(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

Rushdi, Mostafa A. (author), Dief, Tarek N. (author), Yoshida, Shigeo (author), Schmehl, R. (author)Kites can be used to harvest wind energy with substantially lower material and environmental footprints and a higher capacity factor than conventional wind turbines. In this paper, we present measurement data from seven individual tow tests with the kite system developed by Kyushu University. This system was designed for 7 kW traction power...journal article 2020

(author)Kites can be used to harvest wind energy at higher altitudes while using only a fraction of the material required for conventional wind turbines. In this work, we present the kite system of Kyushu University and demonstrate how experimental data can be used to train machine learning regression models. The system is designed for 7 kW traction...journal article 2020

Dief, Tarek N. (author), Fechner, Uwe (author), Schmehl, R. (author), Yoshida, Shigeo (author), Rushdi, Mostafa A. (author)In this paper, we applied a system identification algorithm and an adaptive controller to a simple kite system model to simulate crosswind flight maneuvers for airborne wind energy harvesting. The purpose of the system identification algorithm was to handle uncertainties related to a fluctuating wind speed and shape deformations of the...journal article 2020

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

Bechtle, Philip (author), Schelbergen, M. (author), Schmehl, R. (author), Zillmann, Udo (author), Watson, S.J. (author)We compare the available wind resources for conventional wind turbines and for airborne wind energy systems. Accessing higher altitudes and continuously adjusting the harvesting operation to the wind resource substantially increases the potential energy yield. The study is based on the ERA5 reanalysis data which covers a period of 7 years...journal article 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

Salma, V. (author), Friedl, F. (author), Schmehl, R. (author)Airborne wind energy systems use tethered flying devices to harvest wind energy beyond the height range accessible to tower-based wind turbines. Current commercial prototypes have reached power ratings of up to several hundred kilowatts, and companies are aiming at long-term operation in relevant environments. As consequence, system...journal article 2019

Bauer, F. (author), Kennel, R.M. (author), Hackl, C.M. (author), Campagnolo, F. (author), Patt, M. (author), Schmehl, R. (author)As an alternative to conventional wind turbines, this study considered kites with onboard wind turbines driven by a high airspeed due to crosswind flight (“drag power”). The hypothesis of this study was, that if the kite's lift coefficient is maximized, then the power, energy yield, allowed costs and profit margin are also maximized. This...journal article 2018

Python, Benoit (author)Pumping kite power systems are a promising way of harnessing clean energy from high-altitude winds. A large kite flies crosswind developing a strong pulling force through a tether which is connected at the ground to an electrical generator. The power output of such innovative systems is directly related to the wing aerodynamic properties which...master thesis 2017

Deaves, M.E. (author)The kite power group at TU Delft is currently researching the use of leading edge inflatable (LEI) kites for use in power generation. A thorough understanding of the aeroelastics of these kites is paramount to the development of system simulation models and optimum kite and system designs. The current lack of understanding is therefore seen as a...master thesis 2015
