Design and calculation for the anti-icing system of an aircraft engine let

  • A hot-air anti-icing system for an engine inlet was designed. The engine had a flow distribution plate. Based on the calculation of water droplets trajectories, thermal calculation was conducted for the anti-icing system, including the temperature profile of anti-icing surface, pipes pressure loss and flux distribution. The calculation was used to examine if the designed system would work well under the design condition. The influences of air temperature, flux and restrictor diameter on temperature distribution of anti-icing surface were analyzed. The results indicte that the surface temperature increases with the increasing of hot-air temperature and flux, and that the surface temperature of the flow distribution increases with the increasing of restrictor diameter, while the effect of it on leading edge surface temperature can be neglected.
