本文介绍了关键的历史贡献，现状和未来的研究途径，以支持超音速飞机的发展，足够安静，使他们可以在陆地上超音速飞行。为了实现这一目标，除了克服空气动力学、结构、推进、声学和气动伺服弹性方面的许多其他挑战外，飞机产生的压力信号必须是这样的，当它到达地面时，（a）它几乎不能被人耳感知，以及（B）它导致对人造结构的干扰，该干扰不超过对相当大比例的人口的烦扰阈值。换句话说，地爆信号必须满足一些可以适当量化的关键限制。在设计具有低音爆的飞机时，重要的是要了解（a）压力扰动是如何产生的，以及它们是如何在大气中传播的，（B）在什么条件下飞机产生的压力信号将演变成在地面上产生可接受的低音爆信号，以及（c）需要进行哪些多学科的权衡来实现低吊杆飞机，这些飞机也是经济和环境兼容的。本文将分别讨论这些领域，评估每个主题的成就，确定重大缺陷，并建议未来的研究工作（一些已经在进行中），有可能产生解决所有这些问题的方案。
This article presents a review of key historical contributions, the current status, and future research avenues in support of the development of supersonic aircraft that are sufficiently quiet so that they can be allowed to fly supersonically over land. For this goal to be achievable, in addition to overcoming many other challenges in aerodynamics, structures, propulsion, acoustics, and aeroservoelasticity, the pressure signature created by the aircraft must be such that, when it reaches the ground, (a) it can barely be perceived by the human ear, and (b) it results in disturbances to man-made structures that do not exceed the threshold of annoyance for a significant percentage of the population. In other words, the ground-boom signature must meet a number of key constraints that can be appropriately quantified. In designing aircraft with low sonic booms, it is important to understand (a) how pressure disturbances are generated and how they propagate through the atmosphere, (b) under which conditions will the pressure signature created by an aircraft evolve to generate an acceptable low-boom signature at the ground, and (c) what multidisciplinary trade-offs need to be made to realize low-boom aircraft that are also economically and environmentally compliant. This article discusses each of these areas separately, assesses the accomplishments in each topic, identifies significant shortcomings, and suggests future research efforts (some already ongoing) that have the potential to yield solutions to all these issues.
