Are there any civilian twin rotors out there?

I'm curious why it seems the only twin rotor around is the Chinook. Are there civilian applications with this type of design? What's the helicopter in this image?
FZ_Milkshake@reddit
Kaman K-Max for logging and a few Ka-27 derivatives I think.
Fonzie1225@reddit
Ka-51 civilian models when?
centexAwesome@reddit
Look up Wolf Creek's instagram. Seems like they have some videos of them hauling towers up a mountain. Also Kaman has a page. I would give links but I was recently purged from IG.

Possibly when Egypt retires theirs, which have significantly better electronics, armor and landing gear. Because at this rate all the Russian examples will never retire, at least not in one piece, Putin can’t afford that and he doesn’t have the rubles to replace them with with something else

Ask the Ukrainians they got one on storage that needs some love and care and it's good as new.

Did a lift with a twin rotor helicopter on 18 story cooling tower. The job was in Balt. Md and helicopter came out of Chicago. He flew out. Did lift. Took his off stick time at local airport and went home. They were better than local cranes.

Coulson has some.

HokieAero@reddit
The "civilian" Chinook is actually the Boeing 234. And there are a bunch of mil surplus CH-47Ds flying in FAA restricted category. And a few CH-46Es (the military version of the Boeing-Vertol V107-II).
p.s. the H-60 Blackhawks aren't multi-rotor but there are a ton of various H-60 models being sold by the U.S. Army (800+) and Air Force.

CHI Construction Helicopters
Eggplantappleoplis@reddit
They hold almost as much as the 737's used for firefighting in Australia from my memory.
ginji@reddit
NSW RFS has the 737 - it's operated by Coulson. Holds 15,142 litres of retardant.
They also have a CH-47 - (again operated by Coulson, not sure if it's owned or leased by RFS). Has had a recent upgrade from a 10,000 litre bucket to a 11,000 litre belly tank.
So about two thirds of the 737 which is pretty impressive.
SeaManaenamah@reddit
They had a couple of these based out of Bagram back around 2013. I remember they referred to them as Cain and Abel.

It does in my book except that it's now called the Leonardo Helicopters AW609
Major-Ad148@reddit
Is is? I had no idea. What does the AW stand for now?
Starlifter40612@reddit
Agusta Westland as you stated. Leonardo kept the AW prefix for branding and legacy reasons I'm guessing. This is the company background (from Wiki).
AgustaWestland was an Anglo-Italian helicopter design and manufacturing company,^([2]) which was a wholly owned subsidiary of Finmeccanica (now known as Leonardo).^([3]) It was formed in July 2000 as an Anglo-Italian^([4]) multinational company, when Finmeccanica and GKN merged their respective helicopter subsidiaries (Agusta and Westland Helicopters) to form AgustaWestland,^([5]) with each holding a 50% share. Finmeccanica acquired GKN's stake in AgustaWestland in 2004.
In 2016, AgustaWestland was merged into Leonardo S.p.A. (formerly Finmeccanica), where it became the company's helicopters division under the Leonardo Helicopters brand.^([6])^([7])

Not the same airframe, S-61L is a civilian Sea King.

The civilian See Kings had a bad reputation it seems. The ones operated by Disney both crashed in 1968, killing 44 people.
clockworkpeon@reddit
this incident led to NYC banning helipads on top of buildings and helicopter traffic over Manhattan itself is heavily restricted. so now helicopter traffic goes thru a few different heliports built on piers around the city. it's kinda funny cuz there are helitour companies but they just fly around the island and you don't really see much you couldn't see on a $3 ferry or the $60 ticket to go to the observatory of a tall building. maybe it's a cool experience idk.
anyway the interesting thing about this incident is: it was now defunct helicopter airline New York Airways landing on now defunct airline Pan Am's building, aptly named the Pan Am building. now it's the MetLife building. pretty neat building, it's got sky lobbies in two different sections where they used to throw swanky parties. nowadays they're not used so much due to a general fear of people unaliving themselves from the balcony (or drunk people falling off). wouldn't be a good look for an insurance company.
kegman83@reddit
Its funny because other cities also followed suit. It used to be a requirement that ALL Los Angeles skyscrapers came equipped with functional helipads. The idea being that it would ease rescue in case of a fire or earthquake. After NYC banned their use, LA followed suit. Funny enough though, the requirement for helipads for buildings over a certain height still exists. So if you look at a map of Downtown LA, you'll see that every building built after the 1950s have huge helipads marked on them.
FingerTheCat@reddit
I read this in a New York Accent and it works
Tac50Company@reddit
Interestingly enough this incident led to a ban on building takeoff and landings in Manhattan in 1977 which still stands to today. Its why all the helicopters in the city take off and land from the piers surrounding the island instead.

BonquiquiShiquavius@reddit
That was only the last straw. The helipad was controversial from the beginning due to the noise concerns. It only managed to operate for a little over 2 years before being cancelled for 10 years. It had only just started up again at the time of the accident and the accident was final nail in the coffin.
So I wouldn't say the accident was the reason. The real reason is rich people don't like to have helicopters constantly rattling their windows.

