main rotor morphing

[Goldy]

OK, so you're flying along at 150 knots, and now you want to pull into a hover and do some VR heavy lift. Just speed up the rotor RPM a bit, and your main rotor blade GROWS 40% in length. Now youre ready for some heavy stuff; when youre done, slow it down 100 rpm, and your main rotor shrinks back to normal length for high speed, lighter load travel..

 

This would be really cool during an auto....just expand the main rotor, gain 40% more lift, and coast.

 

Enjoy..Goldy

I had a student once who said he was working with a guy on something like this. It would definately be cool.

Not to be the pessimist, but here I go anyway, isn't it just more stuff to go wrong?!?!

Ahhh, yes. That is what makes helicopters fly...lots of stuff moving around waiting to break.

Goldy,

 

Your point is a good one but couldn't it also have the the exact opposite effect and exacerbate a low-rotor RPM scenario?

What if just one side got stuck or if one side had the spring break? That would make for an interesting landing...er.... crash.

That would give disymetry of lift a whole new meaning. I had toyed with the same idea, unfortunately centrifugal force worked opposite to the ideal configuration.
