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 ...

A Class of Three-Dimensional Optimum Wings in Hypersonic Flow [PDF]
, 1967 The idea of using streamlines of a certain known flow field to construct generally three-dimensional lifting surfaces together with the method of evaluating the aerodynamic forces on the surfaces, developed by Nonweiler, Jones and Woods, has been ...

Hypersonic control effectiveness
, 1995 The present study analyses the effects of a number of geometric parameters on the performance of a trailing edge control flap on a hypersonic body. The tests were conducted in a gun tunnel at Mach 8.2 and Mach 12.3.

Unstart Coupling Mechanism Analysis of Multiple-Modules Hypersonic Inlet
The Scientific World Journal, 2013 The combination of multiplemodules in parallel manner is an important way to achieve the much higher thrust of scramjet engine. For the multiple-modules scramjet engine, when inlet unstarted oscillatory flow appears in a single-module engine due to high ...

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.

Investigation of Flow Control for the Hypersonic Inlets via Counter Flow
International Journal of Aerospace Engineering, 2015 Experimental results show that there exist two flow fields in the hypersonic inlets when the forebody waves interact with the lip boundary, which is similar to the shock reflection ion hysteresis phenomenon.

Modeling and analysis for dynamical Doppler shifts on terahertz communication signals propagating in inhomogeneous hypersonic plasma sheath [PDF]
AIP AdvancesPrevious studies have shown that terahertz (THz) signals could penetrate hypersonic plasma sheaths. Thus, it is considered to be a potential solution to the “blackout” problem.
