ENGLISH
An unmanned, electric, autonomous aircraft travelling at 75 kilometres per hour lands gently on the roof of a moving car. For the first time, researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have successfully demonstrated a technique developed for this purpose. The system could be applied to ultralight solar-powered aircraft that complement conventional satellite systems while flying in the stratosphere. Eliminating the landing gear significantly increases the payload capability of a solar-powered aircraft - it is easier to land during crosswind conditions, making landings in unfavourable weather conditions possible.

The work was partly funded by the EU project 'EC-SAFEMOBIL' and complemented the group's activities in the field of stratospheric flight research. For example, last year an unmanned glider was successfully launched from a high altitude balloon at 20 kilometres in the scope of the High Altitude Balloon Launched Experimental Glider (HABLEG) project.

An unmanned, electric, autonomous aircraft lands gently on the roof of a moving car at 75 kilometres per hour: scientists at the German Aerospace Center (DLR) have successfully demonstrated the technology developed for this purpose for the first time. However, this system is not to be used on the road, but at high altitude. By omitting the landing device, the available payload of ultra-light solar aeroplanes can be significantly increased. This would allow the fragile aircraft to fly autonomously in the stratosphere for longer periods of time and supplement conventional satellite systems. At the same time, landing with crosswinds will be significantly simplified. This will also enable landings in poor weather conditions and the system will remain usable all year round.

The work was supported by the EU project "EC-Safemobil" and complements the activities of the aerial robotics group in the field of high-altitude platforms. As part of the HABLEG project, DLR scientists have already succeeded in launching an unmanned glider from a high-altitude research balloon at an altitude of 20 kilometres.
