An absolute engineering marvel

What is going to happen if the sprag clutch/bearing starts wearing out? Thanks

We repair the nozzle shields and combustion liners for C20 and C30. We replace all the parts; deflector, dome, inner band, outer band, saddle tangs, and one boss to call it a repair. We can replace the Hast X with Haynes 230 with our repair. We do the same with the combustion liners. We keep one part like the fuel nozzle or swirler. We built up the nozzle and swirler with weld and CNC to specifications. As good as new and less expensive.

👏👏👏

Awesome! This is the best explanation I’ve seen of how and why a constant speed prop on RUclips.

Magnificient.... Thank you.

I am looking for a used pair of 24' skywheels rotor blades for an aircomand 447 gyrocopter. Can anyone point me in the right direction?

In Viet Nam we did extensive rebuild's.Although the engine man I would rig all the control's people don't realize how hard it is.

V.N. jan.70 we had the experimental huey C mod.come in from Bell at the605th. With Bell engineers.dual hyd.H.D.cobra head,masive rotors and canted tail boom.Flight tested it in country.

We called that one part a sombrero. Obvious

For gyrocopter blade chord is matter? For gyrobee having 210mm chord and 11ft long blade(per blade) but I have 178mm chord and 12.2ft long (per blade) is it ok to use ? Or chord and all to be match?

it's crazy these little gears are handling 500+ shaft horsepower.

Thank you so much for your great video, it helped me a lot in understanding details about rotors

If one engine on a twin-engine plane stalls and the prop fails to feather, will the plane crash ?

What is the maintenance required to the transmission when an overtorque has happened?

you look like a wojak lmao

Great real-world shot of a complex theory. However how does an engine spinning at 5000rpm engage a rotor that's at standstill and start it spinning up without shredding something?

Great .....All The Best For YOU

Where is the vertical thrust bearing located and is there just one?

best explanation

Fix It Again Tony!!!

Awesome video, it helped me alot. Thanks!!!

As an Aircraft mechanic back in the 90's I worked with a helicopter crew chief who was in Vietnam, he said in comparison they had very little trouble with the wooden rotor blades of the Bell 47

Cool to see. FYI (unless I missed it)... the feathered position is generally the default for multiengines. For a single engine, the default position is the opposite for max power.

Whoever has videoed this should have shown the complete view instead of panning up and down. Good explanation, poor videography

I had a sprag unit fail on a large radio control helicopter in flight, the engine rpm went through the roof but rotor rpm was dropping quickly, I still managed to pull off one of my greatest autorotations of all time. 😀🇦🇺

...that's so cool! thanks for sharing :)

What happens if the transmission fails? Will the rotors continue to spin because to the free wheeling unit? Can you still auto?

Great!!!

"Flaps as a whole unit" means that it teeters.

Thank you

Just found this video. So....why do all modern gyrocopters use only a 2 blade, large diameter flappy rotor? I would think a smaller diameter 3 blade rotor would be less drag, less stick shake, and less retreating blade factor. I think autogyros are great except for how slow they are. If you really want to GO SOMEWHERE, rather than just fly around at 70kts, you need a machine that can cruise at....maybe 120kts. Why so slow. Do you know?

I love the design always have… So for that reason I've always flown radio controlled helicopters at the moment but the newest one is fully articulated. Most are. But the people that came together to invent all of these things made something really remarkable

I like that balanced head. So even number of blades it is. No droop. As RPM increases, allow for more flapping. What if you actually want to roll or pitch the helicopter? Maybe we need a second swashplate to govern the flapping. Maybe gyro forces absolutely dominate and the fuselage only needs a small torque.. or it just dangles like cargo on a rope.

Are you sure reduction to 390 RPM?

very nice!!!

Brilliant video. Thank you.

question, the AStar spin at approx 390 you said, others spin/operate at more like 245, thats a significant different, for a rotor system, be interesting to hear, understand how a rotor system is designed to gravitate to the one or other end of that rpm range.. can't recall which heli the other was other than it's also a 3 blade design,

This is the airbus h125 gearbox I had to join the 144m monthly overhaul project at last year...

I used to bake buns for Norm. He also went on a search mission for my Dad in cousin in Bisco! Heck of a man!

Fascinating

surprising that it grips a smooth shaft, that it doesn't have the same number of indents. it should also be possible to design it such that when reversing that it lifts the contacts completely so there is no wear when freewheeling.
