A Unified Asymptotic Theory of Supersonic, Transonic, and Hypersonic Far Fields
Axioms, 2022 The problems of steady, inviscid, isentropic, irrotational supersonic plane flow passing a body with a small thickness ratio was solved by the linearized theory, which is a first approximation at and near the surface but fails at far fields from the body.

Two-dimensional film cooling over a flat plate in hypersonic flow
Propulsion and Power Research, 2018 Film cooling, as one efficient active cooling method, will hopefully be used in ‘hypersonic vehicles’ in the future. The hypersonic vehicle׳s surface is more likely a flat plate than a blunt body, so the cooling characteristics of two-dimensional (2-D ...

A Proposal for Long-Term Missions of Small Lunar Rovers Using an MLI Curtain System
International Journal of Aerospace Engineering, 2019 This paper proposes a lunar night survival method for small rovers using an MLI (Multilayer Insulation) curtain system for long-term missions. Until recently, it was difficult to install RHU (Radioisotope Heating Units) or other temperature maintenance ...

Self-Start Characteristics of Hypersonic Inlet When Multiple Unstart Modes Exist
Applied Sciences, 2023 Intense shock boundary-layer interaction may lead to multiple unstart modes existing in a hypersonic inlet. Thus, self-start problems become complex and cannot be explained using the classical double-solution theory of air inlet.
