摘要

A modular fan inlet ice protection system 10 includes a center ring 12, an outer ring 14 and a plurality of struts 16. The struts 16 are each coupled at a first end 18 to the center ring 12, and at a second end 20 to the outer ring 14. A plurality of shell members 22 are each configured to be removably coupled to a corresponding strut 16. Moreover, the shell members 22 each include an electrothermal heater element 24. Preferably the system 10 further includes a plurality of inlet guide vanes 26 each including an electrothermal heater element 28.
