Problems solved by technology

However, the helicopter has the following disadvantages: due to the use of the tail rotor, the output is reduced, and the balance of the airframe cannot be maintained when the tail rotor fails.
Therefore, conventional controllers cannot be used to control the intersecting contrarotor aircraft

Abstract

The present invention relates to an intermeshing rotary-wing aircraft, comprising: a first rotary blade portion including a first blade and a second blade; a second rotary blade portion including a third blade and a fourth blade; a first shaft and a second shaft that transmit power to the first rotary portion and the second rotary portion and are symmetrically positioned at a predetermined angle;a first swash plate portion for controlling the first blade and the second blade; and a second swash plate portion for controlling the third blade and the fourth blade, wherein the first swash plate is coupled to three linkages, in which the coupled positions are located at the vertices of an equilateral triangle, the second swash plate has the same shape as the first swash plate, and the two equilateral triangles of the first swash plate and the second swash plate are star-shaped when horizontally moved and overlapped.

Description

technical field [0001] The technical field of the invention relates to rotorcraft with intersecting contra-rotating rotors using swashplates. Background technique [0002] Recently, drones and remote-controlled aerial vehicles (drone) have attracted attention in various application fields. However, the remote-controlled aircraft cannot carry much weight structurally, so there is a disadvantage that a large number of power supply devices such as batteries cannot be installed. Therefore, the remote control aircraft is limited by the moving distance, and has the disadvantage of being limited by the moving speed structurally. [0003] Due to the above-mentioned disadvantages, in various fields such as industrial use, a helicopter (helicopter) is generally used instead of a rotorcraft called a remote control aircraft. However, the helicopter has disadvantages in that the output is reduced due to the use of the tail rotor, and the balance of the airframe cannot be maintained whe...
