jjsemperfi Posted September 30, 2012 Posted September 30, 2012 So... Looking at the UH-1Y's blades..... Why did they design the blades so that they attach to these pieces that stick out a couple feet from the hub. It looks like they just eliminated the blade root (because it doesn't do much anyways) and just started the blade further out. 1 Quote
Flying Pig Posted September 30, 2012 Posted September 30, 2012 Doesnt the MD900/902 have the same concept? Quote
adam32 Posted September 30, 2012 Posted September 30, 2012 Yup the 900/902 does...but who was the first to use that design?? A brownie point to the first person with the right answer... Quote
jjsemperfi Posted September 30, 2012 Author Posted September 30, 2012 Huh, well I have no clue. What's it for anyways? Quote
Flying Pig Posted September 30, 2012 Posted September 30, 2012 ^Thats what I was thinking darnit!!..... Oh well, you won Quote
superstallion6113 Posted September 30, 2012 Posted September 30, 2012 The CH-53E uses blade extenders that mount between the blade root end and the main rotor hub as well. Creates more useable lift using the same size blade as the CH-53A/D had. Quote
Hotdogs Posted September 30, 2012 Posted September 30, 2012 I'm assuming It's part of the bearing-less hingeless rotor system. That blade root allows the Yankee's blades to lead, lag, twist, and flap without the use of multiple dampeners and hinges. Reducing maintenance workload. Quote

Great...... now you have a bunch of lazy-a$$ wingers sitting around with nothing to do but thumb through hairstyle and Oakley magazines! Figures! (8yr 0331/Sgt) 1 Quote
