Abstract
A turbo-ramjet engine configuration has possible applications in missiles or Uninhabited Aerial Vehicle's (UAV's). In order to study possible configurations, a Sophia J450 turbojet engine was used, with varying shroud configurations, to compare static thrust and specific fuel consumption measured in a test rig. A baseline shroud, which covered the engine, was tested with three ducts lengths aft of the J450's exhaust. Bach duct length was tested with and without the final convergent nozzle. An elliptic intake for the shroud was also manufactured and tested on two of the configurations. Shroud pressures were also recorded to determine the amount of entrainment of secondary flow into the shroud. The short shroud was found to produce the best performance of the three configurations tested.
