Did you know helicopters flew several types of missions during WW2, including observation, transport, and medical evacuation? The Sikorsky R-4 powered by a radial engine was the U.S. military's...
The Second World War usually doesn't evoke thoughts of helicopters. For the most part, aircraft associated with the war involves fighters and bombers.

Best. Euripidaristophanist • 3 yr. ago. The rotors spin one way, and because physics, that pushes the helicopter itself into spinning in the opposite direction. The tail rotor counteracts this spinny bullshit, and keeps the helicopter pointed the right way.

The precursor to the modern helicopters was undoubtedly the autogyro. An autogyro or gyrocopter is a craft that uses a rotor to generate lift. But unlike a modern helicopter, autogyros don’t apply power to the rotor blades. Instead, they rely on the aircraft’s forward motion and air passing through the blade to make them spin. They can get their fo...
The Fw 61 was a technology demonstrator built in Germany before the beginning of WWII. It was an autogyro design, but the company would use the lessons it learned from the program to build true helicopters. The Focke-Wulf looked and flew more like an airplane than a helicopter. It needed some forward speed to fly. It had two large rotors, each moun...
With the lessons that they learned from the Fw 61 gyrocopter, Fock-Wulf became Focke-Achgelis and began focusing more of their design expertise on performance and capability. The company may be best known for the Fw 190 fighter, but they worked hard to develop various rotorcraft as well. The Fa 223 began life as the Fa 226 Hornisse, or “Hornet.” It...
Focke-Achgelis was not alone in their development of rotorcraft for Nazi Germany. During the same period, Anton Flettner was working on similar designs. He started with the single-seat Fl 265 prototype. Six were built starting in 1939. But the resulting Fl 282 “Hummingbird” was definitely more interesting. Flettner built 24, and they were used by b...
Most of the rotorcraft from World War II have more or less become footnotes in history. Gyrocopters are still used today, but they are limited to small enthusiast groups and home-built kits. The companies that designed those German helicopters? Long gone. But in America, a Russian immigrant from Kiev named Igor Sikorsky was polishing a design that ...

Mar 25, 2013 · The rotors rotated in opposite directions, cancelling out the torque that would otherwise tend to spin the aircraft in flight. Like modern helicopters, the Fw 61 could vary the pitch of the blades for directional control, but vertical control depended on using the throttle to vary the rotor rotation speed (most helicopters maintain relatively ...
