Thank you Hal, for showing and explaining this type of rotorhead. It has long intrigued me of its workings. Looking at exploded parts diagrams is nice, however to have the individual components explained of its function in the whole scheme of things, is a bonus. Thank you Sir.

I stumbled across this video. Pretty cool. I had no idea that the 206 and other Bells had the straps. I thought it was only in the BO-105 and BK-117 for example. I was wondering what Bell used for the pulling load. I have experience with RC helicopters and most use thrust bearings. I didn't think full size helicopters used thrust bearings but I didn't know how they solved the problem until now. Back in the late 80s a company made a scale rotor head for model BK-117 that had a strap in place of thrust bearings. As far as I know it was the only company that did that. I just looked at your channel. Just fricken great now I have another channel to subscribe to. LOL

Many helicopters use the strap method. I know the MD 500 also has strap packs.

Is there a reason why there is no rubber bumper stop for when the rotor head see-saw's to prevent it from hitting the mast in flight with enough force to fatality tear the rotor head off (mast bumping)?
@halhobenshield5931

Not sure why there’s not something more substantial in there to prevent it. It just puts a limitation on the flight characteristics of these aircraft.

If there was, it would not be rubber. Rubber would act as a Brake, slowing down the Rotorhead, not good. The material would have to be something like a block of teflon, tough, but still flexible n slippery. In rotation, centrifugal force keeps the rotorhead horizontal. A forward or rear pushover on the cyclic will cause mast bumping, however these helicopters are not designed for acrobatic maneuvers. The Helicopters with rigid Rotor Heads can handle more loading, but do you really want to be flying a helicopter upside down?? 😳

Why do you call this a Semi Rigid Head ? It actually is a Semi Articulated Head.
@MrRexquando

Semi articulated would be a 3-blade like the Gazelle that flaps via hinge and feather hinge but lead/lag is handled by Friction damper. No teetering in a semi-articulated head.

@@halhobenshield5931 It's all about the teeter. If it uses teeter it can't be articulated and vis-versa :-) Keep up the great videos. So refreshing to see technical chops on youtube compared to a lot of producers that don't know what they are talking about even in broad strokes (Mentor Pilot, Yellow Pilot, others).
