TL;DR: In this article, a survey of the present knowledge about the instability of free shear layers which occur in jets is given, where the main interest is focused on the instability and the influence of variable basic density distribution and of Mach number.

TL;DR: In this paper, the authors have studied the conical streamlines formed by the intersection of the concave stream surfaces of a conical flow with a sphere centred at the vertex of the flow and discussed the types of singular points which can arise in such a pattern.

TL;DR: In this paper, a critical appraisal is made of the design, research, development, and operation of the novel UTIAS implosion-driven hypervelocity launchers and shock tubes.

TL;DR: In this paper, the authors made two observations in the context of lifting re-entry: during reentry itself, much higher lift coefficients (both at maximum lift and per unit lift-drag ratio) can be provided by variants of the caret wing than by flat-bottomed delta wings or other vehicles that give high spillage.

TL;DR: The equations of motion pertinent to the study of steady and perturbed motions of a rigid vehicle flying on a minor circle at constant altitude above a spherical non-rotating earth are presented in this paper.

TL;DR: In this paper, the surface interaction problem of neutral monatomic gas interaction with a simple clean surface at energies 10−2−102 eV has been studied and a general statement of the problem and a brief review of the physical and computational data results are provided.

TL;DR: The theoretical background of the methods of plastic design can be found in any monography devoted to the mathematical theory of plasticity, see as mentioned in this paper for an overview of the theoretical background.

TL;DR: In this paper, a review of the specific conditions incident to ascent, and of the mathematical model generally adopted to represent the sounding rocket, the general equations of motion are set up, then simplified so as to enable each phenomenon to be studied on its own merits.
