FAA JT3D QUIET NACELLE RETROFIT FEASIBILITY PROGRAM. VOLUME III. LOWER GOAL FLIGHT TESTING, ECONOMIC ANALYSES AND SUMMARY

The Phase 1 quiet nacelle includes a two-ring acoustically treated inlet, hydraulically powered fan thrust reverser, 3/4 length acoustically treated fan ducts, and revised contour aft translating sleeve. The nacelle retains the standard Boeing 707 primary thrust reverser and tailpipe. An extensive ground test program, both model and full-scale was conducted to establish acoustic and propulsion performance and to confirm the adequacy of the design of the Phase 1 quiet nacelles. Four Phase 1 quiet nacelles were installed on a leased 707-331B airolane. flighs tests were conducted to determine far 36 type acoustic data anc fuel mileage of she quiet nacelle configured aircrafs. Subsequens to she quiet nacelle ohase of flying, the airolane was reconfigured to she standarc configuration anc a similar series of tests were performed thereby permitting a 'back-to-back' comparison.
