Paul,

Do you have details on autogiro's running rotaries ? Pardon my
thoughts, but I think a rotary would work well.


Thanks,

Barron

I don't have any dwgs but Gary Buster might help you out.

Back in the days of the late Cierva and before the Advent of the
helicopter the autogyro was quite a capable machine. It had heavy two
or more bladed rotor systems which stored a great amount of energy.
Todays autogyros on the other hand in my opinion as a rated Chpl
with IFR must be the daftest thing out there. Flimsy contraptions
with energyretention on the scale of a chopstick. You would not find
my behind in One of them on a calm, stable day let alone in any kind
of turbulence. Surprises me they are legal.

Have you looked at the you tube video?

I filmed the video. Looked pretty good to me. However it was a calm
day.

IMHO the main problem is MPG.

Actually the main problem is negative G's
When that happens the disk is no longer loaded and looses momentum, which is where the lack of stored energy due to the low mass of the rotor system comes in....
the second severe problem is the underslung rotorsystem most of the nowadays ( refuse to callem modern ) autogyros employ.
It can kill You fast.
In summary stay away from them, even if a crash of one of them would have nothing to do with being powered by a Rotary engine, it would still rub off.

We are not doing outside loops here :)

There are a lot of them in the States. If the accident rate was much higher
than other experimental aircraft the FAA would be all over their
case.
