Supersonic passenger aircraft have regained attention in recent years as advances in aerodynamics, materials, and digital engineering continue to expand the possibilities for high-speed air travel. At the same time, these aircraft introduce engineering challenges that are often more demanding than those encountered in conventional aviation. Fuel systems, in particular, must operate safely under elevated temperatures, complex subsystem interactions, and demanding operating conditions. Addressing potential hazards early in the design process is therefore an important aspect of aircraft development. A recent study published in Aerospace, titled “Integrating Computer-Aided Design and Model-Based Systems Engineering for Early Zonal Hazard Analysis: Application to a Supersonic Aircraft Fuel System”, presents a framework that combines Computer-Aided Design (CAD) and Model-Based Systems Engineering (MBSE) to support hazard analysis during the conceptual design stage of a supersonic aircraft. Figure 1. Integrating CAD and MBSE for Early Zonal Hazard Analysis. Produced by MDPI Academic Video Service (Source: https://encyclopedia.pub/video/1819). 1. Safety Challenges in Supersonic Aircraft Design Safety assessment is a fundamental component of aircraft development. One commonly used approach is Zonal Safety Analysis (ZSA), which examines the interactions between systems and components located within specific areas of an aircraft. Traditionally, these assessments rely heavily on documentation, engineering reviews, and expert judgement. As aircraft systems become increasingly interconnected, however, potential hazards often arise not only from individual components but also from their interactions with surrounding structures and neighboring systems. In supersonic aircraft, fuel systems may be affected by thermal loads, environmental control systems, structural elements, and propulsion-related components. Detecting these interactions late in development can result in costly redesigns and extended development schedules. For this reason, there is growing interest in approaches that enable safety considerations to be incorporated earlier in the design process. 2. Linking System Architecture and Aircraft Geometry The framework proposed in this study combines two complementary engineering tools. CAD models provide detailed information about the physical arrangement of aircraft structures and subsystems, allowing engineers to evaluate component placement, spatial relationships, and potential thermal or structural concerns. MBSE, by contrast, focuses on system functionality and interactions. It provides a structured representation of how different subsystems communicate, exchange resources, and respond to failures. By integrating these two approaches, the framework links aircraft geometry with system architecture, enabling hazard analysis to be performed while the aircraft configuration is still evolving. Information from CAD models can inform system-level assessments, while the results of safety analyses can guide subsequent design modifications. This iterative process supports the refinement of both subsystem layouts and system architecture throughout conceptual development. 3. The SA-24 Phoenix Fuel System To demonstrate the framework, the researchers applied it to the fuel system of the conceptual supersonic aircraft SA-24 Phoenix. The study examined several hazards associated with fuel-system operation in a high-speed aircraft environment, including fuel vaporization caused by elevated temperatures, fuel tank over-pressurization, leakage scenarios, and structural fatigue resulting from thermal stresses. The analysis incorporated established safety assessment methods, including Functional Hazard Analysis (FHA), Failure Modes and Effects Analysis (FMEA), and Fault Tree Analysis (FTA), while also considering relevant certification requirements derived from EASA CS-25 standards. Using the integrated CAD–MBSE framework, the researchers were able to evaluate both the physical arrangement of system components and the functional relationships between subsystems, providing a more comprehensive view of potential risks during early design stages. 4. Hazard Pathways and Mitigation Measures The analysis identified several subsystem interactions that could contribute to safety risks. For example, heat generated by environmental control system ducting could influence fuel temperatures, while the proximity of fuel-system components to other aircraft systems created additional considerations for hazard management. The integrated framework also allowed potential mitigation measures to be evaluated during conceptual design. These included thermal insulation, thermal shielding, increased subsystem separation, redundant venting arrangements, and structural fire barriers. Because hazard analysis and design evaluation were conducted within a connected modeling environment, potential design changes could be assessed and incorporated earlier than would typically be possible using conventional document-based approaches. According to the study, the proposed framework resulted in an estimated reduction of up to 40% in Risk Priority Number (RPN) values for key thermal hazard pathways. The authors also report an approximately 25% reduction in conceptual design iteration time compared with traditional approaches. 5. Implications for Future Aircraft Programs Although demonstrated using a supersonic fuel system, the framework has potential applications beyond this specific case study. Many modern aircraft contain highly integrated subsystems whose interactions can be difficult to evaluate using conventional methods alone. The study reflects a broader shift toward digital engineering practices within aerospace development. By connecting geometric models, system architecture, and safety assessment activities, integrated digital frameworks can improve traceability between design decisions and safety requirements while supporting more informed engineering decisions throughout development. 6. Conclusion The study demonstrates how CAD and MBSE can be integrated to support zonal hazard analysis during the earliest stages of aircraft design. Using the SA-24 Phoenix fuel system as a case study, the authors show how linking physical and functional models can help identify potential hazards, evaluate mitigation strategies, and support safety-informed design decisions before detailed development begins. As aircraft systems continue to grow in complexity, approaches that enable earlier assessment of subsystem interactions may become increasingly valuable. While further refinement and validation are still needed, the framework presented in this work highlights the potential of digital engineering tools to support more efficient development processes and earlier identification of safety issues in future aircraft programs.

