Pneumatic de-icer having improved aerodynamic characteristics

摘要

A de-icer for attachment to an airfoil subject to impingement by an airstream. The airstream induces a stagnation line near the leading edge of the airfoil. The de-icer has inflatable passages that are parallel to the airstream overlying the airfoil on one side of the stagnation line, and inflatable passages that are parallel to the leading edge overlying the airfoil on the other side of the stagnation line. The de-icer maintains the aerodynamic characteristics of the airfoil during de-icer inflation. A method of manufacturing the de-icer is also provided.
