对于未来的低排放航空发动机燃烧室，需要显著减少冷却空气消耗。燃烧室设计者需要在实际环境中先进冷却方案性能的定量数据以及现有的按比例等温研究数据，以便进一步改进。在这方面的贡献的冷却空气的性质对冷却效果的不同先进的冷却概念，在现实的操作条件下进行了介绍和分析。将特别讨论测量技术的适应和废气辐射的校正。本文介绍了基本的冷却设计注意事项。版权所有© 2008 ASME和Rolls Royce Ltd. & Co. KG
For future low emission aero engine combustors a significant reduction of cooling air consumption is required. Quantitative data of the performance of advanced cooling concepts in a realistic environment in addition to existing data from scaled isothermal investigations is needed by combustor designers for further improvements. In this contribution the effect of the cooling air properties on the cooling effectiveness of different advanced cooling concepts at realistic operating conditions is presented and analyzed. Adapting of the measuring techniques and correction of the exhaust gas radiation will be especially addressed. An introduction into basic cooling design considerations is included in the article.Copyright © 2008 by ASME and Rolls Royce Ltd. & Co. KG
