Morphing Wing Concept for Small UAV

Abstract

The biological flight involves the movement of a wing (lift surface) in viscous medium and it generates lift and resistance for going forward through friction compared to Reynolds number. The morphing concept is generally based on optimizing the aerodynamic form during the mission so it can execute a maneuver flight. This article desires a short passage through the mathematical aspect in 2D of the morphing profile concept.

ANALYSIS OF UAVs FLIGHT CHARACTERISTICS

“…13) indicate a reduced dependence on the lateral stability of the geometric configurations influenced by the use of the four analyzed profiles, the net differences increase with the increase in the incidence of flight. Starting from the 2D profile approach, the morphing concept can be used to construct 3D lifting surfaces, especially for maneuvering by adaptive control [10,11,12], both using morphing profiles (FIG. 15) and 3D wing torsion (FIG.…”

Unmanned Aerial Vehicle Future Development Trends

“…Rapid and controlled modeling of the aperture and wing geometry can also be used to actively control some undesirable phenomena such as airplane detachments at low attack angles, or the occurrence of wing-induced aero-elastic loads, see Figure 5. Changing the shape and profile of a wing for different types of mission has been the subject of extensive studies reported in the literature [11,12,13,14].…”

Numerical Analysis of Variable Morphing Wing for Improved Aerodynamic Performance of a Predator MQ-1B

“…Remotely piloted aircraft first appeared during world war I, but the early efforts were stymied by the primitive guidance technology available. NASA (Kudva, J. et al, 1997), DARPA (Kudva, 2004)and also most of researchers (Abdulrahim et al, 2005;Bourdin, Gatto and Friswell, 2006;Gomez and Garcia, 2011;Prisacariu, Boscoianu and Cîrciu, 2013;Kaygan and Gatto, 2016;Prisacariu, Boşcoianu and Cîrciu, 2017) have been conducted performance studies regarding unpiloted morphing aerial vehicles. (Abdulrahim et al, 2005) designed twist morphing wings and flight tests demonstrate the actuation causes sufficient deformation of the wing to result in significant control authority.…”
