Embodiment Construction
[0098] figure 1 Shown is a structural axonometric view of a dense propeller helicopter with three rows and four rows and a total of 12 horizontal planes of rotation in the first embodiment of the present invention.
[0099] On the center of gravity P, the top of the fuselage 1 is provided with a crossbeam 3, the left side of the crossbeam 3 is provided with a left first longitudinal beam 41 by the fuselage 1, and a left second longitudinal beam 42 is arranged on the left side of the left first longitudinal beam 41.
[0100] A motor mount 611 is set at the front end of the first longitudinal beam on the left, and a motor 511 is installed on the motor mount 611. The first row and the first column propeller 11 on the left that is horizontally provided with a rotating surface is installed on the motor 511. A motor mount 621 is arranged at the intersection of the beam 41 and the crossbeam 3, and a motor 521 is installed on the motor mount 621. The second row of the first column pro...

The invention relates to a three-row multi-column dense propeller helicopter. A cross beam is arranged at the top of a helicopter body in the gravity center, longitudinal beams are arranged in the left side and the right side of the cross beam, a first row of propellers with horizontal rotating surfaces are arranged at the front ends of the longitudinal beams, a second row of propellers with horizontal rotating surfaces are arranged at the intersection points of the longitudinal beams and the cross beam, and a third row of propellers with horizontal rotating surfaces are arranged at the rear ends of the longitudinal beams. The projections of the rotating surfaces of the propellers on the horizontal plane are very close but not overlapped, the propellers with the horizontal rotating surfaces in three rows and four columns are formed, the propellers are densely arranged to form a whole, like wings of the same fixed wing, propellers with the rotating surfaces perpendicular to the horizontal plane are arranged to provide forward flight power, a 'fixed wing-like flight mode' is achieved, the efficiency of the propellers with the horizontal rotating surfaces is improved, an undercarriage is arranged under the helicopter body near the gravity center, vertical take-off and landing can be achieved, and the helicopter is suitable for long-distance flight and can be applied to transportation, pesticide spraying, forest fire extinguishing, measurement, exploration and the like.
Description
technical field [0001] The invention relates to a dense arrangement of propellers with three rows and multiple rows of rotating planes that do not depend on the airport, and the rotating planes of the densely packed propellers form a whole, just like a fixed-wing wing, at the fuselage head or fuselage head A three-row multi-column dense propeller helicopter is equipped with pull propellers on both sides or thrust propellers at the tail to provide horizontal forward flight power and realize vertical lifting, hovering, forward, backward, left and right flight. Background technique [0002] At present, the known successful method of propeller helicopters that can realize vertical lifting, hovering, front, rear, left and right flight has conventional multi-propeller helicopters. Conventional multi-propeller helicopters have the advantages of simple structure and high reliability, but the propeller efficiency of conventional multi-propeller helicopters is relatively low , the car...
