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.

在即将到来的供资期间，分项目B1的主要目标是研究热羽流与跨音速区域外流的相互作用。不同配比的H_2O_2燃料可以在发射装置模型的基础上进行系统的空气动力学和气动现象研究。将使用金属和CMC喷管进行实验，研究壁温和热辐射对发射器底部区域气动干扰的影响。此外，由子项目B3、B4和B6开发的最有前途的被动和主动流动控制技术将用于VMK中与飞行有关的试验构型。在实验的数值模拟方面，将与分项目B5进行强有力的合作。
