ジェットエンジン圧縮機翼の着氷現象に関する研究

抄録

When minute supercooled liquid water droplets or ice impact on a cold object surface in a low-temperature environment, they freeze at the impact surface. This is known as icing phenomena. In aircraft, attention has mainly focused on icing on the aircraft fuselage, but icing also occurs in compressor of jet engines. When icing occurs, not only is the performance of the jet engine decreased, but the detached ice can damage the compressor cascades. Therefore, the icing of compressor cascades is an important issue. In this study, prior to examining the icing on the compressor cascades, we examined the icing on a single blade of compressor. The ice shape and mass to the blades were investigated with flow velocity and attack angle as parameters.
