Abstract

The invention provides a novel multi-propeller helicopter, which comprises a fuselage main-body, a main propeller, a main propeller rotating shaft and an empennage. A wing is horizontally and transversely installed below the fuselage main-body. Two sides of the wing are respectively provided with a sub-propeller. The wing is composed of a fixed wing, a movable wing and a rotating shaft, wherein the movable wing is turnably connected with the fixed wing through the rotating shaft. Each of the two sub-propellers is in transmission connection with a corresponding engine. One side of a shell of the engine is fixedly connected to the rotating shaft. The central part of the rotating shaft is turnably connected to an electric motor through a transmission mechanism. By the adoption of the propeller structure and the wing structure, the helicopter has stable balance ability and good safety performance.

Description

technical field [0001] The invention relates to a helicopter, in particular to a novel multi-propeller helicopter, belonging to the technical field of aircraft manufacturing. Background technique [0002] The helicopter in the prior art has a relatively complex wing structure, which increases the production cost on the one hand and affects the overall operating performance of the airframe on the one hand. Contents of the invention [0003] The purpose of the present invention is to provide a novel multi-propeller helicopter, which can make the overall operation of the body more stable and reliable by simplifying the structure of the wings. [0004] Technical solution of the present invention: novel multi-propeller helicopter, comprising fuselage main body, main propeller, main propeller rotating shaft and empennage, a wing is horizontally installed on the lower part of fuselage main body, and the two sides on wing are installed respectively The propeller, the wing is comp...
