Abstract: PURPOSE: A laser-fight training facility of a grenade launcher is provided to exercise under simulated combat conditions of a grenade launcher similar to actual fighting of an army by producing laser arms generating injuries similar to an actual arm. CONSTITUTION: A laser-fight training equipment of a grenade launcher consists of a shooting assistant(1000), a mounting unit(2000), a laser launcher(3000) and a launcher fixing unit. The shooting assistant is installed on a side of a gun body(1). The shooting assistant automatically calculates an altitude to a target from a shooter and then transmits the altitude data to the laser launcher through wire or wireless communication. The mounting unit is used to mount the shooting assistant on a side of the gun body of a grenade launcher. The laser launcher is installed under the gun body of the grenade launcher through the launcher fixing unit. The laser launcher is used instead of an actual launcher. The laser launcher compares the altitude data from a shooter to a target received from the shooting assistant with altitude data obtained by the neck of a shooter. If the difference between the two kinds of altitude data is within a set value, a trigger is turned on and laser beam is launched to a target. The launcher fixing unit mounts the laser launcher under the gun body removably. The laser-fight training equipment is designed to generate almost actual injuries for exercise under simulated combat conditions. Therefore, the military strength increases.

Abstract: 본 발명은 조력 발전 장치에 관한 것이다. 종래 조력 발전 장치 중 조수의 수평유동력을 이용한 발전 장치는 조수의 유동 방향에 축선(軸線)을 일치시킨 축류 터빈(Axial Flow Turbine)을 사용하는 것으로 조수의 속도와 유량만을 이용하게 되기 때문에 원하는 발전 효율을 기대할 수 없었다. 또한 축류 터빈의 축을 조수의 유동 방향과 평행한 방향, 즉 수평 방향으로 설치하기 때문에 터빈의 하중이 축을 통하여 축을 지지하는 축받이(Bearing)의 하반부에 집중적으로 작용하게 되기 때문에 축받이 효율이 떨어지게 되어 에너지의 기계적 손실(Mechanical Loss)이 크게 발생되어 동력 발생 효율이 저하되고 결국 발전 효율이 저하되는 문제점이 있었다. 본 발명은 조수유입구와 조수유출구 사이에 높이 차를 두고 설치하고, 조수유입구보다 낮고 조수유출구보다 높은 위치에 임펠러가 수평 회전하는 터빈을 설치하는 것에 의하여 수평으로 유입된 조류를 급차단하여 수직으로 급락시켜 가중된 수압으로 터빈을 회전시켜 발전효율을 높일 수 있도록 한다. 또한 간만에 관계없이 복식 발전이 가능하도록 한 것이다.
