Need info on building helicoptor blades for an ultralight

[AWDlaserRS]

Does anyone have any info on how to build helicoptor rotors? Last night i thought of a new and very simple way to build an ultralight helicoptor, basically a very simple engine configuration that Im surprised knowone has thought of before. problem is I dont know how to build rotor blades, any info would be appreciated.

Carbon Fiber, or some kind of kevlar and Carbon fiber blend. ALTHOUGH i know your going to have a hella time MAKING them, if not impossible. Those Propelers on planes are 10K plus, even the old Wood ones are hella expensive. heres a little info Tid Bit, most of the power comes from the Tips of the Propelers. also. Theres a point when the propeler is at witch ur not moving air, itle just be cutting thru it.

Don't forget the ever-important balancing factor. 10k RPM and CF could be splintering everywhere. And in an open-cockpit ultralight that would be ugly.

The only way you can make home made Helicopter rotors is if they are made out of fiberglass. People have done it, and yes it will be hard but its alot cheaper than spending $1500 for a set of new rotors. Also helicopter rotors dont spin anywhere near 10k RPM, Im not sure of the average # but I think its usually around 1-2k rpms on an ultralight.

Good god, why would you ask this bunch of shop rats about aviation? Give the EAA a try, and see what a search at landings.com comes up with.

I asked here because a lot of people on these boards are jacks of all trades like myself, and I figured someone else might know something about building Ultralight Helcopters. Ill try the site you posted.

To be realistic...10k is a penny in the pocket....a C-130 prop is either 300,000 or 700,000 I cant remember....I think its 300,000 thought cause an engine overhaul is 700,000

adn as far as Carbon fiber/kevlar blades

they tried it on the jc-130s,

They tried them on these new variants of the regular C-130, as soon as an object touched them, instead of dingin or chipin like the aluminum blades on the normal 130s, they would str8 up shatter...bad news...guess what they are using now.....yeah not carbon fiber hehe

I was thinking the same thing rofl.

Anyone who has been watching F1 lately, knows that the moment CF is impacted, it is obliterated.
