FAA JT3D QUIET NACELLE RETROFIT FEASIBILITY PROGRAM. VOLUME 1-2. LOWER GOAL SYSTEM AND COMPATIBILITY TESTS
The Phase 1 quiet nacelle for JT3D powered 707 aircraft 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 707 primary thrust reverser and engine tailpipe. Full scale and model testing of the Phase 1 nacelle were accomplished to determine engine/nacelle performance and the adequacy of new or extensively revised systems. Acoustic tests were performed to determine the efficacy of the acoustic system after extended engine operation. Tests were performed by Pratt and Whitney Aircraft to confirm the compatibility of the Phase 1 quiet nacelle and the JT3D-3B engine. (Author)
