Application of Tribology in Aircraft Engine Sealing Technology
نویسنده
چکیده
The seals are the important component of the aircraft engine to prevent leakage of gas or oil. Because the contact and friction problems have a great influence on the performance of the seals, the concept and theory of tribology is already widely applied in research and design processes of advanced seals. This report selected three kinds of representative seals which are commonly used on the modern aircraft engines as the research object: labyrinth seals, brush seals and mechanical face seals. The principles of every kind of seals will be analyzed from the tribology viewpoint. The concept and theory of tribology will also be applied in solving the contact and friction problems which limit the performance and the service life of seals. Thus reveals the close connection between the tribology and the aircraft engine sealing technology.
