Wooden Helicopter Rotorblades

[skyguynca]

I am looking for any plans that show the construction of wooden rotorblades for helicopters. I have tons of stuff to trade contact me by email off list.

Try Monte Hoskins, his email address is: montecraig@juno.com and his address is
9644 Rd. 28 1/2, Madera, CA 93637. He sells plans for wooden rotorblades for $35.00.
(Same guy that sells plans for the 3DRV).

I have got his plans but they are for gyro's, the 8H12 airfoil, I am looking for the NACA0012 symetrical helicopter one's.

Try obtaining a copy of Stan Dzik's Helicopter Design and Data Book. The EAA used to sell it, though I'm not positive that it's still in print. It includes cross-sections of various helo blade designs, including a few wooden and wood-with-metal ones.

Thanks Doug!

May be some ideas!

Say, these blades look real good,looks like using a very good grade of plywood, and covering them with? either aluminun/fiberglass? but where can I get some more info on these?

Scroll down this very interesting page!

Why use wooden blades ??? :confused:
Isn't this travelling back in time ?

Wood blades have some nice features, but also some disadvantages - I knew a lot of Bell 47 operators that preferred them because there was no life limit on them, they were based on condition. But they were harder to track & balance, they'd change slightly with different humidity. They also didn't like to be stored outside for the same reason - they could be damaged from too much moisture exposure.

On Bell 47's they were lighter then the metal blades, was noticable when doing touchdown auto's - less rotor inertia. It's all relative though, they still had far more than a Robinson R22 or Hughes 300 :)

The reason for my questioning of wooden rotorblade construction is purely educational. I love to learn and wooden rotorblades were around along time. My back ground is 20 years army aviation starting out in UH-1H's in 79 and finishing off my career in Ch-47's. I truely love helicopters and studying rotorblade construction I find very interesting and it is one of the things you really can not find alot of information on. Control systems and head evolution....tons of pics and history there to read. When it comes to rotorblades there is hardly any info out there at all. Just a few cut away views and little one liner's.
