I am pleased to announce that the expert for aerodynamics and extreme athletes, Prof. Dr. H.C.-Ing. Eric Helter has joined the Bülk development!
How did this collaboration come about?
Fritz Horsthemke and Jörg Basler, both active in extreme sports, thought that Eric could have a great interest in the aerodynamics of velomobiles. They made contact and I had the honor of meeting Eric in person.
To be honest, I would never have dared to approach him because, given his impressive list of projects and activities, it seemed unlikely that he would deal with the seemingly modest topic of velomobiles. But things turned out differently.
To Eric Helter:
Prof. Dr. H.C.-Ing. Eric Helter is an aerospace engineer / civil engineer and managing director of ahw Ingenieure GmbH. He specializes in bionic material optimization and aerodynamics. Since 2015 he has been teaching in the English-language master's program at the DIA Bauhaus Campus and at Boston University.
Eric has also successfully worked on optimizing aerodynamics for GT3 cars (Lamborghini, KTM, Porsche and more).
He actively participated in the 24-hour bicycle race on the Nürburgring race track to support a foundation for spinal cord research and educational projects in Senegal.
To my great surprise, Eric offered his friendly support for the Bülk development. With the help of his team Rilind Sadiku and Egor Kuzmin, the Bülk MK1 was scanned and aerodynamically examined in a CFD analysis.

Eric's first assessment of aerodynamics filled me with pride because he certified that the Bülk had excellent aerodynamics. It would require considerable expertise and effort to achieve improvements here. It was also unclear whether these improvements would even be noticeable in everyday life.
Nevertheless, Eric had different ideas and began to calculate variants. Such calculations require significant computing power and time and are a process in which insights cannot be easily forced.
In an upcoming article I will report how this story continues.
