Guided tour around the ULTIMATE Hercules. The Boeing YC-14

[@staralliancefan1245]

A great video as usual. There's a few other videos on this aircraft but none include your level of detail. Thanks for not just reading the wikipedia article!

[@PaulStewartAviation]

Thanks! I do use wikipedia but also other sources too. I’m glad to hear that you appreciate the effort I put into these as they do take a long time to prepare:

I was here first patting his head. 😅🎉❤

[@newflyer6837]

I agree! Great videos!

[@MrMousekillaz]

grew up in Seattle 61- 2011 andsaw so many icons like the two YC-14's coming and going at Boeing Field (King County Internayion Airport) along with AWACS, first 747, 757, 767,777 etc... to young to remember the 07, 27 or 37 launches though, but saw plenty of them later on the flightline beside Boeings delivery center

[@PaulStewartAviation]

wow what a place to live! Admittedly, I'm very lucky to live near the HARS museum in Australia which regularly has a Super Constellation, DC3/c47s, neptunes and more flying around. In my 3-ish visits to Seattle I've been excited to see 787-10, 737-10 and 777x prototypes flying past.

[@mrmet1679]

You should check out the Air Mobility Command Museum in Dover,Delaware. There is a decent amount of aircraft and a C5 galaxy

[@PaulStewartAviation]

Yes I've recently discovered that museum but sadly when I asked about filming their C-5 I was told no. :(

[@slypear]

Great presentation, thank you! Was truly great as a kid to see one of these when it was on display at our local USAF base~ Such a freaky design at the time, for sure!

[@t.travelerjg1908]

Excellent video! I remember seeing the YC-15 parked next to the YC-14 at Pima Air Museum during the 80s and most of the 90s. Always thought it was cool that the Air Force put her back in service after such a long time sitting in the desert. I guess she was destined to be a desert dweller as she now sits broken in the CA desert.

[@davidyates8880]

I saw one fly at the Farnborough Airshow in 1976. The YC15 did a flying display as well. There was loads of hype about them at the time.

[@newflyer6837]

Farmborough airshow would have been incredible decades ago with such a diverse range of aircraft from the Soviets, Americans and Europeans. Similar to when there was such a diverse range of car makers... now they're all the same boring EVs (nice cars but no soul).

[@davidmahony4421]

Paul another great video

[@johnfalkenstine8377]

This is a very good presentation. I have been out there many times to look at this airplane, very busy at that time as engineer at the Evergreen Air Center. The plane is a real gem. Unfortunately, Pima Air Museum likes to display airplanes but does not take care of them properly. This plane deserves a better fate and should be indoors with a good presentation, especially about its engineering features.

[@PaulStewartAviation]

thanks for watching. In Pima's defence, they have a lot of aircraft and it would cost many millions to restore all of them.

Thanks Paul always enjoy your videos. I’ve seen both YC-14’s on my trips to Arizona. Interestingly, in the early 1980s, on a tour of the de Havilland Canada plant in Downsview, I saw the QSRA aircraft. Lovely.

[@fredtedstedman]

She always looked such a great performer !! Antonov is the only manufacturer to use COANDA principle these days . ( An-72.) I wondered if you would remember the 4 jet Buffalo and you did !! great video mate !

[@rocketpunchgo1]

Finally! We've been wait weeks for this video lol

[@RCAvhstape]

I feel for the engineers who put so much effort into these cool designs only to be relegated to the oddity bin of history. It's why that video of Jack Northrop being allowed to see the model of the B-2 is so powerful; the old man at the end of his life is finally vindicated when his flying wing design from decades earlier finally becomes real.

[@dtrain1634]

Awesome aircraft! I have many times pondered to do the Anigrand 1/72 kit :)

[@WhiskyCardinalWes]

I've been looking forward to this video! Pity that you weren't able to get inside to document what little remains of its interior.

