Abstract: Aerodynamic configuration design of aircraft has traditionally been a manual process, guided by an experience-driven design philosophy. Although multidisciplinary design optimization (MDO) has advanced rapidly, it fundamentally remains a process of shape optimization based on a predetermined baseline geometry. The aerodynamic performance of this baseline configuration often predetermines and limits the performance gains achievable through subsequent shape optimization. This conventional design paradigm struggles to yield revolutionary aerodynamic configurations. In recent years, with the emergence of the concept of aerodynamic topology design, this methodology has gained significant attention and holds promise for application in the conceptual design of novel aerodynamic configurations for future aircraft. Unconstrained by an initial configuration, aerodynamic topology design has the potential to overcome the limitations inherent in traditional experience-driven aerodynamic design approaches. It provides both a theoretical foundation and methodological reserves for exploring new aerodynamic design paradigms and configuration forms. This paper reviews the historical development of aerodynamic topology design methodologies and summarizes representative case studies where they have been applied to the conceptual design of novel aircraft aerodynamic configurations. It also discusses the key challenges and emerging trends within aerodynamic topology design, outlining critical research questions requiring further investigation.
