Experimental analysis of the interaction phenomena between hot nozzle flow and transonic external flow (B01)

在即将到来的资助期内，子项目B1的主要目标是研究跨声速区热羽与外部流动的相互作用。不同混合比的H2O2燃料将允许在发射器模型的基础上对空气动力学和空气热现象进行系统研究。实验将采用金属喷嘴和CMC喷嘴，研究壁面温度和热辐射对发射器底座区域气动热相互作用的影响。此外，子项目B3、B4和B6开发的最有前途的被动和主动流量控制技术将用于VMK的飞行相关测试配置。在实验数值模拟方面将与子项目B5有很强的合作。

The main objective of the sub-project B1 in the upcoming funding period is the study of the hot plume inter-action with the external flow in the transonic regime. H2O2 fuel with different mixture ratios will allow per-forming a systematic study on the aerodynamic and aerothermal phenomena in the base of a launcher model. Experiments will be carried out using metallic and CMC nozzles to study the influence of the wall temperature and thermal radiation on the aerothermal interaction in the launcher base region. In addition the most promising passive and active flow control techniques developed by the sub-projects B3, B4 and B6 will be used for a flight relevant test configuration in VMK. There will be a strong cooperation with the sub-project B5 in terms of numerical simulation of the experiments.
