The project aims to transfer the results of the previous funding periods for active flow control in compressors to realistic engine conditions. For this purpose, experimental investigations are carried out on two high-speed test rigs in order to develop an actuator system, which can be used in the relevant Mach number regime of up to Ma∞= 0.6 upstream of the compressor cascade. By means of numerical flow simulations, fluidic actuators are designed for application in highly compressible flows with the aim of adapting the actuator characteristics to turbomachine-like flow conditions. Subsequently, the effect of the whole actuator system for flow control with an adjustable throttle valve will be used in a full-scale annular test rig under representative periodically unsteady flow conditions.

该项目旨在将以往供资期间压缩机主动流量控制的结果转化为实际发动机条件。为此目的，在两个高速试验台上进行了试验研究，以研制一种作动器系统，该作动器系统可用于压气机叶栅上游Ma∞= 0.6以下的相关马赫数范围。通过数值流动模拟，流体致动器的设计应用在高度可压缩流的目的是适应致动器的特性，以类似于涡轮机的流动条件。随后，在具有代表性的周期性非稳定流条件下，将在全尺寸环空试验台中使用具有可调节节流阀的用于流量控制的整个致动器系统的效果。
