摘要
柔性气动减速技术是航天器高速进入地外天体或再入地球大气安全着陆的关键核心技术,随着中国载人航天和深空探测等重大任务的持续推进,航天器更快的进入速度和更重的载荷对于高速柔性气动减速器的需求日益迫切.而高速柔性气动减速器的力学模型兼具强非线性和强耦合特性,且涉及研究领域极广,如需考虑钝性和多孔结构的气动特性、非线性结构动力学、可压缩湍流、结构气动热及其相互耦合等问题.因此,开展高速柔性气动减速器的基础理论和关键技术研究具有极大的难度和复杂性但意义重大.首先对高速柔性气动减速器进行分类;然后分析梳理了高速柔性气动减速技术的技术内涵,并系统地回顾和综述了其关键技术的发展历史和研究进展;最后,对高速柔性气动减速器关键技术的未来发展方向和亟需解决的关键问题进行了总结展望.
Abstract
Flexible aerodynamic deceleration technology is extremely key for spacecraft to safely land in extraterres-trial objects or re-enter the Earth's atmosphere at high speeds.With the continuous advancement of major missions such as Chinese manned spaceflight and deep space exploration,the demand for high-speed flexible aerodynamic de-celerator for spacecraft with faster entry speeds and heavier loads is becoming increasingly urgent.However,the me-chanical model of high-speed flexible aerodynamic decelerator combines strong nonlinearity and strong coupling char-acteristics,and involves a wide range of research fields,such as the aerodynamic characteristics of blunt and porous structures,nonlinear structural dynamics,compressible turbulence,structural aerodynamic heat and their mutual cou-pling issues.Therefore,conducting research on the fundamental theory and key technologies of flexible aerodynamic decelerators is of great difficulty and complexity,but of great significance.This paper,first,classifies the high-speed flexible aerodynamic decelerators.Then,the technical content of high-speed flexible aerodynamic decelerator technol-ogy is analyzed and sorted out,and the development history and research progress of its key technologies are system-atically reviewed and summarized.Finally,a summary and outlook are provided on the future development directions and key issues that urgently need to be addressed for the key technologies of high-speed flexible aerodynamic decelerators.
