A review on aero-engine inlet-compressor integration and inlet flow distortion in axial compressors
Fundamental ResearchThe air intake-compression systems of modern aircraft usually use the aero-engine intake and fan/compressor as the main components. Inlet-engine compatibility has always been the key to the stable and safe operation of the propulsion system, including ...

Numerical simulation of S-shaped inlet under the intake total pressure distortion [PDF]
MATEC Web of Conferences, 2022 During the development of the stealth fighter, the S-shaped inlet enters the designer’s vision because it has better stealth than bump inlet and straight inlet. During the use of the S-shaped inlet, due to its structural reasons, secondary flow is likely

Using Tip Injection to Stability Enhancement of a Transonic Centrifugal Impeller with Inlet Distortion [PDF]
Journal of Applied Fluid Mechanics, 2022 This paper aims to understand the effects of circumferential inlet distortion and tip injection on a transonic impeller performance and flow field. For distorted inflow, the impeller is subjected to a stationary 120-degrees circumferential total pressure
