When communities learn how kite-based systems work and understand their environmental benefits, they tend to view the technology with interest and openness. Greater public understanding of airborne wind energy (AWE) could open doors for broader acceptance.

These insights come from a PhD study by Helena Schmidt, who completed her doctorate at Delft University of Technology on October 31, 2025, after 4.5 years of research on how communities perceive and accept airborne wind energy systems. Her work offers one of the first in-depth perspectives on how people respond to airborne wind energy in real settings.

Compared to traditional wind turbines, airborne systems raise fewer concerns about noise and landscape impact. At the same time, AWE remains relatively new, and public familiarity with it is still limited. More communication, education, and visible demonstrations will be essential to help communities understand the technology’s potential and build lasting trust.

This growing awareness opens great opportunities to accelerate the energy transition. Airborne wind energy can harness stronger and steadier winds at higher altitudes while using less material and space than conventional turbines. These characteristics make it a flexible and sustainable addition to the renewable energy mix, particularly in areas where installing large wind turbines is not feasible or the local communities oppose them.

Helena’s research also highlights the importance of local engagement. Communities that were informed early and had opportunities to ask questions or observe demonstrations showed higher levels of acceptance and confidence in the technology. This underlines that trust and dialogue are just as important as technical performance when introducing new renewable solutions.

Helena completed her PhD on October 31, 2025, under the supervision of Dr Roland Schmehl, one of the founders of Kitepower. Kitepower contributed to the research by providing input and operational data from its test site in Bangor Erris, County Mayo, Ireland. The collaboration helped connect academic research with real-world experience, giving a more complete understanding of how airborne wind systems are perceived by local communities.

At Kitepower, we congratulate Helena on this achievement and thank her for her valuable contribution to the field. Her work strengthens the foundation for socially responsible and widely accepted deployment of airborne wind energy. Thanks to studies like this, businesses and consumers can look forward to faster access to clean, flexible, and sustainable energy from kites.

Kite as a Sensor: Wind Estimation

The method combines onboard measurements such as kite motion, tether tension, and aerodynamic forces with a dynamic system model using an Extended Kalman Filter. The result is accurate estimation of wind speed and direction at flight altitude, along with insights into the kite’s behavior and system state in real time. Unlike conventional approaches that rely on ground-based sensors, this approach lets the kite act as its own airborne weather station.

LiDAR Validation

To validate the method, the estimations were compared with lidar measurements from Kitepower’s test site in Bangor Erris, Ireland.The agreement of these results across varying conditions confirm that kites themselves can serve as reliable sensors of the wind environment, providing accurate real time measurements.

The Impact for Kitepower

This real-time wind estimation has important implications for Kitepower systems. It enables more precise flight control, safer operation in changing conditions, and a better understanding of how the system responds to gusts and turbulence. This leads to more optimized and automated flights, increasing its efficiency, reliability and power output by adjusting its flight as conditions change in real time.

Real-Time Deformation Modeling

A major focus of Poland’s research is how flexible membrane kites deform under aerodynamic loading and how this deformation impacts flight behavior and control. He has developed computationally efficient deformation models that predict how the kite’s surface responds in flight conditions. These models factor in structural tension, pressure distribution, and real-time flight dynamics.

His work will enable real-time integration of deformation data into flight control algorithms, improving the kite’s maneuverability, flight stability, and energy yield—especially in turbulent or rapidly changing wind environments. The deformation predictions are vital for ensuring the kite maintains optimal shape throughout its pumping cycles.

Wind Tunnel Validation at TU Delft

To validate these models, Poland conducted groundbreaking experiments at TU Delft’s Open Jet Facility, one of Europe’s leading low-speed wind tunnels. These tests included wind tunnel trials with inflatable, rigidized soft kites, replicating realistic in-flight pressure and tension conditions.

High-resolution Particle Image Velocimetry (PIV) and photogrammetry were used to measure both the airflow and the shape deformation of the kite in detail. The data gathered allowed Poland to calibrate his models, reducing the gap between simulation and reality. His validation results confirm that such simulation tools can be reliably used to predict and optimize kite flight performance.

Why It Matters for Kitepower

• Realistic control models: Incorporating deformation into simulations leads to more precise predictions of lift, drag, and control response.
  
• Flight optimization: Understanding how the kite deforms in real time allows control systems to optimize the power cycle, increasing energy output and durability.
  
• Hardware-light solutions: Combining accurate modeling with minimal sensors reduces system complexity—an essential advantage for mobile wind energy units.
  

In short, Jelle Poland’s research on real-time state estimation and aerodynamic deformation provides the technological backbone for autonomous, high-performance kite power systems. His work is not just theoretical—it’s physically tested and directly applicable to commercial energy systems being deployed by innovators like Kitepower.
