It is foreseen to consolidate open issues of the GOX/GCH4 combustion studies and find an injector config-uration with sufficient performance, acceptable wall heat loads and minimum film cooling flow rates and a more detailed investigation of a natural combustion instability which occurred during phase 2. The adapta-tion of the facility with liquid oxygen and the repetition of selected tests with liquid oxygen will deepen the established data base for injector performance, wall heat transfer and film cooling efficiency. The main objective is a data base for the validation of detailed scientific approaches developed within the SFB TRR 40 in SP C1, and C5 and for the improvement of existing engineering design tools.

可以预见的是，要巩固GOX/GCH 4燃烧研究的公开问题，并找到具有足够性能、可接受的壁热负荷和最小气膜冷却流率的喷射器结构，并对第2阶段期间发生的自然燃烧不稳定性进行更详细的研究。液氧装置的改造和液氧试验的重复性，将加深已建立的喷注器性能、壁面传热和气膜冷却效率的数据库。主要目标是为验证SFB TRR 40 SP C1和C5中开发的详细科学方法以及改进现有工程设计工具提供数据库。
