Book Description
The differential equations and boundary conditions appropriate to the analysis of torsional vibrations of hollow thin-walled cylindrical beams are presented. General solutions for the modes and frequencies of cantilever and free-free cylindrical beams of arbitrary doubly symmetrical cross section with uniform wall thickness derived. Numerical calculations for beams of rectangular cross section are used to determine the influence on torsional vibrations of bending stresses due to torsion and a longitudinal inertia. The inclusion of longitudinal inertia exposes a strong coupling of the torsional vibration with longitudinal vibrations at low plan-form aspect ratios, and some of the frequencies obtained are seen to be actually associated with modes of primarily longitudinal vibration. The solution for cylinders of rectangular cross section is also used to investigate the the accuracy of a solution obtained from an analysis of an equivalent four-flange box beam.

Experimental Study of the Equivalence of Transonic Flow about Slender Cone-cylinders of Circular and Elliptic Cross Section

Book Description
The results of the investigation suggest that at transonic speeds and at small angles of attack the calculation of all aerodynamic characteristics of slender, three-dimensional shapes can be made by use of transonic slender-body theory when the pressures on the equivalent body of revolution are Imown, either by experiment, or by an adequate nonlinear theory. From transonic slender-body theory it is deduced that the slenderness required for this application is the same as that required for the successful application of the transonic area rule.
