Airframe, wing and rotor icing is a critical problem in aerodynamics. Ice changes the geometric shape of surfaces it accretes on, which changes its aerodynamic characteristics in unpredictable and possibly catastrophic ways. The Federal Aviation Administration estimates airframe ice can decrease lift by more than 30 percent and increase drag by more than 80 percent. Developing an increased understanding of ice accretion on aircraft is needed to make flying safer.