That was not the only rooftop helicopter crash in NYC.
mowing@reddit
I was visiting NYC grad schools and rode that JFK/PanAm helicopter two days before the accident. The rooftop pad was above a swanky cocktail lounge, with a staircase up to the roof.
DakkarNemo@reddit
Here is more on the accident: https://gothamist.com/news/in-1977-five-were-killed-in-helicopter-accident-atop-midtowns-pan-am-building
Here is a much better picture of the Sikorsky S-61 on the roof of the PANAM building: https://exhibits.panam.digital/great-expectations/pan-am-building/a-reality-at-last/assets/mVRaezm0eK/ok-new-york-airways-helicopter-with-empire-state-bldg_-pahf-collection-2848x2351.jpg
While the accident led to the service to the PANAM building to be suspended, that was intended as a temporary suspension, which only became permanent as a result of PANAM's demise.
Meanwhile, commercial helicopter service to Manhattan continued after the 1977 accident. Even today you can get from JFK to Manhattan on a commercial helicopter flight (starting at $195): https://www.blade.com/p/jfk
Here is an AI generated brief on this type of transportation from JFK to Manhattan and why it struggled:
As a result, U.S. Helicopter ceased operations, and helicopter service from JFK Airport to Manhattan was discontinued. However, it’s worth noting that BLADE, a modern helicopter transportation company, has since introduced a similar service between Manhattan and JFK Airport, with prices starting at $195 per person.

It was originally designed to lift ICBMs for rapid deployment, with the side effect of being huge enough to carry a lot of people. That thing is one of the wildest aircraft designs ever flown, and the engineering required for it to even be controllable is really interesting.

Vancouver Island Helicopters uses several Ka-32s for heli logging and fire fighting. They had an interesting news article about the difficulty of translating the service manuals from Russian to English

Not operating anymore now sadly due to sanctions. But they were an amazing machine for logging, beat everything out there
Lost_Beautiful_8398@reddit
Makes sense, that’s a shame though. I watched one on a fire in the north a few years ago and it was incredible how fast their turnarounds were and how much water they could fly.

Yea it is a shame, they are a pretty amazing machine and anyone that got to witness them truly saw some spectacular!

These used to take oil workers out from Aberdeen in Scotland to the rigs in the North sea.
Furaskjoldr@reddit
British International Helicopters (part of British airways) used to use them. Mainly for commercial flights to oil rigs and stuff. One of them crashed back in the 80s when a transmission malfunction caused the rotors to collide and I'm pretty sure it was the deadliest helicopter crash in history

The Vertol 107, aka the CH-46 Sea Knight with seats and windows is the one in the picture.
New York Airways even ran piston powered Piasekis for a bit.
Kaman's K Max is a single seat longline machine also built for civilian use, intermeshing rotors side by side from the same transmission.
Freddan_81@reddit
In Sweden a Kawasaki Vertol 107, or Hkp 4 (Helicopter 4) as it was called in Swedish service, took to the skies again just a few days ago, now as a veteran on the civil registry as SE-JLY. This makes ’Yngve 70’ as this individual is called, the only airworthy Vertol 107 in Europe.

Particular_Ticket_20@reddit
I worked up there in the early 2000s. The pad and the flight control room were still there. I think in the photo the pad is on the right. It was a heavily reinforced bump in the roof with thick windows for 360 visibility. It had oddball stuff stored in it.
Most of the roof had telecom and satellite antennas by that point. Interesting to read it was a fancy lounge at one point. It was storage, telecom, and mechanicals when I had access.
Great views.

wilsonianuk@reddit
What about intermeshing-rotor helicopters?
TheCrewChicks@reddit
In your mind, what's the difference between what you call an intermeshing rotor helicopter and the Chinook?
ZZ9ZA@reddit
Tandem rotor can’t collide. Intermeshed is timed so the blades of the two rotors pass through the same air.
TheCrewChicks@reddit
Chinook blades absolutely can collide with each other. Granted, other things need to go wrong in order for that to happen, but it is totally possible.
wilsonianuk@reddit
I was trying to be a smart arse by bring these up rather than what the OP was implying with the front and rear tandem rotor style.
domsylvester@reddit
I’m assuming they’re talking about more of a K-Max type setup
JJohnston015@reddit
New York Airways operated the Boeing Vertol V-21/Piasecki H-21 and the Boeing Vertol 107-II. Clint Eastwood rode on one in "Coogan's Bluff". The one in the image might even be the 107-II.
boggle-coach@reddit
Saw billings, PJ and Columbia already mentioned. Throwing ROTAK in as well, they operate a few K-Max and a converted CH-47D for a lot of powerline assembly work.

Helicopters landing on buildings in Manhattan ended because of that building.

The Kaman K Max is an interesting one and apparently the US Marines are trialling a couple but no idea for what mission. I've only just realised that Kaman's first helicopter (with intermeshing rotors) was produced in 1947.

Kmax drone, used to fly munitions to forward operating bases apparently. Very interesting articles about the challenges of drone flight. Kaman built its first drone in the 50s, there is black and white video of a full size drone flying around.

Others have mentioned most of them, hoping to see the AW-609 tilt rotor join the civil fleet in the next years as well.
TaskForceCausality@reddit
A surplus CH-46/ Vertol 107 operated by New York Airways. Basically it was helicopter air service from NYC airports to downtown and back. You could book a 40 minute flight from the Pan Am JFK or LaGuardia terminals directly to downtown Manhattan via this helicopter airline.
GG14916@reddit
British Airways had 6 BV234 Chinooks, mostly to resupply North Sea oil rigs (although I believe they were used on passenger services from various London airports, too). These did get full British Airways livery.
British European Airways evaluated a single prototype Bristol Type 173. It was not chosen for large-scale production but was the subject of a small diecast Dinky toy.
Then, of course, there's the Rotodyne, which I guess is a tri-rotor or plane/helicopter hybrid but again was used for evaluation civilian flights.
Swisskommando@reddit
There’s a random Swiss chinook that does this
Cool-Acanthaceae8968@reddit
Tandem rotor? Almost every heli has twin rotors.
Yeah.. the Chinook is used in the civilian world for aerial firefighting.
And for coaxial and intermeshing rotors (also two main rotors) there’s the Kamov KA-26 (used for crop spraying and top dressing) and KA-27 (helilogging and heavy lift) and the K-Max (helilogging and fire fighting).
