2023年1月21日 · The maximum distance between the two lines is called the camber, which is a measure of the curvature of the airfoil (high camber means high curvature). The maximum distance between the upper and lower surfaces is called the thickness .
Realization of an optimized wing camber by using formvariable …
2001年10月1日 · Since both lower and upper skins are flexed by active ribs, the camber variation is achieved with a smooth contour and without any additional gaps. This approach for varying the wing's camber is designed to be used for replacement and enhancement of a given flap system.
Design and validation of a variable camber wing structure
2024年2月1日 · Variable camber wing technology is one of the important development trends of green aviation at present. Through smooth, seamless, continuous and adaptive change of wing camber, the aerodynamic performance is improved in achieving increase in lift and reduction in resistance and noise.
Status and Challenges on Design and Implementation of Camber …
2021年12月14日 · The wing’s ribs were designed to exploit the material anisotropy and strength of the composite material, achieved by additively manufacturing ribs with CFRP and polyamide-12. The push-pull movements of the actuator rod deflect the trailing edge, and individually controlled actuators are distributed along the span to change lift distribution ...
Unleashing the Potential of Morphing Wings: A Novel Cost ... - MDPI
2023年6月5日 · A novel morphing concept developed for the Stingray UAV, Rear Spar Articulated Wing Camber (RSAWC), employs a fishbone-like morphing wing rib design with rear spar articulation in a cost-effective manner. The design process and flight tests of the RSAWC are presented and directly compared with a conventional wing.
Analysis of Bio-inspired Fishbone Based Corrugated Rib for …
2023年1月10日 · In the present article, a bio-inspired Fish Bone Active Camber (FishBAC) corrugated rib design concept with and without a spine for an Unmanned Aerial Vehicle (UAV) is proposed. The wing model is composed of multiple corrugated ribs and a splitted spar for connecting each rib.
Multidisciplinary Design and Optimization of Variable Camber Wing …
2023年3月28日 · Balaji designed a multi-segment variable camber fixed wing for unmanned aerial vehicles, utilizing four rib segments with pneumatic actuators, and found that a basic linkage framework inserted inside the wing can achieve a camber change .
In this paper, an innovative double rib sheet structure is proposed, which can replace the traditional rigid hinge joint with the surface contact. On the one hand, the variable camber wing structural design not only can improve the capacity to sustain more load but also will not increase the overall weight of the wing.
Complete morphing wing design using flexible-rib system
2015年9月28日 · In this work, we present a realistic morphing wing design for small UVAs. The focus of this study is to develop a novel morphing wing system that adopts continuous camber adjustment of the airfoil between two designated stages. The morphing function is achieved using a set of flexible ribs along the wing span.
