Flutter investigation at low speed of a 40 degree sweptback wing with pylon-mounted stores, tested as a semispan-cantilever wing and as a full-span wing on a towed airplane model /

Wind-tunnel flutter investigations at Mach numbers up to 0.30 have been conducted on a 40 degree sweptback wing having pylon-mounted stores located at 73.5 percent of the semispan. The investigations were conducted on a semispan-cantilever wing with root fixed and with the full-span wing mounted on an autopilot-controlled model of a fighter-type airplane flown on the end of a towline. The store loadings were varied from 55 to 88 percent of the wing-panel weight, and the store pitch inertias were varied from 66 to 181 percent of the wing-panel pitch inertia. Most of the data were obtained with the store centers of gravity located at 15 percent of the local wing chord.NACA Research Memorandum L56F14A."September 7, 1956."Title from cover.Includes bibliographical references (p. 15).Wind-tunnel flutter investigations at Mach numbers up to 0.30 have been conducted on a 40 degree sweptback wing having pylon-mounted stores located at 73.5 percent of the semispan.
