Abstract

Abstract: An anti-icer with micro-ejector is used in Y7 wing thermal anti-icing system to save the used air.Thermal calculation for the type of this icer is very important for design of the anti-icing system.The calculation of icer is described.A mathematical model of fluid dynamics and thermal calculation for micro ejector and double skin anti-icing passage is es-tablished.The computer program for this type is described too. Practical calculation is carried out with developed program for Y7 wings icer.The method for improving precision and sav-ing computer time is discussed.

Key words: thermal analysis, aircraft icing, ejectors
