摘要

Hypersonic flight has been with us since 22 September 1963, when Robert M. White flew the North American X-15 at 4520 mph at an altitude of 354, 200 ft-a Mach number of 6.7! This remarkable achievement was accomplished over six decades due to intensive research and development by a large number of scientists and engineers. In spite of that momentous achievement, designers have found the hypersonic environment to be harsh and non-forgiving. New programs since the 1960s have often uncovered the unknown unknowns, usually the hard way-early flights of new systems have often revealed problems of which the designers were unaware. Such problems include: the ineffectiveness of the body flap for the Space Shuttle Orbiter, the viscous/inviscid interactions produced by the umbilical fairings that damaged the conical section tile protection system of the Gemini Capsule, and the shock/shock interaction that damaged the X-15A-2 when it carried the hypersonic ramjet experiment. In order to continue to make advances in hypersonic flight a sustained and visionary effort is essential to generate required knowledge and technology. In order to better prepare for future developments in hypersonic flight, this article reviews the advances made within the past 50 years and then looks into the future, not just for new technological developments, but for new ways of thinking about the unknown challenges that lie ahead.

White)以4520英里/小时的速度在354、200英尺马赫数6.7的高空飞行北美X-15!由于众多科学家和工程师的深入研究和开发,这项非凡的成就在过去的六十年中得以实现。尽管取得了这一重大成就,设计师们还是发现超音速环境是严酷且不容忍的。自1960年代以来的新程序经常发现未知的未知数,通常新系统的艰苦早期尝试常常揭示出设计人员未意识到的问题。这些问题包括:航天飞机轨道飞行器的襟翼无效,脐带整流罩产生的粘性/无粘性相互作用破坏了双子座胶囊的圆锥形截面保护系统,以及冲击/冲击相互作用破坏了X-图15A-2进行了超音速冲压发动机实验。为了继续在高超音速飞行中取得进展,持续而有远见的努力对于产生所需的知识和技术至关重要。为了更好地为高超音速飞行的未来发展做好准备,本文回顾了过去50年中取得的进展,然后展望了未来,不仅是针对新技术的发展,还包括了思考未来未知挑战的新方法。 。
