Asymmetric vortices on a slender body of revolution
28th Aerospace Sciences Meeting, 1990The symmetric and asymmetric leeward-side flow fields on an inclined ogive-cylinder have been investigated using a number of experimental techniques. Naturally occurring and perturbed flow fields were studied at a moderate Reynolds number and at many incidence angles. By close examination of the steady side force behavior at different roll orientations

Generalized Convex Bodies of Revolution
Canadian Journal of Mathematics, 1967The figures studied in this paper are special convex bodies in Euclidean three-dimensional space which we shall call generalized convex bodies of revolution (GCBR). Such a set is obtained by the following procedure. Let K1 be a convex body of revolution and let x, y, z denote Cartesian coordinates in a system for which the z-axis is the axis of K1.

Abstract : A method of solution for the aerodynamic flow field about two bodies at angle of attack including mutual interference effects has been devised for bodies with circular cross-section. The analytical method used is a modification of a method of solution for the flow about axisymmetric bodies in close proximity at zero angle of attack.

A Further Study of Bodies of Revolution
Journal of Ship Research, 1978The use of a body of revolution is considered as a model of reflex ship forms, for the estimation of skin friction. The model examined was that proposed by Matheson and Joubert [1], and is based on equality of lengthwise perimeter variation between the hull reflex geosim and the body of revolution.

Improved Bodies of Revolution.
1981Abstract : The aperture loading technique (ALT) is implemented in an aperture coupling body of revolution (BOR) computer code. Apertures of material fill (dielectric, composite, conductive putty, etc.) are amenable to ALT analysis. Thin apertures formed from complex shaped walls, e.g., sleeve-fit seams, also are amenable to ALT analysis.

Hypersonic Flow Around Bodies of Revolution
Journal of the Aerospace Sciences, 1961In a paper in this issue of the Aerospace Sciences, the relative importance of radiation and convection energy transfer is discussed in the case of stagnation flow at hypersonic speeds. Air emissivities are obtained from convenient tables, and radiation fluxes are illustrated for a wide range of altitude and velocities.

On the equilibrium of piezoelectric bodies of revolution
International Journal of Solids and Structures, 2000Using previously established three-dimensional general solutions for piezoelectric bodies of revolution, the authors investigate two classes of such bodies: the circular plate (or cylinder), and the cone. A series of analytical solutions is established under different mechanical and electric loadings, including the circular plates or cylinders under ...

Scattering by slender bodies of revolution
The Journal of the Acoustical Society of America, 1982The pressure scattered by slender bodies of revolution irradiated by a plane wave at ‘‘beam aspect’’ is formulated in a manner which relaxes the assumptions underlying the Kirchhoff analysis. While the latter stipulates that area elements scatter as though located in planar baffles, the present theory assumes that the baffles are cylindrical, i.e ...

Aperture coupling in bodies of revolution
IEEE Transactions on Antennas and Propagation, 1978A method for predicting the field penetrating a circumferential opening in a body of revolution is described here. This method employs the method of moments and an aperture equivalence theorem. The former permits rotationally symmetric cavities with otherwise arbitrary contours. The latter improves the sensitivity of field computation when the aperture
