STEM Aviation Lesson 2-3: Helicopter Flight Controls and Surfaces

As a helicopter is a very different type of flying machine, this lesson examines the forces (and torques) inherent in flying. It also discusses how the unwanted torque is balanced by a counter-torque system and how the main rotor provides for both vertical and horizontal motion. Basic helicopter control mechanisms are also introduced.

This video really needs to cover the phase lag aspect pf the rotor assembly. Because of the gyroscopic effect, a pitch change in the cyclic produces a force that occurs 90° later in the rotation. If you wanted to tilt the rotors forward, you would move the cyclic forward but the blades would pitch up 90° before the rear or 6 O'clock position (pitch up occurs at the 9 O'clock position or left side relative to the pilot). This causes the rotors to tilt up at the 6 O'clock position or 90° after the pitch change occurs. This may cause confusion as it isn't very intuitive, but it's still a critical aspect for flight in a rotary wing aircraft.

Awesome explanation and graphics

This is not 100% accurate. Because of the phase lag of the rotor blade.

Thank you a lot

Excellent. I love being in a chopper but I'd never want to fly one (maybe, okay, if I was 20 and had faster reaction time and more coordination. My math would stop me cold, however.)

Thank you bro

Damn!! now i wanna build one😅😅...

ought to use 3-dimensional illustrations
