PROBLEM TO BE SOLVED: To provide technology easing thermal stress generated on a turbine blade. SOLUTION: This engine is provided with a transfer member 43 provided in a housing of a turbine and transferring radiation energy radiated from a combustor to the turbine blade, interruption members 6, 7 supported reciprocatably in an axial direction of a rotary shaft of a turbine on an outer side of a housing 41 and interrupting radiation energy not to reach the turbine blade 42, a position control means 8 controlling position of interruption members 6, 7 in relation to the turbine blade 42 according to an operation condition. The position control means 8 controls position of the interruption member to interrupt radiation energy reaching a front end part and a rear end part of the turbine blade 42 at a time of increase of engine load, and controls position of the interruption members 6, 7 to interrupt radiation energy reaching a center part at a time of decrease of engine load.
