Beschreibung
Zusammenfassung:A cooled turbine blade (440) is disclosed herein. The cooled turbine blade having a base (442) and an airfoil (441), the base including cooling air inlets (481) and channels (483), and the airfoil including an multi bend heat exchange path (470) beginning at the base and ending at a cooling air outlet (471) at the trailing edge (447) of the airfoil. The airfoil also includes a skin (460) that encompasses a tip wall (461) and an inner spar (462). 本文公开了一种冷却涡轮叶片(440)。所述冷却涡轮叶片具有基部(442)和翼型件(441)，所述基部包括冷却空气入口(481)和通道(483)，所述翼型件包括在所述基部处开始且在所述翼型件的后缘(447)处的冷却空气出口(471)处结束的多弯曲热交换路径(470)。所述翼型件还包括表皮(460)，所述表皮包围尖端壁(461)和内翼梁(462)。
