PURPOSE:To raise the combustion efficiency of a gas-turbine engine mounted on an automobile or the like, by correcting the control pattern for an adjustable turbine nozzle according to the atmospheric conditions in controlling the adjustable nozzle for controlling the discharge rate of exhaust gas of a turbine by use of a predetermined control pattern. CONSTITUTION:A gas-turbine engine 10 comprises a gas generator having an intake-air compressor 10A and a turbine 10B fixed to a common shaft, a combustor 10C, an adjustable nozzle 10D for controlling the discharge rate of exhaust gas of the turbine 10B, and a power turbine 10E for driving a right and a left wheels 16 via an automatic transmission 12 or the like. With such an arrangement, the angle of the adjustable nozzle 10D is controlled by a microcomputor 46 according to a predetermined control pattern. Here, under the condition that the turbine temperature is equal to a set temperature, a correction value for the control pattern corresponding to the atmospheric temperature is detected according to the atmospheric temperature T0 detected by an atmospheric-temperature detector 33, and the control pattern is corrected by use of the above correction value. |
