Why Helicopter Rotor Hubs Are So Complicated？

How the hell did they invent these in like the 1920s?

Add 90 degree phase lag and things get even more complicated.

@DreamsGrenadine Helicopter rides at the beach are for low intelligence tourists that don't know how Helicopters work. No one wouod willingly get into one of these if understood this.

Helicopteres are much more physically demanding and complicated to fly than jets.

Because it try to compete Nature

Add that there is precession. If the pilot moves the cyclic , the mechanical pitch up of the blade occurs 90° ahead of the desired direction of travel.

its all in the swashplate.... any genius' on cad, pm me

Hump and Pump

muitas peças para quebrar, bem perigoso.

@shiv_cybersurg SwashPlates The tilt with respect of movement of Collective and cylic One of the best mechanical engineering in the history

Jesus ... Nut

Changing electric rotors' angle was already easier to achieve electrically in eVTOLs, now they're working on variable blade pitch.

Little wonder the crashes

Cool. Would it be believable that each of these components (in terms of design and engineering) and their interconnected systems could have "evolved" separately or in a "progressive" sequence without any external input of intelligence and purpose? 👆📷

long-term helicopters will die out considering quickly progressing drone technology. It's just unnecessary complexity with too many modes of failure.

fast spin make strong vibration can break , that make balance emtion stable soft stabilzaton

Because the simple ones generally can’t fly 😂

It is called a swash plate. Rotating wings can resonate with the ground, cause gyroscopic precession, imbalance lift in forward flight, downwash, etc. 500 pages of helicopter design book had about 20 pages on basic physics, like momentum theory, and the rest is other stuff

That's too many moving parts!

Interesting... never knew there are so many more "complications" besides the rotor blades 😶

the engineering needed just to keep those blades from ripping themselves apart mid-flight is wild. articulated vs rigid vs hingeless, each solving different nightmare scenarios

The more pieces, the greater the chances of failure.

The Chinook is amazing

This is more like how its supposed to be.

engineering is outrageously under appreciated by most people in modern society

Lovely

Beautifully engineered... but reason enough for avoiding flying in a helicopter whenever you can.

wow.. so many failure points

Helicopters are really complicated flying machines. Its a super engineering

They are so complicated because no leverage spinning blades from center better with a Jet Tip and SCW. Then no need for swash plates and transmission which 1/3 of the weight this design 18 Kw/Pound.

When going forward the blades rotating into the airstream flatten out and the blades rotating away from it pitch up to maintain left/right lift balance. If this constant pitch change didn't occur the helicopter would roll over. (Hope I said that right.)

hmm... interese kaj mirinda 😸
