Günther W. Jörg (born March 9, 1927 in Zweibrücken ; † November 24, 2010 in Reinheim ) was a scientist and researcher who devoted his life to researching the ground effect and the development and construction of ground effect vehicles based on the ram principle.

Jörg was a development engineer at the group of companies Bölkow , Heinkel and Messerschmitt in the " Development Ring South " in Munich for VTOL systems and aircraft. He worked on both prototypes of the vertical take - off vehicle VJ 101 C and later the VC-400 -VTOL project in Speyer .

After moving to VFW Fokker in Speyer am Rhein, Jörg was responsible for the management of the Speyer / Hockenheim airfield . Parallel to his professional activity, Jörg devoted himself to the research and development of the hitherto largely unexplored ground effect. As part of his professional activity, including as assistant to the then plant management of VFW Fokker, he had significant contacts to Alexander Lippisch and accompanied his ground effect research using the single-wing RFB X-113 .

Evaluations and observations of the results of the test flights then led to the improvement of the flight behavior in the ground effect through the tandem wing concept.

With his own development of the tandem airfoil flair boats (TAF system), he created a new, fast, very economical transport system on the waterways that achieves long ranges at high speed. Jörg made numerous experiments in the wind tunnel and with remote-controlled models and between 1963 and 1974 researched the basics for this new transport system. With the help of computer calculations, he determined new profiles for the ground effect. These inherently stable, aerodynamic vehicles are only controlled with rudder and throttle, like motor boats. The stability is achieved at both low and high speed, and therefore a bank angle of up to 30 ° is also possible when turning. This gives great maneuverability, which is significant for safety during ground effect flight.

A total of 16 different, manned vehicles of different sizes in different materials and constructions were built and successfully long-term tested in different climates and in different seasons with a large number of drive systems, as well as in different sea conditions.

As early as 1974 this "Tandem Airfoil System" was classified as a motorboat by the German Ministry of Transport . Therefore, approval and qualification requirements correspond to the requirements of motor boats.

For his pioneering work in modern engineering, GW Jörg was awarded the most valuable private science award in Germany. In 1984 he received the " Philip Morris Research Prize for the New Transport System of the 21st Century".
