1994 clips of Chuck Beaty's gyro

[C. Beaty]

I stumbled across a couple of Utube clips of my gyro from 1994 that others have posted.

The first was shot at the PRA flyin in Greencastle, Indiana with me flying very gingerly; I was fighting 2/rev rotor shake that’s inherent with a rigid rotor pylon. I was trying a free coning rotor with the hub having a door hinge type arrangement at the hub center, no undersling and with outboard drag hinges. It didn’t work very well and the problem was finally solved with a slider mechanism.

The second clip is with Italian Pier Luigi D’Armi wringing it out at Ernie’s place in Florida. Pier Luigi didn’t speak a word of English, proving convincingly that lack of English is no detriment to yanking and banking a gyro. His sidekick, the guy playing with Ernie’s dog, was fluent in English.

Pier Luigi was a genuine character. He smoked those black, corkscrew Italian cigars that smelled like the garbage dump had caught fire.

Both clips are labeled 1994 but that doesn’t seem right. I don’t think even wild man Pier Luigi would have been flying that aggressively before the 2/rev problem had been solved.

Great footage!

I would not have recognised that as Green Castle.

Well, I missed out on still another good one. I can't view any "youtube"...:sad:

Have to save my dimes and get a better 'puter.


Cheers :)

Harry, your antique, low ball computer ought to show Utube stuff.

You need to install the Adobe flash player (there’s a link on Utube), start the video download and go out to supper or whatever. When you comeback in a couple of hours, the download should be complete.

A high ball, state of the art computer won’t make your dialup connection run any faster.

.The fact is, Tim, I don’t recognize that airport as Greencastle either. Just going by the onscreen text.

My recollection of Greencastle was that there were no trees on the far side of the runway, just cornfields. I think Mr. Kokubun might have shot that tape in Florida and been confused as to date and locations. Perhaps Wauchula, '92 or '93.

Chuck - I have not been able to find a post on one of your tests that used just the lead-lag hinges on your rotor hub (no flapping hinges). I was wondering how well it worked. It sure seemed to fly well in the video. Thank you.....

[C. Beaty]

Ed, I’ve never had a rotor with lead-lag hinges only.

I’ve had several that had no hinges at all.

The 3-blade rotor on a Bensen in the first picture had the feathering bearings at the apexes of a triangular aluminum plate which was in turn attached to the rotorhead by 3 rubber bushings (Chevy engine mounts).

The second picture used a similar arrangement with the hub made from filament wound fiberglass with it being connected to the rotorhead by rubber bushings.

The intent being, that if the hub could be permitted to align itself with the rotor tip plane axis, there is no special need for either flap or lead-lab hinges.

There are or were some film clips of both flying that were posted by someone in France but I don’t know where.

I stand corrected. Your no-hinge ideas sure seem to make alot of sense. I can't help but wonder how well these ideas worked.....and how in heck did you arrange the rubber bushings to take the blade CF loads without using some kind of pivot bearing? It seems to me the rubber would have crushed if it surrounded a pivot attach bolt. Man, I wish you had all your experiment stuff in a book.

[Harry_S.]

Chuck, my low baller only has 64 whatchacallits and I need 128 to hook up my HP Photosmart. That's why I want a newer model.

With a newer model, I'll go with a new ISP, cable or telephone?!

Meanwhile, I'll try your suggestion with the Flash Point / Flash Player?!

Another reason to upgrade. I just clicked on utube and the all too familiar window freezes my on line and shuts me down...Wcs 2000 and states, "This is an illegal operation and will be shut down." What gives with this??


Cheers :)

[C. Beaty]

I dunno, Harry, one of the genuine computer experts here probably knows why.

If its 128k of memory you need, I'll be happy to give you a stick. I have some of that stuff lying around (PC66/133) that I’ll never use.

It seems to me the rubber would have crushed if it surrounded a pivot attach bolt. Man, I wish you had all your experiment stuff in a book.Ed, the three blades were tied together on a common hub. Each blade was connected to the hub by a stack of ball bearings, the feathering bearings. They accommodated cyclic pitch and had to withstand centrifugal force.

The hub was connected to the rotorhead by rubber bushings. They had to support the weight of the machine.

Here’s a photo of the ’89 rotorhead.

[RotoPlane]

Oh, now I understand.....duh, I was thinking the rubber supported the blades. Thank you for taking the time, Chuck.

[Harry_S.]

Thanks Chuck, I appreciate the offer. I was advised I could do that some time ago, but another guru advised me that it could cause some problems with my machine. :noidea:

I'll get somethin' new with all the high speeders...eventually.


Cheers :)
