This study investigates the design and modeling process of Distributed Integrated Modular Avionics (IMA) on Electric Vertical Take-Off and Landing (eVTOL) aircraft. It provides an overview of the evolution of IMA technology, with a particular emphasis on its application in Boeing 777, F-22, F-35, Boeing 787, and Airbus A380 models, analyzing the role of this technology in advancing avionics systems. The research highlights the key benefits of IMA in reducing weight, decreasing component count, improving integration efficiency, and enhancing operational flexibility. Additionally, a comparative analysis of IMA architectures adopted by major aerospace manufacturers reveals the differences between centralized cabinet and distributed IMA, as well as their impact on avionics system design.
