摘　　要：重点介绍了用于密封航空发动机主轴承腔的先进单环圆周密封装置的结构和性能设计特点,对几种关键设计方法进行了综合论述:首次提出了关于结构尺寸、加工精度、弹性元件弹性力与密封静态和动态性能相关的关联方程,可进行动、静态泄漏计算。The structure and performance design characteristics of single circumferential seal were introduced for sealing primary bearing cavity of aeroengine. Some critical design methods were described comprehensively. The correlation equation related to seal static and dynamic perfarmance about structure size, machining precision, elastic force of elastomeric components is presented firstly and it can calculate static and dynamic leakage.
