The author (SMH) thanks the DoD SMART program for his sponsorship as well, with Mr. Terence Ghee serving as program mentor. Special thanks are extended to Dr. Leighton Myers, Mr. Frank Taverna, Mr. Joshua Butler, and Ms. Robin Imber of NAVAIR Patuxent River for providing invaluable guidance and technical input on the design of the dual-stream rectangular jet model. Finally, development of the dual-stream model would not have been possible without the machining services provided by Mr. Philip Irwin previously of the PSU Mechanical Engineering Department and Mr. Matthew Stanley of NAVAIR Patuxent River.

N2 - Multi-stream, variable cycle point, low bypass ratio, turbofan engines are in consideration for future tactical aircraft. Such engine architectures aim to cycle between high-thrust and high-efficiency operation as required by the demands of the flight profile. Integration of the nozzles with the aircraft fuselage can introduce new design components including aft decks downstream of the nozzle exit. It is necessary to gain further insight into what effects of aft decks have on the noise radiated from dual-stream, rectangular jets. This work reports on a series of far-field acoustic measurements of dual-stream jets with and without aft decks to better understand the effects these features have on the radiated noise.
