Before embarking on his helicopter endeavors, Focke was already a respected figure in German aviation.
In 1924, he co-founded the Focke-Wulf Flugzeugbau AG, an aircraft company that initially focused on designing and producing commercial aircraft.
However, Focke's true passion lay in exploring unconventional aircraft designs, particularly those capable of vertical flight.
Driven by this vision, he began to dedicate his efforts towards developing a practical helicopter.
The Focke-Wulf Fw 61: A Masterpiece of Engineering
The Focke-Wulf Fw 61, first flown in 1936, was a groundbreaking achievement in aviation.
Unlike Sikorsky's VS-300, which relied on a single main rotor and tail rotor configuration, the Fw 61 employed two laterally mounted rotors, positioned on outriggers extending from the fuselage.
This innovative design eliminated the need for a tail rotor, as the counter-rotating main rotors counteracted torque, providing exceptional stability and control.
The Fw 61 was powered by a single Bramo Sh.14A radial engine, which drove both rotors through a complex system of gears and shafts.
This meticulous engineering allowed for independent control of each rotor, enabling the pilot to precisely maneuver the aircraft.
Its performance was remarkable for its time.
The Fw 61 achieved numerous world records, including altitude, speed, and flight duration.
Some sources claim that it demonstrated full controllability in all phases of flight, a feat not yet fully achieved by Sikorsky's VS-300 at the time.
