Abstract: Straight-through labyrinth seals are reliable noncontact seal structures widely used in aeroengines. Windage heating and swirl development of labyrinth seals are of great significance to the design of secondary air systems. ...

Abstract: This study investigates an onboard aeroengine model (OBEM)-tuning system (OTS) based on a hybrid Kalman filter, which is mostly used to estimate the aeroengine performance. The OTS structure comprises two parts. One is an ...

Abstract: This paper presents a hybrid model-based fault diagnosis system to distinguish different types of faults and provide accurate fault information under complex fault situations. In the proposed system, a bank of hybrid fault ...

Abstract: The secondary air system of a gas turbine engine is a complex fluid network that is sensitive to geometric variations in the flow elements caused by manufacturing, assembly, and operating conditions. Geometric uncertainty ...

Abstract: Experimental investigations were performed to measure the local heat transfer coefficient (hg) distributions of film cooling over a flat blade under both stationary and rotating conditions. Film ...
