Gas ingestion mechanism and unsteady flow characteristics of fish-mouth rim seals in an axial gas turbine

Rim seals fitted between the turbine stator and adjacent rotor disc, together with sealing air bled from compressor to pressurize the wheel-space, serve to suppress hot gas ingestion from mainstream in axial gas turbines. This paper investigates the distributions of pressure, swi...

Investigation of Oil Scavenging Characteristics and Structural Optimization of Bearing Chambers In Aero-Engines

Abstract Driven by the goal of carbon neutrality, efficient oil circulation in aero-engine lubrication systems is essential for reducing carbon emissions and promoting green aviation. This study investigates the oil scavenging characteristics of an innovative ramp-type bearing ch...
