Problems solved by technology

This type of swash plate system requires that the steering gears participating in the action must be coordinated and deflected in real time to achieve flight control of the aircraft. If any of the steering gears involved in the action fails or the control is inaccurate, the aircraft may lose control

Embodiment 1

[0079] Such as figure 1 , shows a structural diagram of an unmanned helicopter that uses auxiliary lift-anti-torque-cooling function device to cool the engine and adopts 4-channel hybrid control swash plate, which is characterized in that it includes main rotor head 1, main rotor 2, swash plate Device 3, reduction box 4, starting device 5, at least one auxiliary lift-anti-torque-cooling function device 6, engine 7, exhaust pipe 8, landing gear 9, tail rotor 10, tail pipe 11, tail rotor device 12 and machine body frame13. The main rotor head 1 is installed above the reduction box 4; the main rotor 2 is installed at both ends of the main rotor head; the 4-channel swash plate control device 3 is installed below the main rotor head, fixed at The top of the box; the starting device 5 is installed on the front of the fuselage frame 13, above the engine 7; the engine 7 is installed on the front of the fuselage frame by suspension, and the landing gear 9 is installed on the machine ...

Embodiment 2

[0100] The structure of embodiment 2 is basically the same as that of embodiment 1, the difference is that there are two auxiliary lift-anti-torque-cooling functional devices, and the two ducts are symmetrically arranged on both sides of the central axis of the unmanned helicopter to ensure that there is no The stability of the roll control of the manned helicopter and the ease of arranging the center of gravity of the unmanned helicopter, the engine drives its rotation through the transmission parts, keeping the rotation direction of all the lift fans opposite to the rotation direction of the main rotor. The engine drives the lift fan to rotate through the transmission part. The transmission part can be any one of transmission belts, gears and shafts. The structure of the auxiliary lift-anti-torque-cooling function device is as follows: Figure 10 shown.

Embodiment 3

[0102] The structure of embodiment 3 is basically the same as that of the first two embodiments, the difference is that: the four steering gears of the 4-channel hybrid control swashplate are symmetrically distributed to a point on the main shaft axis of the main rotor;

[0103] Taking the forward direction of the unmanned helicopter as the central axis, the line connecting the installation positions of the first steering gear and the fourth steering gear forms an angle of 45 degrees with the central axis, and the connection line between the installation positions of the second steering gear and the third steering gear and the central axis At a 45-degree angle [the first and second steering gears are close to the nose; the third and fourth steering gears are close to the tail]; The connection line of the position and the central axis form an angle of 0 degrees, and the connection line of the installation position of the second servo and the third servo forms an angle of 90 degr...

Abstract

The invention discloses a pilotless helicopter, comprising a main rotor system, a swash plate device, a drive system, a starting device, an engine, a body frame, a tail rotor device, a landing device and at least one auxiliary lift, anti-twisting force and cooling functional device, wherein the auxiliary lift, anti-twisting force and cooling functional device comprises ducts and a lift fan, the lift fan is annularly embraced in the ducts, and the ducts are arranged symmetrical about a central axis which is the advancing direction of the pilotless helicopter; the ducts are fixed above the engine, and an air guide passage is designed below the ducts and guides air to a cylinder of the engine; and the swash plate device is a four-channel hybrid control swash plate device. A part of additional lift and anti-twisting force are provided for the pilotless helicopter by using the power of the cooling engine, so that the pilotless helicopter has larger effective load and higher efficiency. Four steering engines of the four-channel hybrid control swash plate device are arranged in a manner of backing up each other, so that the stability is improved.

Description

technical field [0001] The invention relates to an unmanned helicopter. Background technique [0002] Due to the advantages of low cost, easy maintenance, and good mobility, small UAVs have played a pivotal role in many fields such as natural disaster monitoring and rescue, border patrol and control, exploration, power system line inspection, etc. effect. In recent years, especially as the latest development and cutting-edge technology of modern agricultural plant protection technology, drone low-altitude pesticide application technology has broad prospects for development. Unmanned helicopter is a complex system with high technical requirements, high reliability requirements and difficult operation. When using unmanned helicopters for aerial photography, surveying and mapping, investigation, plant protection and pesticide application, the operation effect is obviously affected by various factors, which puts forward high requirements on the operation platform. The magnitu...
