Conceptual and Preliminary Level Modeling of Wings Using the Adaptive Modeling Language

Authors: Geetha Bharatram; Jeffrey V. Zweber; WRIGHT LAB WRIGHT-PATTERSON AFB OH FLIGHT DYNAMICS DIRECTORATE
Abstract:
This memorandum demonstrates a methodology for an automated design process. The design process was developed in the Adaptive Modeling Language (AML). This effort concentrates on developing a system for linking conceptual level wing geometric parameters to a preliminary level finite element model. This environment allows for rapid changes in the geometric parameters of the wing planform (e.g., wing sweep, span, chord length, etc.) as well as the capability for updating internal substructure (i.e., number and placement of ribs, spars and stiffeners) in an integrated environment. In this effort, a fully associative geometric design model (developed in AML) is coupled with an aerospace structural optimization code, ASTROS.
