| Abstract: | 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. |
