Abstract: The development of the future aviation industry needs to solve the key problems of multidisciplinary integrated design and provide a powerful design method and tools for the design of new high-performance aircraft. This paper presents an automated digitalized integrated platform for aerodynamics synthetic design and assessment (DIPasda) for complex shape. Our goal is to present a new general-purpose, robust, and efficient optimization platform which is aimed at real-life constrained designs where the conventional design approaches are complicated and time-consuming. The DIPasda system consists of a collection of functional modules for performance design and optimization studies by numerical optimization schemes, geometry parameterization techniques, surrogate models, high-fidelity computational analysis tools for different disciplines and so on. By introducing the system architecture of the platform in detail, the main functional modules, adjoint optimization, and multi-objective optimization process, the flexibility of the system architecture design and the completeness of the functional modules are demonstrated. At last, optimization tests are presented to show the system's design optimization capability.
