If the tail rotor flies off to do its own thing, there's nothing to counteract the horrible spinny force acting on the helicoprer, and it starts spinning the opposite way from the main rotor.

The fact is that DaVinci did not come up with schematics for a helicopter that would actually work. Not only would his design for the wing structure fail to generate enough lift, there was no way for him to spin the wings fast enough to even come close.

When a helicopter is working correctly the engine drives the main rotor via a transmission. Because of Newton’s Third Law‘For Every Action, There is an Equal and Opposite Reaction’ this makes the fuselage want to rotate in the opposite direction to the main rotor. This is known as ‘Torque’. Think of it like drilling a hole and the drill bit sticks,...
On a conventional helicopter, the tail rotor airfoils produce horizontal thrust as they spin, just like a fan sitting next to you on a hot day. The tail rotor is driven off the main transmission so when the main rotor turns, so does the tail rotor. On the Astar that I fly, the tail rotor turns approximately 7 revolutions for every single revolution...
The loss of tail rotor effectiveness, shortened to LTE is an aerodynamic situation where the tail rotor is momentarily unable to produce enough thrust to equal the torque of the fuselage and the helicopter begins to spin. For an airfoil to work efficiently it needs clean, undisturbed air to work on, to turn at a determined rpm, and produce enough t...
Helicopters spin out of control when an issue arises from the anti-torque system on the helicopter. Be it a mechanical failure, the pilot hits something or the helicopter is being operated in conditions that can lead to the onset of it losing its effectiveness. Any condition that prevents the thrust being produced by the system to equal the torque ...
Hafner Rotachute - one-man rotor-kite for landing assault troops. Not adopted but used instead for testing in support of Rotabuggy project. Sikorsky "Hoverfly" I - service name for Sikorsky R-4 used at RAF Helicopter Training School from 1945.
One type of rotorcraft had been extensively tested and used before the war had even broken out. The autogyro, sometimes called a gyrocopter, was a typical design that all sides used throughout the war. True helicopters as we know them today weren’t developed until later.
In 1944, those young men loaded it aboard a C-46 Commando transport aircraft and hauled it halfway around the world—to Burma. There, in April 1944, 2nd Lt. Carter Harman flew history’s first helicopter combat mission. Harman was an unremarkable man with just a little culture who was thrown in abruptly among roughnecks.

Feb 21, 2024 · Helicopters were not widely used in World War II due to their early development stage, which limited functionality and reliability for combat roles. Pioneering designs existed, but technology had not advanced enough for effective battlefield integration.
