摘要
介绍了石墨圆周密封、刷式密封、指状密封、气膜密封和其他几种新型密封技术研究的新进展和在航空发动机上的应用,对密封技术的机理、特点和在研究中遇到的问题进行了分析和讨论。阐明了为适应航空发动机的发展要求,密封技术应进行材料、工艺、结构、机理等多方面的开创性设计,并提出在密封技术设计中应引入控制概念的观点。
The development and application of aeroengine seal technology were introduced, which include high misalignment carbon seals, brush seal, finger seal, film sealand other new kinds of seal technology. The principles, characteristics, problems were analyzed and discussed. The innovative design on materials, process, structures and principles of seal technology should be conducted to meet aeroengine development requirements and the views of control concept were introduced in seal technology design.
