Airborne wind energy (AWE) systems convert wind energy into electrical energy using autonomous tethered flying devices. Deemed a potentially game-changing solution to clean and sustainable energy generation, AWE is increasingly attracting the attention of governments, policymakers and industry worldwide. AWE technology can significantly reduce the levelized cost of energy (LCoE) by eliminating (i) the drive-train installation, (ii) a large part of the rotor blades, (iii) the tower, and (iv) the foundation, which make up for about 50% of the conventional turbine costs. On the other hand, the development of this technology is also facing substantial technical challenges. Important aspects are, for example, autonomous, efficient, reliable, safe, and uninterrupted operation of AWE systems and their interconnection with the future power grid.
We cordially invite original manuscripts presenting recent advances in this important and interdisciplinary research field with particular focus on but not limited to the following:
- Aerodynamics, aeroelasticity, and structural dynamics;
- Flight dynamic modeling;
- Flightpath planning and control of AWE systems;
- AWE design optimization;
- Higher altitude wind resources;
- Experimental testing of prototypes;
- Efficiency enhancements (by, e.g., intelligent design and/or control);
- Nonlinear, optimal, and fault-tolerant control strategies;
- Fault detection methods and condition monitoring approaches;
- Robust, fault-tolerant and flexible grid connection/integration (e.g., grid-supporting, -feeding, -forming including black start capability);
- Economic and market analysis;
- AWE policy-making, environmental impact, and societal acceptance.
The Special Issue will present cutting-edge research results connected to AWE technology as a basis for enduring operation. All research results must be presented in a mathematically thorough (e.g., in state space) but understandable manner to encourage insights and re-implementation by the readers so that the knowledge basis is shared, spread, and extended to promote AWE systems to the market. All results should be validated by simulation and measurement results (if possible).

Abstract: This paper presents an analytical model for calculating the average flow velocity and radii of the annular wake developed downstream of a crosswind kite power system. The model is formulated based on the widely used Jensen's model (Technical Report Riso-M; No. 2411, 1983), which was developed for conventional wind turbines, and thus has a simple form. Expressions for the dimensionless wake flow velocity and wake radii are obtained by assuming self-similarity of flow velocity and linear wake expansion. Comparisons are made between numerical results from the proposed model and those from high-fidelity CFD simulations. The level of agreement was found to be reasonably good. Such analytical models are indispensable for kite farm layout design and optimization, where aerodynamic interactions between kite systems should be considered.
