Effect of Pneumatic De-icers and Ice Formations on Aerodynamic Characteristics of an Airfoil by Dean T. Bowden PDF Summary

Book Description: Measurements of lift, drag, and pitching moment of an NACA 0011 airfoil were made in icing using two types of pneumatic de-icers, one having spanwise inflatable tubes and the other having chordwise tubes. Ice remaining after inflation of the spanwise-tube de-icer increased airfoil section drag 7 to 37 percent for 0 to 4.6 degrees angle of attack over the ranges of airspeed, total air temperature, liquid-water content, and cycle times covered. This drag increase became constant after a few de-icing cycles. Drag increases due to ice remaining on the chordwise-tube de-icer were similar to those for the spanwise-tube de-icer. Minimum airfoil drag in icing (averaged over a de-icing cycle) was usually obtained with a short (about i min) de-icing cycle.
