Propeller heater lead

摘要

Heater leads for a leading edge resistive heating element are configured to accommodate the relative movement of the propeller blades to adjust propeller blade pitch. The heater leads each include a static portion and a dynamic portion. The static portion remains fixed relative to the rotating propeller during operation and the dynamic portion moves with movements of the individual blades to adjust pitch. The length of the dynamic portion accommodates the limits of movement and includes features that provide the desired performance and operational life.

主权项

1. An electrical lead for a propeller resistive heating system comprising:
a first terminal lug and a second terminal lug, wherein the first terminal lug and the second terminal lug are attached at distal ends of an electrically conductive cable, and a protective cover disposed on the conductive cable having an edge spaced a first length from the second terminal lug to define a dynamic portion of the electrical lead, wherein a ratio of an overall length between the first terminal lug and the second terminal lug and the first length is between 1.49 and 1.51:1.
