Abstract:Aircraft icing continues to be a threat for modern day aircraft. Icing occurs when supercooled large droplets (SLD’s) impinge on the body of the aircraft. These droplets can bounce off, freeze on impact or freeze partly with the remaining liquid running further down the body. This results in different ice shapes. Several different computer programs have been developed to predict these ice shapes. An example of such a program is 2DFOIL-ICE. 2DFOIL-ICE calculates droplet trajectories using the Lagrangian method. It also calculates the stationary flow around the two-dimensional airfoil to determine different aerodynamic coefficients. To compare the modeled results of the two-dimensional wing to a three-dimensional wing, a modeled ice shape has been fabricated on an ATR-72 wing. To determine the effects of icing on this wing, the wing with icing will be tested in a wind tunnel and compared to a clean ATR-72 wing. These results will then be compared to the results from 2DFOIL to determine the accuracy of the numerical method.
