Review of high-speed flexible aerodynamic decelerators key technologies
摘要
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.关键词
