A look at the current state of icing condition scaling or icing similitude for application to aircraft inlet/engine systems is presented. The influences of aircraft flight Mach number and the engine power setting are considered in determining the icing test conditions that must be considered for application of icing similitude. Some of the recent studies into this area of icing similitude are discussed. Some typical examples of the influences that flight Mach number, engine power setting, and free-stream icing conditions have on the icing conditions that exist throughout an inlet/engine system are presented. Data are presented that indicate the critical influence of temperature changes upon ice accretions and of the insignificant influence of pressure changes upon ice accretions. Summary conclusions and recommendations for further study are given.
