The Russian has the first twin tail jet - the Mig-25 - so you can’t say they copied that from US designs

No matter your stealthy design, you're going to be seen first when your payload is being carried under the wings. This plane screams, "I'm stealth, LOOK AT ME!"

V tails are not just to "look cool", they do have slightly better performance, the downside to them is if you lose one you will have serious flight control issues, both need to be working 100% for it to fly right, if you lose one, then both pitch and yaw will no longer respond as you'd expect, vs if you lose a pure rudder on a twin rudder plane, or one of the elevators, your plane is still going to be flyable, not so with a V tail.

Fun fact the X-32 was the only jet ever designed with a cloaca. For its part in the competition vs. the F-35, it laid one egg.

Talking about the "Hoover" effect of the F-16's. I went back to Ramstein AB, after getting out of the Marine Corps in 1989, to spend one last summer living in Germany. When dad was assigned there as the First Sergeant of the 86th AGS they were in the process of switching from the F-4 to the F-16 and everybody was moaning and groaning about how detailed they had to be on their F.O.D. walks for the F-16's in comparison to the F-4's. Anyways when I came back I worked as a civilian for the 86th CES doing landscape maintenence for the entire base. I remember we would have to schedule when we could mow the area's adjacent to the taxi ways because of the F-16's being able to "suck" in the cut grass if it was still fresh on the surface of the grass underneath. We had to cut it twice, as we were on twin 48" bladed driving mowers and the USAF was not about to spend the money on mulching mowers that big...

The F-14 was notorious for compressor stalls when first released. I’m not sure if that was an intake issue or not. Maybe larger intakes would’ve helped but the Pratt & Whitney TF-30’s they were first introduced with apparently didn’t like sudden thrust changes or severe AOA’s that a fighter pilot often needs to execute. The P&W’s were changed out to GE F-110’s on the F-14A+ model that quickly became known as the F-14B. These seem to handle the abrupt needs of a fighter jock more betters! 🤪👍

The Su-75 Femboy is an impressive fighter.

It's so stealthy the world will never see one in service

Aren't the twin tails - besides looking futuristic/cool - also helpful with reducing radar cross-section (specifically the angled twin tails)?

The Su75 is technically getting an new engine but it's not technically for the Su 75, the Izdeliye 30 engine planned for it was made for the Su-57 but current Su-57s only use Al-41s as the Izdeliye 30s are still not yet in production, supposedly they are planning on making the Izdeliye 30 Su57s around 2025 which is about in time for the Su75's first flight as well.

Sukhoi designs good jets. Despite what this guy says, I am pretty sure the engineers there know what they are doing. The engine they will use is the new Izdeliye design that the SU 57 will also be equipped with.

They should have used F-35’s dressed up with VFX details to look like these SU-75’s instead of CGI SU-57’s in TGM. Would have made a more realistic looking movie.

Fun fact, from what I recall Boeing had plans to put a more conventional tail on the X-32 before they lost out in the JSF program. They had a design ready to go, it was shown in a documentary about the competition.

Awesome take on things! Just subscribed 🎉

Awesome breakdown, it’s good to hear perspective from someone who has so much experience!

Great video. Really appreciate your input and experience in evaluation of new aircraft.

Using the v-tail angles would most likely have a better radar cross section than using the conventional ones that creates a wall for radar waves to reflect directly back to the emitting source. Flat surfaces and 90° angles make a great Target for radar returns.

Fun facts. Western stealth designs are based on theory by russian researcher Pyotr Ufimtsev. JSF program was influenced by data on the YAK-141 design, which was sourced by US intelligence after USSR collapse of the USSR. \ Aviation progress (as with all techs) is built on imitation.

Couple of things... The ruddervators are a RCS thing according to the SU engineers, you are quite right about the traditional arrangement being more manoeuvrable. SU countered by extensively testing a heavily modified Mig 21 by adding a ruddervators and a thrust vectoring jet nozzle, the results where highly impressive with the test aircraft easily out rating a late mig 29 and holding its own against the felons ability to get the nose around...! The original air intake was close to the the under chin arrangement of the eurofighter typhoon or f16 but during testing was found to cause stalled airflow into the engine during high alpha moves, thus they came up with this shape after also trying the circle/diamond shapes. The current intake is rumoured to make the most of air spilled from around the fuselage during high angle of attack flight... And lastly, the engineering, flight control systems and construction methods used in the f35 can be directly traced back to the Yak 141 soviet navel fighter program, however Lockheed didn’t steal them, they purchased them fair and square from YAK back in the late 90 if I remember correctly 👍

The SU57 just got its upgraded engines.

My thoughts: They went with a V-Tail because less control surfaces equates to less Radar signature. Also, the intake as shown is probably not the final design. Russia probably didn't want to do a full reveal on all it's technical aspects right off the bat.

I would agree, it would seem like they would have a horrible pitch authority and without that you're not going to turn a very tight circle in a dogfight.. The YF-23 didn't have that issue because the whole tail units twisted, and they were huge compared to the ones on the checkmate which really look more rudder-like and less elevator like. My biggest problem with the Checkmate is that they literally listed every "wish list" item from 5th and 6th gen planes and said "Yup! This will do that", and then claimed it would cost 1/3 as much as an F-35. How do you know a Russian is lieing? He opens his mouth. There's NO WAY they are going to pack all that tech into that plane and have it be that inexpensive. In short, this is nothing more than a Potempkin Villiage wooden mock up to scare the west. Not that it matters, they'll never be able to build them given the sanctions...

