CONTROL DEVICE FOR GAS TURBINE ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a control device for a gas turbine engine, in which if the engine is in a transient state including acceleration or in a stationary state is determined with favorable precision. SOLUTION: This device comprises a first and a second control systems to control fuel supply to the engine based on all or part of inputted values outputted from a group of sensors. At least four values outputted from at least two high pressure turbine rotation sensors (N2 sensors) are inputted to them. If at least three values of them are in such a range as to be valid as the same value or not is determined (in a validity determination block 308). If at least three values of them are in such a range as to be valid as the same value with at least one of the others is determined through four-value comparison to determine if sensor output is valid for fuel supply control or not (in the validity determination block 308).
