Power off autorotation with the Bell 47

[@mattrika4874]

Was shown one in 1975 by a Bristow Instructor at Army Air Corps Middle Wallop. After an expert landing, he then lifted to the 5' hover and moved about 10 yards to the left and re-landed to demonstrate the enormous amount of inertia in the rotor head (Agusta Bell 47 G4) - brilliant!

[@oliverreno4734]

Amazing!

[@Callsign_Chandler]

Fantastic stuff! Lots of cool stuff happened at middle wallop. 😎🚁

[@jockellis]

I have almost always wanted one after wedding int take off in downtown Atlanta when k was about 10. It came up no more than 50 feet from me as I sat at a window on the 7th floor.

[@RC-Heli835]

One of these used to fly by the house when I was a kid. When I heard it coming I always ran out of the house with all my might to see it. Nice auto!

[@Justwantahover]

The first chopper I seen when I was kid. Seen one a few times close up, back then.

Super job on the touch-down, great vid..

[@flyerh]

Did my autos in a bell 47 G2 with wooden blades.Didnt realise how easy run on autos were until I flew a 3B1 with metal blades.

[@zzodr9347]

Nicely done.

[@HeliPadUSA]

Great execution and filming!

[@truckerray7533]

Very nice auto performed there. Well done!

[@ThemBlinkingLights]

I trained on a Bell 47G. My instructor did not believe in power recovery type autorotation practice, other then learning how to do them. We did autorotations to the ground, like this. I like the 47, it makes a good trainer. If any helicopter could be considered forgiving, the 47 is.

[@leshenderson571]

I have been in the 47g doing this

[@dwightdodd3734]

Yeah,power recovery is a lot more forgiving......lets hear one with the motor off............

[@shanelodge391]

I never understood why you would keep on teaching autorotations with power recovery. I would always teach students a full touchdown auto.

[@lorenzodunn3226]

Excellent film footage.

[@badcompany-w6s]

Excellent flying!

[@moriver3857]

Dell done. That extra forwad speed after flaring is the key. Hice bird.

[@coriscotupi]

Love the Bell 47 sound, brings back many good memories. I had a few hours of instruction one of those in the 70s, but went on to flying airplanes instead. Too bad I didn't have the $$$ to do both.

[@frtdog]

Nice job. Had to learn how to do those in Army Helo school in the Hiller OH-23 and the Bell Huey.

[@RC-Heli835]

Super smooth!

[@endwood]

Nicely executed there:-)

[@What_If_We_Tried]

Wow, that was smooth...

Very nicely done

[@shademe]

beautiful

[@bobs1345]

I witnessed a failed demonstration of an all power off auto-rotation on one of these helicopters. It was at an air show that was held at the Greene County airport near Waynesburg Pa. The aircraft landed very hard. The tail rotor flew off and traveled up in the air and landed about 50 yards in front of the aircraft where it ended up stuck in the ground. I believe the pilot walked away. This was back in the late 1950's or early 1960's.

[@ryanhruska6667]

Beautiful job 👍👍

[@savagecub]

Seems like we used to do an average of at least two of these per day while going thru “Mother” Rucker.

[@ChrisM541]

?Is the point of this that the engine is stopped at the top of the climb, the helicopter starts to fall and blades pick up speed until close to the ground, where the pilot performs a flare - converting some of that downward speed into a brake/upward speed? If yes, why were the blades still rotating at full speed at the top of the climb and downwards?

[@stealhty1]

Good job

[@SanjanaRanasingha]

How do they manufacture the glass bowl on top? The glass screen shield? Any footage of the manufacturing process?

[@WhiteHawk77]

Not footage but this guy mentions it at 10:15 kzbin.info/www/bejne/sKOrZKWLbdF_abM

[@Pork-Chopper]

They use large molds... Like fiberglass molds, but larger...

[@Richard-zc1cj]

@@Pork-Chopper is it plexiglass or something similar?

[@Pork-Chopper]

@@Richard-zc1cj It's an acrylic, a polycarbonate. It's called Lexan.

[@Justwantahover]

They are so BIG!

[@MUSTBUYRIGHT]

Wow so if you ever lose power when your 10 feet high you can auto rotate all the way down.

[@petermcmail2691]

Very soft landing.

[@AllanEvansOfficial]

at 0:55 isn't that a major risk for negative g pushover?

[@Intrepid175a]

Not really, he was at a near hover condition, the power is cut, the collective lowered to start the descent and the nose lowered to gain the required airspeed. He may have been under 1G for a second or so as they started the descent, but never came close to a negative G situation.

[@fatoseconhecimentos7038]

-Caraca, vc sabe a sensação de ver um desses, na minha infância invadia um galpão aqui em nova iguaçu, RJ para ver ele ligado, mas saia correndo devido cachorros no local. que emoção!! -Caraca, you know the feeling of seeing one of these, in my childhood would invade a shed here in nova iguaçu, RJ to see him on, but run due dogs in place. how exciting!!

[@philkearny5587]

My first rotary wing flight was in a 47. Then Vietnam happened....

[@alexabadi7458]

Did they cut the engine or just keep it at idle ?

[@andresostep]

Chuck Kirkpatrick what if the engine dies in a midle of a flight?

[@chuckkirkpatrick6712]

You're fucked.

[@chuckkirkpatrick6712]

Mr. Hillberg, have you performed an autorotation to touchdown with the engine completely shut down (fuel cut off, ignition off, no available power)?

[@chuckkirkpatrick6712]

Sad to think that a pilot - an obviously (self-proclaimed) experienced one - would resort to that kind of vitriolic language. Any respect I may have had for you is lost.

[@chuckkirkpatrick6712]

Sorry 'berg...I was responding to Andresostep's question, not throwing an insult at you. Seems your skin is a bit thin, sir...

[@waynejones3428]

Nice auto! 🚁💨 😵

[@UTubeGlennAR]

Isn't Bell noted for the highest inertia/kinetic energy rotor systems manufactured in the USA? Suspect most of the 50+ thousand viewers of this vid are not aware how the above relates to a 100% successful full down auto I believe.

[@ThemBlinkingLights]

Training, like in the video, is what makes successful autorotations. The inertia gives the pilot more time to respond.

[@chuckkirkpatrick6712]

I'd bet the Huey is highest in that rating...

[@odderanswer]

I wouldn't be surprised. Those main blades weigh a ton. I've seen an experienced Bell 47 pilot carry out a minimum throttle autorotation and then lift off and fly another 100mtrs at a height of about 2 metres.

[@wilber504]

original OH-13 blades were wood. OH-58 first with high interia rotor blades.

[@shickenchits8123]

These make me think of MASH.

[@roughneckwolf]

He certainly didn't M*A*S*H* it down. Ha.
