The present invention provides a longitudinal intersecting double-rotor unmanned helicopter, comprising: a first bevel gear, two first steering gears, two shafts, two propeller parts, two operating mechanisms and two transmissions with the same transmission structure mechanism; the transmission mechanism includes a second bevel gear, a third bevel gear and a fourth bevel gear, wherein the second bevel gear meshes with the first bevel gear, the second bevel gear is drivingly connected with the third bevel gear, and the third bevel gear is connected with the third bevel gear The fourth bevel gear meshes; the two transmission mechanisms are respectively arranged on both sides of the first bevel gear; the fourth bevel gear of the two transmission mechanisms is connected to the two shafts in one-to-one correspondence, and the two shafts have opposite rotation directions; A propeller part is installed on the top ends of the two shafts respectively; the first steering gear is driven and connected with the propeller part through an operating mechanism respectively.
Description
technical field [0001] The invention relates to the field of helicopters, in particular to a longitudinally intersecting double-rotor unmanned helicopter. Background technique [0002] In the prior art straight engine, when 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 propeller is provided. The small tail propeller is powered by the engine, so that the small tail propeller The rotation of the propeller produces a pulling force opposite to the rotation direction of the main propeller, which keeps the helicopter fuselage from rotating, while the small tail propeller consumes a certain amount of power, which is the weak part of the helicopter. Contents of the invention [0003] The invention provides a longitudinally intersecting double-rotor unmanned helicopter to solve the problem of power consumption of the small tail rotor in the prior art. [0004...
