DIANA: Data Interactive Analysis and Navigation Application

In the evolving landscape of aircraft design, data visualization is becoming an essential tool to support and enhance the decision-making process. As advanced methodologies such as Multidisciplinary Design Optimization (MDO) and system architecture optimization are adopted, the amount and complexity of design data have grown significantly. While these approaches enable more comprehensive exploration of the design space, they also introduce new challenges: interpreting extensive datasets, identifying interdependencies between parameters, and deriving actionable insights are increasingly difficult. To address this, data visualization is integrated into the design process as a core component that enables engineers to make sense of complex information and drive informed decisions. This paper presents a methodology for developing data visualization tools tailored to the specific demands of aircraft design. It also introduces DIANA, a new application built with these requirements in mind. The paper outlines DIANA’s features and demonstrates its capabilities through a use case involving future aircraft concept studies.
