In other words, if spinning blades super fast doesn’t give a helicopter the lift it needs, then what does?
In: Physics
Some say flying a helicopter is immensely harder than flying an airplane. You are in control of a *lot* of things.
The blades spin fast, and they can spin even faster and still not lift up, what changes is the rotor angle. It’s much more precise than just trying to speed the engine up and down to gain altitude or land quicker.
I love explaining this side of helicopters to people with the example of sticking your hand outside the window of a car (*everyone had to do this at some point, right??)* as you’re going down the road the speed can stay the exact same, but angling your hand upwards or downwards will make your hand ‘fly’
More angle, more ‘fly’, less angle, less ‘fly’, downward angle, down ‘fly’
