Ducted rotor flying crane with traction and energy transmission and its control method

Abstract

The flying hanger of the present invention is a ducted rotorcraft mainly for lifting heavy objects. The aerodynamic structure bears the main lift centered on the coaxial forward and reverse dual-rotors of the large-diameter main duct. The variable inertia device is set in the rotor system, so that it can produce differential variable inertia to induce gyroscopic fixed axis, and has the ability to resist turbulence and transition wind. Multiple small-diameter ducted rotor bodies are arranged outside the multi-ring main duct, and the connecting arms can perform telescopic, torsional, and swinging four-degree-of-freedom movements, which serve as auxiliary lift and direction attitude control and anti-vortex rings. The lower end of the main duct is provided with side nozzles around the main nozzle, and the built-in swing wind deflector adjusts the direction and the active anti-vortex ring. The active anti-vortex ring of the plasma energy wave generator and the improved Reynolds number are also set up. The flying crane is a wireless remote control driven by wired traction power or fuel and its own energy power machine. It has anti-wind and large lifting capacity, and can work continuously under harsh environmental and climatic conditions.

Description

[technical field] [0001] Utilize the lift of the ducted rotor aerodynamic force as the vertical take-off and landing power for the flight equipment required for lifting, lifting, and handling operations in some fields. [Background technique] [0002] In the field of conventional lifting operations, all kinds of lifting equipment composed of traditional hydraulic truss structure system and movable and fixed pulleys are used. In some areas, many lifting operations are beyond the working range of traditional crane jibs. For example: sea, land, and air long-distance suspended cargo and life-saving operations, etc., generally use large helicopters for long-distance suspended aerial operations. However, there are many restrictions on using a helicopter, and it is very dangerous because the large rotor is not easy to operate in a narrow space. The ability to resist crosswinds, headwinds, and turbulent transitional winds is very limited. It is not easy to hover at low altitude fo...

AI Technical Summary

Problems solved by technology

There is no similar rotorcraft that separates the main lift and propulsion aerodynamic structures, and there is no perfect technical method and equipment for actively resisting, interfering, and preventing the eradication of the aerodynamic structure of the vortex ring without avoiding the precursor vortex ring gas field induced by itself
