Subscale Study of Engine Bellmouth Inlet Vortices in Test Cell R1D

Abstract

A technology program was conducted in Test Cell R1D concerning bellmouth flow quality. Flow visualization was used to determine the presence of inlet vortices. It was shown that these vortices can be eliminated using a 45-deg conical extension attached to the bellmouth inlet. Design guidelines were developed to assist in determining acceptable cone angles and axial and radial gaps between the conical extension and the bellmouth inlet. (AN)
