PROBLEM TO BE SOLVED: To provide a fan control device capable of preventing a normal drive source from being brought into an overload state when part of a plurality of drive sources is broken. SOLUTION: When an FADEC 10 detects an abnormality of either of an engine + compressor 11, 12, an FCC 3 controls an air quantity for fan drive so that it becomes lower than that before the abnormality is detected until the normal engine + compressor 11, 12 can supply air of a flow rate necessary for a fan 1 to generate a thrust force before the abnormality detection. Thus, this can prevent the overload state caused by a surge etc. generated in the normal engine + compressor 11, 12. COPYRIGHT: (C)2009,JPO&INPIT
