Abstract

Tail-sitter vehicle take-off and landing unmanned aerial vehicle (Tail-sitter VTOL UAV) is a type of aircraft that is receiving a lot of attention and being widely studied today. But a design through initial assumptions and weight estimates will have to spend more time designing and testing because the prototype obtained from the design in each cycle will deviate from the reality. As a result, the designed prototype is not the most efficient prototype (judged by the flight endurance). Studies are aimed to increase its capabilities to fulfill various mission objectives. This study is aimed to create a preliminary tail-sitter design algorithm with optimization to improve designing capabilities using collected data from resources available in the market to make a database and decreasing design time by using optimization in choosing propeller process. Finding the best endurance UAV for every 3 cases of design condition. By using Hooke-Jeeves pattern search optimization method, a result show an algorithm can select the right equipment for a require mission and designing time are decrease up to 55% from the whole time that used to compare every possible solution.
