초록

A nacelle inlet lip (22) for an aircraft engine (16) comprises a structural body (30) and an ice protection system (60). The ice protection system (60) comprises a plurality of ice-protectors (62, 64, 66) independently controllable to allow inner zones (52, 54, 56) to be operated in different modes, different power levels, different time intervals and/or different energy amounts. In this manner, an inner aft zone (52), an inner mid zone (54), and an inner aft zone (56) can be anti-iced and/or de-iced to best preserve desired airflow patterns, to minimize...
