Abstract

The airlift comprises an engine-propeller unit and means for retention of the engine-propeller unit relative to the earth'"'"'s surface, fixed on the above unit in the axis of rotation upward of the center of gravity of the engine-propeller unit. The means for retention of the engine-propeller unit relative to the earth'"'"'s surface comprise solely a wire rope or a wire rope and an arm fixed inside the engine-propeller unit, or a wire rope and a frame embracing the engine-propeller unit fully or partially.

Claims

1. The airlift comprising an engine-propeller unit and means for retention of the engine-propeller unit relative to the earth'"'"'s surface, fixed on the engine-propeller unit in the axis of rotation of the propeller, wherein the means for retention of the engine-propeller unit relative to the earth'"'"'s surface is fixed above the center of gravity of the engine-propeller unit.

2. The airlift as set forth in claim 1 wherein the engine-propeller unit comprises a frame or a hollow cylinder on which at least one electric motor is placed, the electric motor having a ring-like stator part embracing the frame or the hollow cylinder and the means for retention of the engine-propeller unit relative to the earth'"'"'s surface being fixed inside the frame or the hollow cylinder.

3. The airlift as set forth in claim 2 wherein the means for retention of the engine-propeller unit relative to the earth'"'"'s surface are made in the form of a wire rope.

4. The airlift as set forth in claim 2 wherein the means for retention of the engine-propeller unit relative to the earth'"'"'s surface are made in the form of a wire rope and an arm comprising two knees joined in series and a drive to adjust the angle between the knees, one knee of the arm being connected to the wire rope and the other knee fixed inside the frame or the hollow cylinder and capable of rotating around the propeller'"'"'s axis of rotation.

5. The airlift as set forth in claim 1 wherein the means for retention of the engine-propeller unit relative to the earth'"'"'s surface are made in the form of a wire rope and a frame fixed by means of a spherical or gimbal joint on the engine-propeller unit.

6. The airlift as set forth in claim 5 wherein the frame of the means for retention of the engine-propeller unit relative to the earth'"'"'s surface is fixed on the body of the drive of the engine-propeller unit.

7. The airlift as set forth in claim 6 wherein the engine-propeller comprises two propellers and the frame of the means for retention of the engine-propeller unit relative to the earth'"'"'s surface is fixed below both propellers.

8. The airlift as set forth in claim 5 wherein the engine-propeller unit is located inside the frame of the means for retention of the engine-propeller unit relative to the earth'"'"'s surface.

9. The airlift as set forth in claim 8 wherein the engine-propeller unit comprises an electric motor and a bearing support placed in the stator part of the electric motor for the frame of the means for retention of the engine-propeller unit relative to the earth'"'"'s surface, the frame being fixed by means of a spherical or gimbal joint at the end of the bearing support and the means for retention of the engine-propeller unit relative to the earth'"'"'s surface comprising additionally an electric cable that connects a ground-based electric power source to the electric motor of the engine-propeller unit.

10. The airlift as set forth in claim 9 wherein the bearing support is made hollow to place therein the electric cable that connects a ground-based electric power source to the electric motor of the engine-propeller unit.

11. The airlift as set forth in claim 5 wherein the engine-propeller unit comprises two propellers and the frame of the means for retention of the engine-propeller unit relative to the earth\s surface is fixed in between the first and the second propellers.
