@gezelle007 The 429 entered production after it's certification in July last year. The first production ships were assigned as demonstrators and trainers for the Bell Helicopter training academy. One was also delivered to the launch customer last February. Bell expects to build only 25 429 this year since business in the industry is slow.
@gezelle007 Yep, it's pretty much the same principle. The 412 has two superimposed titanium yokes that constitute the main rotor head. As for the 429, it's two superimposed composite yokes. I don't know the exact specifics of the 429 rotor head but I know that much at least.
The Main Rotor of the 429 is comprised of two yokes superimposed on one another, thus two of the 4 blades are flying slightly higher therefore giving the illusion of shakeyness.
Hi there, can you tell me, if you can, what are the aerodynamics advantages of the superimposed yokes? Maybe a cleaner air each time each blade crosses the path? Should that brings more vibrations to the main rotor hub if not well calibrated and since it's more complex, calibration it's more difficult.
I don't know if there are any aerodynamic advantages in having a superimposed yoke. What I was told was that it is much cheaper to fabricate and that it was a much more predictable design. Other Bell products use this configuration as well such as the 412 and 430. As far as the 429 is concerned, The rotor system seems to be very effective as it has acheived speeds of over 160kts without any vibrations during testing. From what i have heard, the ride is smooth throughout every phase of flight.
The JetRanger lives on in modern form. Love it.

I think everybody goes for BA-609 Flight .Private Jet are much safer than Copter.But this is mix of Copter & Private Jet.

maybe its the Pilot not the aircraft thats shakey

Another fail as the B-427? looks to shakey have to work a lot to compite with Sikorsky and Eurocopter.

Yeah I was there outside that day.
I'm actually working on the 3D Illustrations (exploded views) for the chapter of the maintenance manual regarding the main rotor as I'm typing this.
It is just an incredible machine. Fantastic piece of engineering I can tell you.
