Improvement of the Parallel Compressor Model and Application to Inlet Flow Distortion
International Journal of Turbomachinery, Propulsion and Power, 2021 This paper introduces a semi-analytical approach which enables one to deal with distorted inflow in axial fans or compressors. It is inspired by the classical parallel compressor (PC) theory but relies on a local flow-loading coefficient formalism. It is

Non-Axisymmetric Stator Design for Boundary Layer Ingesting Fans [PDF]
Volume 1: Aircraft Engine; Fans and Blowers; Marine; Honors and Awards, 2017 In a Boundary Layer Ingesting (BLI) fan system the inlet flow field is highly non-uniform. In this environment, an axisymmetric stator design suffers from a non-uniform distribution of hub separations, increased wake thicknesses and casing losses. These additional loss sources can be reduced using a non-axisymmetric design that is tuned to the radial ...

Design and Optimization of a Boundary Layer Ingesting Propulsor
Volume 2A: Turbomachinery, 2020 Abstract The boundary layer ingestion concept has the potential to improve propulsion efficiency that will lead to better fuel economy of commercial aircraft. This design concept has been explored by NASA as the Single-aisle Turboelectric Aircraft with Aft Boundary-Layer propulsor “STARC-ABL.” This paper discusses the 1D-3D aerodynamic ...

Stall Inception in a Boundary Layer Ingesting Fan [PDF]
Volume 2A: Turbomachinery, 2015 Jet engines with Boundary Layer Ingestion (BLI) could offer significant reductions in aircraft fuel burn compared with podded turbofans. However, the engine fans must run continuously with severe inlet distortion, which is known to reduce stability. In this paper an experimental study has been completed on a low-speed rig fan operating with a BLI-type ...
