Swept Airfoil Cases in IceVal

"Use of these relationships allows the direct determination of ice shapes adjusted for any given icing and flight condition as well as for size and sweep of the airfoil" 1 Experimental ice shapes compared to a LEWICE analysis. Summary There are 41 swept airfoil cases in the IceVal database 2. The quote at the top from Wilder briefly describes the the empirically based analytical method he described in 1. However, it is not directly applicable to airfoils other than the ones he considered, which had dozens of icing tunnel ice shapes tests each. For more details on Wilder's method, see Wilder. LEWICE 3, and other codes, offer potentially more widely applicable methods of ice shape prediction in swept airfoils. LEWICE analysis for these cases tends to produce ice shapes that are consistently too small compared to experiment. Empirically derived adjustments to the inputs to LEWICE are discussed that improve the …
