    Abstract

    As part of conceptual design effort for a civil air-vehicle many sizing decisions should be taken. These decisions should be taken desnite existence of chicken-or-the-egg dilemmas. i.e. deciding the aircraft configuration sizing parameters without knowing its appearance and performance, and deciding its appearance and performance without bowing its sizing parameters. The paper gives a review of a multidisciplinary framework which uses modeFrontier environment. This framework consists of several software modules which were integrated into a single synergic tool. In the current scope this design tool is used to decide the aircraft wing loading while taking info account various performance constraints. The importance of the multidisciplinary analysis tool is demonstrated and its ability to handle large number of cross-influences is discussed. The existence of several disciplines integrated into a single multidisciplinary tool may introduce some difficulties, mainly if engineering intuition is involved.
