Design Analysis and Modeling of a General Aviation Aircraft

In the present study, design analysis is performed to accurately estimate the gross take-off weight, define the externalgeometry, and size the wings and tail of a general aviation aircraft by using the performance parameters associated with apre-defined mission profile and a set of design goals. Three-dimensional layout and projections of the design airplane arecreated using conic lofting-based software. The airplane configuration, the estimated weight, and the real time airplaneequations of motion are then introduced to a simulation environment in Matlab to visualize the take-off, climb and cruisesegments of the mission profile. The simulation has proven the adherence of the design analysis and its results to the designgoals. In addition, finite element software package COMSOL is implemented to perform static stress analysis on the selectedwing configuration when subjected to the generated aerodynamic loads to examine its structural reliability. The finite elementresults have shown that the selected wing configuration is a safe candidate for the present general aviation airplaneimplementation.
