Parametric Design of Aircraft Wing with Curved Leading Edge

Abstract

In order to ease modelling procedures, eliminate repetitive effort and save time, modern CAD tools offer the ability to automate tasks via a programming language. Moreover, when the design is an iterative process, the automation permits updating the design variables to generate a new model at each iteration. Based on UG/OPEN GRIP functionalities, this paper aims at developing a parametric model of a curved leading edge aircraft wing. The model is built by executing a GRIP program in which wing parameter values can be assigned via a dialog box.
