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.

Experimental Flow Investigation of a Truncated Ideal Contour Nozzle [PDF]

, 2006
Various tests showed a significant side load peak for low nozzle pressure ratios during engine start-up and shut down phase. DLR Lampoldshausen carried out tests to examine the flow field in a truncated ideal contour nozzle for low NPR.

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.

Transition Metal Carbide‐Based Catalysis for Thermocatalytic Conversion Processes: Properties, Synthesis, Applications, and Future Outlook

ChemNanoMat, EarlyView.
Transition metal carbides (TMCs) have electronic structure similar to that of platinum group metals, making them attractive for thermocatalysis applications. This review explores several essential aspects, discussing physical and chemical properties of TMCs, synthesis methods, and their utilization in thermocatalytic processes, including generation of ...
