The aim of the third funding phase is to test and investigate dynamically forced impingement cooling concentrating on its application in a realistic two-dimensional blade geometry. The main focus is on the development of an actuation system based on fluidic actuators without mechanically switching parts. These actuators will be employed to design a fluidically self-switching impingement jet array that can be scalably adapted to different test carrier sizes. This will contribute to the control of thermal load peaks within the turbine blading due to pressure-increasing combustion.

第三个资助阶段的目的是测试和研究动态强制撞击冷却，重点研究其在现实二维叶片几何中的应用。主要的重点是基于流体致动器的驱动系统的发展，没有机械开关部件。这些驱动器将用于设计一种流体自开关冲击射流阵列，该阵列可扩展适应不同的测试载体尺寸。这将有助于控制涡轮叶片内由于压力增加燃烧而产生的热负荷峰值。
