Rapp, S. (author)Airborne wind energy (AWE) is a novel technology that aims at accessing wind resources at higher altitudes which cannot be reached with conventional wind turbines. This technological challenge is accomplished using tethered aircraft or kites in combination with either onboard or ground-based generators. In the former case, the kinetic energy of...doctoral thesis 2021

(author), Géczi, M. (author), Kempers, M.X. (author), Schmehl, R. (author)Generating renewable energy on Mars is technologically challenging. Firstly, because, compared to Earth, key energy resources such as solar and wind are weak as a result of very low atmospheric pressure and low solar irradiation. Secondly, because of the harsh environmental conditions, the required high degree of automation, and the exceptional...journal article 2021

Airborne Wind Energy (AWE) is an emerging renewable energy technology that aims to replace the use of fossil fuels for energy production on an economical basis. A characteristic feature of the various AWE concepts is the use of tethered flying devices to access wind energy at higher altitudes where the wind is more consistent. Over the past...book 2019

van der Vlugt, R. (author), Bley, A.C. (author), Noom, Michael (author), Schmehl, R. (author)The traction force of a kite can be used to drive a cyclic motion for extracting wind energy from the atmosphere. This paper presents a novel quasi-steady modelling framework for predicting the power generated over a full pumping cycle. The cycle is divided into traction, retraction and transition phases, each described by an individual set...journal article 2019

Thedens, P. (author), Bungart, Merlin (author), Schmehl, R. (author)We present a computationally efficient steady-state solution method to model the aeroelastic deformation of a ram-air kite for airborne wind energy applications. The kite’s weight in comparison to the aerodynamic forces is small which justifies a quasi-steady analysis, neglecting gravitational and inertial force effects [1]. The approach is...abstract 2019

Grete, C. (author)The fundamental working principle of kite power generation is straightforward: a fast-flying kite pulls a tether from a drum, which drives a generator. At the maximum reel-out length, the kite is de-powered and pulled back, to initiate a new pumping cycle. The objective of this innovative technology is to make electricity generation affordable,...journal article 2014
