Application-database interface design for the real time simulator system

In this paper, the design, development and evaluation of application-database interface (ADI) are presented. The main purpose of this study is that improving the simulation quality to get more realistic response of target system. The requirements and operation logics are obtained from real aircraft flight test database. And, stability & control, flight control, and aerodynamic engineering requirements are considered. Because original database structure was designed for aircraft characteristics realization in engineers' usage side, ADI needs to convert it to the new suitable structure for computational methods and provides mathematical operation algorithms. The expandability is considered to adapt ADI to other modeling target. The designed and developed major functions are flexible memory structure, efficient arithmetic database language, and the high speed interpolation / extrapolation algorithm. To evaluate the reliability and performance, ADI inserted to existing real time simulation software, and is tested for operation speed and accuracy of returned data.
