Problems solved by technology

[0002] For the current rotorcraft, it is generally divided into single-rotor, multi-rotor, ducted rotor and other aircraft. All kinds of aircraft have their own characteristics. For example, single-rotor generally has a large load and high efficiency. Multi-rotor control is flexible and sensitive. Ducted rotors are safe and reliable, less affected by turbulence, but these rotorcraft have their own obvious defects, such as single rotors are not flexible, prone to failure when disturbed, multi-rotors are inefficient, and cannot be applied to large loads and In the long-endurance environment, it is difficult to control the ducted aircraft, and the flight is in a static and unstable state, which is prone to failure

Abstract

The invention relates to a composite rotor craft. The composite rotor craft comprises a craft main body, an energy device, a plug-in connector and a control device, wherein the craft main body comprises a main propeller and a plurality of auxiliary propellers; the main propeller comprises a main rotor I, a main rotor II and a main duct; the main rotor I and the main rotor II are fixed in the main duct through a main duct supporting frame; the part, in the main duct, of the outer edge of the main duct supporting frame is provided with a plurality of vertical connecting rods; cantilevers are outward and horizontally arranged at the bottoms of all the vertical connecting rods; the auxiliary propellers are arranged at the outer ends of all the cantilevers. The composite rotor craft has the benefits that the integration of various rotor flight modes is adopted, the flight efficiency is greatly improved, the flexibility of the craft is greatly improved, and the flight stability and reliability are also greatly improved; an advanced flight control mode is adopted, a plurality of rotors can be simultaneously controlled and adjusted, the control difficulty of the craft is greatly reduced, and the flight efficiency of the craft is improved.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a composite rotorcraft. Background technique [0002] For the current rotorcraft, it is generally divided into single-rotor, multi-rotor, ducted rotor and other aircraft. All kinds of aircraft have their own characteristics. For example, single-rotor generally has a large load and high efficiency. Multi-rotor control is flexible and sensitive. Ducted rotors are safe and reliable, less affected by turbulence, but these rotorcraft have their own obvious defects, such as single rotors are not flexible, prone to failure when disturbed, multi-rotors are inefficient, and cannot be applied to large loads and In the long-endurance environment, it is difficult to control the ducted aircraft, and the flight is in a static and unstable state, which is prone to failure. Contents of the invention [0003] The purpose of the present invention is to provide a compound rotorcraft to overcome the above...
