Hybrid power composite unmanned helicopter

Abstract

The invention relates to a hybrid power composite unmanned helicopter. The hybrid power composite unmanned helicopter comprises a helicopter body and further comprises an undercarriage component fixedat the lower part of the helicopter body, stub wing components symmetrically distributed on the two sides of the helicopter body, a main propeller component at the middle part of the helicopter body,and a tail rotor component at the rear part of the helicopter body, the undercarriage component comprises an undercarriage body and a dismountable ground wheel connected with the lower part of the undercarriage body through a bolt, the stub wing component comprises a stub wing body, a pushing propeller at the middle part of the stub wing body, and a pushing motor distributed in the stub wing body, the main propeller component comprises a main propeller main body rotatably connected with the upper part of the helicopter body, an engine distributed at the front part of the inner part of the helicopter body and an auxiliary generator arranged at the front part of the engine, the tail rotor component comprises a tail rotor main body arranged at the tail end of the helicopter body and a tail rotor motor arranged at the inner part of the tail end of the helicopter body, the invention provides the hybrid power composite unmanned helicopter, and a stub wing can be rapidly dismounted.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a hybrid power composite unmanned helicopter. Background technique [0002] Rotary-wing UAVs and fixed-wing UAVs have their own advantages and disadvantages. Fixed-wing has a longer flight distance and a greater payload. The helicopter-style rotor has superior flexibility, allowing the drone to take off and land in a small space. The power transmission system of a helicopter is the most complicated set in the existing manned aircraft. The main rotor is driven by the engine through the gearbox, and the rear tail rotor is driven by the transmission shaft. This kind of power structure is relatively complicated. The tail rotor of the helicopter is easy to collide with objects such as treetops and high-voltage lines during low-altitude steering, resulting in irreparable consequences. Once the tail rotor breaks, the helicopter will completely lose contro...

AI Technical Summary

Problems solved by technology

The main rotor is driven by the engine through the gearbox, and the rear tail rotor is driven by the transmission shaft. This kind of power structure is relatively complicated.

The tail rotor of the helicopter is likely to collide with objects such as treetops and high-voltage lines during low-altitude steering, resulting in irreparable consequences. Once the tail rotor breaks, the helicopter will completely lose control

In addition, the huge rotor of the helicopter is also a place prone to accidents. The huge main rotor rotates rapidly. If it hits an obstacle, it will cause destructive damage to the drone.
