摘要

本文在简述超声速民机(supersonic commercial transport---SCT)的发展历史后,介绍了正在研制的几种超声速公务机的特点,未来(2020-2035年间)超声速小型民机概念研究的进展及其可能的外形特点。由于降低音爆是当前发展SCT的首要任务之一,本文重点讨论了当前降低音爆的优化设计方法,包括:基于线性理论的设计方法;基于Euler解算器(Cart3D)和伴随方法的低音爆反设计方法;广义Burgers方程描述波的传播及其求解方法;以音爆造成地面噪声最小为目标,直接耦合音爆传播和CFD流场解的优化设计方法;可用于概念设计的多重优化设计方法等。

Abstract

Following a brief introduction of the development history of the supersonic commercial transport (SCT), the characters of several developing supersonic business jets are given. The conceptual design research of the small SCTs being served in the time period 2020-2035 and their possible configurations and features are described, too. Due to sonic boom reduction being one of the main tasks for developing SCT, some optimal design methods for reducing sonic boom are discussed in detail in the present paper, which are: the design method based on linearized theory; sonic boom mitigation method using inverse design of coupling Euler solver (Cart 3D) and adjoint method; the approach of advanced sonic boom prediction using augmented Burgers equation; the formulation that boom propagation and CFD are formally coupled for the purpose of obtaining gradients of a ground based objective with respect to the aircraft shape design variables; the optimization and adjoint-based CFD for the conceptual design of low sonic boom aircraft.
