DEVELOPMENT OF AUTO-GENERATING AERODYNAMIC LOADS FOR WING-BOX FINITE ELEMENT MODEL BASED ON SCHRENK METHOD
Abstract: This paper describes
the development of computer application for computing the wing lift
distribution and auto-locating each sectional lift force to the appropriatenodes
of wing-box finite element model (FEM). In Catia-V5 environment, Visual Basic.Net
is intensively utilized to access several Catia’s Component Object Models
(COMs) by implementing several user interfaces for collecting flight data from
user and for linking to the wing-box finite element model that already created
in the previous work. Thedistribution of lift force is governed by Schrenk
method, where the distribution is multiplied by limit load factor and safety
factors in order to conform to the airworthinessrequirement. The lift force is
computed for each rib-space area and located on a point of quarter chord called
a Handler. Correspondingly each upper wing surface of rib-spacecalled Agent
conducts as media to transform each lift force from a handler into their associated
nodes of FEM. To demonstrate this work, a hypothetical N250 wing box structures
is utilized for a case study. The result of this work is very useful to be
utilized for wing design involving aerodynamic and structure analysis.
