Design, Fabrication and Modification of Small VTOL UAVAkshat Srivastava
The target of the project is to design a vertical takeoff Unmanned Aerial Vehicle. The design configuration selected is a four rotor design. Preliminary calculations regarding the material selection was performed. Fabrication was carried out beginning with the frame assembly, followed by the integration of the electronic components. At the same time, the various analyses were performed in order to predict the real time performance of the Quad rotor design. Beginning with structural analysis on Catia, the structural deformation of the frame was studied; the analysis was further refined on the Ansys Workbench. Ansys workbench is an easy to use interactive interface. Following the structural analysis was the Modal Analysis that was performed to evaluate the resonant frequencies or the modes of the vibrations of the frame. Then flow simulation was performed again on the Ansys workbench using the fluent solver and CFX post processing software. This analysis was performed to study the flow behaviour around the quad rotor design. Various plots of the flow parameters were obtained and analyzed. After the assembly of all the individual components was performed, flight testing was performed. The testing was performed for a number of times, various adjustments were implemented, recalibrated several electronic components. The software was reconfigured several times to obtain the desired response from the board. The testing has resulted in minor improvements in the design.
