Embodiment Construction

[0031] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] ginseng Figure 1 to Figure 5 As shown, the aircraft includes a frame 10, and a drive system 20 and a rotor 30 mounted on the frame.

[0033] The support 10 is a supporting platform, under which a landing gear, an aerial photography platform, etc. can be fixed, and above which, parts such as a power supply and a circuit board can be carried.

[0034] The bracket 10 includes a first side bar 11 and a second side bar 12 arranged in parallel, and the first...

Abstract

Disclosed is a variable-pitch flight unit, comprising: a support and a plurality of rotor blades mounted on the support; each rotor blade comprises a drive shaft, a first flap, a second flap, a hub and a drive part; the drive part comprises a first slider sleeved on the drive shaft and located below the hub; the drive part further comprises a power device capable of driving the first slider to rise; the power device comprises a second slider, a variable-pitch rocker arm, a connecting rod and a steering engine; a first connecting part and a second connecting part are symmetrically disposed at two sides of the second slider; and the variable-pitch rocker arm has a first branch arm rotatably connected to the first connecting part and a second branch arm rotatably connected to the second connecting part. The variable-pitch rocker arm of the present invention is a dual-thrust structure, such that the variable-pitch rocker arm applies symmetrical force on the second slider, extending the service life of the power device.

Description

technical field [0001] The application belongs to the field of aerial photography, and in particular relates to a variable-distance multi-axis aircraft. Background technique [0002] Each axis of the multi-axis aircraft in the existing technical solution is composed of a corresponding propeller and a motor driving the corresponding propeller. The attitude maintenance and maneuvering action of the aircraft flight is to control the speed of each motor separately through the flight control system (the rotation directions of the various motors of the existing multi-axis aircraft are in pairs to counteract the spin torque) to achieve the attitude and action control of the aircraft of. The attitude of the vertical take-off and landing aircraft includes level and tilt. Maneuvering actions include level flight, ascent, descent, and spin (around its own Z axis, that is, the vertical axis of the horizontal plane of the body structure). The ascent and descent actions of the multi-ax...
