The ever increasing complexity of aerospace design has seen the emergence of Aerospace Design Automation, the study of design of aircraft/aerospace vehicle design systems. Our previous publications have dealt with its foundation, the Aerospace Design Representation Programming Interface (AERO-DRPI).To model the design, process and status data the AERO-DRPI uses data schemas appropriate for a tool and data combination. A data schema enables the definition of semantics and syntax of design, status, and process data.For generic design management, a data schema is required on which all the generic operations are possible. It should also meet all the requirements for generic design management. The generic design management schema should be extendible with minimum data redundancy.A specific design management data schema uses the generic design management schema as its foundation. For a specific design sub-discipline there are specific schemas. These are built in collaboration with sub-discipline experts.In this paper, generic schema for aircraft design, and specific schema for aircraft conceptual design are proposed. The process of synthesizing these schemas is outlined. It is shown how these schemas can be used by the AERO-DRPI.
