Description

Technical Field

[0001] The invention relates to a powered rotor of an aircraft, belonging to the technical field of aircraft. Background Art

[0002] The rotors of existing heavy-load aircraft are all propellers. Due to their narrow blades, the lift they provide is not large. Generally, very long blades are required to rotate at high speed to generate sufficient lift. The outer linear speed of the blades is very high, the resistance and noise are very large, and the efficiency is not high.

[0003] There are many research directions in the prior art, such as CN202411007689.0 discloses a non-rotationally symmetrical propeller, a powered rotor, and an aircraft. Another example: CN202411470400.9 discloses a shaftless magnetic levitation rotor power system and an aircraft. These technical solutions solve the power problem from different directions, however, there are no relevant reports on technical solutions to solve the problem from the powered rotor itself. Summary of the invention

[0004] The purpose of the present invention is to provide a more efficient aircraft power rotor starting from the design of the power rotor itself.

[0005] To achieve the above purpose, the technical means adopted by the present invention are: a powered rotor of an aircraft, which is composed of at least two half-glider wings evenly distributed along the circumference, the rotor is connected to a rotor hub, and the rotor hub is rotationally connected to the output shaft of a power motor.

[0006] Furthermore, the two half-gliders are arranged in a central circular array around the rotor hub.

[0007] Furthermore, a ventilation pipeline is arranged in the wing body of the half hang glider, and a centrifugal fan is arranged in the rotor center to form a centrifugal air duct, which is respectively connected to the ventilation pipelines of the two half hang gliders. The output shaft of the power motor drives the centrifugal fan to rotate, and the high-speed airflow generated by the centrifugal fan passes through the centrifugal air duct of the rotor center and is ejected through the ventilation pipelines of the two half hang gliders.

[0008] Furthermore, an arc-shaped wingtip is arranged on the end face of the air outlet end of the half hang glider, and the arc of the wingtip gradually increases from the air outlet side of the ventilation duct of the half hang glider to the other side of the half hang glider, and an arc-shaped air path duct is arranged in the wingtip, the air inlet end of the arc-shaped air path duct is connected with the air outlet of the ventilation duct of the half hang glider, and the air outlet opening at the other end faces the side away from the rotor center and opposite to the tangent of the rotation direction, so that the airflow ejected from the ventilation duct is ejected along the arc-shaped air path duct in the wingtip to the side opposite to the tangent of the rotation direction of the rotor.

[0009] Furthermore, the aperture of the air outlet opening of the arc-shaped air path pipe is larger than the aperture of the air inlet end.

[0010] Furthermore, a wing tip is arranged at the outer end of the half glider, and a high-speed axial flow fan is installed on the wing tip to generate wing tip thrust to drive the rotor to rotate.

[0011] Compared with the prior art, the beneficial technical effects of the present invention are: 1. The structure is simple. A relatively wide and thick glider wing is used as the rotor to generate a large lift. The high-speed airflow generated by the more efficient centrifugal fan generates centrifugal force through the rotation of the rotor. The high-speed airflow is ejected through the wing tip. The power arm relative to the rotor center axis has been maximized. Only a small thrust is needed to drive the rotor to rotate, and the overall efficiency is high. 2. As the hang glider has a large width, the rotation speed does not need to be very high when used as a rotor, the noise generated is small, and the load capacity is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0013] Figure 1 A schematic cross-sectional view of the structure of Embodiment 1 of the present invention; Figure 2 A schematic structural diagram of embodiment 1 of the present invention.

[0014] In the figure: 1. power motor, 2. motor flange bracket, 3. rotor center, 4. glider, 5. wing tip, 6. centrifugal fan, 7. ventilation pipeline, 111. arc-shaped air pipeline, 222. central pipeline. DETAILED DESCRIPTION Example

[0015] like Figure 1 , 2 The power rotor of the aircraft shown is composed of two half-gliders 4 symmetrically distributed along the circumference at 180 degrees. The rotor is connected to the rotor hub 3, and the rotor hub 3 is rotationally connected to the output shaft of the power motor 1 through the motor flange bracket 2.

[0016] A centrifugal fan 6 is installed in the rotating hub 3, a centrifugal air duct is formed in the rotor hub 3, a ventilation pipeline 7 is arranged in the wing body of the hang glider 4, and the centrifugal channel is respectively connected with the ventilation pipelines 7 of the two half hang gliders 4 through the central pipeline 222, and an arc-shaped wing tip 5 is arranged on the end face of the air outlet end of the half hang glider 4, and the arc of the wing tip 5 gradually increases from the air outlet side of the ventilation pipeline 7 of the half hang glider 4 to the other side of the half hang glider 4, and an arc-shaped air path pipeline 111 is arranged in the wing tip 5, and the air inlet end of the arc-shaped air path pipeline 111 is connected with the air outlet of the ventilation pipeline 7 of the half hang glider 4, and the air outlet opening at the other end faces the other side of the half hang glider 4.

[0017] The diameter of the air outlet opening of the arc-shaped air path pipe 111 is larger than the diameter of the air inlet end.

[0018] The output shaft of the power motor 1 drives the centrifugal fan 6 to rotate. The high-speed airflow generated by the centrifugal fan 6 passes through the centrifugal air duct of the rotor hub 3 and respectively passes through the ventilation pipes 7 of the two half-gliders 4. The airflow ejected from the ventilation pipe 7 is ejected along the arc-shaped air path 111 in the wing tip 5 to the other side of the half-glider. The air outlet openings of the two wing tips are opposite to the tangent of the rotor rotation direction. The high-speed airflow generated by the centrifugal fan drives the gliders arranged in a circular array to rotate, thereby generating lift.

[0019] A relatively wide and thick hang glider is used as the rotor to generate a greater lift, and a more efficient centrifugal fan is used to generate power. Even if there is pipe resistance in the process of passing through the rotor, the high-speed airflow is offset by the centrifugal force generated by the rotation of the rotor. The high-speed airflow is ejected from the rear of the wing tip. The power arm relative to the rotor center axis is maximized, and only a small thrust is needed to drive the rotor to rotate. In addition, the impeller diameter of the centrifugal fan does not need to be very large, and the motor speed can be very high, and the overall efficiency will be further improved. In addition, since the hang glider has a large width, the rotor itself does not need to rotate at a very high speed, so the noise generated is not large, but the load can be very high. Example

[0020] A powered rotor of an aircraft, which is composed of a plurality of (may be 3 or 5) half-glider wings evenly distributed along a circumference, the rotors are connected to a rotor hub, the rotor hub is rotationally connected to an output shaft of a power motor, wing tips are arranged at the outer ends of the half-glider wings, and high-speed axial flow fans are installed on the wing tips to generate wing tip thrust to drive the rotor to rotate.

[0021] The above embodiments are used to illustrate the technical solution of the present invention and cannot be used as a limitation of the technical solution of the present invention. All simple improvements based on the technical solution of the present invention should be regarded as within the protection scope of the present invention.
