“…Wind turbines are characterized by their rated power, which is the maximum power a particular device can extract from the prevailing wind. Several power curves have been reported in the literature for existing airborne wind energy prototypes and planned devices (Faggiani and Schmehl 2018;Echeverri et al 2020;Eijkelhof et al 2020;Vimalakanthan et al 2018); however, these power curves are highly specific to their respective designs and do not reach the 5-MW power rating that is expected to be typical of an average traditional wind power plant installed in 2030 (NREL 2020).…”

This section briefly describes the way in which this report addresses the congressional request regarding focus and scope, the consideration of AWE in relation to traditional wind energy, and the approach taken to develop the report. Addressing the Congressional Request: Focus and ScopeThis report describes technical analyses of various aspects of AWE provided to the U.S. Department of Energy (DOE) Wind Energy Technologies Office to underpin DOE's response to the congressional request for a report on AWE in the Energy Act of 2020, which states:-Not later than 180 days after the date of the enactment of this Act, the Secretary shall submit to the Committee on Science, Space, and Technology of the House of Representatives and the Committee on Energy and Natural Resources of the Senate a report on the potential for, and technical viability of, airborne wind energy systems to provide a significant source of energy in the United States.

Airborne wind energy (AWE) is an emerging technology for the conversion of wind energy into electricity by flying crosswind patterns with a tethered aircraft. Having a proper understanding of the unsteady interaction of the air with the highly dynamic system during operation is key to developing viable AWE systems. High fidelity simulation tools are needed to correctly predict these interactions, which will provide insights into the design and operation of advanced and efficient AWE systems. The research goal of this contribution is to predict the time-varying aerodynamic forces acting on a reference system, which will be achieved using high-fidelity modelling. This work contains a feasibility study that uses the Chimera overset technique to simulate aerodynamic behaviour over the complete flight trajectory. The motion of the AWE system is included by overlaying the moving body-fitted mesh attached to the AWE aircraft over the background mesh. The Chimera overset technique connects both meshes, interpolating the solution at the overset boundary. This technique has been proven to be a robust approach to simulate the motion of an AWE system in computational fluid dynamics (CFD) simulations.

“…In another article in this field, Malz et al [15] calculated the energy profile of an airborne system using the data collected from the wind profile. In one of the latest research, Vimalakanthan [16] performed the aerodynamic analysis of Ampyx Glider. This study made a comparison between 2D steady and unsteady calculations using SU2 and OpenFOAM.…”

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.
