Wikipedia copy-pasters in youtube have millions of subs but real talent is actually underappreciated on RU-vid, you don't normally get this stuff for free lol

This is the only channel where you can actually learn about canards, inlets, delta wings! Grazie per il lavoro!

F-105 had diverterless supersonic inlets, developed in the early 1950s, for its first flight in October 1955. Alexander Kartvelishvili was the chief engineer, who was born in Tbilisi, Georgia.

Your channel is simply amazing. Going in depth on topics no other channel does and well narrated. Thank you for producing this content.

great content as usual. Well done!

This channel is so good.... I subscribed just now

10:21 yes we need a retrospective on the AMX now :D

Again great clear explanation of very complex intakes, and gripping unknown history of a hero sec (family man aswell) and of aeronautical engineering to boot.

Very interesting topic: thanks for making a video on it! 🙂

Such good intro always on your videos!

Very nice to see ur production style improve

Very interesting. I keep learning stuff here.

Love your channel!

Your videos are so good that i watch the ads. Greetings from Argentina.

Also fighter jet engines comparison from 2015 till 2025 ( Current and near future platforms comparisons, energy generation in KN , Specs, Blade designs, Load capacities etc )

Never knew it has such a long and storied history and from Fascist Italy of all places!! I learn something new everyday. Fantastic history lesson, this sort of myth-busting remains invaluable to overturning existing narratives and marketing.

Very interesting subject. Thank you

L'accento mi sembrava italiano dai tuoi altri video che ho visto, ma vista la non comune proficiency linguistica avevo dei dubbi. Complimenti! Continua così, video approfonditi e originali

Outstanding

I really liked this video. Super interesting information and a fascinating tie-in to history. In my opinion the slides with text were displayed for too long, and it somewhat broke up the narrative flow of the video.

Thx for the video

This channel is amazing. Love from Bangladesh 🇧🇩

Amazing as usual.. thanks for amazing work

Wow TIL something new. Please change your tags that way you will get more exposure. This is one the best mil channel on YT

Great information and entertaining presentation! Thank you. Looking forward to binge watching in the next week. Keep safe.

What an astonishing find your work has been around my quest for lay comprehension of aeronautical development, and delightful hilarity. It is, in these distancing times, truly heartwarming to discover a new friend in science. Please accept my sincere gratitude and encouragement for your well deserved continuation.

honestly amazing ur last 2 videos are awesome compared to the really long one thank you for listening to me this video is arguably one of your most interesting recent videos because of the fact it blended so well with history Thank you very much and keep up the amazing work, also are you Swedish?? är du svensk? anledningen är din accent och du är ett stort fan av gripen. (jag alskar gripen föratt den är från mitt star linköping)

Oh Yes, please more on this Italian research agency. And congratulations on yet another outstanding video. You really woud have to do your best if you wanted to make a boring one, isn't it? You are a excellente proffesore.

Another very interesting and entertaining vid. Thanks for your efforts. Spero la pronuncia del mio Italiano è buono come il tuo in inglese! È però tuo accento Italiano è propio giusto! lol. Si … che orgoglio per un dei capolavori di Ferri. All too often in human tech history the english speaking world adjusts the discovery clock for language.

Very informative, your knowledge is phenomenal. Thanks, learnt a lot about intake design

potevo scommettere che lei era italiano , proprio dopo l'accento . Infinito rispetto e considerazione per il suo lavoro le sue conoscenze e il modo ultra coerente e divertente di presentazione. Sarebbe un sogno avere una persona come lei sulle analisi` technice della Formula 1 che seguo con uguale passione al'aeronautica.

I really enjoy your content. That being said you may need someone to execute montage for you

Lockheed Martin waited for so long not to pay any royalties.

You make great videos.... Greetings from India

Nice

Awesome video of a genius Italian inventor. Please do a video of Roberto Bartini - another great Italian that defected to Russia and became one of their chief designers. Interesting story no doubt your research and knowledge in the topic would be better.

I liked so much the explanation. I thought you came to compare F-35 jet intakes with F-105's ...

Great history until today!

Sir, how about the gap in the P51 between the radiator intake and underside, is this to avoid the effect of the boundary layer? Also, does the X32 also use DSI? Looks like it.

Could you speak to the development of wind tunnels.

Did the F105 Thunderchief not have similar intakes? In general look, they appear similar in not have diverters, although the shape is different.

Is there no maximum speed at which the diversion of boundary layer air stops working well with this design? It seems not, at least not at speeds up to mach 2.5. But I'm just curious if that approach holds up at say mach 3 or 4 or something really fast like that? For that matter, I kinda wonder if it works with hypersonic designs (plasma behaves somewhat differently than gaseous air). EDIT: I notice that the YF-23 did not have "bumps" in it's divertless design. Different approach?

May I have a question. It regarded mostly for the conventional, splitter plate solution. It splitted the slow boundary layer, this is understandable. But there is again a surface inside the intake, the velocity difference is still there, why there is not created a new boundary layer beside it?

This video was not long enough. It was cut short with just mentions of favorable constituents. I am positive books and books have been written about air intakes. On the P-51 it was thought that the air heated by the radiator scoop reduced the effect of suction at the rear of the aircraft slowing down the top speed. If this was so on the P-51, the P-47 the effect would have been even greater because of the massive frontal area. Many people did not know the same intercooler effect was under the P-47 with the intercooler for the air compressed by the turbo supercharger.

It is cool to see the different kinds of intakes. I heard that some passenger plane concepts like the Aurora use an intake that sucks in the boundary layer air for less drag on the turbofan. However, the distribution of intake pressure upon the turbofan was too unbalanced and could not be done yet. I don’t really know the technical terms, but this video has helped me learn many steps closer.

