The present invention relates to a ship having an auxiliary thrust apparatus installed in the rear side of a propeller. The auxiliary thrust apparatus comprises: a support hub performing free rotation in accordance with the rotation of the propeller; and a plurality of blades radially extended from the support hub and having a curved end. Therefore, as the end is not exposed to the outside of free surface, the present invention can prevent a reduction in propulsion efficiency and can prevent damage at the same time. In addition, vibration and noise due to fluctuation pressure can be reduced by decreasing cavitation.

    본 발명은 프로펠러의 후방에 설치되는 보조 추력장치를 구비한 선박에 관한 것으로, 보조 추력장치는, 프로펠러의 회전에 따라 자유회전하는 지지허브; 및 이 지지허브로부터 방사상으로 연장되고, 끝단이 휘어진 복수의 날개를 포함하는 것을 특징으로 하여서, 끝단이 자유수면 밖으로 노출되지 않게 되어 추진 효율의 감소를 방지함과 동시에 손상을 방지할 수 있고, 공동현상을 저감시켜 변동압력으로 인한 진동 및 소음을 감소시킬 수 있는 효과가 있다.
