Flow physics in a micro turbojet engine inter-shaft fuel supply system

Physics of Fluids
Inter-shaft fuel supply systems (ISFSSs) consisting of a shaft annulus and a fuel slinger are usually used in micro turbojet engines to pump the fuel to the combustor, aiming at reducing engine's size and weight. Differing from the configuration with stationary fuel pipework, the fast-rotating shaft in the annulus would induce significant drag ...

Vibration Analysis of a Micro Turbojet Engine under Two Impeller Structural Faults

Proceedings of Global Power & Propulsion Society
Disk fracture and locking nut loosening of centrifugal impeller leads to severe vibration of micro turbojet engines, posing significant threats to engine stability and safety. In order to identify the engine vibration characteristics induced by the above two faults in a practical micro aero-engine, vibration acceleration of the engine casing is ...

A study on the mixing and infrared signal characteristics of a lobed mixer in a micro turbojet engine

The Aeronautical Journal
AbstractIn this study, measurements and numerical analyses of the temperature distribution of exhaust gas passing through two types of mixers using a micro turbojet engine were performed to investigate the flow mixing performance based on the shape of the mixer, which mixes the bypass air and core air in a gas turbine turbofan engine.
