Deutsche Windtechnik's ADLS performed very well in each of the test situations. In addition to the audit that was passed approximately four weeks ago, the overflight test was the last major hurdle for the type test of Deutsche Windtechnik's ADLS.   

Special drones and aircraft test ADLS functionality

The overflight test was developed, managed and monitored by airsight GmbH, which was authorised by the German Federal Ministry of Transport and Digital Infrastructure as the first body to test ADLS systems that use transponder signals. The first part of the overflight test was carried out using a drone that was specially developed to test transponder-based ADLS systems (developed and built by Leichtwerk Research GmbH). Above all, using the drone allowed the simulation of critical low-altitude situations that were modeled on the flight maneuvers of rescue helicopters. The functionality of the ADLS with aircraft above the wind turbine had already been demonstrated two days earlier by an extensive overflight test with an aircraft. airsight GmbH, which is responsible for the type test, will carry out another overflight with an aircraft in the coming days.

The focus is on safety, quality and reliability

Deutsche Windtechnik's project partner for the ADLS is f.u.n.k.e. Avionics GmbH. The company specialises in developing and manufacturing avionics devices and system solutions in the areas of communication, navigation and display. For example, a jointly developed transponder reception and evaluation technology was used to reliably transmit the data generated by the overflight test process. The approximately 800-page system documentation, which was created in the preceding months by the engineers at Deutsche Windtechnik and f.u.n.k.e. Avionics GmbH, was also submitted for auditing. The goal of this pioneering development and testing work is always to design and manufacture a safe and reliable ADLS that fulfils the highest quality criteria. This is also reflected in the last step of the type test: The renowned independent standards organisation CSA-Group was chosen for the current ongoing audit of the CE marking of the ADLS. Once this has been completed, nothing stands in the way of issuing the type test.

Proven partner for the entire ADLS lifecycle

"Deutsche Windtechnik is preparing for a large number of wind turbines to be equipped with ADLS and has created appropriate resources in its specialist departments," said Jasper Salzwedel, contact person for ADLS at Deutsche Windtechnik. "An installation of Deutsche Windtechnik's ADLS can cover turbines from multiple manufacturers and span multiple wind farms, so the experience and independence of our service team can be used to its full effect. We stand by the operators with our comprehensive technical expertise during the entire lifecycle of the ADLS."
