Problems solved by technology
[0003] In order to overcome the problem that when the multi-rotor helicopter flies forward horizontally, the downwash airflow of the two front rotors affects the flight of the two rear rotors, and the hexagonal layout occupies the same length vertically and horizontally, and occupies a large area. To provide a twin beam transverse multi-rotor helicopter to achieve this goal

Embodiment Construction
[0032] figure 1 In the shown embodiment, the first beam (7) is set in front of the center of gravity (P) on the top of the fuselage (9), the second beam (8) is set at the rear of the fuselage (9), and the center of gravity (P) is near the center of gravity (P) under the fuselage (9). Set the landing gear (10).
[0033] On the left side of the first crossbeam (7) close to the longitudinal direction of the fuselage, the first rotor (1) on the left side of the first crossbeam (1) is arranged, and on the left side of the first crossbeam (7) away from the longitudinal direction of the fuselage, that is, the first rotor (1) on the left side of the first crossbeam ) to the left of the first crossbeam (2) on the left; on the right side of the first crossbeam (7) close to the longitudinal direction of the fuselage, the first rotor (3) on the right side of the first crossbeam (3) is set, and on the right side of the first crossbeam (7) away from In the longitudinal direction of the fus...

A double-cross-beam side-by-side multi-rotor helicopter adopts six rotors; each rotor is driven by a respective engine or a respective motor and is correspondingly arranged on two transverse cross beams of a helicopter body; four rotors are arranged on the first cross beam; two rotors are on the left side of the longitudinal direction of the helicopter body; and the two rotors are on the right side of the longitudinal direction of the helicopter body. Two rotors are arranged on the second cross beam; one rotor is on the left side of the longitudinal direction of the helicopter body; and the other rotor is on the right side of the longitudinal direction of the helicopter body. The two rotors on the second cross beam are close to the longitudinal direction of the helicopter body; four rotors on the first cross beam are far away from the longitudinal direction of the helicopter body; the four rotors on the first cross beam have no rotor after being respectively parallel to the longitudinal line of the helicopter body; the two rotors on the second cross beam have no rotor before being respectively parallel to the longitudinal line of the helicopter body; when the double-cross-beam side-by-side multi-rotor helicopter horizontally flies forwards, downwash flows of the six rotors are independent of each other and are not affected by each other so that the flying stability and the flying efficiency are enhanced; a landing gear is arranged near the gravity center of the double-cross-beam side-by-side multi-rotor helicopter and at the bottom of the helicopter body; and the double-cross-beam side-by-side multi-rotor helicopter can be applied to aerial photography, pesticide application, fertilizer application and so on.
Description
technical field [0001] The invention relates to a helicopter that uses multi-rotors to vertically lift, hover, and fly forward, backward, left, and right without relying on an airport. Background technique [0002] At present, the known successful method of multi-rotor helicopters that can realize vertical lift, hovering, and left-right flight has a hexacopter, which adopts six rotors to be respectively arranged on six corners of an equal hexagon, and the center of gravity is at the center of the hexagon. , which changes the lift and anti-torque by manipulating the rotational speed of the rotor to realize the attitude control of the multi-rotor helicopter. Its disadvantage is that when the multi-rotor helicopter is flying forward horizontally, the downwash airflow of the two front rotors will affect the flight of the rear two rotors, and the hexagonal layout occupies the same length vertically and horizontally, and occupies a large area. Contents of the invention [0003]...
