According to the present invention, a whirl tower system for testing a rotor blade of a rotorcraft includes: a whirl tower on which a rotor blade is mounted and which rotates the rotor blade; and a fence device provided in a cylindrical shape of surrounding the whirl tower while having a certain interval therewith, restricting soaring of the rotor blade by separation from the whirl tower, and preventing a noise generated in accordance with rotation of the rotor blade. Accordingly, the present invention prevents the noise generated when testing performance of the rotor blade coupled to the whirl tower to be possible to satisfy environmental standards with respect to noise vibration regulations.

    본 발명에 따른 회전익 항공기의 로터 블레이드 테스트용 훨 타워(whirl) 시스템은 로터 블레이드가 장착되며 로터 블레이드를 회전시키는 훨 타워 및 훨 타워와 일정 간격을 두고 둘러싸는 통 형상으로 마련되며 휠 타워로부터의 이탈에 의한 로터 블레이드의 비상을 제한하고 로터 블레이드의 회전에 따라 발생된 소음을 방음시키는 펜스 장치를 포함하는 것을 특징으로 한다. 이에 의하여, 훨 타워에 결합된 로터 블레이드의 성능 테스트 시 발생되는 소음을 차단하여 소음진동규제에 대한 환경 기준을 만족시킬 수 있다.
