Traditional aircraft face limitations in dynamically adjusting wing lengths in constrained settings to reap aerodynamic benefits and spatial efficiencies. Moreover, in-flight self-repairs for wing damages induced by external circumstances are unfeasible. Addressing these issues, this paper introduces two distinct mechanisms: a balloon-assisted inflatable wing at the end of the wings and another based on the multistable inflatable origami structures. The former offers dynamic wing length adjustments in space-restricted urban environments, while the latter, with its multistable inflatable origami design, allows the detachment of a damaged wing and its replacement with an inflated origami-style wing. To realize these two mechanisms, directing fluid through the main wing is imperative. The paper proposes the use of an S duct as a solution and presents the design of both the S duct and a UAV platform. The feasibility of these mechanisms has been substantiated through mathematical equations for aircraft design and Computational Fluid Dynamics (CFD) analysis using Ansys.
