Flow field behind a complex total pressure distortion screen

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2019
The flow field behind a complex total pressure distortion screen is investigated experimentally and numerically. The distortion screen is designed using an established design methodology and fabricated by water-jet cutting technique. The distorted total pressure field behind the screen is quantified by a distortion index parameter, which is evaluated ...

Characteristics of unsteady total pressure distortion for a complex aero-engine intake duct [PDF]

Aerospace Science and Technology, 2018
Abstract 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 problems or to compressor surge. Previous work used distortion descriptors for the assessment

Effect Of Circumferential Total Pressure Distortion On Stability In An Axial Flow Compressor

Proceedings of Global Power & Propulsion Society, 2022
The effect of circumferential total pressure distortion on aerodynamic stability was experimentally investigated in an axial flow compressor. Different circumferential distorted inflow fields were generated with a flat-baffle installed upstream the compressor.

Investigation of Plenum Inlet Distortion and its Impact on Compressor Total Pressure and Swirl Distortion

Volume 2: Aircraft Engine; Coal, Biomass and Alternative Fuels; Cycle Innovations, 2013
Aircraft auxiliary power unit (APU) compressors experience a wide range of total pressure and swirl distortion levels as a result of the APU inlet geometry and different flight conditions and wind directions. Compressors are designed to operate with certain levels of distortion while avoiding surge and stall and maintaining acceptable stress levels ...

Inlet Total-Pressure-Distortion Considerations for Gas-Turbine Engines

2017
<div class="section abstract"> <div class="htmlview paragraph">This document addresses many of the significant issues associated with effects of inlet total-pressure distortion on turbine-engine performance and stability. It provides a review of the development of techniques used to assess engine stability margins in the presence of inlet
