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

Characteristics of unsteady total pressure distortion for a complex aero-engine intake duct [PDF]
Aerospace Science and Technology, 2018 Some types of aero-engine intake systems are susceptible to the generation of secondary flows with high levels of total pressure fluctuations. The resulting peak distortion events may exceed the tolerance level of a given engine, leading to handling ...

Simulation and Study on Plate-Type Total Pressure Distortion Simulators [PDF]
Proceedings of 2016 International Conference on Modeling, Simulation and Optimization Technologies and Applications (MSOTA2016), 2016 In China, plate-type total pressure distortion simulators are widely used for carrying on inlet total pressure test of compressing systems of aeroengine. In this article modeling and simulating were imposed on this type of simulators.
