Book Description
Tables are presented containing 69,000 values of a set of characteristic functions which first arose in problems of supersonic wing-body interference. The tables are useful in problems of supersonic flow involving aerodynamic shapes which are wholly or in part quasi-cylinders of nearly circular cross section. A number of uses are described in the aerodynamics of bodies alone, body-body or shock-body interference, wing-body interference, the vortex-panel interference. Three illustrative examples are worked out in detail. First, the pressure field due to fuselage indentation is calculated and presented in a form independent of Mach number. Secondly, the tables are applied to a problem involving a previously unpublished solution to the Navier-Stokes equations; namely, the boundary-layer profiles of a circular cylinder moved impulsively with a constant axial force in a viscous incompressible fluid. In the final example, the wave drag of corrugated circular cylinders is calculated as a function of the number of corrugations and their wave length. Several nonaerodynamic applications are pointed out in the fields of acoustics and heat conduction. Generally speaking, the tables are applicable to boundary-value problems of the second kind involving the wave equation in three dimensions with approximately circular cylindrical boundaries or involving the unsteady heat-conduction equation in two space dimensions with nearly circular boundaries.

Book Description
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.
