This book was released on 1960 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: Calculated responses of symmetrical airplane motions, wing deformations, and wing loads due to continuous turbulence are shown to compare favorably with available flight-test results. These calculated responses are based on random-process theory, five degrees of freedom, lifting-surface aerodynamics, and one-dimensional turbulence. Of the five degrees of freedom used only three, rigid-body translation and pitch modes and the first wing bending mode, are shown to contirbute significantly to the airplane responses over the frequency range considered (0 to 2 cps). Bending-moment amplification factors are presented in order to show the effects of dynamic aeroelasticity. These effects are found to increase the response by 35 to 115 percent, depending upon the spanwise station.

This book was released on 1956 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of an investigation in the Langley full-scale tunnel of the induced flow near a lifting rotor are given. Measurements of stream angles and velocities were made in several transverse planes along and behind the rotor in four different conditions representative of the cruising and high-speed ranges of flight. These measurements indicate that available theory may be used to calculate with reasonable accuracy the induced flow over the forward three-quarters of the disk for these flight conditions provided that a realistic nonuniform rotor disk-load distribution is assumed. Rearward of the three-quarter-diameter point, calculations of the induced velocity are increasingly inaccurate due to the rolling up of the trailing-vortex system. Farther rearward, well behind the rotor, the flow may be represented more accurately by the flow behind a uniformly loaded wing.

Available in PDF, EPUB and Kindle. Book excerpt: A series of tests of a 45 deg sweptback-wing model with and without fuselage and of an equivalent straight-wing model were conducted in the Langley gust tunnel to provide information on some of the problems encountered in the prediction of gust loads for airplanes incorporating swept wings. A comparison of test results with calculated results indicated that the maximum acceleration increment resulting from the penetration of a gust by a sweptback-wing airplane may be assumed to be dependent on the slope of the lift curve of the equivalent straight wing multiplied by the cosine of the angle of sweep, rather than on the steady flow slope of the lift curve. In addition, it appeared that the maximum acceleration increment also depends on the effect on the unsteady-lift function of the gradual penetration of the sweptback wing into the gust. A comparison of the maximum acceleration increments obtained for the swept-wing model with those obtained for the straight-wing model indicated that, although the airplane with a swept wing would show positive pitching motion, it would undergo a much lower acceleration increment than the same airplane with the equivalent straight wing.
