Study on bleed air anti-icing system of aircraft

The basic structure and application background of the bleed air anti-icing system of aircraft was introduced, and its development history and present development situation at home and abroad were reviewed. The main research contents were analyzed from four key points, including the calculation of anti-icing surface droplet impingement property, the modeling of external icing/runback water of skin, the study of the internal structure parameters of bleed air anti-ice system, and multiphase coupling simulation of anti-icing system. Finally, the development trend of bleed air anti-icing system was shown via the analysis of the accurate prediction of three-dimensional accreting process of runback ice, optimization method of internal structure parameters of bleed air anti-icing system, the determination of the anti-icing system's safety boundary and margin, the parameters' scaled model icing-wind tunnel experiment of anti-icing system.
