Dr. Duc H. Nguyen has obtained funding to analysis Airborne Wind Power Techniques, aiming to enhance their security and effectivity for potential commercialization and a big function in reaching the UK’s net-zero emissions.
Drones could possibly be essential in reaching the UK’s net-zero targets by harvesting wind vitality. Dr. Duc H. Nguyen, a Lecturer in Flight Dynamics and Management on the University of Bristol, has obtained a £375,000 grant from the Engineering and Bodily Sciences Analysis Council (EPSRC) to additional discover Airborne Wind Power Techniques (AWES).
By tethering a drone to a floor station, AWES harvests wind energy at larger altitudes than standard wind generators. The excessive wind pulls the drone away from the bottom station, driving the generator, and producing electrical energy.
This expertise can profit the UK’s vitality sector by decreasing its carbon footprint, offering offshore and onshore flexibility, and enhancing the power to function in distant areas.
To generate essentially the most energy, AWES should fly in intricate patterns whereas subjected to robust aerodynamic forces. This association creates a posh system with delicate dealing with traits – a slight miscalculation might ship the drone tumbling to the bottom.
That is the problem that Dr Nguyen and his collaborators hope to unravel throughout this mission. By enhancing AWES security and effectivity, he hopes the mission will pave the way in which for AWES commercialization.
Potential and Pitfalls of AWES
Dr Nguyen, from the Faculty of Civil, Aerospace and Design Engineering, defined: “Airborne wind vitality has monumental potential and is anticipated to generate €70 billion per 12 months price of electrical energy by 2050. Nonetheless, it’s nonetheless an rising expertise. In lots of circumstances, a trade-off has been made: new designs have been quickly deployed for check flights earlier than their flying traits are totally understood. This has prevented many AWES prototypes from reaching full capability in operation, resulting in early termination of this system and hindering commercialization. This mission seeks to deal with this problem by way of the usage of bifurcation and continuation strategies.”

These numerical strategies have been efficiently utilized in plane dynamic research to foretell harmful behaviors resembling pilot-induced oscillation, flutter, and spin.
Dr. Nguyen concluded: “By changing present strategies with bifurcation strategies, AWES can obtain important value financial savings and improved efficiency that can in the end deliver this expertise nearer to commercialization.”
Along with the EPSRC funding, the mission additionally advantages from collaborations with two main gamers within the sector, Norwegian startup Kitemill and College Carlos the III of Madrid.
Thomas Hårklau, co-founder and Chief Govt Officer of Kitemill, added: “The initiation and profitable funding of this AWES mission is a vital growth within the renewable vitality sector. AWES expertise, with its distinctive materials effectivity and better vitality yields, has the potential to turn out to be a dominant pressure within the vitality business. We’re excited to collaborate with Duc Nguyen and Bristol College on this initiative. This mission not solely advances the UK’s net-zero mission but additionally secures British competence on this rising sector. Collectively, we purpose to deal with present challenges and pave the way in which for the commercialization of AWES.”