West African cuisine is among the world’s most complex and historically significant culinary traditions, shaped by diverse ecosystems, centuries of trans-regional trade, and the cultural heritage of more than three hundred distinct ethnic groups spanning the Atlantic coast and the Sahel. West African cuisine has undergone a significant cultural and culinary transformation in the American food landscape, moving from relative obscurity to mainstream visibility. This entry examines the rise of West African cuisine in the United States, with particular attention to jollof as a cultural symbol of identity, diaspora, and culinary diplomacy. Drawing on academic scholarship, food journalism, and primary cultural sources, the entry traces the historical roots of West African foodways through the transatlantic slave trade and their enduring influence on American culinary traditions. It further explores how contemporary chefs, restaurateurs, and food writers of West African descent, including Eric Adjepong, Pierre Thiam, and Kwame Onwuachi, have elevated the cuisine within American fine dining and popular culture. The entry also addresses the role of social media, particularly the viral “Jollof Wars,” in amplifying West African culinary culture globally, culminating in UNESCO’s recognition of Senegalese jollof rice as an element of intangible cultural heritage. Questions of structural barriers, authenticity, and representation are critically examined. The entry argues that while West African cuisine is experiencing unprecedented visibility in America, its mainstream acceptance remains mediated by cultural filters that risk diluting its complexity and richness. Ultimately, this entry positions West African cuisine not merely as a culinary trend but as a living expression of diasporic identity, cultural resilience, and global influence.

The terms democracy and the pedagogy of the possible name an approach imagining schools as sites where more just, inclusive and participatory collective life can be practised, particularly in early childhood. The entry brings three traditions into dialogue. (a) Critical pedagogy, particularly in its post-structuralist, Foucauldian, and post-Marxist readings, engages with Rancièrian critiques of pedagogical mastery and offers a vocabulary for examining how power, knowledge, subjectivity, and hegemony are produced and contested within educational life. (b) Freinet pedagogy, extended through Fernand Oury’s Institutional Pedagogy, contributes a politically grounded, practice-first repertoire of cooperative techniques, classroom institutions, and democratic forms of organisation. (c) Educational commons approaches frame knowledge, space, time, and pedagogical relations as shared goods, collectively produced, cared for, and democratically governed by a community of teachers, children, and families. In this perspective, the child is approached as a commoner and agent in the here and now. The educator, in turn, is understood as a fellow commoner and reflexive practitioner, capable of acting beyond the logics of both the state and the market. Together, they co-shape the everyday life of education. Eight shared dimensions, namely the relational, the political, praxis, agency, anti-enclosure, prefiguration, community, and the schoolized mind, traverse all three traditions, with care as their transversal thread. The framework is conceived as a hospitable theoretical and practical space, not as a self-contained doctrine. It is heuristic in orientation, bringing these traditions into conversation because each contributes a complementary layer to democratic educational life.
