A second Luftwaffe's Fl V21 model followed for my own personal collection at home. It is believed that the firm was founded in Berlin in By this time, however, Flettner had developed the idea of counter-rotating, intermeshing twin rotors.
Many of his advisers thought that the airflow disturbed by the intermeshing blades would make this system less efficient than one using a single rotor; but Flettner believed that any problems thus encountered would be more than offset by the reduced drag resulting from having no external rotor-carrying structure. His pioneer work is often overshadowed by the more publicised activities of his contemporaries Heinrich Karl Johann Focke and Igor Sikorsky; yet Flettner's helicopter, was far superior to the Henrich Focke's FW and made a successful free flight several months before Igor Sikorsky's VS began tethered flights.
Following pictures taken at Pfaffenwiesbach a district of the municipality Wehrheim, Germany. This artistic wall painting cultural monument, created by the local municipal council in memory of Anton Flettner who was the village teacher in Pfaffenwiesbach from to Anton Flettner's partner and confidant was Dr.
Kurt Hohenemser, a brilliant and thorough engineer who developed the details necessary for the helicopter's success. Hohenemser's father was also Jewish, yet the pair remained unharmed during their tenure together throughout the War as they worked to develop the helicopter for military use. While the final product could be factory assembled, Anton Flettner and his partner Dr. Kurt Hohenemser insisted that they were the only ones who were capable of assembling the complex intermeshing rotor gearbox assembly.
However, plans for helicopters mass production were made, the project was disrupted by the destruction of the designated factory by Allied bombing. After , Flettner, along with many other aviation pioneers, was brought to the United States as part of Operation Paperclip. His company was not commercially successful, but his work was shared with the Army Air Corps. Many of his designs, such as intermeshing rotor concept, saw widespread use in a series of postwar helicopters built by Kaman for the US Navy and USAF.
