e-AIRS: Aerospace integrated research systems

While developing information technology and improving engineering environment, modern aerospace technology requires even larger scale computing and data management. However, the technology faces difficulty to use isolated resources. Therefore, needs arise to construct network based and integrated design and analysis system. In order to provide a uniform aerospace development infrastructure, three perspectives are required (i.e., integration and management of aerospace resources located in multiple organizations and areas; facilitating human collaboration in aerospace fields; and remote access and operation of aerospace facilities and instruments). National e-Science project has been developing by the Ministry of Science and Technology and the Ministry of Information and Communication in Korea. Many worldwide organizations and institutes have conducted research on the development of e-Science paradigm. USA NASA has focused on information power grid (IPG), which is designed for environment of real time design, manufacturing, and maintenance of aircraft in grid base. In the United Kingdom, grid based researches is classified into mainly two systems: grid based aircraft multi-discipline optimal design system (GEODISE) and grid based real-time aircraft operation and maintenance system (DAME). In Japan, grid based supersonic aircraft design focused on a sort of integrated aerospace, full cell, materials design, and regional environment. The national e-Science of Korea is commonly contributing to construct of aerospace e-Science (called e-AIRS project). In e-AIRS project, design/ analysis network for aerospace vehicle based on national grid system has been constructed. It also provides collaborative use of aerospace test facilities and equipments dispersed in organizations, institute, industry, and academia. In addition, this project also aims to construct infrastructure for collaborative use of information and database for aerospace vehicle design/analysis. This presentat- - ion will address an overview of e-AIRS research activities and a concept demonstration about e-Science portal interface, integrated mesh generation and CFD computation services, and parametric study service for high throughput computing. The parametric study service, which is working on Grid environment, has flexibility to be extended to design optimization. A remote request service for wind tunnel experiments and a collaboration service consisting of video/audio conferences are also introduced.
