“…Efforts to address these critical points ensure the integration of reliable and mature enough structural solutions for certification and flight operations by developing new design methods. In this work, the development phases of a multi-mode curved Flexible wing flap suitable for large civil aircraft applications are described in detail, with specific reference to the authors' activities within the Clean Sky Initiative [8]. The flaps are modified according to the target shape of the aircraft's flight conditions and are set to improve high lift performance during takeoff and landing and wing aerodynamic efficiency during cruise [9].…”

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.

Low Reynolds number refers to a specific range of values of the dimensionless parameter known as the Reynolds number (Re) in fluid dynamics. The Reynolds number is a critical factor used to characterize and predict fluid flow behaviour around objects or within fluid systems. Low Reynolds numbers (typically Re < 2000), laminar flow prevails, where fluid particles move in smooth, orderly layers with minimal mixing or turbulence. Low Reynolds number aerodynamics is a focal point of interest, especially for micro air vehicles (MAVs), drones, and small-scale aircraft. Understanding the nuanced aerodynamic performance of aerofoils and wings in this regime is pivotal for designing efficient and controllable flight systems, ushe ring in innovations in the field of aviation. The unique characteristics of low Reynolds number flow to advance technology, science, and our understanding of fluid dynamics.
