Self-balanced torque multiple lift helicopter rotor power structure

Abstract

The self-balancing torque multiple-lift helicopter rotor power structure is a power rotor structure mode for doubling the lift of the helicopter, and belongs to the technical field of helicopters. Most of the current drones use multiple propellers to obtain lift and maneuverability. The limitation of motor power and battery capacity makes the take-off weight and flight time unsatisfactory. In the present invention, two (or more) propellers are horizontally and symmetrically placed on both ends of the rotor (as shown in the accompanying drawing of the abstract of the specification), and the pull (push) force in the horizontal direction is generated to make the rotor rotate, and the lift in the vertical direction is generated by the rotor. When the direction pulling force is converted into lift force, it can be amplified to more than 10 times. This makes it possible to greatly increase the take-off weight of the helicopter or extend the flight time under the same motor power and battery conditions. Since the two propellers are symmetrically placed at both ends of the rotor, the torque generated by the motor rotation cancels each other out, so the whole helicopter does not need a tail rotor to balance. The utility model of the present invention is a helicopter (including unmanned and manned aircraft).

Description

[0001] Technical field: [0002] The invention (self-balancing torque multiple lift helicopter rotor power structure) is a power structure for efficiently improving helicopter lift, and belongs to the technical field of helicopters. [0003] Background technique: [0004] At present, helicopters are divided into manned aircraft and unmanned aerial vehicles. [0005] Helicopter manned aircraft usually uses a single rotor driven by the central axis of the rotor. When driving, a counter torque is generated. In order to balance the counter torque, a tail rotor is generally set. The tail rotor has a great influence on the safety of the helicopter (when the tail rotor loses power due to accidental failure or collision, the helicopter will rotate at high speed under the drive of anti-torque, which will cause great danger). At present, single-rotor manned helicopters have the disadvantages of complex technology, high fuel consumption, and poor safety. [0006] Helicopter UAVs usually...
