PROBLEM TO BE SOLVED: To provide a structure of an induction heating system in an aircraft induction-heating anti-icing system including a ferromagnetic susceptor, a heating coil and an AC(Alternate Current) power source, which enables uniform heating of a susceptor of an anti-icing system by eliminating a cold spot.SOLUTION: An induction heating system comprises: a ferromagnetic susceptor; at least one electrically conductive coil 120 provided proximately to the ferromagnetic susceptor, and powered by a first power source 161a with a first frequency; and at least one compensating coil 160 provided proximately to the ferromagnetic susceptor, having a geometry determined to provide substantially net-zero magnetic flux with respect to the at least one electrically conductive coil, positioned to induce induction heating where the at least one electrically conductive coil lacks induced inductive heating coverage, and powered by a second AC power source 161b with a second frequency.SELECTED DRAWING: Figure 2A |
