Embodiment Construction

[0008] Now in conjunction with accompanying drawing, the present invention is described in detail: a kind of composite rotorcraft, comprises fuselage 1, left wing 21, left rotor 31, left shaft 41, right wing 22, right rotor 32, right shaft 42, propeller 5, empennage 6 and landing gear 7. Propeller 5 adopts ducted fan as propulsion device, uses motor as power, and adopts lithium battery to supply power. The left wing 21 and the right wing 22 have the same structure, and they are symmetrically installed on the left and right sides of the fuselage 1 . The left-hand rotor 31 and the right-hand rotor 32 have the same size, and the steering is opposite. One is left-handed, and the other is right-handed. The left shaft 41 and the right shaft 42 are symmetrically fixed below the middle of the left wing 21 and the right wing 22 respectively. The left rotor 31 is connected with the left shaft 41 through a bearing, and the right rotor 32 is connected with the right shaft 42 through a b...

Abstract

The invention discloses a compound type rotorcraft, which belongs to the technical field of aircrafts. The compound type rotorcraft comprises a fuselage, a left wing, a left rotor wing, a left shaft, a right wing, a right rotor wing, a right shaft, a thruster, an empennage and an undercarriage, wherein the left wing is identical with the right wing in structure; the left wing and the right wing are symmetrically arranged on the left side and the right side of the fuselage; the left rotor wing and the right rotor wing are identical in size and are opposite in rotating direction; the left rotor wing is arranged below the middle part of the left wing through a bearing and the left shaft; the right rotor wing is arranged below the middle part of the right wing through a bearing and the right shaft; the leading edge of the left wing is higher than the trailing edge of the left wing; an included angle between the rotating plane of the left rotor wing and the plane of the left wing is greater than 10 degrees; an included angle between the left wing and a horizontal plane is between 15 degrees and 30 degrees; an included angle between the rotating plane of the left rotor wing and the horizontal plane is 5 degrees and 15 degrees; the leading edge of the left wing is before the most front end of a rotating circle of the tip of the left rotor wing; the trailing edge of the left wing is behind the rearmost end of the rotating circle of the tip of the left rotor wing; the compound type rotorcraft is relatively stable and safe in flying.

Description

technical field [0001] A compound rotorcraft belongs to the technical field of aircraft, in particular to a rotorcraft. Background technique [0002] The traditional gyroplane has only one main rotor to generate lift, so the safety and stability are not high. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiency of traditional rotorcraft, invent a kind of safe and stable composite rotorcraft that can glide for a long distance. [0004] A composite rotorcraft comprises a fuselage, a left wing, a left rotor, a left shaft, a right wing, a right rotor, a right shaft, a propeller, an empennage and a landing gear. The fuselage is equipped with a control system and airborne equipment. The propeller uses a ducted fan as the propulsion device, uses a motor as power, and uses a lithium battery or an aluminum battery for power supply. The left wing and the right wing have the same structure, and they are symmetrically...
