WebThe tail rotor plays an important role in helicopter aerodynamics. As the engine causes the main rotor to spin, each angular impulse generates a torque on the main rotor. According to Newton’s third law, the same angular impulse and torque is exerted against the engine and the body of the helicopter, but in the opposite direction. WebAll helicopters have two rotors that generate the lift and thrust required to steer the aircraft as well as stabilize the helicopter against unwanted rotation. Attached to the engine are …

How Fast Do Helicopter Blades Spin? Executive Flyers

For helicopter, "autorotation" refers to the descending maneuver in which the engine is disengaged from the main rotor system and the rotor blades are driven solely by the upward flow of air through the rotor. The freewheeling unit is a special clutch mechanism that disengages any time the engine rotational speed is less than the rotor rotational speed. If the engine fails, the freewheeling unit … WebAutorotation is a state of flight in which the main rotor system of a helicopter or other rotary-wing aircraft turns by the action of air moving up through the rotor, as with an autogyro, rather than engine power driving … WebA helicopter works on the principle of aerodynamic lift - an upwards force that opposes the weight of the helicopter and holds it the air.

"WebAs the helicopter falls, the resistance from the air pushes the blades up into a slanted position. In this position, the air under one blade is pushing one way and the air under the other blade is pushing the opposite way. These two forces of air push the blades around and make it spin. The faster the blades spin, the less the air can get by ... " - How does a helicopter spin
