Any aircraft have the possibility to encounter icing atmospheric condition in flight or on the ground. The occurrence of ice accretion leads to the performance degradation in jet engines and cause serious mechanical damage to the fan and the compressor components of jet engines. Therefore, jet engines of aircraft need to prove the ability to work on icing conditions to match the certification criteria. If we can simulate ice accretion and improve the performance in design phase, it should become possible to reduce the cost and design period of jet engines. In the present study, we simulated ice accretion of rotor-stator interaction between the fan and the FEGV of jet engines to investigate the ice shape and how the ice affects the aerodynamic performance. It was confirmed that the amount of ice is much larger on the rotor than on the stator, and the stator has only thin ice layer on the leading edge.
