Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Focke-Wulf Fw 61 was the first functional helicopter, first flown in 1936. It was also known as the Fa 61, as Focke began a new company -- Focke Achgelis -- after development had begun. Through his work on the C.19 and C.30 autogyros built by Focke-Wulf under license from Cierva Autogiro, as well as the experience gained through development of the Fw 186, Professor Henrich Focke had come to the conclusion that the inadequacies and limited serviceability of autogyros could only be eliminated by a real helicopter. He and engineer Gerd Achgelis started the design for this helicopter in 1932. A free-flying model, built in 1934 and propelled by a small two-stroke engine, brought the promise of success. Today, the model can be seen in the Deutsches Museum in Munich.
