The present invention relates to a rotary type spoiler of a railway vehicle for reducing aerodynamic drag, which may comprise: a support frame arranged to protrude along a cross sectional circumference of a driving direction of a railway vehicle; and a rotary connected to the inside of the support frame with a shaft to be rotated. According to the present invention, in response to a change in a driving direction and a driving speed of a railway vehicle, aerodynamic drag generated in a leading vehicle can be integrally and effectively reduced.

    본 발명은 공기저항 저감을 위한 철도차량 회전식 스포일러에 관한 것으로, 철도차량의 주행방향 단면 둘레를 따라 돌출되어 배치되는 지지프레임 및 회전 가능하도록 상기 지지프레임 내부에 샤프트로 연결되는 회전체를 포함하여 구성될 수 있으며, 본 발명에 따르면, 철도차량의 주행방향 및 주행속도의 변화에 대응하여, 선두차량에서 발생하는 공기저항을 통합적이고 효율적으로 감소시킬 수 있는 효과가 있다.
