Problems solved by technology

However, due to the limitation of battery energy density, its flight time is generally only 10-30 minutes, and the way of increasing its flight time by simply increasing the number of batteries will greatly reduce its load capacity
Therefore, compared with oil-powered helicopters, the biggest problem with electric multi-rotors (including electric helicopters) is poor endurance performance

Abstract

The invention discloses a variable-pitch coaxial oil-driven six-rotor helicopter. The variable-pitch coaxial oil-driven six-rotor helicopter comprises a coaxial rotor-operating system, a power system-transmission system and a frame system, wherein the coaxial rotor-operating system and the power system-transmission system are mounted on the frame system. According to the invention, problems of the low load, short endurance, poor wind resistance and the like in the traditional electric multi-rotor helicopter are mainly solved; and problems of high purchase, use and maintenance cost, high use and maintenance technical threshold and the like caused by complicated mechanical structure, structural dynamic characteristic, flight dynamical characteristic, aerodynamic characteristics and flight control system in the traditional helicopter are also solved.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to an oil-powered variable-pitch coaxial six-rotor helicopter. technical background [0002] Common vertical take-off and landing drones mainly include oil-powered helicopters (such as figure 1 shown), electric helicopters (such as figure 2 shown) and electric multi-rotor helicopters (such as Figure 4 shown) and other types. [0003] Such as figure 1 and figure 2 Conventional helicopters can be divided into oil-powered helicopters and electric helicopters according to different power systems. Their mechanical systems mainly include power subsystems, transmission subsystems, control subsystems, and rotor subsystems. control subsystem. The transmission subsystem usually includes complex closed gear trains and sealing devices, the structure is complex, the manufacturing cost is high, and the assembly process requires high requirements. The most important part of the steerin...
