Problems solved by technology

Harsh noise is not convenient for drones to perform various tasks, such as venue shooting, wedding shooting, logistics express, military and police detectives, etc.
[0006] Time has proved that relying solely on the shape of the propeller cannot solve the above problems. Although the use of ducts can solve the tip vortex, increase lift, and reduce noise, the effect is minimal.

Embodiment Construction

[0032] The motor is provided with a stator (19), two sets of upper and lower stator coils, and two upper and lower rotors (8), (9), and the rotor is an outer rotor. The center of the stator (19) of the motor is provided with a stator shaft (14), and the stator shaft (14) is hollow. The head end of the stator shaft (14) passes through the upper and lower rotors (8), (9) and is exposed outside the motor. The purpose of the exposure is to fix the fixed plate (16) of the unmanned flying saucer and directly or indirectly suspend the third party. Equipment, third-party equipment such as cameras, air filters, lamps, speakers, etc., the power lines (18) of the two sets of stator (19) coils pass through the stator shaft (14).

[0033]The unmanned flying saucer uses the upper and lower centrifugal fan blades (2), (10) instead of the propeller as the flight power, the upper and lower centrifugal fan blades (2), (10) are circular, and the upper centrifugal fan blade (2) The diameter is g...

Abstract

Disclosed are an unmanned flying saucer, upper centrifugal fan blades thereof and a motor thereof. The unmanned flying saucer replace a propeller with two centrifugal fan blades (2) and (10) as flyingpower, which are fixed onto an upper rotor (8) and a lower rotor (9) of the motor; an air inlet (3) of the unmanned flying saucer is arranged on the upper centrifugal fan blade (2); a round slot, serving as an air outlet (6), is formed between the edges of the upper centrifugal fan blade (2) and the lower centrifugal fan blade which (10) are assembled in a fastened mode; a steering wheel (4) is arranged under the lower centrifugal fan blade (6) and controlled by a steering engine (12) to adjust the width of a round slot of the air outlet (6); the motor is provided with a stator (19), an upperset of stator coil, a lower set of stator coil, the upper rotor (8) and the lower rotor (9), the center of the stator (19) is provided with a stator shaft (14), the head ends of the stator shaft (14)penetrate through the upper rotor (8) and the lower rotor (9) and are exposed out of the motor, and the stator shaft (14) is hollow.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to an unmanned flying saucer and its upper centrifugal fan blade and motor. Background technique [0002] There are roughly the following types of aircraft with vertical take-off and landing and hovering functions: multi-rotor rotorcraft, helicopters, tilt rotor aircraft, etc., but these aircraft have disadvantages such as low efficiency, unstable flight, and loud noise. [0003] Efficiency is low, and above-mentioned aircraft utilizes motor to drive the rotation of propeller as power flight. When flying, there is a difference in air pressure between the top and bottom of the propeller. Under the action of the pressure difference, the airflow naturally flows from the direction of high pressure to the direction of low pressure, so part of the airflow below the propeller will flow from the tip of the propeller to the top of the propeller. Thus forming the blade tip vortex. This vortex d...
