Document Type and Number:
Japanese Patent JP6669916
Kind Code:
B2
Abstract:
To provide a radio-controlled rotary-wing aircraft capable of efficiently and surely inspection work without receiving restriction of an inspection object.SOLUTION: A pair of left and right rotors 16A and 16B is provided at both left and right sides of an airframe 12. A drive part 18 rotates the pair of left and right rotors 16A and 16B. A first swing part 20 and a second swing part 22 for swinging the pair of left and right rotors 16A and 16B are accommodated in an upper rear part 1204 through a connection arm 26. When a straight line connecting the pair of rotors 16A and 16B is defined as a pitch axis A, the first swing part 20 integrally swings the pair of rotors 16A and 16B around the pitch axis A at a first angle θ centering on the pitch axis A. When a straight line orthogonal to a middle point between the pair of rotors 16A and 16B on the pitch axis A to connect front to back directions of the airframe 12 is defined as a roll axis B, the second swing part 22 integrally swings the pair of rotors 16A and 16B around the roll axis B at a second angle φ centering on the roll axis B.SELECTED DRAWING: Figure 1
