The dataset describes a test flight conducted on 9 October 2025 at Kitepower's test site in Bangor Erris, Ireland. One of the objectives was to measure the deformation of the wing in flight, using digital image correlation photogrammetry, supplemented by span measurements obtained through ultra-wideband (UWB) modules. The dataset includes: Position, Orientation, Velocities, and Accelerations: Recorded at two of the kite’s central struts using Pixhawk IMU+GPS systems, encompassing translational and rotational kinematics. Airflow Measurements: Collected using a pitot tube and wind vanes to measure angle of attack, sideslip angle, apparent windspeed and airspeed temperature. The sensor was installed on a bar in the front bridle lines of the kite. Ground Station Measurements: Measured at the ground station, tether length, tether force, mechanical power, mechanical depower, reelout speed. Control Inputs: Depower and steering inputs. Lidar Data: Collected at a 1-minute resolution, acquired with a Windcube v2.
