Design and Analysis of Unmanned Aerial Vehicles Wing

wing to the material differences in the natural and engineered systems, the design of a biological-inspired aircraft possesses considerable challenges to the aircraft designer. The birds employ a structure of hollow bones, flexible joints and muscles, and feathers to morph their wings to suit the desired flight condition. While the aircrafts use the rigid joints and structures to sustain the aerodynamic loading. With this underlying difference between the two systems and the aim of this research work being to understand the aerodynamic benefits of morphing wings, it is not desired to exactly emulate the bird wing kinematics. Rather, the objective is to devise a mechanism to emulate the bird wing shapes and aspect ratios for quasi-steady aerodynamic analysis using computational and experimental setups. In this project, we propose mechanisms to continuously morph a wing from a lower aspect ratio to a higher and to further extremities of a gull and an inverted-gull configuration. The mechanism comprises of a linear actuator for the extension of the wing and the servo motors to obtain the gull and inverted gull configurations. The design process includes conceptual sketch of wing structure followed by detailed design with suitable constraints and design of 3D model in SOLIDWORKS. It is then imported to ANSYS for computing impact of loads occurring due to combined operation of servo motors and actuators.
