Document Type and Number:
Japanese Patent JP2016094186
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide systems for multiple zone heaters for rotor craft and methods for operation.SOLUTION: An example system for a rotor craft 100 comprises multiple blades 110, 112, 120, 122 coupled to a rotor 108, 118, and areas of the multiple blades divided into sections. A given blade includes an inboard section extending from the rotor 108, 118 outward and an outboard section extending from the inboard section to a tip of the given blade. The system also includes a plurality of first spanwise heater systems 114, 124 included on respective outboard sections of the multiple blades, a plurality of second spanwise heater systems 116, 126 included on respective inboard sections of the multiple blades, and a control unit 102 coupled to the plurality of first spanwise heater systems and the plurality of second spanwise heater systems. Respective heater systems of the sections of multiple blades are energized in a sequence based on outside air temperature.SELECTED DRAWING: Figure 1
