FAA JT3D QUIET NACELLE RETROFIT FEASIBILITY PROGRAM. VOLUME I-1. LOWER GOAL DESIGN, FABRICATION, AND GROUND TESTING

The work accomplished in Phase 1 of this contract included design, fabrication, and ground testing of a flightworthy quiet nacelle which satisfied the FAA lower goal for noise reduction of JT3D powered 707 aircraft. The quiet nacelle configuration consisted of a two-ring acoustically treated inlet, new fan thrust reverser, 3/4 length acoustically treated fan ducts, and revised contour aft translating sleeve. The configuration retained the standard primary thrust reverser and engine tailpipe. The quiet nacelle was ground tested to determine acoustic and performance data. Production JT3D nacelles were similarly tested thus providing a baseline whereby comparisons of acoustic and propulsion performance could be made. (Modified author abstract)
