Abstract
An aircraft deicing assembly 101 for attachment to an airfoil 99 includes a deflection shell 101 disposed over a deflection means 102. The deflection shell is comprised of a primary layer 116 comprised of a high strength fabric reinforced with a phenolic resin and a backing layer 115 comprised of a high strength fabric reinforced with an epoxy resin. The thickness of the backing layer is varied as a function of curvature of the airfoil and spanwise length of the airfoil.
Claims12
A deicer for attachment to an airfoil comprising from top to bottom:
- a primary layer comprised of a first composite;
- a backing layer comprised of a second composite, said backing layer having a thickness which varies as a function of the curvature of the airfoil;
- and,
- distortion means for distorting said primary layer and said backing layer in order to impose strain in ice accumulated on said primary layer.
A deicer for attachment to an airfoil comprising from top to bottom:
- a primary layer comprised of a first composite;
- a backing layer comprised of a second composite;
- and,
- distortion means for distorting said primary layer and said backing layer in order to impose strain in ice accumulated on said primary layer.
- wherein said backing layer has a thickness which varies as a function of spanwise position on the airfoil.
A deicer comprising:
- a primary layer comprised of a first composite;
- a backing layer comprised of a second composite, said backing layer having a thickness which varies as a function of the curvature of the deicer;
- and,
- distortion means for distorting said primary layer in order to impose strain in ice accumulated thereon.
A deicer comprising:
- a primary layer comprised of a first composite;
- a backing layer comprised of a second composite;
- and,
- distortion means for distorting said primary layer in order to impose strain in ice accumulated thereon,
- wherein said backing layer has a thickness which varies as a function of position relative to said distortion means.
