Project Summary

The project “Design and Fabrication of Ornithopter”, as the name demonstrates, is about the design, simulation and fabrication of flapping wing bird-sized aircraft also known as Ornithopter. The purpose of constructing this flapping wing aerial vehicle is that is serves several purposes such as surveillance in constrained area and bird repellant. The project consist of several steps which includes, design of wing for the ornithopter, gear mechanism design, preparation of 3d- CAD model, simulation, fabrication and flight testing. This bird size ornithopter is based on Kestrel bird and also the Sean Kinkade model. The wing design has been based on Modified Strip Theory, in addition to this, aerodynamic forces has been calculated. After completing the design and obtaining parameters, it has been modelled using CAD software, CATIA and SOLIDWORKS. The simulation has been done in order to support the design and it has been verified through graphs using other software such as MAPLE and ADAMS. The component required for the fabrication has been listed and ordered. The next and final step will be fabrication of the design and flight testing of the model.

Project Objectives

The main objective is to design a flapping wing unmanned aerial vehicle based on American kestrel bird and different models. The designed ornithopter will be capable of a stable flight with a gliding controller implemented in order to avoid crashing.

Project Implementation Method

After studying literature thoroughly, there has been different techniques implemented, for design of wing, modified strip theory has been used. After that the main frame and total body length of the design has been calculated by referring the American kestrel bird. The 3-D CAD model of the design has been done. This model was simulated using SOLIDWORKS, after that the max flapping angle has been found out through motion analysis. Before modelling, all the gear ratios has also been calculated. Now the only steps that remain are fabricating this model and flight testing which will give us a proper working ornithopter having a stable flight.

Benefits of the Project

Flapping wing due to their appearance like bird which are natural predators and highly maneuverable have certain unique applications

• Used for surveillance in inaccessible areas (Military purpose)
• Used for security purposes for firms or factories
• Air reconnaissance
• Bird repellent at runways

Technical Details of Final Deliverable

The final deliverable of the project is an Ornithopter having a stable flight which has a gliding controller implemented so that it does not crash into ground.

• The flapping angle of the UAV will be from -26 to 26 degree.
• The wing mechanism implemented will be articulated.
• The ornithopter will be having endurance of 5 minutes and the height of 30 ft.
• The total weight of flapping wing UAV will be 0.4715 kg.
