Abstract:
1. A system for detecting sensor malfunction of a gas-turbine engine, comprising: a sensor installed at the engine and outputting a value indicative of operating condition of the engine; a determiner inputting the value outputted from the sensor and determining once every first predetermined time period whether the outputted value is not within a permissible range; a discriminator inputting a result of determination of the determiner and discriminating that the sensor is faulty, when the result is at least one of a case in which number of times the outputted value is determined not to be within the permissible range, is not smaller than a first predetermined value, and a case in which the number of times, the outputted value is consecutively determined not to be within the permissible range, is not smaller than a second predetermined value; and a fuel control unit calculating a flow rate of fuel to be supplied to the engine once every second predetermined time period that is m (m≧2) times of the first predetermined time period and controlling fuel supply so as to supply fuel at the calculated flow rate; and the second predetermined value is set a value that is equal to or smaller than a value corresponding to the second predetermined time period.
