Title:
INDUSTRIAL UNMANNED HELICOPTER
Document Type and Number:
WIPO Patent Application WO/2019/167302
Kind Code:
A1
Abstract:
Provided is an industrial unmanned helicopter in which a wide load space can be ensured, in which the energy efficiency of coaxial contra-rotating rotors can be enhanced, and which provides a high degree of freedom in designing of the helicopter body. In order to solve the above problem, the industrial unmanned helicopter is provided with first and second main rotors that are contra-rotating around a non-rotary, hollow main mast. A first swash plate for changing the attack angle of rotor blades of the first main rotor and a first drive unit for tilting the first swash plate are disposed above the first main rotor. A second swash plate for changing the attack angle of rotor blades of the second main rotor and a second drive unit for tilting the second swash plate are disposed below the second main rotor. The main mast is formed such that a signal wire for controlling the first drive unit or the second drive unit can be inserted in the main mast.
