KNOWLEDGE-BASED INTEGRATED AIRCRAFT WINDSHIELD OPTIMIZATION

摘要

Innovation is the key to new technology. Atthe "Division of Fluid and Mechatronic Systems,Linköping University", a framework foraircraft conceptual design is continuously devel-oped. RAPID (Robust Aircraft Parametric Inter-active Design) and Tango are knowledge-basedaircraft conceptual design tools implemented inCATIA® and Matlab® respectively. The workpresented in this paper is a part of RAPID, ex-plores the method, and proposes a framework forfuselage optimization with a parametric, reusableand automated windshield with a focus on the pi-lot visibility for conceptual design. The geome-try is initially propagated from CAD (CATIA®)to CFD (Ansys®) using CADNexus. Initial opti-mization implemented on a 2D geometry to findan appropriate angle for the struct. An overall op-timization to minimize the drag and maximize theload taken by windshield struts depending on pi-lot’s eye position, floor height and cockpit lengthperformed. Methodology to automatically meshusing Fine™/Open with OpenLabs and Ansys® , asthe number of surfaces increases or decrease through-out the design automation is also proposed and usedduring the optimization.
