dc.description.abstract Engine inlet guide vanes (IGVs), located between the air intake components and intermediate compressors, are essential components of aero-engines. IVGs are susceptible to direct impingement of super-cooled water droplets causing ice accretion while aero-engines operate in cold conditions. Ice accretion on IVGs during operation not only blocks the passage of airflow to the compressor but can cause significant foreign object damage and power loss issues (resulting in stall or flameout). In the present study we explored a novel hybrid IGV anti-de-icing strategy that combined the conventional air based anti-icing system and hydro-/ice-phobic coatings with ultra-low ice adhesion strength to reject ice accretion and water runback over IGV surfaces. An experimental investigation was conducted to characterize the effectiveness of the hybrid IGV system with the goal of reducing the requirements of the bleed air for the IGV icing protection, thus reducing the performance penalties to the aero-engines. The study was performed in the icing research tunnel using a hollowed IGV model embedded with a U-shaped hot air flowing conduit coated with various state of the art icephobic coatings, and data on heater temperature, mass flow rate of the hot air system, and effectiveness of the IGV icing protection was taken.
