Design and Analysis of Flexible Wing

Abstract

Modern transport aircrafts are introducing high lift devices to overcome the contradiction between economic considerations and low flight speed lift requirements. The flaps are known as high lifting devices. This paper contains an exploration of the analysis of aerodynamics characteristics and other characteristics properties of flaps with the help of the CAD modelling software’s such as CATIA and SOLIDWORK. The modelled geometry is analyzed in the CFD software ANSYS. Flexible wing has great potential to improve overall aircraft performance, just as natural aircraft do by adjusting the shape or dynamically optimizing for various flight conditions, and there are many untapped opportunities beyond the current proof-of-concept demonstration. This review discusses the most important examples of the application of the concept of deformation to 2D and 3D airfoil models. The methods and tools commonly used to design and analyze these concepts are discussed, ranging from structural analysis to aerodynamic analysis, from control aspects to optimization. Throughout the review, it became clear that the use of the concept of Flexible for everyday use in aircraft is still rare, and some reasons were given which hindered its mainstreaming for industrial use. Finally, promising concepts for future use are identified, these are also analyzed in the CFD software.
