Vibrating pneumatic deicing system

摘要

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. The deicer assembly is disposed directly on top of and bonded to an airfoil. The inflatable members are inflated with an inflation apparatus that inflates in an inflation pattern comprised of a sequence of high frequency pressure pulses superimposed on a low frequency inflation pressure wave.
