Abstract
A pneumatic deicing system includes a deicer assembly comprised of an outer layer having a low modulus of elasticity, an inner ply, and a plurality of inflatable members provided therebetween for imposing strain in ice accumulated thereon. The deicer assembly is disposed directly on top of and bonded to the leading edge of an airfoil. The deicer has a plurality of large radius spanwise running inflatable members arranged substantially parallel to the leading edge and a plurality of small radius spanwise running inflatable members arranged substantially parallel to the leading edge and disposed chordwise aft of the large radius spanwise running inflatable members. The small radius inflatable members are covered with a low ice adhesion surface.
