Abstract
Description
헬기의 프로펠러가 부력을 얻으려면 상당한 시간동안 프로펠러가 원심운동을 하여야 헬기가 부력을 얻게 되는데, 긴급을 요하는 전시용 및 구조용등의 헬기는 보다 빠른 이륙을 요하게 된다.In order for the propellers of the helicopter to gain buoyancy, the propellers must be centrifuged for a considerable period of time before the helicopter can gain buoyancy. Helicopters, such as emergency wartime and rescue vehicles, require faster takeoff.
이를 해소하기 위하여 프로펠러의 원심운동에서 발생하는 구심력을 회전에너지로 전환하게 하여서, 헬기의 긴급이륙에 필요한 부력을 증대 시키게 한다.In order to solve this problem, the centripetal force generated from the propeller centrifugal motion is converted into rotational energy, thereby increasing the buoyancy necessary for emergency takeoff of the helicopter.

헬기의 이륙을 가속하는 방법에 있어서 도 1과 같은 'ㅡ형'프로펠러(UH1H의 프로펠러의 경우)를 예로 들어서 설명을 하자면 다음과 같다.In the method of accelerating takeoff of the helicopter, the following description will be given by taking the '-type' propeller (UH1H propeller) as shown in FIG. 1 as an example.
도3과 같이 프로펠러(2)의 일정 내부에(6) 추(3)를 내설 하여서 이동할 수 있게 하는 강(6)을 형성 하게 하고, 프로펠러(2)는 비자성체로 축(3)은 자성체로 형성하게 한다. 상기 프로펠러(2)와 연결 되어서 엔진의 동력을 전달하게 하는 축(1)의 내부에는 전자석(7) 및 전선(5)을 내설 하여서 센서(4)와 연결되게 하고, 상기 축은 비자성체로 형성하게 한다. 상기의 구성은 엔진으로부터 회전력을 얻게되는 축(1)을 통하여 프로펠러가 회전운동을 하면서 원심력을 갖게 된다. 상기 원심력에 있어서 구심력의 작용은 다음과 같이 이뤄지게 한다. 상기 프로펠러가 원심력을 갖게 되면 센서(4)가 이를 감지하여서 프로펠러의 회전력에 대응하여 적절한 자력을 전자석(7)이 가질 수 있도록 전력을 공급하게 하고, 상기 전자석의 자력으로 상기 프로펠러 내부에 있는 추를 도1에서 도2와 같이 끌어 당기게 하여서 구심력을 얻게 한다.As shown in Fig. 3, the internal portion 6 of the propeller 2 has a weight 3 therein so as to form a steel 6 that can be moved, and the propeller 2 is made of nonmagnetic material and the shaft 3 is made of magnetic material. To form. An electromagnet 7 and an electric wire 5 are installed inside the shaft 1 connected to the propeller 2 to transmit power of the engine so as to be connected to the sensor 4, and the shaft is formed of a nonmagnetic material. do. In the above configuration, the propeller has a centrifugal force while the propeller rotates through the shaft 1 which obtains the rotational force from the engine. The action of centripetal force in the centrifugal force is made as follows. When the propeller has a centrifugal force, the sensor 4 senses this and supplies electric power so that the electromagnet 7 can have an appropriate magnetic force in response to the rotational force of the propeller, and the weight inside the propeller is caused by the magnetic force of the electromagnet. 1 to pull as shown in Figure 2 to obtain a centripetal force.
상기의 구심력을 원심력(프로펠러의 회전력)에 가헤게 되면 회전운동은 가속 되어지게 되고, 따라서 헬기의 이륙시간이 단축 되어지며, 이로인해 헬기의 긴급 구조등의 출동시간이 단축 되어지게 되어서 인명 피해 및 작전 시간을 벌일 수 있다.When the centripetal force is applied to the centrifugal force (rotational force of the propeller), the rotational movement is accelerated, and thus the take-off time of the helicopter is shortened, thereby shortening the dispatch time of the emergency rescue of the helicopter. You can buy time for operations.
