Shield member and jet engine using the same

A shield member, disposed over a gap between platform portions of adjacent turbine rotor blades, made from a ceramic matrix composite, and configured to shield the gap between the platform portions, wherein

• the platform portions each include
• a platform portion body formed extending in a direction intersecting a longitudinal direction of a corresponding one of the turbine rotor blades, and
• a front skirt provided on a leading edge side of the platform portion body, and the shield member comprises
• a shield member body formed elongated and including a first shield surface located between shank portions connected to the platform portions of the adjacent turbine rotor blades, the first shield surface configured to shield a gap between the platform portion bodies of the adjacent turbine rotor blades by coming into contact with inner surfaces of the platform portion bodies along the inner surfaces of the platform portion bodies, and
• a leading edge-side shield portion formed elongated and including a second shield surface located between the shank portions of the adjacent turbine rotor blades, a first end in a longitudinal direction of the leading edge-side shield portion integrally provided to a first end in a longitudinal direction of the shield member body while bent from the shield member body, the second shield surface configured to shield a gap between the front skirts of the adjacent turbine rotor blades by coming into contact with inner surfaces of the front skirts along the inner surfaces of the front skirts.
