People ask: Why does it sound like a Huey? Interesting question! A lot of what you hear is tail rotor growl. The UH-1 and S-55 tail rotors are about the same size and turn at about the same rpm, producing a similar noise. As for the main rotor... The UH-1 rotor turns at around 324 rpm. But it has two blades, so two-per-revolution means that you hear a blade 648 times per minute. The S-55 rotor turns at 220 rpm. But it has **three** blades, so you're hearing 660 blades pass by for every one revolution. The aural difference is quite small. And so the S-55 sounds like a Huey. For comparison, the Bell 206 main rotor turns a frenetic 394 rpm, meaning that you hear 788 blades per revolution! You would never mistake an S-55 for a 206. Oh, and the exhaust is angled up to make it quieter. The conversion to "Whisperjet" configuration (5-blades and the muffled exhaust) was designed to make the ship less noticeable to people on the ground. Turbine engines can be quite annoying. A standard (i.e. non-Whisperjet) turbine conversion of the S-55 has an unmuffled exhaust that comes out the front of the engine cowling. When it's nearby, it is just as loud as the piston version, but with an unpleasant high-pitched whine replacing the arguably more acceptable low-pitch roar of the radial engine.
some are in service for passeger, utility or used for drying cherry trees as some in service are either in its original piston engine form or the turbine conversion models the military it was configured in many ways ans was called the H-19 as the Sikorsky company # is S-55 which then Sikorsky was part of the United Aircraft Corporation later United Technologies as it was loosing money under United as Sikorsky as it is now is owned by Lockeed-Martin
It belongs to Pirate Airlift based at the Jackson County Airport, Jefferson, GA. I talked to the owner/pilot when they were doing a job near me. It is a complete rebuild after it crashed in 2002. It was previously used to fly tourists over the Grand Canyon. That's why it has those large windows in the doors. It has had many owner/operators over the years, even on display at a Canadian museum for a while. Originally delivered to the USAF as an H-19B Chickasaw (53-4414).
Thank you. Your background knowledge is spot-on! It was Papillon Helicopters that operated this aircraft, out of Las Vegas on Grand Canyon flights. I think it may have been re-engined with a Garrett AiResearch turbine. In 2004, I was in Las Vegas and enquired about flying in this type, but it had been discontinued. Instead, I flew with Maverick Helicopters, in an EC130, which was a fabulous experience.
it was once a Papillon Grand Canyon Helicopters as this was a S-55 QT quiet technology as you can see the noise cancelling bafflle on the exhaust on the engine as it has a 3 blade rotor instead of a 5 blade rotor it had as before that it was once powered by a radial piston engine before it was converted to turbine. Kermit Weeks has one of these was a s-55QT same large windows in the doors its in storage missing the rotorhead, the engine and nose doors as he is converting it back to a radial engine a Pratt& Whitney Wasp R-1340-57 from the other airframe he aquired part of a deal when he got them in Reno Nevada is 2018as his plan for that helicopter and another one he has is for a ride operation. as only 5 S-55 were converted to the S-55QT Quiet Technology were operated by Whisper Jet then for Papillon Grand Canyon Helicopters as then were noise complaints from the Bell 206 Jetranger helicopters they had the hikers complaining of their noise and thats why they converted a Korean era S-55 or H-19 Chickasaw to a quiet transport.
This is very interesting! It almost reminds me of the sound a Bell UH-1 Huey makes. Love the sound of that tail rotor. Those early helicopters changed the world forever, especially when this came along. The s-55 as I understand had the radial engine under the nose so you could have a bigger cabin under where the rotor turns, allowing you to carry more troops.
The only real thing I'm confused over is, when I looked up the registration number on the web it pulled up a QT model, which had the 5-bladed rotor system. Based on the sound, I'm assuming this is the original 3-bladed rotor. I am blind and have always been interested in aviation so this means a lot to me.
you can hear the sound of the tailrotor easilly with the turbine engine but it would be impossible to hear with the original radial engine in them as the radial engines are louder than the turbine engines being this was a S-55QT it still has the noise cancelling baffle on the exhaust of the turbine engine. the S-55 used two kinds of radial engines a 650 Hp Pratt & Whitney Wasp R-1340-57 9 cylinder radial engine with a centrifiqual clutch which has the engine's cooling fan on it. the other engine it used was a 800 HP Wright Cyclone 7 R-1300 7 cylinder radial engine and a hydromechincal clutch which uses a clutch pump to pump fluid to the clutch during the spinup then the engine rpm is reduced below the Rotor Rpm when a sprag mechanical clutch engages and when the engine rpm is reintroduced its a 1to1 lock but all have to disconnect from the clutch when an autorotation is used. as then this was a Korean war helicopter as it was designated the H-19 or UH-19 which this is a utility helicopter which the cargo area is below the main rotor for proper weight and balance
I know where this helicopter is located as well. Some great photos of it and another on here. Good to see those old vintage helicopters back up and flying.
