Abstract

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, Ahead of Print.
The variable working conditions faced by different flight stages in the whole process of hypersonic flight put forward different requirements for the aerodynamic shape of the aircraft. This paper presents a decoupled multi-stage extension and arbitrarily ...
