Vertical Take-Off and Landing Unmanned Aerial Vehicle

Vertical Take-Off and Landing (VTOL) Unmanned Aerial Vehicle

This technology features a structure that performs directional changes and attitude control for a tricopter-type VTOL UAV by applying a tilting mechanism to the tail propeller section. It utilizes a mechanical design where a tilting gear is engaged with a tail propeller mount, which is coupled to the center frame via bearings, allowing for rotational control via a servomotor.

Reduced energy efficiency and limited flight time of UAVs, as well as production process inefficiencies caused by the complexity of existing airframe structures.

This technology designs the tail propeller with a tiltable mount structure and uses a servomotor and tilting gear to adjust the angle of the tail propeller, enabling directional changes and stable flight attitude control. Additionally, the frame is designed using lightweight materials such as carbon fiber to optimize the airframe weight. Applicable to unmanned exploration, surveillance, and environmental monitoring, it improves energy efficiency and extends the flight time of the UAV.

Key Features:

• A tail propeller mount gear formed integrally with the tail propeller mount, configured to rotate around the center frame as a central axis, located below the tail propeller motor installation section where the tail propeller motor is mounted.
• A tilting gear installed to mesh with the teeth of the tail propeller mount gear, coupled to rotate the tail propeller mount gear left and right around the center frame as a central axis.
• In an unmanned aerial vehicle, a body in which the driving equipment for operating the unmanned aerial vehicle is installed.
• A tail propeller section that provides flight propulsion and is coupled to the frame section in a tiltable manner.
