Abstract:
본 발명에 의한 비행체는 복수의 로터블레이드 또는 제트엔진을 구비하되, 그 가운데 어느 하나가 손상되어도 추락의 위험성을 줄일 수 있도록 개발된 것으로, 비행동체와; 동일 원주상에 복수의 관통공이 형성된 판상의 보호부재와; 상기 각 관통공 내에 배치되는 구동수단과; 상기 각 구동수단을 경사지게 하는 틸팅수단; 또는 보호부재를 상기 축부재에 대해 회동시키는 회동수단을 갖는다. 이때, 보호부재의 직경, 서로 대향되는 로터블레이드의 회전축간 간격, 축부재의 길이 및 비행동체의 길이는 소정의 비율을 갖는다.
Abstract:
A ganged servo flight control system for an unmanned aerial vehicle is provided. The flight control system may include a swashplate having first, second, and third connection portions; a first control assembly connected to the first connection portion of the swashplate; a second control assembly connected to the second connection portion of the swashplate; and a third control assembly connected to the third connection portion of the swashplate. The first control assembly may include two or more servo-actuators connected to operate in cooperation with each other.
Abstract:
The control system for rotary-wing aircraft (1) has a rod connection between the main rotor blades (14, 15) and a swash plate (63) which is operationally connected to a pilot's control handle (28) on the one hand and on the other is connected to the main rotor blades (14, 15) via levers (62, 66) with their axes of rotation lying substantially in one plane. When the pilot's control handle (28) is pushed forward, the swash plate (63) is inclined forwards and downwards with no lost motion so that the forward main rotor blade (14 or 15) assumes its smallest angle of attack. This control system has no lost motion. The pilot therefore experiences it as a rigid system of rods when performing control movements. The system thus responds rapidly and accurately.
