【 摘 要 】

The objective of this thesis is "Optimization of propeller for the existing UAV to produce maximum thrust of 1000N rotating at 8000rpm at higher speed". Diameter of propeller is restricted to 1000mm. Maximum power available is 40KW. The propeller will be made using carbon fiber composite to make it light weight. Propeller is one of the main component in a unmanned aerial vehicle which is responsible to produce thrust. The cross area of propeller edge is an airfoil segment which is ordinarily differing from tip to hub in terms of chord or twist distribution. There are many variables for designing the propeller such as pitch angle, flow angle, chord distribution at the blade span and twist distribution. Blade elements theory will be used for designing the propeller. The blade span is divided into number of cross sectional elements and for each element thrust generated and torque required will be calculated and summed to find total thrust and torque for the propeller. For optimization of blade, these variables will be varied iteratively and optimum solution will be selected.
