Design and analysis of a tethered-glider for generating electrical-renewable energy using the pumping cycle method

Abstract

The issue of energy generation from wind is considered one of the main ways to develop renewed energy in some areas worldwide. The important point in generating energy from wind is the permanent wind availability, which is called the existence of effective wind. According to studies, there is no effective wind at ground level in many areas of the world, while this wind is available at altitude. The Accessibility of wind in altitude has led to the development of various technologies in energy production from airborne systems. In this research, airborne wind energy systems technologies have been investigated, and a tethered-glider was designed and analyzed using analytical methods for energy generation at a 200-meter altitude. The main factor in designing a glider is the optimal ratio of lift to drag coefficient; For calculating lift to drag coefficient, the vortex lattice method (VLC) is used in this paper. The results illustrate that a glider with a wingspan of 5.2 meters can produce a maximum of 10 kilowatts of energy over one cycle. Increasing this ratio can increase energy production efficiency.
