mode, the device can accumulate electricity.
