Beschreibung
Zusammenfassung:	The invention discloses a hydrodynamic seals in bearing compartments of gas turbine engines. In one aspect, the present disclosure is directed to a bearing compartment sealing system including a bearing for supporting a shaft. A housing encloses the bearing and defines a compartment for holding lubricant therein. At least two seals are located between the shaft and the housing. The at least two seals, the housing, and the shaft collectively enclose the compartment. Only one of the at least two seals is a hydrodynamic seal. 在方面，本公开内容针对种包括用于支承轴的轴承的轴承隔间密封系统。壳体包围轴承且限定用于将润滑剂保持在其中的隔间。至少两个密封件位于轴与壳体之间。至少两个密封件、壳体和轴共同地包围隔间。至少两个密封件中的仅个为水力密封件。
