Incongruent six-propeller helicopter

Abstract

The invention relates to an incongruent six-propeller helicopter provided with four same fixed-pitch propellers with horizontal rotating surfaces, the connecting lines of the rotating centers of the four fixed-pitch propellers are square or rectangular, and the center of the square or rectangular is located on the gravity center of a helicopter body or slightly behind the gravity center. A centralpropeller with a horizontal rotating surface is arranged above the gravity center of the top of the helicopter body, the rotating center of the central propeller is located on the gravity center of the helicopter body or slightly behind the gravity center, and a tail fixed-pitch propeller with the rotating surface perpendicular to or approximately perpendicular to the rotating surface of the central propeller is arranged at the tail of the helicopter body. An undercarriage is arranged below the helicopter body near the gravity center; The size of the central propeller and the power of an engine for driving the central propeller are the maximum, the central propeller provides most of lift force, the four fixed-pitch propellers with the same horizontal rotating surfaces provide a small partof lift force and are responsible for controlling pitching, rolling and heading, and the tail fixed-pitch propeller cooperatively controls heading, so that the unmanned aerial vehicle has the advantages of long endurance time and high carrying capacity. The incongruent six-propeller helicopter can be applied to transportation, aerial photography, agricultural operation and the like.

Description

technical field [0001] The invention relates to an incomplete six-propeller helicopter capable of vertical lifting, hovering, front-back, left-right, and left-right flight independent of airports. Background technique [0002] At present, the known successful method of helicopters that can realize vertical lift, front and rear, left and right flight, and hovering has six-propeller helicopters, which have the advantages of simple structure and high reliability, but six-propeller helicopters use six identical, pitch Smaller fixed-pitch propellers have a small load capacity and poor wind resistance. Contents of the invention [0003] In order to improve the load capacity and wind resistance of the six-screw helicopter, the invention provides an incongruent six-screw helicopter to achieve this goal. [0004] The technical solution adopted by the present invention to solve its technical problems is: the fuselage left front, right front, left rear and right rear respectively ar...
