A Data‐Driven Approach to Integrated Adaptive Morphing and Guidance for Cruise Missiles

International Journal of Mechanical System Dynamics, Volume 5, Issue 4, Page 670-693, December 2025.
ABSTRACT To address the complex coupling between aerodynamic characteristics and guidance control for morphing flight missiles, this study proposes a data‐driven approach to integrated adaptive morphing and guidance. Firstly, an aerodynamic surrogate model is constructed using a fully connected neural network (FCNN), mapping the configuration ...

Design of Base Flow for Streamline-Traced Hypersonic Inlet

, 2009
A design methodology has been developed for the base flow of streamline-traced hypersonic inlet. Limited by the inlet length, the truncated Busemann flow results in a curved shock wave accompanied with large total pressure loss near the axis.

Combustion synthesis of ultra‐high temperature ceramics: Review

International Journal of Applied Ceramic Technology, Volume 22, Issue 6, November/December 2025.
Abstract Novel and future‐oriented aerospace, energy, transportation, and other industrial technologies require materials capable of operating at temperatures above 2000°C. Ultra‐high temperature ceramic materials (UHTCs), based on carbides, borides, carbonitrides, and nitrides of transition metals—many with melting points exceeding 3000°C—possess the ...

Three-dimensional characteristics of separation vortex generated by crossing shock/boundary layer interaction

AIP Advances
Three-dimensional shock/boundary layer interactions (SBLIs) in the hypersonic inlet generate the separation vortex, which affects the flow uniformity of the inlet and can even cause the inlet to unstart.

Brazing ZrB2 ultra‐high‐temperature ceramics to Zr metals for hypersonic thermal protection systems

International Journal of Applied Ceramic Technology, Volume 22, Issue 5, September/October 2025.
Abstract Porous and dense zirconium diboride (ZrB2) materials are promising ultra‐high‐temperature ceramics (UHTCs) for transpiration cooling in hypersonic applications, providing an effective means to reduce component temperatures and mitigate oxidation effects. While porous ZrB2 enables coolant flow, dense ZrB2 offers structural integrity.
