Impact of System-Level Engineering Approaches on the Airframe Development Cycle Via Integration of KBE with CAD Modeling and PDM

Abstract

A classic airframe development problem is the disconnect between initial layouts/trade studies of structural arrangements and the detail designs that emanate from these layouts. Hence, the process of communicating design change has been time consuming, inefficient, and prone to errors. This paper describes new methods now available that enable the linkage between system-level layouts and the digital master models. Knowledge-Based Engineering (KBE) tools can now be directly linked to preliminary CAD models to refine concepts. Product Data Management (PDM) manes both the KBE and CAD data. As system-level definition and knowledge evolve, changes are automatically propagated down the hierarchy of airframe definition. The result: cycle time reduction and achievement of aggressive performance targets.
