Slow motion video of a helicopter rotor blade

[rebolledodari]

chido

esta de poca el video

[HelicopterTraining1]

Cool video! Watching the blade flapping is very interesting!

[kirkjamestkirk]

I always thought aeroelasticity was some weird concept invented by my aerospace teachers in University to make me fail. Well, I was wrong !

[Rodrigo2838]

Can i say thats a BO-105??? It sort looks like......... damn interesting..

[Orangebike666]

That is a really amazing video of the Blade, but at first it kinda looked as though a seal was waving goodbye.

[wulihubi]

As I remember, this film is of a BO 105 in the 60's. And the tail rotor passing every fully rotation shows its typical design.

Konventional aluminum rotorblades are not flexible like this, you could see the blade going up and down like a solid bar...

Happy landings! :-)

Helicopters do NOT fly.. The Earth repels them ^^

[jeepnutnh]

@RooFx i always heard it as "they beat the air into submission" lol

[Jrstok]

@RooFx No, they beat the air into submission ;]

[shadowdrgn0]

well... i wanted to ride in a helicopter...

[d3boy2002]

Very very very very very cool

[tastycougs]

ok lads enough testosterone, this film is sorta old show me some video, used with todays materials , every wing does flex a lil even thoughs 747 400, and flexing is good, even gyro rotors flex :D

[mountjoy23]

roberto keep wasting oxygen !

[helicopterR22]

it doesnt actually flex to make less lift, it chages its angle of attack to compensate for a higher relative wind. initial increase and decrease in lift is responible for bladeflexing

[TotaLyn00b]

lol attack

[boundaryzero]

lol you dont know anything lol

[TotaLyn00b]

and u have hair? hum didnt think so :D

[djpooh28]

english pleas! lol

[jedarapa22]

I believe you're mistaken; the advancing and retreating blades do compensate for relative wind by flapping up and down (respectively? I can't remember...haven't flown in too long!). Flapping is the means by which they do change angle of attack; it is not a pitch change which compensates for the differential airspeed between the advancing and retreating portion of the rotor disk.

@helicopterR22 wait, what

[helicopterR22]

[murdockBO105]

@helicopterR22 in this case your wrong caus the horizon doesnt change his angle

[Anonymity0]

it does that on purpose. Whenver a helictoper is moving, the one moving into the wind flexes to make less lift, while the blade moving away from the wind flexes to make more lift. This is to keep the helictoper balanced while moving around.

[akspeedemon]

so, the fact that the rotor system and the helicopter are conected by one bolt doesn't bother me. That however,.....

[mountjoy23]

next time you fly commercially, sit on a wing window seat and watch the wings !

[carlsetzer]

And remember to say to yourself, these are the things that are holding the plane up.

[thibaulthalpern]

And remember to say if the wings don't flex, they break off. So, flexing is good. The whole idea of "like a rock" (Chevy commercial) is a bad idea.

[pbbmxer]

dude... that is awesum... but scary to see how much it flexes lol

[Skrewtinizer]

Amazing the forces at work... at every rotation!

[87chacha]

thats coo
