Abstract : The conventional process of a new aircraft design and development is based on sequential analysis and test cycles. Using an integrated CAE-CAD-CAM technique it is possible to increase the depth of the different configurations analysis, to reduce the cycle time and even the number of cycles required, and to achieve optimised design, thereby improving the product, shortening the overall development time, and reducing development costs. The capability of CAD systems to manipulate 3-D geometric models utilizing data base of standard components, allows the integrated development of aerodynamic and structural configurations, and of systems layout. A computerised mock-up developed at CAD allows to converge on a unique mathematical model different disciplines, making easier integrations between structures and equipments. The CAD total data base integrated with analysis and manufacturing permits direct data transfer from engineering to manufacturing (CAM) and in addition makes faster and cheaper the embodiment of modifications during the development phase.
