초록

회전익기의 공기흡입구 주위 표면에 발생한 결빙은 엔진의 성능을 저해하는 요인으로 비행 안전성에 심각한 영향을 끼칠 수 있다. 항공기 표면에 발생하는 결빙현상을 분석하는데 많은 비용이 소요되는 결빙 풍동 시험 및 비행시험에 비해 전산유체역학을 기반으로 한 결빙 시뮬레이션은 매우 효과적인 도구가 될 수 있다. 본 연구에서는 결빙조건에서 회전익기 공기흡입구 부근에 설치된 방빙장치의 작동 유무에 따른 결빙의 양과 발생 영역을 CFD 예측기법 및 결빙 풍동시험을 통해 분석하였다. 방빙장치를 작동시킨 경우 공기 흡입구 표면에서의 결빙의 질량과 최대 두께가 약 80% 이상 감소하는 것을 확인하였다.

Ice accretions on the surface around a rotorcraft air intake can deteriorate the safety of rotorcraft due to the engine performance degradation. The computational simulation based on modern CFD methods can be considered extremely valuable in analyzing icing effects before exact but very expensive icing wind tunnel or in-flight tests are conducted. In this study the range and amount of ice on the surface of anti-icing equipment are investigated for heat-on and heat-off modes. It is demonstrated through the computational prediction and the icing wind tunnel test that the maximum mass and height of ice of heat-on mode are reduced about 80% in comparison with those of heat-off mode.