[@PaulStewartAviation]

Yeh agreed about the interior. They let me inside a few other aircraft (ie b24) but I suspect that these older relics are legal hazards and full of snakes. I’d never sue (I’m an aussie!) but they don’t know that.

[@airplanedude7105]

Growing up in Tucson, I always loved seeing this plane and the YC -15 as a kid. It made me sad when they took the YC-15 and then scraped the other one at the boneyard. I had hoped that you would have been able to get inside, I heard the engines are inside. Great video though.

[@restaurantattheendofthegalaxy]

Very interesting aircraft! I wonder if the engine noise was just deafening in the cockpit? (Great video!)

[@moseshancock3336]

It would be cool to fly in one just for the excitement.

[@SnappyWasHere]

Seems like it could’ve been a cool aircraft. Lots of power and speed while still STOL. Pretty impressive.

[@paullewis5045]

Looks like the YC-14 has a Seaplane as a neighbor. Appears to be in nice shape too. Any chance that has a video in the works? I don't believe ugly sells very well even to the military. But that aircraft's true beauty may have been in the innovations which seem stellar.

[@PeterRandell-o6z]

Really enjoyed this Paul. Meanwhile, I'd love to see a video on the c-5 if there are any old ones in museums.

[@PaulStewartAviation]

Yes I’d love to film the C-5 but there’s only one on display in a museum and they said no. :(

What a great plane and vid❤

[@ericbrammer2245]

Yup, you nailed the Airflow positives, but, not the Turbulence Vortex negatives that Stopped this awesomely Able plane from being the Next C-130. It literally would 'suck-up' it's own disturbed airflow, and ingest, to it's Turbine Blades, Dirt, Rocks, and such. It did have Thrust-Reversers (like the Saab Viggen did) to slow itself down upon Landing. When Not using that Feature, it Deployed multiple Slat flaps, and These, led to particulate Ingestion in the Turbo-fan Engines, which would 'unbalance' them.

[@PaulStewartAviation]

Thanks for the extra information

[@Sacto1654]

In short, the USAF realized what they REALLY needed was a C-141 replacement. The result was the C-17 Globemaster III, which the USAF ended up buying 222 planes. I still think they may look at the C-14 again soon, especially now that the C-130 is getting a bit long in the tooth.

[@dl6519]

The engine-out asymmetric thrust condition was not nearly as dangerous as the engine-out asymmetric LIFT condition because of the extra Coanda-effect lift on the side with the surviving engine. This lift asymmetry would have been particularly severe in take-off configuration (flaps down, engines at full power). The asymmetric lift would have caused a roll towards the side of the dead engine. Whether the pilot could react correctly in time during takeoff was questionable. The ultra-high-authority segmented rudder might have been designed to give the pilot a sporting chance of recovering the aircraft in time. The forward landing gear doors remaining open helped to prevent foreign object damage to the engines from debris kicked up by the nosewheels. GREAT video!

This was one of my favorite airplanes. But the "ultimate Hercules" nowadays is called C-390.

[@jamesmiller6834]

I think there is one at Edwards AFB CA. It looks like the YC-15.

[@stevebush370]

I flew AWADS & Special Ops C-130s. Low level flight was at least part of the flight envelope for the YC-14. As a consequence the YC-14 would consume considerable fuel. Check Credible Sport performance.

[@magoid]

They spent a lot of money to modify the C-130 in a STOL configuration, for the rescue of the hostages in the US embassy during the Iranian revolution. Nobody thought they already had the YC-14/15 that would fit like a glove for that mission.

[@eddiehimself]

Another Soviet aircraft that came out with a suspiciously similar engine layout to a recently-released western model was the Ilyushin IL-62, which had the same 4 engines mounted on the tail of the aircraft as the British Vickers VC-10.

[@mirthenary]

Funny thing, was just watching the latest How Ridiculous video before, I assume you're aussie as well...

