Design and analysis performance of fixed wing VTOL UAV

Abstract

Mainly there is two type of UAV, multirotor and fixed wing and each of this type have their own advantages. Combination of both type UAV can enhance the capability of UAV. The problem to this idea are the effect of modification on thrust performance as the wing loading increase. This study presents a conceptual design of fixed wing vertical take-off and landing (VTOL) UAV based on ready-to-fly (RTF) fixed wing UAV. This mean the UAV has ability not only to take-off, landing or hover as multirotor aircraft but also able to cruise similar to the fixed wing UAV. This paper discussed on the design modification of fixed wing UAV and thrust performance for take-off, hover and landing during multirotor mode. Mass balance analysis is performed to ensure that addition and placement of motors and other equipment are in such way the center of gravity does not change from the original UAV to retain its original stability. For the thrust performance, thrust required for multirotor mode is compared with the thrust available produce by the motors obtained by doing the thrust test. Based on the analysis, the capability of UAV to fulfil the mission requirement is determined.
