Bell Uh-1 Super B

Recommended Posts

The Bell 540 rotor system, used on the UH-1C is the source of the rotor system without a stab bar. If you look at the 214, you can the progression from that start.


The composite blades were installed on a variety of UH-1 models - they were actually manufactured by Kaman.


Bluebird Helicopters were out of Cougar, Washington; and later purchased a fleet of CH-54B helicopters that are now owned and operated by HTSI in Oregon.

I know it's not a 214, and the pictures look more like a 204 than a 205, so I think helirider and DGP are right, it's a UH-1B with the cobra blades. I looked up a couple N numbers and they're model type is still a UH-1B, but they're restricted, and they don't give any info on the powerplant or the modifications done.
