Abstract:

An investigation was conducted of the requirements for setting icing test conditions for aircraft engine certification tests. Experimental data were gathered and analyzed to determine how much each of the ice scaling parameters could be allowed to deviate from specified conditions without affecting the similarity of the ice accretions. Also studied were how changes in the ice scaling parameters and changes in the icing test conditions themselves affected the resulting ice shapes. The results indicate that (1) icing similitude criteria must be established in advance of the test; (2) changes in the scaling parameters do not necessarily indicate a change in the ice shape; (3)experimental data are useful in determining allowable changes in the icing test conditions; (4) determination of allowable tolerances for icing test parameters will depend on which icing regime one is operating in; and (5) scaling laws used in this report cannot solely be used to determine tolerances in setting icing test conditions.
