WebNov 1, 2024 · An experimental campaign was conducted to study dynamic ice accretion on rotating aeroengine fan blades and evaluate the icing-induced performance degradation to the fan rotor. The experiments were performed in an icing research tunnel with a scaled spinner-fan model exposed to typical dry rime and wet glaze icing conditions. Webperformed a series of tests using the Boeing 18-inch fan rig (Ganz et al.J). These tests were directed toward identifying and separating the prominent noise sources in a typical high-bypass turbofan setting. The large test matrix included cases with the inlet boundary layer removed, fan only without a stator row, and fan-stator combination.
