The present invention relates to a vortex ring thruster utilizing the Coanda effect and a method for evaluating a propulsion performance thereof. Specifically, the vortex ring thruster utilizing the Coanda effect according to the present invention comprises: a primary piston that contracts and moves in a first axis direction to generate a primary jet; and a Coanda Piston that contracts and moves in the direction of a second axis perpendicular to the first axis to create a Coanda Jet, and has a second outlet disposed adjacent to a first outlet of the primary piston. Thus, the present invention can significantly improve the propulsion performance of a vortex ring thruster since the size of the vortex ring is formed relatively large.

    본 발명은 코안다 효과를 활용한 와류 고리 추진기 및 이의 추진 성능 평가 방법에 관한 것으로, 특히, 본 발명에 따른 코안다 효과를 활용한 와류 고리 추진기는 제1축 방향으로 수축 운동하여 주축 제트(Primary Jet)를 생성하는 주축 피스톤(Primary Piston); 및 상기 제1축과 수직을 이르는 제2축 방향으로 수축 운동하여 코안다 제트(Coanda Jet)를 생성하고, 상기 주축 피스톤의 제1출구와 이웃하도록 제2출구가 배치되는 코안다 피스톤(Coanda Piston);을 포함하는 것을 특징으로 한다.
