Claims (2)
- コンプレッサ(23)で圧縮した空気に燃料を混合して燃焼室(29)で燃焼させ、燃焼により発生した高温の燃焼ガスが供給されるタービン(32)が、上流側のノズルガイドベーン(35)および下流側のタービンブレード(56)を含むガスタービンエンジンであって、
前記ノズルガイドベーン(35)の径方向内端を支持する内側プラットフォーム(47)と、前記内側プラットフォーム(47)から径方向内側に延びる第1隔壁部材(48)と、前記第1隔壁部材(48)に径方向内端部が固定されて前記内側プラットフォーム(47)に径方向外端部が対峙する第2隔壁部材(50)とにより、前記内側プラットフォーム(47)の軸方向略全長にオーバラップする環状の中温空間(51)を形成し、前記第2隔壁部材(50)の径方向内側に前記コンプレッサ(23)から空気が供給される低温空間(52)を形成したことを特徴とするガスタービンエンジン。 - 前記内側プラットフォーム(47)の下流側端部と前記第2隔壁部材(50)の下流側端部との間に前記タービンブレード(56)のプラットフォーム(55)の上流側端部を挿入することで、前記ノズルガイドベーン(35)および前記タービンブレード(56)間の隙間からの燃焼ガスの漏れを防止するシール部(57)を構成したことを特徴とする、請求項1に記載のガスタービンエンジン。
