Aeromechanics Analysis of a Boundary Layer Ingesting Fan [PDF]
48th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2012 Boundary layer ingesting propulsion systems have the potential to significantly reduce fuel burn but these systems must overcome the challe nges related to aeromechanics-fan flutter stability and forced response dynamic stresses. High-fidelity computational analysis of the fan a eromechanics is integral to the ongoing effort to design a boundary layer ...

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 ...
