This study highlights the practical utility of SysML v2’s kernel language, a formal, text based foundation for consistent, cross tool model definitions, in Model Based Systems Engineering (MBSE), using Air Traffic Management (ATM) as an illustrative example. SysIDE, an open source textual editor, enables rapid model creation with the kernel’s concise syntax, allowing users to define system components and behaviors (e.g., ATM radar or flight path interactions) with real time validation. SysON, a web based graphical tool, complements this by facilitating collaborative visualization of system architectures. Using ATM as an example case, we can showcase how the kernel language enhances design efficiency, and reduces iteration cycles compared to SysML v1. This work underscores SysIDE and SysON’s effectiveness in leveraging SysML v2’s kernel for MBSE, with broad applicability across complex systems engineering domains.

Efforts to achieve more sustainable commercial aviation have led to substantial advancements in the operational efficiency of turbofan engines. The majority of these are associated with improvements in engine aerodynamics, propellants, and turbomachinery design such as higher bypass ratios, serrated fan blades, additional high-pressure compression stages, or adoption of less emission fuels. Such advancements enable much higher temperature and pressure inlet conditions into the combustion chamber which can put thermal load fatigue by exceeding the thermal limits of nickel-based superalloys coated with Yttria-Stabilized Zirconia. As a result, newer engines are shifting towards using silicon carbide based ceramic matrix composites with environmental barrier coatings which offer higher thermal resistance. Therefore, this study will conduct a literature review between these two thermal barrier coatings for commercial aviation turbofan engines, reviewing primarily the heat transfer capabilities of these coatings. Through analyzing the heat transfer properties, advantages and limitations of each thermal barrier setup is expected to be reviewed.
