I remember when the YC-14 had its first flight. Seattle knew that it would happen soon: the bird had completed its high speed taxi testing and the weather was perfect. When it was spotted on the runway at Boeing Field, much of the traffic on Interstate 5 pulled off onto the shoulder to watch (I was one of a mile long linear parking lot with a great view of the field). The first flight is relatively short, so the fuel load is minimal and the wing is lightly loaded. It used only a fraction of the runway and climbed out at a very steep angle; it was beautiful! (a retired Boeing engineer)
And another romanian Anastase Dragomir (1896-1966) was a distinguished Romanian inventor, most famous for his "catapultable cockpit" patent (with Tănase Dobrescu) as an early form of ejection seat, although preceded by Everard Calthrop's 1916 compressed air ejection seat, and others.
Soviet aviation is so interesting, because its design is quite different. Information is so rare, there is always a plane nobody knows, making it even more mysterious and fascinating!
Undoubtedly great designs, virtually handbuilt & with no economies of scale = tiny fleets with spare parts and training issues. The engines were and still are the achillies heel of soviet & RF aircraft.
@@Vladimirthetiny No economies of scale in nearly 200 aircraft in 5 years, on plants that were at capacity? How many commercial aircraft do you think are built??

The original An-72 was probably the greatest loss, as it was more or less fully developed and could have been retained as a variant. Instead of having a mediocre commercial airliner, a great STOL would have been really good and filled the niche better.
Definitely a damned interesting aircraft with some even more interesting special applications and modifications. I really like the aircraft that were made to fill small niches like the An-72, DHC7 and DHC-6. You should do a video on the DHC-7.
The Americans _almost_ got there first with the Boeing YC-14, which was going to into production to replace the C-130 by 1980. But the USAF in 1978 re-assessed its transport needs and found out what they _really_ needed was a replacement for the overworked C-141. The result: the C-17 _Globemaster III_ , which the USAF ended up buying 222 planes.

@rustyjeep2469 Yeah I am no fan of the lefty social justice crap pushed for so long but I'm afraid of the pendulum swinging too far the other way. There have been quite a few women who were integral to major flight projects and discoveries.
You didn't mention that the Russians plan to suppliment the Il-112V by replacing the turboprops with PD-8 jet engines and the plan is to mount said jet engines above the wing similar to the arrangement on the An-72. Eventually the engines for the Il-112V will allow a turboprop version, but the Il-212 version could replace the An-72s in service while the Il-112V will replace the other lighter propeller driven Antonovs. I also wonder if experience of putting the engines above the wings on the Il-212 might lead to them doing the same with the Il-276 as that would reduce the risk of FOD too for rough field operations.
When I lived in Vietnam I remember seeing two An-72s on the ramp in Saigon. I don’t think they were Vietnamese military but there were several Russian oil companies down in the area. Very unique airplane to see when taxiing by.
Vietnam didn't operate an72 and I haven't seen it , wonder which year you see it ? And yup the Soviet have a join venture with Vietnam for oil exploration in SCS ( later the Russian replace Soviet ) fun fact only Russian dare to drill oil with Vietnam in SCS , Spanish and american company all Fleed once the Chinese put pressure
@@ATLOffroad probably just a visit , an74 are super rare , an124 and il76 are hella more common as they transport cargo and stuff from time to time into Vietnam
I originally thought the engines were up high over the wing, so they didn't have to worry about them ingesting any Debrie from runway, I see it is only an added bonus and thank you for sharing videos. I love airplanes.
Such a neat aircraft. Go anywhere machine. Watched videos of it doing polar flights to Barneo Base landing on snow pack. Very nicely done short documentary.
Planes like An-72 with engines installed above the wings are uniquely nuanced of its kind. The Coanda effect helps increase lift force of the wings in turn reduces takeoff distance
@Darren_Xero; The YC-14 from Boeing had this engine placement, some decades ago, and it had excellent STOL capability, but was taken out by USA politics...
Henri Coandă’s contributions didn’t stop with the jet engine concept; his name lives on in the Coandă effect, which remains fundamental to both science and engineering today. Truly a visionary ahead of his time!
Thanks for a really enlightening video! I didn't realize that liquid running down a vessel instead of simply pouring was due to the Coanda Effect. As an American, I had dismissed the An-72 as a cheap copy of the YC-14. Obviously, it was far more successful and it's sad that it didn't achieve even more success. Thanks again!
Great video sir. I have always loved the AH-72. Over the years I've heard of a variant the 76 as a board patrol aircraft with rearward facing guns mounted in the wings and sold to Iran?. Thank you for your video.
This is another great video about another strange Soviet plane. Keep'em coming. BTW: I'm interested in some jet powered passenger float planes. They had the same high mounted engines & a distinctly Soviet look.
Why not go for a low wing configuration when the engines are on top of the wing? This would save structural reinforcement for the high wing and therefore weight.

It's not just unexpected lift changes which can occur from an engine arrangement like this, but also moment (torque). So in some ways it's probably good that the Coanda effect was minimal in the production versions... though as noted the design ends up being closer in specs to ordinary though still saddled with harder to service engines.
Excellent Coanda examples. I actually never realised it also literaly applies to fluids. I would simply have called that adhesion. But that is after all what the Coanda effects is also about, isn’t it?
Air is sticky, the simplest explanation of the Coanda effect, a phrase that caused one of my instructors to roundly insult me. When a fluid is moving, say air, it sticks to a surface in its movement. And this one aspect of the Coanda effect makes for more interesting Coanda ducts, of which there are many kinds, including one duct that will reverse itself. If a Coanda duct is used for grit blasting, not only does it do a better job than a simple nozzle, but eats ceramic like crazy. I couldn't get one crafted of tungsten carbide, which would have lasted a lot longer. Boss told me to scrap the nozzle because it was a waste. Sure blasted pretty good, though, but went through grit like crazy, it blasted so much. Too bad this would have been the C14, had Boeing gotten the contract. The Soviets couldn't've afforded to design this and build the proof of concept and prototype, but after Boeing worked most of the kinks of concept and design, and I can't say more than that because everyone is gonna think I'm saying bad things about Soviet acquisition of useful information. Regardless of how design data for the Coaler, Antonov did a pretty good job on this, and helped explain why the USAF didn't want it. But the Soviets kept it and continued developing it.
Seattle’s museum of flight might have the American version sitting outside with other large aircrafts. American military didn’t think there were no benefits building a small transport plane. But I could be wrong. President Carter cur many projects…
They decided anything that couldn't be done with helicopters could be done with C-130s, an anything that couldn't be done by them could be done by C-17s. etc. etc. up to C-5s.
Okay I know this isn't the point of the video but does anyone else have a kettle that only shuts off when boiling when the lid is down if you leave the lid open does it continue boiling

Another advantage of having the engines so high up, is you can operate from remote unprepared airstrips with less risk of FOD’ing the engines.
