摘要： A method of detecting that ice (130) has been shed from an external surface (111) of a component (110) is provided, the method comprising applying power to a heating means (120) to provide heat to said external surface (111). The method further comprises sensing the temperature of the component (110) and calculating the rate of change of temperature increase of the external surface (111) over time. Further, the method comprises detecting a change in said rate of change of temperature increase over time, wherein said detected change in rate of change of temperature increase indicates that said ice has been shed from said external surface (111) of said component (100).

摘要： A propeller blade (10) comprises an airfoil (20) having an airfoil core (22) comprising a radially inner base (24), a radially outer tip (26) and a leading edge (28), a root (30) extending from the base (24) of the airfoil core (22) for attaching the airfoil (20) to a hub and a thermally conductive sheath (40) attached to the leading edge (28) of the airfoil core (22) and extending from the base (24) to the tip (26) of the airfoil core (22). An electric heater (60) is arranged between the airfoil core (22) and the thermally conductive sheath (40) in at least a radially inner portion (50) of the leading edge (28). An erosion resistant coating (90) is provided only on a radially outer portion (80) of the thermally conductive sheath adjacent the tip (26).
