Problems solved by technology

This structure has the following disadvantages, that is, each propeller of the multi-axis multi-rotor aircraft needs to consume a lot of electric energy to control the motion state of the aircraft, and the long-term effective endurance requires the battery to store enough electric energy, which increases the The aircraft's own weight and manufacturing cost, and due to the limited service life of the battery, the stored electric energy is also limited, so it is difficult to meet the requirements of long-term battery life

Embodiment Construction

[0012] Such as figure 1 Shown is a structural diagram of a belt-driven four-rotor aircraft transmission system of the present invention, which is mainly composed of a rotor assembly 1, a guide wheel 2, and an input shaft gear 3. The input shaft gear 3 belongs to a part in the power distribution transmission system, and the gear is directly driven by the oil-driven engine or is driven by a gear installed on the output shaft of the oil-driven engine through meshing with the input shaft gear 3 .

[0013] The power distribution transmission system extends four brackets outward, and the brackets are evenly spaced to form a cross shape, etc., and the front ends of each bracket are equipped with a rotor assembly 1 that can change the rotor pitch.

[0014] In this structure, the power distribution transmission system is cross-shaped by the bracket extending outward from the input shaft gear 3, in which there are two symmetrical rotor assemblies that are driven by the driven gear and d...

Abstract

The invention relates to a belt-transmission four-rotor-wing aircraft. The belt-transmission four-rotor-wing aircraft is provided with an engine, a main rack, a power distribution and transmission system and a flight control system, wherein a plurality of brackets are outwards extended from the power distribution and transmission system and are uniformly spaced to form cross shapes and the like, and rotor wing assemblies with changeable propeller pitches are arranged at the front ends of the brackets and comprise rotor wing rotation driving components and rotor wing propeller pitch changing components. According to the belt-transmission four-rotor-wing aircraft, four shafts and four rotor wings are driven by the engine, and the size of rising power of all the shafts is changed through changing the propeller pitches of all the rotor wings, so as to realize the change of the flight attitude of the aircraft; the fuel-driven engine is adopted, so that the effective payload is increased, and the flight time is prolonged, thus the gear-transmission four-rotor-wing aircraft is particularly applicable to long-time and long-distance operation.

Description

technical field [0001] The invention belongs to the technical field of aviation products and relates to a multi-axis and multi-rotor aircraft. Background technique [0002] The multi-axis multi-rotor aircraft is operated and controlled by the radio remote control system and the autonomous flight control system to realize the aircraft's take-off and landing, forward and backward flight, acceleration and deceleration, and direction control. Maneuverability, stability, effective mission load and endurance time are important indicators for investigating multi-axis and multi-rotor aircraft. Under the same maneuverability and stability conditions, users pursue greater effective mission load and long-term endurance flight ability. [0003] In traditional multi-axis multi-rotor aircraft, motors are installed on the rotating shafts where the propellers are located to drive the propellers to achieve the purpose of flight. By changing the rotation speed of the motors, the lift force o...
