The present invention relates to a propulsion apparatus for ships using a contra-rotating propeller, which is intended to measure the speed of a counter current with a sensor and control the contra-rotating propeller. The propulsion apparatus for ships includes a ship, a first shaft installed at a rear end and rotated by an engine, a first propeller installed on one side of the first shaft and rotating in accordance with the rotation of the first shaft, a receiving part having one side coupled to a longitudinal end of the first shaft and a hole formed at the center of the other side, a driving part installed inside the receiving part and having a shaft coupled to the hole, a hub fixedly coupled to an end of the shaft of the driving part, and a second propeller installed in the hub and rotated. A current speed sensor for measuring the speed of a counter current is provided in the receiving part. Therefore, it is possible to measure the speed of a counter current generated in front of the contra-rotating propeller with the sensor, and to control the contra-rotating propeller according to the speed of the counter current measured, maximizing the efficiency of propulsion.

    센서를 통해 반류의 속도를 측정하고, 이중반전 프로펠러를 제어하고자 한 이중반전 프로펠러를 이용한 선박용 추진장치에 관한 것으로, 선박, 선박의 후미에 설치되어 엔진에 의해 회전하는 제 1 샤프트, 제 1 샤프트 일측에 설치되고, 제 1 샤프트의 회전에 따라 회전하는 제 1 프로펠러, 일면이 제 1 샤프트 종단에 결합되고, 타면 중앙에 홀이 형성된 수용부, 수용부에 내장되고, 축이 홀에 결합되는 구동부, 구동부의 축 끝단에 고정결합되는 허브 및 허브에 설치되어 회전하는 제 2 프로펠러를 포함하고, 수용부에 반류의 속도를 측정하여 속도정보를 생성하는 유속측정센서를 구비하며, 이중반전 프로펠러 앞에서 발생하는 반류의 속도를 센서로 측정하고, 측정한 반류의 속도에 따라 이중반전 프로펠러를 능동적으로 제어할 수 있으며, 추진 효율을 극대화 할 수 있다
