Title:
AIRFLOW JET-TYPE STEERING UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/103497
Kind Code:
A1
Abstract:
Disclosed is an airflow jet-type steering unmanned aerial vehicle. The airflow jet-type steering unmanned aerial vehicle comprises an unmanned aerial vehicle body (1) of a multi-rotor-wing unmanned aerial vehicle; a flight control module is arranged in the unmanned aerial vehicle body (1); a propelling duct (3) is arranged directly below the gravity center of the bottom of the unmanned aerial vehicle body (1); the diameter of the front end of the propelling duct (3) is larger than the diameter of the rear end of the propelling duct (3), and the inner diameter of the propelling duct is in smooth transition; a front duct electric motor (4) and a rear duct electric motor (5) are arranged at the front end and the rear end in the propelling duct (3) respectively, the front duct electric motor (4) and the rear duct electric motor (5) rotate reversely, and the front duct electric motor (4) and the rear duct electric motor (5) are both provided with impellers (6); a rotary shaft (7) is arranged between the propelling duct (3) and the bottom of the unmanned aerial vehicle body (1); a steering electric motor (8) for driving the rotary shaft (7) and a steering reduction gearbox (9) are arranged at the bottom of the unmanned aerial vehicle body (1); and the front duct electric motor (4), the rear duct electric motor (5) and the steering electric motor (8) are all electrically connected with the flight control module. According to the unmanned aerial vehicle, advancing and steering control, which is different from rotor wing power adjustment, over the multi-rotor-wing unmanned aerial vehicle is achieved by additionally arranging the propelling duct, and the flight speed of the unmanned aerial vehicle is increased.
