If you think that I will talk about UFOs, then you are mistaken … Today the story is about a completely terrestrial technology.
But first the question is: What do you see in the picture above?
Personally, I see an aircraft with unique aerodynamic characteristics. This shape of the body is able to balance the action of physical forces, reduce air resistance and make it possible to fly at the highest speed.
That is why one day the idea arose in my head to develop something similar.
Atmospheric disc flying.
The cockpit in this design should be centrally located to provide the best visibility for the crew being far from all edges.
By the way, the invention is patented and can be sold.
We make propellers around the cabin, which rotate in different directions.
Promotional video:
You know, helicopters can start spinning in circles if the tail rotor doesn't work. Here this issue is solved by different directions of the propellers, but they must have the same area.
The propellers can be powered by motors, for example two (well, for better weight distribution and for greater safety if one motor fails).
Also, for safety, we have a parachute system with the ability to automatically open.
Propellers in the tail section provide forward movement, and turn occurs by braking one of the propellers or by opening / closing it. Also, the shutters automatically adjust the inclination of the disc.

Next I bring to your attention a small gallery and a description for the sophisticated.
The atmospheric disc works as follows:
Vertical movement.
The outer (2) and inner (3) propellers (together representing the vertical flight propellers) located in the disc body (1) have a connection with the atmosphere through special windows (24) and spin at the same speed evenly. In this case, the working area of the screws (i.e. the area occupied by the screws in each window) is the same for both screws.
Thus, the equality of the vertical flight propeller area does not allow the disk to twist in one direction or another relative to the propeller rotation axis.
When the lift becomes approximately equal to the force of gravity, the disc determines (by means of sensors, gyroscopes, etc.) its deviation from the horizontal position. Then the curtains of air flows (4) are turned on, which partially block the air flow in one or another window (24), or in several windows at once, by the required amount.
After that, the disc can freely rise into the air and retract the landing gear (20).
Horizontal movement.
To ensure horizontal movement, the horizontal movement screws (5) driven by the drive (22) begin to pump air into the housing (1) in the area of their location. In this case, the air flow (19,23) is discharged through the nozzle (6) moving the disk in a horizontal direction.
For more stable operation, it is envisaged that the screws for horizontal movement should be arranged in pairs, i.e. if one screw is on the top of the case, then the second screw is on the bottom of the case.
In cases of creation of a specialized type atmospheric disk with special requirements regarding speed or other characteristics during horizontal movement, it is possible to use a jet engine, magnetic, photonic or any other type of device instead of horizontal propellers.
The propeller brakes are provided for turning the atmospheric disc (10). So, with the horizontal movement of the disc, when it becomes necessary to change the direction, the pilot, or a computer program, gives a signal to the brakes of the external (2) or internal (3) rotor. The corresponding screw is braked by the brake (10), while the gearbox (11) redistributes the thrust by increasing the rotation speed of the other screw. In accordance with the magnitude of the difference in rotation, the disc turns to the side, which is caused by the occurrence of a reactive torque from the unbraked propeller.
When flying in a crosswind, the disc is able to resist it due to almost the same aerodynamics on all sides. The disc body itself is the same except for the nozzle (6) at the rear. But the cabin (8) has a different shape than round. And if from the front part of the cabin (8) due to its small width it has low resistance, then its side side has a great length and resistance is higher. Nevertheless, given that the cabin is only about 10% in cross-section, and 90% falls on the disk itself, and also given that the cabin is also given an aerodynamic shape, it should be considered that the difference in aerodynamic drag in frontal and side winds is insignificant.
In the event that a crosswind or wind of any other direction affects the disk at an angle to the horizontal plane of flight from below or from above, then the horizontal position of the disk is supported by air curtains (4).
If necessary, the disc can move forward from the rear thanks to the reverse airflow mechanism (25). This mechanism closes the direct exit of the air flow (19) from the nozzle (6) so that the air flow escaping from the nozzle is redirected along the body of the disc (1) forcing it to move in the opposite direction.
Energy sources.
The energy source (14) is located mainly under the cab, as close as possible to the lower part of the body (1). This is done in order to lower the center of gravity of the entire structure and the best weight distribution. It is assumed that, in the simplest version, a gasoline engine with a generator, fuel cells or batteries with a reserve of electricity (mainly for UAVs and game discs) can serve as a source of energy, since electricity can be distributed in the best possible way between electrical consumers (electric motors, control systems, etc.). etc.).
At the same time, there is the possibility of replenishing electricity reserves, for example, by placing solar panels on the disc body (1).
From the energy source (14), energy is supplied to the propeller drive motors (9) and to other systems of the disc. And the motors (9), in turn, unscrew the screws (2,3).
Safety.
To ensure safety, the atmospheric disc has two propeller drive systems.
They include a propeller drive motor (9), a reducer (11), gears (12).
In case of failure of one of the propeller drive motors (9) or other breakdown, which will lead to the impossibility of its operation, the task of rotating the outer (2) and inner propeller (3) is assigned to the second system completely. At the same time, it is possible to increase the load on the backup system and reduce the characteristics of the disc. But this duplication allows you to safely land the disc on the ground.
The energy source also contains redundant systems and can have a separate view (for example, several batteries can be used that are independent of each other).
To avoid getting into the vertical flight propellers and into the horizontal flight propellers of parts of the human body, objects, animals or birds, the propellers are supposed to be covered with a grill from the open sides.
Emergency situation.
In the event that there is a complete failure of the main propellers, the outer (2) and inner (3) disk will begin to fall Due to aerodynamic features, the fall can be uncontrollable (the disk can start falling at an angle of 90 degrees relative to the ground and rotating around its axis), which makes it impossible for parachutes to fire (7).
Since the cockpit (8) of the disc has a different shape from a circle and there is a slight difference in frontal and lateral resistance, this prevents rotation.
In addition, at the beginning of the fall, the aero petals (13) are automatically triggered, which are extended from the body at a right angle. They increase aerodynamic drag in the upper part of the hull, which, together with a lowered center of gravity, should lead to the fact that the atmospheric disk will tend to a more horizontal position when falling, while the upper part of the hull will be oriented partially upwards.
In addition, some of the aeroplates (13) in the extended position have the ability to rotate, which should also prevent the rotation of the disc around its axis.
Thus, the atmospheric disc is able to stabilize its fall and enable the emergency parachutes (7) to operate, which, when opened, will slow down the fall of the disc and save the lives of passengers and the equipment in a maintainable condition.
Use as a UAV, gaming aircraft.
The atmospheric disk can be used as an unmanned aerial vehicle. In this case, the cab (8) may not be available. In addition, the disc can be retrofitted with additional systems.
And with a decrease in the size of the disk, it can serve as a replacement for quadcopters or as a game aircraft. At the same time, the main feature is that thanks to the screws (2,3) retracted inside the case, it is quite safe both when flying in the city, and in the event that it is launched indoors.
