Predictions of airfoil aerodynamic performance degradation due to icing

One of the major elements of the NASA Aircraft Icing Research Program is the development and validation of a series of mutually compatible computer codes which predict the details of an aircraft icing encounter. These codes once validated can be used for: 1. Making preliminary design studies to ascertain component sensitivity to icing. 2. Making performance predictions of proposed ice protection systems. 3. Conducting computer based certification/qualification studies to reduce the amount of required icing flight testing. 4. Providing more accurate and realistic icing-effects inputs for use in flight training simulators.
