The multi-body aircraft technology was developed by aerospace engineer Alexander Köthe, M.Sc., as part of his Ph.D. project at the Technische Universität Berlin. As Chief Engineer at Project AlphaLink, he is in charge of the design of the individual aircraft and the development of the joint technology to connect these aircraft. Alex also works on the flight control system to enable autonomous coupling or decoupling in flight mode and to guarantee the autonomous operation of the joint flight formation.


Dr. Daniel Cracau manages the project. His diverse professional experiences from academia, the private sector and international organizations complement the engineering excellence behind Project AlphaLink. Daniel’s responsibilities are strategy, project planning, and administration.


Project AlphaLink currently cooperates with TU Berlin.

Public Appearances

Chief Engineer Alexander Köthe informed the audience about the latest developments during the HAPS4ESA Workshop in Leiden in February 2019. The AlphaLink approach of coupled aircraft stood out among a range of conventional HAP technologies and programs presented at the event.

In the focus session on HAP technologies, AlphaLink contributed to the ESA Earth Observation Φ-week on EO Open Science and FutureEO in a 20-minute presentation.

At the IAC 2018 in October in Bremen, AlphaLink was selected to participate in the IAF Startup Pitch Session as one of ten startups from all over the world.

In July 2018, AlphaLink won the 3rd prize in the Life Sciences & Technology category of the Research to Market Challenge.

At the ILA  Berlin Airshow in April 2018, AlphaLink exhibited a prototype of its integrated flight control system Smart FC(R) and informed visitors about the technology of unmanned connected aircraft. The two co-founders Alex and Daniel also gave on-stage talks at the ILA Future Lab and the ILA CareerCenter. In a 3-minute report broadcasted by RBB Abendschau, AlphaLink celebrated its first appearance on TV on April 27, 2018.

In an invited talk, Daniel Cracau represented AlphaLink in front of international visitors from the Space Community at the New Space Vision Conference 2018 in Berlin.

AlphaLink was awarded Innovative Drone Hero Europe 2018 at the Commercial Expo UAV Europe in Amsterdam. In the contests among participants from 13 European countries, the unique approach and the potential of AlphaLink convinced the jury: “Although it is still in a concept phase, the solution of Alphalink is very innovative. Their pitch was the best overall. They have found a very specific innovation, that could be a real game changer when implemented successfully. This is innovation at its best, no doubt.”

The advances of Project AlphaLink were presented at the Space Tech Expo Europe 2017 in Bremen, Germany. See Interview and Presentation

At the International Aerospace Exhibition and Conference (ILA) 2016 in Berlin, Germany, Project AlphaLink exhibited under the former project name X-Pede 2. See Interview (German)
