The aim of this subproject is to reduce the unavoidable residual pulsations to a level that is tolerable for the compressor and turbine by using plena between the combustion tubes and the turbo components. This project investigates the feedback between the plenums and the adjacent turbo components. In addition, new concepts for cooling and shock reduction are developed in the plenum. As in the second funding period, experimental and numerical investigations are closely interlinked. The methods developed will also be applied to design and operate the demonstrator.

该子项目的目的是通过在燃烧管和涡轮部件之间使用集气层，将不可避免的残余脉动降低到压缩机和涡轮机可以承受的水平。该项目研究静压室和相邻涡轮部件之间的反馈。此外，静压室还开发了冷却和减震的新概念。与第二个资助期一样，实验和数值研究紧密相连。开发的方法也将应用于演示器的设计和操作。
