Theoretical prediction of high melting temperature for a Mo–Ru–Ta–W HCP multiprincipal element alloy

npj Computational Materials, 2021
While rhenium is an ideal material for rapid thermal cycling applications under high temperatures, such as rocket engine nozzles, its high cost limits its widespread use and prompts an exploration of viable cost-effective substitutes.

Investigations on an All-Oxide Ceramic Composites Based on Al₂O₃ Fibres and Alumina–Zirconia Matrix for Application in Liquid Rocket Engines

Aerospace, 2022
High performance ceramics, particularly Ceramic Matrix Composite (CMC) materials found their way into liquid rocket engines. Yet, so far, mainly carbide or nonoxide CMCs have been of interest.

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

Advanced Energy and Sustainability Research, EarlyView.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Air to ground rocket dispersion minimization [PDF]

Scientific Technical Review, 2018
Dispersion of the impact points of the unguided rockets is a consequence of disturbances, such as thrust misalignments, rocket asymmetry, manufactoring inacuracy, etc.

Application of open-source software for industrial problems of vehicle lift-off gas dynamics

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2017
High-power shock, heat, mechanical and especially acoustic loads present a serious problem as their impact on the rocket and the launch pad can be too strong. Turbulent supersonic jets ejected from the vehicle nozzles are the main source of these loads.

Arrhenius Activation Energy on Viscous and Radiative Heating of Hybridized Chemical Reactive Magnetized‐Casson Nanofluid Flow in Saturated Porous Media With Varied Heat Source/Sink

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study analyzes the influence of Arrhenius activation energy on the chemically reactive, magnetohydrodynamic Casson hybrid nanofluid flow past an exponentially stretching surface embedded in a Darcy–Forchheimer porous medium with a non‐uniform heat source/sink.
