Abstract

The invention provides a multi-axis coaxial dual-blade multi-rotor UAV, which includes: a frame cockpit, a pluggable arm, a landing gear, a propeller protection device, a power device and an electronic control system. The circular array of eight pluggable arms is located on the horizontal plane of the cockpit. The end of each arm is connected to two coaxial brushless motors through a motor base with an installation angle, driving the two propellers to rotate in opposite directions. The landing gear is a pair of steel structure landing gear, and the propeller protection device is a hollow cone installed under the lower motor. The technology of the present invention can be applied to manned multi-rotor or large-load multi-rotor unmanned aerial vehicles, not only simple in structure, low in manufacturing cost, but also has the advantages of small size, easy transportation, heavy load, anti-rollover, and strong redundancy. If the motor propeller fails, it can still fly normally, ensuring the safety of the multi-axis coaxial double-propeller multi-rotor UAV and passengers.

Description

technical field [0001] The invention relates to a manned unmanned aerial vehicle, in particular to a multi-axis coaxial double-propeller multi-rotor unmanned aerial vehicle. Background technique [0002] In recent years, with the rapid development of motor technology, battery technology and new material technology, multi-rotor UAVs continue to develop in the direction of large load, long endurance, safety and intelligence. Large-load multi-rotor UAVs are even manned The design and development of multi-rotor UAVs became possible. Manned multi-rotor UAVs can be used in tourism and entertainment, emergency medical services, firefighting, express logistics, power grid maintenance, pipeline inspection, pesticide spraying and other scenarios; as well as offshore personnel and material transportation, maritime operations and other military warfare scenarios. [0003] At present, manned multi-rotor UAVs and heavy-duty multi-rotor UAVs have problems such as large size, large aerodyn...
