Coaxial two-propeller reverse rotor wing mechanism and aircraft thereof

Abstract

Disclosed are a coaxial two-propeller reverse rotor wing mechanism and an aircraft thereof. The coaxial two-propeller reverse rotor wing mechanism comprises an upper propeller, an upper rotor wing shaft, an upper cone gear, a lower propeller, a lower rotor wing shaft and a lower cone gear. The upper propeller is fixed at the upper end of the upper rotor wing shaft. The upper cone gear is fixed at the lower end of the upper rotor wing shaft in a sleeving mode. The lower propeller is fixed at the lower end of the lower rotor wing shaft. The lower cone gear is fixed at the upper end of the lower rotor wing shaft in a sleeving mode. The upper rotor wing shaft shares the same axis with the lower rotor wing shaft. The upper rotor wing shaft and the low rotor wing shaft are arranged in an over-the-air mode. The upper propeller is a variable pitch propeller. The upper propeller controls variable pitch through a variable pitch assembly. According to the coaxial two-propeller reverse rotor wing mechanism, angular momentum is low, machine arm shaking is low, flying of the aircraft is more flexible, and the wind resistance is high.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a coaxial dual propeller reverse rotor mechanism and an aircraft thereof. Background technique [0002] Existing multi-rotor aircraft generally use a single-blade system. Due to the angular force, the arm shakes a lot. The disadvantage is that it needs to use a powerful engine, which not only increases the weight of the aircraft, but also increases the production cost of the aircraft. [0003] And the existing multi-rotor aircraft generally uses the single pitch variable system, and its disadvantages are poor wind resistance, slow response speed, large power consumption and other deficiencies. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention proposes a coaxial double-screw reverse rotor mechanism and its aircraft, which has a double-screw structure, has greater lift, and can carry out reverse rotation of the propeller and the lower pr...

[0002] Existing multi-rotor aircraft generally use a single-blade system. Due to the angular force, the arm shakes a lot. The disadvantage is that it needs to use a powerful engine, which not only increases the weight of the aircraft, but also increases the production cost of the aircraft.

[0003] Moreover, the existing multi-rotor aircraft generally use a single-propeller pitch-variable system, which has the disadvantages of poor wind resistance, slow response speed, and large power consumption.
