A Study of Hypersonic Aircraft [PDF]
Journal of the Aero-Space Transport Division, 1964 Possible characteristics and requirements of future hypersonic aircraft, as determined from a current NASA Flight Research Center study, are examined. The effect of hypersonic speed on range is shown to offer sufficient potential to warrant serious consideration for future missions.

Hypersonic Similarity for the Two Dimensional Steady Potential Flow with Large Data [PDF]
arXiv, 2019 In this paper, we establish the first rigorous mathematical global result on the validation of the hypersonic similarity, which is also called the Mach-number independence principle, for the two dimensional steady potential flow. The hypersonic similarity is equivalent to the Van Dyke's similarity theory, that if the hypersonic similarity parameter $K$

Light modulation in phoxonic nanocavities [PDF]
, 2011 We report on the occurrence of strong nonlinear acousto-optic interactions in phoxonic structures, that support, simultaneously, acoustic and optical localized resonant modes, under the influence of acoustic losses.

Lateral Stability Analysis of Hypersonic Vehicle under Pressure Fluctuation by Solving Mathieu Differential Equation [PDF]
arXiv, 2012 Two recent test failures of Hypersonic Technology Vehicle 2 impose a strike to the increasingly growing enthusiasm, not only on the United States side. It is important to find out the exact failure reason, otherwise a solution is impossible. In this Note, we propose a potential failure reason from the perspective of lateral stability analysis. We argue

Modeling radio communication blackout and blackout mitigation in hypersonic vehicles [PDF]
arXiv, 2014 A procedure for the modeling and analysis of radio communication blackout of hypersonic vehicles is presented. The weakly ionized plasma generated around the surface of a hypersonic reentry vehicle is simulated using full Navier-Stokes equations in multi-species single fluid form.
