Abstract

The invention provides a longitudinally crossed dual-rotor helicopter. The longitudinally crossed dual-rotor helicopter comprises a first bevel gear, two first steering engines, two shafts, two propeller parts, two operating mechanisms, and two transmission mechanisms with the same transmission structure; each transmission mechanism comprises a second bevel gear, a third bevel gear and a fourth bevel gear, wherein the second bevel gear is engaged with the first bevel gear and in drive connection with the third bevel gear, and the third bevel gear is engaged with the fourth bevel gear; the two transmission mechanisms are arranged at the two sides of the first bevel gear, respectively; the fourth bevel gears of the two transmission mechanisms are corresponding connected with the two shafts one to one, and the two shafts are opposite in rotation direction; the two propeller parts are mounted at the top ends of the two shafts, respectively; the first steering engines are in drive connection with the propeller parts by use of the operating mechanisms, respectively.

Description

Technical field [0001] The invention relates to the field of helicopters, in particular to a longitudinal cross-type dual-rotor unmanned helicopter. Background technique [0002] In the direct generator in the prior art, as the main propeller rotates to generate lift, it also produces a reaction force opposite to the propeller rotation. In order to overcome this reaction force, a small tail slurry is required. The small tail slurry is powered by the engine to make the small tail The rotation of the propeller produces a pulling force that is opposite to the direction of rotation of the main propeller, which keeps the helicopter body from rotating, while the small tail propeller consumes a certain amount of power, which is a weak part of the helicopter. Summary of the invention [0003] The present invention provides a longitudinal cross-type dual-rotor unmanned helicopter to solve the problem of power consumption for small tail rotors in the prior art. [0004] In order to solve the...
