Book Description
Abstract: The effects of varying Reynolds number on the pressure distribution over a transonic body of revolution are presented. Angles of attack from -2° to 15° were investigated through a Mach number range from 0.60 to 1.09. The Reynolds number based on body length varied from 9 x 106 to 39 x 106, and on maximum diameter from 1.35 x 105 to 4.53 x 105. There were small effects of Reynolds number on the axial pressure distributions of these bodies. These effects were of such a nature as to cause an increase of 0.05 in the normal-force coefficient of the body when tested in the subcritical cross-flow Reynolds number range. A comparison between values of incremental pressure coefficient due to angle of attack and theoretical values was made.

Book Description
Progress in Aeronautical Sciences, Volume 8 is a collection of papers that covers the widening field of aeronautical sciences. The first article deals with problems in fluid mechanics and practical aerodynamics. This paper includes reducing problems to integral equations; the comparison of calculated results with exact analytic solutions; and with experimental pressure distributions using various configurations. The book follows this discussion with a review of the methods for designing swept-winged aircraft, including the design of a symmetrical-fuselage combination at zero incidence. The text also reviews the propulsion characteristics of a hypothetical aircraft flying at hypersonic speeds, and then focuses on air-breathing engines to power hypersonic aircrafts of which the scramjet is the most promising. The publication renders a comprehensive report on the viscous flow in boundary layers in ducts under rarefied conditions. The book then reviews investigations made on the viscous flow through tubes, both in continuum flow and in free-molecule flow. Another paper develops the fundamental mathematical and physical bases of magnetohydrodynamic flow through ducts in the presence of an applied electromagnetic field. Such review is useful when applied to electromagnetic flowmeters, pumps, or generators. The volume can be helpful for aerodynamic researchers, aviation technologists and designers, and aeronautical engineers.
