Disclosed is a water-jet propulsion device using a tesla pump. The water-jet propulsion device using a tesla pump is able to optimize a propulsion efficiency of a vessel by using the water-jet propulsion device as a propulsion system of the vessel. According to the present invention, each of water-jets ejected from a plurality of tesla pumps provided in the vessel are gathered to one water-jet in a first propulsion portion, and then are ejected through a second propulsion portion connected to one end of the first propulsion portion. At the moment of water-jet ejection through the second propulsion portion, a diameter of a discharging port formed in the second propulsion portion is controlled for controlling an eject velocity (V_B) of the water-jet such that an acceleration of the water-jet propulsion device can be controlled. Since the second propulsion portion is connected so as to have an angle controllable in vertical and horizontal direction from the rear side of the first propulsion portion, a propulsion direction of the water-jet propulsion device can be controlled.

    테슬라 펌프를 이용한 워터젯 추진 장치가 개시된다. 테슬라 펌프를 적용한 워터젯 추진 장치를 선박의 추진체로 이용함으로써 선박의 추진 효율을 극대화시킬 수 있다. 본 발명에 따르면, 선박에 구비된 복수의 테슬라 펌프로부터 분사된 각각의 워터젯은 제1 추력부에서 하나로 모여진 후, 제1 추력부의 일단과 연결된 제2 추력부를 통해 분사된다. 이때, 제2 추력부에 형성된 분출구의 직경을 제어하여 워터젯이 분사되는 속도 V를 조절함으로써 워터젯 추진 장치의 가속도를 제어할 수 있고, 제2 추력부는 제1 추력부의 후측에서 상하 및 좌우로 각도가 조절될 수 있도록 연결됨으로써 워터젯 추진 장치의 추력 방향을 제어할 수 있다.