[@SPak-rt2gb]

Since you were at Pima are you going to do any videos of these interesting aircraft that were there: Columbia XJL-1 Seaplane Bud RB-1 Conestoga Northrop YC-125 Raider

[@PaulStewartAviation]

I'm afraid not. maybe next time when I'm sure to visit again :)

[@OfMoachAndMayhem]

USB flaps. In these modern days, that reads like something completely different... Makes you think of a 5V plug-and-play high lift device which requires the only single good cable you have in your home to operate, inevitably ensuring you cannot charge your phone at the same time no matter how many other cables you have. You also need to turn the plug some 3~5 times upside down before it attaches, since as we all know, those plugs exist in 4-dimensional space. I don't think that's what the designers actually meant, but reality is a lot funnier if you replace it with completely out-of-context interpretations, isn't it?

[@chrissakal532]

I saw this way back in a book about aircraft in storage at Davis-Monthan right by Pima. It looks like the YC-14 was an excellent design and would have done its mission well. I saw Pima's B-24 Liberator at the beginning of the video... any chance of a B-24 tour? I didn't see one on your channel.

The engine in your video looks very much like a RB211-22b ( has integral thrust reverser) I thought the YC-14 had a CF6

[@PaulStewartAviation]

I can't say with 100% certainty that it is a CF6, but it would be odd to position RB211s next to an engine-less YC-14. Someone else may be able to answer?

[@iansmith6962]

@@PaulStewartAviation Hi Paul I have worked on both RB211"s and CF6's so I think I know the difference.

[@PaulStewartAviation]

I spoke with an aviation mechanic friend who also said that he thought it was an RB211 too. It's unfortunate that it's placed right next to the YC-14 as it would be reasonable to assume that it's an engine from the same aircraft.

[@ronparrish6666]

Didn't they put the nose of that on the C17 or was that the DC 10

[@PlanesAndGames732]

I wonder how that would compete with the C-390

[@xyzaero]

Thera would not be a C-390, if the US upgraded to the C-15 or C-14 instead if the C-130J.

[@gtv6chuck]

I thought this was an amazing plane when I was a kid, and I was so sad when it was canceled ,and I was also pretty sad to see what it looked like when I saw it at the Pima County Air Museum. The plane was so much better than the C-130, from speed to range to payload, and the USAF logistics system is poorer for it not being in service.

[@NeroontheGoon]

Fear not, the Russians borrowed the design and build a version of it! The AN-72 “Coaler” is similar to the YC-14.

Is it even legal to post a 747 spool up but it not be an RB211?

[@davidcarter4247]

Cannot see the connection between the YC-14 and MV-22 Osprey. The Osprey relies entirely on rotors to take off and land. The engines/drive shafts are interconnected because it simply cannot fly on one rotor . The YC-14 relied on the Coanda effect for STOL performance. The sudden loss of lift would be deadly only if it was at a critical point in the flight and the YC-14 could otherwise be flown safely and land on one engine. Also I heard you use the word "flare" to describe the undercarriage compartment. These have been called fairings for as long as I can remember, which is descriptive of the fact they fair the airflow around the undercarriage legs and mechanism. These points aside it was an interesting video about an aircraft I knew little about. The concept of the YC-14 and its use of the Coanda effect proved an aviation dead-end, AN-72 aside. Not the first and will not the last great aviation idea that proved impractical in the real world. McDD's more conservative approach to the specification did end up providing it with data that was very useful in the successful C-17 even if the YC-15 went nowhere itself.

[@PaulStewartAviation]

I should have been clearer. My point was that the MV-22 has a mechanism for one engine to takeover both props therefore a single engine loss wouldn't lead to an immediate and significant loss of lift. The YC-14 had notsuch mechanism and any single engine failure on takeoff would have resulted in an immediate crash.

[@davidcarter4247]

@@PaulStewartAviation Point I was making is that the interconnected rotors were a fundamental part of the MV-22 design and permanently engaged. Each rotor is powered by two engines just like Chinook rotors. The YC-14 is no different to a Caribou in its dependence to engine driven airflow for lift at low air speed.
