How does a helicopter fly?

.V.P support us on Patreon.com. So we will be able to add one or more members to our team to be able to produce 2 educational videos per month.

Helicopters are truly flying machines. They can take off and land without needing an airstrip. They can hover. They can maneuver in any direction in a 360 degree space. This video will reveal the complexity and science behind a flying helicopter. After going into the physics behind a flying helicopter, you will also understand why a helicopter pilot does an incredibly complex job.

How does a helicopter fly?

Illustrated presentation of the principles of helicopter flight, the controls available for its piloting, their impacts on the rotor head, the different configurations of anti-torque rotors implemented on the aircraft

Piloting a helicopter: a three-dimensional balancing act

As the blades of a helicopter rotor spin, they generate lift that allows the helicopter to fly.

By changing the angle of attack of the main rotor blades, the helicopter can be pitched, descended, banked or rotated.

By changing the angle of attack of the tail rotor blades, the helicopter can be turned in place or stabilized in forward flight.

When the pilot pulls on the collective (general pitch), he symmetrically increases the angle of attack of the main rotor blades: the helicopter climbs. When he presses on it, on the other hand, he decreases the angle of incidence and thus lowers the helicopter. Contrary to popular belief, it is therefore not the speed of rotation of the rotor which varies to make a helicopter climb or descend. This control is located to the left of the pilot's seat.

With the cyclic, the pilot changes the angle of attack of the main rotor blades asymmetrically. The helicopter tilts left, right, forward or backward. This control has the shape of a joystick in front of the pilot.

With the pedals, the pilot modifies the angle of attack of the blades of the tail rotor. He thus maintains the course or turns the device on the spot. This control is characterized by 2 pedals at the pilot's feet.