If it isn't permissible to fly at to above Mach 1.0, does it even require a DSI system.

Now, this is a video from which I really learned A LOT. So basically these DSI intakes are a further developments of the Ferry scoop intake. Which suddenly figures when the connection is made. You should have shown a picture of the XF-103 as well. It looked as if it could even scoop sugar. :-) Am I to understand that the negative leading edge of the DSI intakes actually have a negative leading edge to make part of the boundary layer bleed off to the sides? In other words. The majority of the bulge has to be in front of the intskes leading edge? There goes the inlet design of my paper STOVL project. Back to the drawing board! :-) Talking about Lockheed rewriting history: Especially US sources nowadays claim Lockheed financed the development of the Yakovlev's Yak 41 translatable exhaust when the Sowjet Union still existed! How very peculiar! I wonder if Lockheed started that story as well.

Is the F-22 style intake harder to copy?

Viva Itália. Lots more than common wisdom about pasta e vino.Great findings in many areas of science and even military history is now being "re" discovered and no, I'm not Italian but recognize value where it lies. Grazie tanta

Of course the contents on this channel you can't find anywhere on Tiktok

i love the Music. so sweet.😍♥️❤️ From Pakistan,🇵🇰🇵🇰🇵🇰🇵🇰

I sometimes wonder if you spelt 'Xi Jinping sucks' using the rivets in the next plane whether the Chinese would copy that onto their version too...

All I want to know is why the c8 zo6 didn't have enlarged stingray intakes F-15 style instead of the ugly flattened diamond shaped intakes😆.

Why doesn't the Gripen use DSI's? :)

DSI's were chosen because they are better suited to stealth, not because they are "new".

Sir are you a historian? Or in military?

Do you have a discord?

If there is a new development, chinese will definitely copy it for their own version. And if it is for a fighter aircraft, chinese ccp will definitely ask their workers to make its copy version, at-least the exterior should look alike.

Share statistics on viewership as well , I am sure you've got a bunch of Indian fans of the channel and won't be surprised if we turn out to be biggest chunk to view millennium 7 content.

So Locheed ows his family a shit load of money

A supersonic compressor can handle shocks.

However, does this cause or restrict the speed of the F35 to MACH 1.6. In fact, most jets today cannot do MACH 2.0 or better with this configuration except the Chinese/Russia design philosophy. I think the intake actually makes it more economical versus stealth or speed. Not ideal for a military jet. Or the Old US FARTS without real STEM Degree are outsourcing/offshoring to other countries...causing security vulnerability.

I finally found someone who is a little more intelligent than me 😃. Praise be to gods of Aeronautics and combat and not the gods of blind nationalism 😍🙏🙌

Ciao, come di solito video ben fatto;complimenti. Non ho visto un analisi specifica sul Su-57 anche se onestamente senza il motore definitivo e un lavoro ancora in corsa,essendo probabili cambi agli uggelli e alla presa d'aria. Vorrei soffermarmi sui inlet del SU-57. Quoto l'ingegner Aleksander Davidenko general designer "La presa d'aria del 57 e una meraviglia ingegneristica". Leggendo le fonti russe loro dicono che e variabile,trattata per la riduzione del Rcs e verra istallato il blocker...Invece guardandolo sembra che è un ibrido avendo "il bumper"...Inoltre si vedra se mettono o meno il blocker, e se questo causerà qualche problema di shock.Buona serata

The supersonic intakes are great.... except the F-35 is flight restricted and can’t go supersonic for a prolonged period without falling to f*#+ing pieces!? 🤣😂 I tried to give this turkey a chance, I really did, but that one was the last straw for me; along with putting all of our ‘eggs’ in one basket. I hope the damn thing proves me wrong and, ultimately, turns out to be the next F-18 or A-10 but I severely doubt it.

Please do a video on Ideal Indian Airforce for 2025. What to procure, which platforms matter in this terrain and neighborhood as well as pros and cons, it'll be a hit without a doubt 🙌🏽

Aircraft with DSI are slow and use subsonic engines.

I think it's spelled "divertless" for ease of spelling

While not a divertless intake, the Grumman F11F-1F Supertiger prototype that was the loser in the Lockheed F-104 bribes (it was the preferred aircraft by the German and Japanese pilots) had a bump ahead of the intake. It was a contemporary of the Crusader III. Post 16 of this thread www.secretprojects.co.uk/threads/grumman-xf11f-2-super-tiger.455/ has good photos of the bump.

Dude... you always say the stuff you talk here "are not easily found on RU-vid"... The stuff you bring is NOT EASILY FOUND! PERIOD!! ;-)

Aha! I have a model of the Aeritalia/Embraer AMX. I love that plane. It is a near-perfectly designed aircraft for ground attack, close air support and coastal defence. It does what it's supposed to do and doesn't cost an arm and a leg. As for the "F"-35.... What a terrible, overpriced and horribly-executed piece of garbage. It started its life as the Russian Yakovlev Yak-141 Freestyle which Lockheed bought. This ground-attack aircraft that the Americans call a "multi-role fighter" just to fool more countries into buying it has the second-worst level of wing-loading (after the MiG-35 but the MiG-35 has vectored thrust) and the absolute worst thrust to weight ratio of all modern fighters. It's also the slowest supersonic combat aircraft in the world with a top speed of only Mach 1.6. This means that it's a horrible air superiority fighter and an even worse interceptor. It should be called the A-35. This plane is a dog's breakfast because a (MiG-31) Foxhound would eat it for breakfast.

Hurray... India got 5 Rafael jets.... India is the strongest and mightiest..

It looks ugly

I think you mean invented by an American. 😉
