What is purpose of tilting those blades every cycle?

[schneik80]

The blades need to change their angle of attack as a group called collective pitch to cause the helicopter to rise. Tilting the blades in the video was just a way to show the kinematic movement that the swash plate mechanism can cause.

gay? why some one bothers to write comment like this is beyond me. If you don't like it move on.

@Etern4lSlay3r this is pretty bad ass dude. why would you ever say that...?

[JaghoriLover]

great job, thanks for the upload. thums up........

No stationary swash plate? And what's that bushing below the rotating swash plate with the hinged arm connected to it?

[dutto75man]

The non rotating swash plate is rotating!

[MrThundermouth]

Can someone tell me if (pitching from below the swashplate) on real helicopters use the same technic as rc helicopters? 3 Electronic mixed servos ? Otherwise I can see that this is the only correct video on youtube for rotorheads. Those other videos I saw was all wrong in some aspect.

@IndyHelis

Oh I see now, I thought that pitching(forward/backward) is achieved by tilting the whole rotor set forward.

I was just wondering at the beginning of the video why every blade tilting is changed by every cycle, but that was probably just to show the mechanism.

@TuPP3  as mentioned by schneik, changing the pitch on all three blades make it rise. changing them in one location is how you pitch or roll the helicopter itself (to lean forward or back, to lean left or right). The inputs are 90 degress ahead due to cyclic precession, meaning if you want to go forward (depending if your blades are left hand rotation or right hand) you increase the pitch on either the left side or the right of the helicopter..

@IndyHelis I noticed that too. What you're referring to is called the stationary scissor (assembly or link depending on the terminology). And the bottom of the swashplate is there, you can see the linkage attachments. So most likely they just animated it in 3D Viz and rotated the whole assembly for simplicity.

wow!!! im so amazed there r skilled people like you! this is art man!

[IndyHelis]

ummm arent you forgetting some things...? The lower part of the swashplate is missing plus the bottom "elbow" doesnt rotate. the gearbox and that articulated arm are stationary and hold the lower part of the swashplate in place which basically sets the phasing..(the timing so when u push forward on the stick it goes forward and not another direction instead)
