For an aircraft (1) having a balancing torque and including a motor-driven propeller (5) arranged on a central axis (3), and a useful load container (6), a solution should be provided which would insure that the aircraft is capable of carrying useful loads in a stable flying attitude and with simple control means. This is achieved by that the central propeller (5) driven by the drive motor (4), on one hand, and relative thereto, the motor (4) and/or torque-balancing means arranged thereon, on the other hand, are rotatable in opposite directions and together are supported for rotation relative to the useful load container. At that, the drawing figure to be published: FIG. 1.
A telescopic vertical take-off aircraft is disclosed. The aircraft comprises a main rotor assembly 2 at the top of the aircraft which consists of an assembly of blades 3a, 3b and a rotor 4. Rotation of the main rotor assembly 2 is achieved by means of a main engine assembly 5. The main engine assembly 5 is connected to the main body 6 of the aircraft by a tilt enabling joint 7. The tilt enabling joint 7 enables tilting of the main engine assembly 5 relative to the main body 6 of the aircraft to occur in a controlled manner during flight. A universal joint 8 is used to allow tilting to occur. The tilt enabling joint 7 is fitted with hydraulic actuators 9, 10 and 11, that allow the tilting of the tilt enabling joint 7 to be controlled. When the main engine assembly 5 is tilted, the main rotor assembly 2 is tilted with it. Tilting of the main engine assembly 5 thus initiates changes in the direction of travel of the aircraft without the need to change the pitch angles of the rotor blades 3a and 3b. To counter the rotational force exerted on the main body 6 of the aircraft by the rotation of the main rotor assembly 2, an additional engine assembly 15 is attached to the main body of the aircraft, which rotates a secondary rotor assembly 16. The secondary rotor assembly consists of blades 17 and 18, and a rotor 19. Rotation of the secondary rotor assembly pushes air in a primarliy horizontal direction by way of the pitch of the blades 17 and 18. Telescopic tube assemblies 12 and 13 allow the distance between the base 14b of the tilt enabling 7 and the main body 6 of the aircraft to be varied.
A flying arrangement, consisting of at least one flying unit (10) that is able to start vertically and that can accommodate at least one person for flying freely within at least a hall (100,200), the boundaries (2,3,4,5,6) of which prevent a flying unit (10) from leaving the hall (100,200,300).
