Asymmetric double axle helicopter and flying method thereof

Abstract

The invention aims at providing an asymmetric double axle helicopter with small volume, compact structure and good performance and a flying method thereof. The asymmetric double axle helicopter comprises a helicopter body, a first power output shaft and a second power output shaft; the first power output shaft and the second power output shaft are both mounted in the helicopter body in a matched manner; the first power output shaft is arranged in the vertical direction of the helicopter body; the second power output shaft is arranged in a direction having a certain angle with the vertical lineof the helicopter body; the first power output shaft and the second power output shaft synchronously rotate; the asymmetric double axle helicopter further comprises two groups of rotors; the two groups of rotors are correspondingly mounted on the first power output shaft and the second power output shaft in a matched manner; the two groups of rotors do not collide with the first power output shaft and the second power output shaft in the rotating process; and operating levers are connected to blades of the rotors. The asymmetric double axle helicopter and the flying method thereof are appliedto the technical field of double axle helicopters.

Description

technical field [0001] The invention relates to a biaxial helicopter and its flying method, in particular to an asymmetrical biaxial helicopter and its flying method. Background technique [0002] Common two-axis helicopters include vertical two-axis type and parallel two-axis type. However, these two types of two-axis helicopters need to be designed to be larger in order to avoid rotors colliding with each other. Therefore, a side-by-side symmetrical two-axis helicopter has appeared. This helicopter uses synchronous rotation of the rotors to prevent the rotors from colliding with each other. However, due to the symmetrical design, the lift generated by the rotation of the rotors is not on the same axis. Therefore, some The lift forces cancel each other out, resulting in a loss in power. Contents of the invention [0003] The technical problem to be solved by the invention is to overcome the deficiencies of the prior art, and provide an asymmetric two-axis helicopter with...

[0002] The common two-axis helicopters are vertical two-axis type and parallel two-axis type. However, in order to avoid the rotor collision of these two types of two-axis helicopters, it is necessary to design a larger volume.

Therefore, a side-by-side symmetrical two-axis helicopter has appeared. This helicopter uses synchronous rotation of the rotors to prevent the rotors from colliding with each other.
