To improve the understanding of the nozzle lifetime TP D9 will exploit the test stands developed in the 2nd FP for reliable experiments with innovative measuring comprising the hot gas flow, defining the heat flux to the structural surface, the nozzle structure, interacting with hot gas and coolant flow, and the flow inside the cooling ducts, convecting the heat from the metallic walls. A focus of work is now a doubling of the com-bustion pressure, to reach significantly higher heat fluxes. The influence of the surface roughness on heat transfer (hot gas and cooling duct side) will be analyzed. Finally, the application of thermal barrier coatings will show the improvement regarding damage protection.

为了提高对喷管寿命的理解，TP D9将利用第二FP开发的试验台进行可靠的实验，并进行创新的测量，包括热气流，确定结构表面的热通量，喷管结构，与热气流和冷却剂流相互作用，以及冷却管道内的流动，从金属壁对流热量。现在的工作重点是将com-bustion压力加倍，以达到显着更高的热通量。将分析表面粗糙度对热传递（热气体和冷却管道侧）的影响。最后，热障涂层的应用将显示关于损伤保护的改进。
