- When an airfoil comes into contact with turbulent, fast-moving airflow it can create parts of the tail rotor blades to aerodynamically stall and those areas stop producing thrust. If these areas not producing thrust grow large enough the balance of thrust to torque reduces and the torque will cause the helicopter to spin.

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 ...
1 day ago · M25 reopens nine hours after ‘serious’ motorcycle crash near Dartford Crossing. The M25 has reopened after being closed for several hours due to a “serious” motorcycle crash. A helicopter pilot lost control of his Robinson R44 at an airport in Texas, USA. The spinning aircraft collided with a small plane. The pilot was lucky.
Jun 6, 2019 · A helicopter rescuing a 75-year-old woman on a stokes basket took a dramatic turn when it spun out of control Tuesday. The dizzying rescue of the injured hiker was captured on video.

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.
