Abstract
Nowadays, a UAV is an important vehicle. Many countries already have their own UAV, even Singapore. Malaysia already has RazakSAT, so it is possible to have a UAV developed by Malaysian. The use of the UAV is everywhere because it gives a lot of benefit which include cost reduction, increment in safety level and simplification of hard tasks. The main objective of this thesis is to generate a 3D model of Predator and compare it with the actual Predator that exists nowadays. Seven pivot points was suggested by Anderson[10] for conceptual design which are mission requirements, first estimation of the airplane weight, critical performance parameters, layout configuration, better weight estimation, performance analysis and optimization. Each single result was compared to the Predator’s performance and was discussed why there is a difference between those two UAV’s parameters. This UAV was designed to operate in Malaysia so it has different parameters compared to Predator developed by USAF. The project outcome is a 3D model of the Predator and it is a bit different from the actual Predator but perhaps the layout configuration will changes in preliminary and detail design. The result obtained is acceptable and it is possible for Malaysian to have own UAV. It will be used in preliminary design which aerodynamic, structural and control system analysis take place. Finally, the design process will enter detail design also called nuts and bolts phase which size, numbers and location of fasteners will be determined before the fabrication takes place.
