DEICER ZONES WITH SHEDDING-ENHANCED BORDERS
First Claim
Patent Images
1. An ice protection system comprising a first set of contiguous deicing zones;
- wherein;
each deicing zone comprises an envelope defining an ice-protection area;
each envelope includes an electrothermal heater layer which converts electric power to heat to deice the corresponding ice-protection area;
at least two of the envelopes are adjacent and share a common interzone border;
each of the adjacent envelopes includes an edge region flanking the interzone border; and
the edge regions of the adjacent envelopes are configured to enhance deicing at the interzone border by having nonlinear contours with edge features which project-and-recess in a direction substantially parallel to the airstream direction.

Abstract
An ice protection system comprises deicing zones each including an envelope defining an ice-protection area. Adjacent envelopes have spanwise edge regions flanking shared interzone borders. The edge regions are provided with nonlinear contours having features which project-and-recess in a direction generally parallel to the airstream direction.
