Abstract:
Over the past two decades, the production of ultra-light drones has increased dramatically. These aircraft are used in applications such as filming, surveying, etc. One of the most important goals is to fly them for a long time. From time immemorial, a lot of work has been done to get such birds to fly, but nothing has ever been done on their engines and propellers, and they have always been considered ideal models (in other words, their efficiency is a bit ideal). In this dissertation, the main purpose is to study some of these sets and to obtain the flight time of a particular drone. First, a low-velocity wind tunnel was built to examine these complexes, then we tested these complexes inside this wind tunnel and extracted the mathematical model between their power consumption, velocity and thrust, and finally considered these collections for a specific UAV. And we simulate how long this particular drone will fly by each set. We also get returns for each set of motors and locusts. Finally, it is said which engine and propeller set is the best set for the above drone and the drone has the longest flight time
