First Order Correction

The pressure coefficient is found by the acoustic theory for a class of slender bodies in uniform acceleration or deceleration to a given Mach number, subsonic or supersonic. Explicit formulas for the main pressure term, and for the first-order correction caused by the unsteady motion, are obtained for bodies which are perturbations from the basic parabolic profile. Examples are given of bodies contained in this theory, together with typical pressure-coefficient curves. Methods are given for selecting a pointed convex profile having its maximum cross section at any desired point lying within certain limits.

Abstract. Application of the Brown-Samelson theorem, which shows that particle motion is integrable in a class of vorticity-conserving, two-dimensional incompressible flows, is extended here to a class of explicit time dependent dynamically balanced flows in multilayered systems. Particle motion for nonsteady two-dimensional flows with discontinuities in the vorticity or potential vorticity fields (modon solutions) is shown to be integrable. An example of a two-layer modon solution constrained by observations of a Gulf Stream ring system is discussed.
