Structural and Cooling Aspects of the Aden Nonaxisymmetric Exhaust Nozzle

Abstract

The initial development of a nonaxisymmetric vectoring exhaust nozzle has been completed for the U. S. Navy by the General Electric Company. This exhaust system, called ADEN (Augmented Deflector Exhaust Nozzle), has been tested at GE’s Peebles, Ohio test facility using a YJ101 engine as the gas producer. This paper reviews the structural and cooling design of the ADEN nonaxisymmetric nozzle. Temperature and pressure data from the test series are compared to design intent for the nozzle operating in normal cruise and deflected (vectored) modes.

Performance of a 2D-CD nonaxisymmetric exhaust nozzle on a turbojet engine at altitude

“…Favorable results have been obtained in the full scale ADEN program (ref. 10) at sea level static test conditions. Tests over the full operating range at altitude, however, remain to be done.…”
