Propulsion Selection Method Using Motor Thrust Table for Optimum Flight in Multirotor Aircraft

摘要

One of the problems when designing an aircraft is flight time estimation. When we design the aircraft, in general, calculating the maximum takeoff weight becomes the priority. The longer flight time required by the aircraft, the more batteries should be added. More batteries mean the payload capacity of the aircraft is decreased. On the other hand, adding more weight will increase the requirement of using more powerful motors. We need to take into our account, that using powerful motors should be calculated carefully because the current consumption is also increased. This problem is circling in the same situation, without any real solution to overcome the problem. As unmanned aircraft has become a critical part of human life for example in surveillance, agricultural, and medicine delivery mission, obtaining the optimum and efficient flight time is vital. In this research, we propose a novel approach of maximum takeoff weight calculation that is needed when designing the aircraft by looking at the complete map of motor specifications. The goal of this paper is to help any aircraft user from hobbyist to professional to determine whether their aircraft design is feasible.