this was used to be used by the Army during the Korean war as it was once powered by a piston engine either by a Pratt & Whitney R-1340-57 9 cylinder Wasp radial engine rated at 600 hp as the later variants had a droop tail to give the main rotor clearance and were powered by a 700 HP Wright Cyclone 7 7 cylinder radial engine with a hydromechanical clutch. This one has been converted to turbine power was modified with a noise cancelling baffle out the right side and it would of had a 5 blade main rotor which this particular conversion was the S-55 QT having a Garrett AiResearch TPE-303 Turboshaft engine as this helicopter was one of 5 converted with the 5 blade rotor and was used for sightseeing tours in the Grand canyou as this would of been painted in the Papillon Grand Canyon Helicopter scheme as the 5 blade rotor this would of had prevented the retreating blade stall when these flew over the Grand Canyon as this helicopter does have the double doors plus the plexiglass window in the bottom for passengers to see the Grand Canyon. then again this helicopter in the video was a S-55QT but now has a 3 blade main rotor. the Military designation is the H-19 known as the Chickasaw and were made in Europe as the Westland Whirlwind some of these were in Reno Nevada in 2018 which one of the former S-55QT and another S-55 were purchased by Kermit Weeks of Fantisy of Flight in Florida as both and another S-55 he has are all in storage. as the former QT airframe at Fantisy of Flight is being turned back into a piston engine one and the one is to be a static display and they plan to have two helicopters to give ride operations around Fantisy of Flight and Orlando. there is many s-55/H-19 being used or on display.
there is other S-55s flying check the other youtube videos. this one in this video was a S-55 QT quiet technology which originally had a 5 blade main rotor and a Garrett turboshaft engine with the noise cancelling baffle which you can see on its exhaust. it was once used in the 1980s for Whisper Jet for Papillon Grand Canyon helicopters as this airframe plus another one which now Kermit Weeks owns are the two known ones as Kermit plans to convert it back to the radial engine the P&W R-1340 from the one helicopter he purchased two including the S-55QT in 2018 as he plans for the former QT airframe to be painted in Orlampa Airways and his other S-55 he has was a New York Airways helicopter thich he got 12 years ago now in the Golden hill storage facility of Fantisy of Flight. as of now all three of his S-55s are in storage. this one flying in the video is awesome to see.
After seeing this video and the other video on the S-55QT N17756 when it was in its QT form lifting items then around 2018 this QT airframe ended up in Reno Nevada was used then the 5 blade rotorhead and transmission coverings were removed when Kermit Weeks visited the area they were in and he aquired the two S-55 and were shipped to Florida to Fantisy of Flight to where there at now including one he already has which was a 1953 model formally a New York Airways S-55 which has the P&W R-1340 radial engine before he got it the helicopter which was flying out of New York to LA the pilot leaned the mixture out and it quit as the pilot did a nice autorotation and it landed in a school yard and came up to a tree and took the blade caps off the rotor which this S-55 has its original transmission coverings currently all three of his S-55s are in storage. as other S-55s are still flying some used in Oregon for drying cherry trees one owned by a private individual the ones flying are either the turbine converted S-55s or the radial engined ones mainly the ones with the Wright R-1300. after watching the videos always got to learn something new on the Sikorsky H-19 S-55 Chickasaw. as its over &0 years old and then had succeeded the S-51 hoverfly as this is the first helicopter to have the cargo loading area directly under the main rotor after they were retired from military they were ideal for carring passengers.
That originally had a radial engine, never see one with a turbine. Odd that the jet exhaust is pointed up, but I guess that's the best solution for a retrofit.
it was a S-55 QT or Quiet Technology as it has the noise cancelling baffle on the exhaust and sound dapmening equipment and it would of had a 5 blade main rotor as this was once a Papillon Grand Canyon helicopter for sightseeing tours over the Grand Canyon as the cargo hook area had a plexiglass floor for passengers to look through
Thank you for putting this video together. It’s great to see such a classic helicopter, looking so new, and flying. Do you know if it ever used to fly passengers? If so, how many seats does it have?
This S-55QT helicopter was designed by/ for Papillon Helicopters to fly tourists over the Grand Canyon, as bk1160 already mentioned. The reason it sounds different I would guess is because of the noise cancelling measurements that were built in: the idea was to have less helicopter noise in the Grand Canyon. The exhaust is muffled, and so is the engine and air intake. If you surpress the engine noise, the sound of the main rotor will be more audible. This gives the machine its indeed very distinctive sound! As a matter of fact the 55QT even had a five blade main rotor to also reduce the main rotor noise. On the ship in this clip however it looks like the original three blade main rotor remained.
this video link shows the one former S-55 T and another S-55 arriving in Florida in 2018 and shows how they put the landing gear on after they were shipped by tractor trailer the 3rd S-55 Fantisy of Flight has was a former New York Airways helicopter as what happened is when the pilot was flying it in New York he leaned the mixture out too much and it quit which the pilot made a good autorotation and it landed in a school yard and came up to a tree and took the end caps off the main rotor blades as this helicopter has a Pratt & Whitney Wasp r-1340 as this helicopter along with the former s-55 QT airframe their plan for both these helicopters is for a ride operation. the S-55 Qt in this video and the one in the video i linked were formally operated by Whisper Jet in the 80s for sight seeing tours over the grand canyon the other S-55 he got had the straight tail the later models had the droop tail to clear the rotor blades when these were used by the Navy on carriers when shutting the helicopter down they pitched around alot. As when these were retired by the military many were registered for civilian use. as one in the 1970s along with a S-58 were converted by Winnebago and called them HeliHomes which the cargo compartments were fully furnished with the ammenities of a motorhome. as there is two other videos on youtube Sikorsky S-55 Acquisition visit? parts 1 and two ua-cam.com/video/VV--D1Qleqw/v-deo.html ua-cam.com/video/MjiaTyaNIhs/v-deo.html

Yes they go later to North Carolina. Busy season a lot of new warehouse and construction jobs
I wonder what Turbine engine does it use?
Not sure

The engine is not an original one. Originally it was build with a radial 7 or 9 cylinder radialengine. This one sounds like a jetengine.

Too bad the pilot has to look thru the exhaust flow. Should fly vertical reference from the other side.
