Study on the Evolution of Drone Engine and the Future of Drone Propulsion

Shahrzad Mozafari Ghazafi

Abstract


UAVs are remotely piloted birds which are one of the new and strategic equipment of our time. Although in the past the main use of drones has been in the military industry, in recent years the use of drones in the civilian industry has been significantly welcomed. Scientists have always tried to increase the capability of drones. To this goal, they have tried to upgrade it by optimizing the various components of the drones. One of the main components of a drone is its engine, and researchers have done extensive research to increase its power while reducing its weight, volume, and fuel consumption. The aim of present research is to study on upgrade of drone propulsion. For this purpose, first the development trend of propulsion in the past and present years was analyzed and then the future of UAV propulsion was estimated. The results show that in the coming years we will see a significant upgrade in drones. In summary, fuel consumption will be decreased by 30%-20and the weight of the propulsion system by 20%-15. In addition, the thrust to weight ratio will growth by20- 30%. According to long-term plans, carbon dioxide emissions and engine noise will be reduced by 50% and 10 dB, respectively.


Keywords
