Abstract

The measurement of icing conditions needs to be carried out accurately by the ice detector system of an aircraft. Ice detector systems should be installed in locations not affected by backwash, rotor downwash or moving doors or other equipment. Various analyses were carried out in order to find the proper locations sufficiently far from these interfering effects. In this study, the optimum position of the ice detector was assessed using computer simulation, with respect to different flight modes, flow velocities and the amount and distribution of liquid water around the sensor.

결빙상태에서 비행 시 결빙수준은 항공기에 장착된 결빙 감지장비에 의해 정확히 측정되어야 한다. 결빙감지기는 항공기 형상으로부터 야기되는 후류, 로터 하강풍 및 출입문이나 다른 장비에 의한 간섭 등으로 부터 영향을 받지 않는 곳에 설치해야한다. 이러한 간섭을 받지 않는 최적화된 위치를 선정하기 위한 분석과 해석을 실시하였다. 본 연구에서는 3차원 컴퓨터 분석을 통해 비행형태별 결빙감지기 주변의 유체의 속도, 수분의 양과 분포 및 크기를 분석하여 최적의 위치를 제안하였다.
