This book was released on 1955 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been made in the Langley transonic blowdown tunnel at Mach numbers between 0.84 and 1.32 at an angle of attack of zero degrees to determine the pressure-drag reductions attainable on a sweptback-wing - fuselage configuration tested consisted of a 45 degree sweptback wing of aspect ratio 4 in combination with a fineness-ratio-6.7 body. The results indicate that the pressure drag of a practical sweptback-wing - body configuration depends on the body cross-sectional shape as well as upon the longitudinal distribution of cross-sectional area.

Available in PDF, EPUB and Kindle. Book excerpt: Progress in Aeronautical Sciences, Volume 3 deals with topics in the field of aerodynamics. The book covers topics on aerodynamic design, propulsion systems, hypersonic flows laboratories, and gust research. The text is composed of four articles. The first article presents a review of the aspects of aerodynamic design of swept-winged aircraft. The second paper surveys the applications of ducted propellers. Critical reviews of experimental hypersonic facilities are provided in Chapter 3. The last paper focuses on the meteorological and aeronautical aspects of atmospheric turbulence. Aeronautical engineers, pilots, aviators, and students in the field of aerodynamic design will find this book invaluable.

This book was released on 1960 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: A free-flight rocket-propelled-model investigation was conducted at Mach numbers of 1.2 to 1.9 to determine the longitudinal and lateral aero-dynamic characteristics of a low-drag aircraft configuration. The model consisted of an aspect-ratio -1.86 arrow wing with 67.5 deg. leading-edge sweep and NACA 65A004 airfoil section and a triangular vertical tail with 60 deg. sweep and NACA 65A003 section in combination with a body of fineness ratio 20. Aerodynamic data in pitch, yaw, and roll were obtained from transient motions induced by small pulse rockets firing at intervals in the pitch and yaw directions. From the results of this brief aerodynamic investigation, it is observed that very slender body shapes can provide increased volumetric capacity with little or no increase in zero-lift drag and that body fineness ratios of the order of 20 should be considered in the design of long-range supersonic aircraft. The zero-lift drag and the drag-due-to-lift parameter of the test configuration varied linearly with Mach number. The maximum lift-drag ratio was 7.0 at a Mach number of 1.25 and decreased slightly to a value of 6.6 at a Mach number of 1.81. The optimum lift coefficient, normal-force-curve slope, lateral-force-curve slope, static stability in pitch and yaw, time to damp to one-half amplitude in pitch and yaw, the sum of the rotary damping derivatives in pitch and also in yaw, and the static rolling derivatives all decreased with an increase in Mach number. Values of certain rolling derivatives were obtained by application of the least-squares method to the differential equation of rolling motion. A comparison of the experimental and calculated total rolling-moment-coefficient variation during transient oscillations of the model indicated good agreement when the damping-in-roll contribution was included with the static rolling-moment terms.
