Abstract
A rotary wing air vehicle has a body; at least one engine located on the body; a rotor that extends outwards from the body and rotates around its own axis in connection with the engine; at least one shaft extending outward from the rotor and triggered by the engine to rotate around an axis that the shaft extends from the rotor; at least two blades connected with the shaft and triggered by the shaft to move; at least one flap on the blade which provides drag force to the rotor by its movement to a closed position or an open position; at least one brake system which is located on the body in connection with the rotor to enable the flap to move to the closed position and/or open position so that a rotational speed of the rotor is adjusted by a user.
Claims10
A rotary wing air vehicle (1) comprising:
- a body (2);
- at least one engine (M) located on the body (2) for generating power for the air vehicle to make a flight;
- a rotor (3) that extends outwards from the body (2) and rotates about an axis in connection with the at least one engine (M);
- at least one shaft (4) extending outward from the rotor (3) and triggered by the at least one engine (M) to rotate about the axis at a rotational speed;
- at least two blades (5) connected with the at least one shaft (4) and triggered by the shaft (4) to move;
- at least one flap (501) on at least one of the at least two blades (5), which provides drag force to the rotor (3) by movement of the at least one flap, the at least one flap (501) having a closed position (C) in which the at least one flap (501) corresponds to an aerodynamic surface of the blade (5) and an open position (O) in which the at least one flap (501) moves linearly from the closed position (C) with movement of the rotor (3), extends out of the blade (5) and increases the drag force of the rotor (3);
- at least one brake which is located on the body (2) in connection with the rotor (3), and which enables the at least one flap (501) to move to the closed position (C) and/or the open position (O) so that a rotational speed of the rotor (3) is adjusted by a user;
- at least one element (7) which is triggered by the shaft (4) to move in correspondence with rotational movement of the blade (5) at a speed that is different from the rotational speed of the shaft (4);
- at least one flap mechanism (8) in which the at least one element (7) is located in connection with the shaft (4), and which enables the at least one flap (501) to move to the open position (O) and/or closed position (C), with respect to rotational movement of the at least one element (7) and movement of the rotor (3);
- at least one pin (9) located in the flap mechanism (8) in connection with the at least one brake, the at least one pin transmitting torque received from the brake to the shaft (4);
- and
- a table (10) located between the shaft (4) and the pin (9) for torque transfer, with one end connected to the shaft (4) and a second end to the pin (9), the at least one element (7) in connection with the table (10), which moves with free rotation to approach and move away from the pin (9) in order for the table (10) to rotate, and which is triggered by the shaft (4) to gradually reduce the rotational speed of the rotor (3) by causing the at least one flap (501) to come to the open position (O) and/or closed position (C).
