A VERY LIGHT ALL ALUMINUM ROTORBLADE

A VERY LIGHT ALL ALUMINUM ROTORBLADE

A VERY LIGHT ALL ALUMINUM ROTORBLADE

(OP)
For experimental purposes I want to build a rotorblade that is as light
as possible for the purpose of being able to pick up 200 pounds. My
plan is to build a blade (I built one a few years ago out of steel
(welded)) out of aluminum. I plan to cut the airfoil shape
(asymmetrical) from aluminum sheet of perhaps .050 thickness and
saw notches into them to which aluminum stringers could be glued.
The finished rotor would then be covered with cloth and a
windprofing coating applied. I am thinking of a 20 foot rotor.
    It would be interesting to hear from professionals and others
the yeas and neighs of such an undertaking.

RE: A VERY LIGHT ALL ALUMINUM ROTORBLADE

Keep it lite. ribs of .050 too heavy look at early Sikorsky blade construction,chech out Igors history.
