Flight performance of auxiliary inlet ejector and plug nozzle at transonic speeds

R. R. Burley

Open full text 2 citations

Abstract

Nozzle performance may be sensitive to the type of airframe-nozzle installation.An installation that is of general interest is a podded engine mounted near the aft lower surface of the wing.The effect of this installation on nozzle performance in the transonic speed range is currently being investigated at the Lewis Research will discuss some of the significant results obtained with two of these nozzle types: auxiliary inlet ejector and conical plug.Both of them approximate subsonic cruise geometries of nozzles designed for efficient operation in the Mach 2.8 range.