Oh man first video I saw you without a mustache!! Lol love your videos dude. 🤘🤘🤘🤘🤘💪💪💪💪✌️✌️✌️✌️✌️✌️❤️❤️❤️❤️❤️

Bro i love your positive energy in your videos. In an era of political divide it's refreshing to see a fighter pilot focus on the engineering side of the planes and not diverting into the politics

Я не уверен в том что этот парень пилот)

First time watching your videos 📹 great info 👍

11:12 As a former USN aircraft maintainer...I have my doubts on aircraft pulling =12gs..... hell 7-8 on the old EA-6B was cause for concern can assume most fighter aircraft surly don't go beyond 10g without significant non destructive tests afterwards.

Thank you for another great video Neo! I feel fully satisfied now that I know someone was hitting the 9g mark in the world, right after the like button was pushed 👍🤙 Godspeed good Sir! Look forward to your future content

I'm sure Sukhoi realizes this but just so people are aware, those missiles on external pylons could well have like 50x the radar return of everything else combined from some aspects. I would be absolutely shocked to see that on a production aircraft unless true stealth is not the priority and it's only marginal RCS reduction.

There's more than 1 reason, my friend. The X32 intake increase radar visibility and decrease the nose storage for a radar

Those are going to be 3 of the coolest planes made.

🤔🤔🤔Sukhoi is the master of air flow calculations! ! ! don't you worry.

Hi couple of my thoughts. The Su75 does have a small intake but like the Rafale which has much smaller intakes in contrast to f16s or eurofighter. Maybe it's designed to operate a little lower altitude where the air is thicker like the rafale. Just saying that's a possibility. Also regarding the v tail maybe given Russian fighters like thrust Vector engineers combining that with v-tail it could work. Also we are moving away from dog fighting so focus is on stealth. First look first kill.

This plane is a private endeavor intended for export. Russian military aviation standards require two engines, so this one won't see service in Russia, but is intended for markets where western jets aren't sold, which is pretty much everywhere outside of NATO. The first prototypes are slated to be built this year (2024). Russia does prototype aircraft cautiously, they build a few, wring them out for a year or so, noting changes along the way. This philosophy was born of the lessons learned from the days of the USSR when once a design was approved they just built it in numbers, as making changes required jumping through insurmountable bureaucratic loopholes. USSR was thick with bureaucracy. The design is intended to be easily maintained and repairable with off the shelf components, sort of the AK of fighter jets. The airframe is mostly titanium, with some aluminum and a composite skin. Rumors abound that the skin will have radar absorbing elements built into it. Russia has a virtually unlimited sanction proof supply of titanium, so most of their airframe designs capitalize on this fact. Its doubtful that this airplane will have the capability to control accompanying fighter drone "wingman" pilotless drones as does the Su-57, which allows standoff engagement of enemy planes and ground targets. The drones themselve are very impressive, said to be able to withstand sustained g loads that would crush a human pilot. There is a lot of ignorance in this comment section regarding Russia's capabilities, which is dangerous imo. Rest assured, the folks whose job it is to know are not swayed by western propaganda. Remember what Sun Tsu said about knowing your enemy.

Everyone is fully aware that the "ruddervator" is not the most aerodynamically efficient layout. It's about reducing radar returns. You're a fighter pilot. You "should" know this. It's a trade off. Ether do you value more? Aerodynamic maneuverability or low observability.

It is hard to imagine something like this coming out soon, Russia has problems with making enough Su57, and that one was in preparation for 3 decades. I believe this has near zero probability to happen.

When it comes to the intake, yeah, that's always subject to change between protos/mockups and the final design. I've seen conjectural F-32 designs where the X-32's intake is brought futher forward so the front of the aircraft looks more like a boxy Sabre. One wonders why the Russians haven't made annular intakes for modern planes? Or China for that matter. Their MIG-21 derivatives first had more forward and smaller intakes, and nowadays have side intakes.

Extraordinaire ! Magnifique démonstrations de développement Aérodynamique de ces 15 dernières années ! Tout ici est impressionnant de successions déroulentes de recherches en annulations des contraintes des effets couches limites (nombre de Raynolds ) et d annulations des effets de forces de trainées ! Une demonstration des applications de géométries projectives appliquée dans cette Aérodynamique ! Trop beau , Fan ++! Speed en démo and the Sky ! Merci Thank you merci a Tous

Physical buttons are always better than touch screen when you are piloting or driving a vehicle so that you don't need visual confirmation that you pushed the button distracting you.

Sukhoi is a russian company and russia is a european country despite the fact that most of it is in asia due to the capitol moscow being on the european continent

Personally,I think V-tails are pretty good,best example is the YF-23: It was only slightly less,if not on par with the original YF-22,and one pilot who flew both planes says such V-tails mitigated initial advantages to thrust vectoring in the YF-22. The raptor was only selected because it was marketed better.

With the center stick you can use both hands to activate it. With a side stick, it's true you have better visuals on your instruments, but at the same time, you limit the pilot to one hand only.

Hold on a sec. The su30 family is way more aerodynamic than the f15 or 16

Fun fact! The 75 in Su75 stands for the years it will take Russia to develop this airplane!

The 75 is supposed to have an engine with max thrust around 38,000 lbs. The designers are certainly dreaming with that intake.

As far as copying goes, Wally Woods taught art and his 3 rules for the commercial artist were: 1. Never draw what you can copy. 2. Never copy what you can trace. 3. Never trace what you can cut out and paste down.

As soon as i heard he said sukhoi is an asian company , i could tell this was going to be a childish biased video

It's a really crazy plane to be honest. I really like how you break it down! Thank you!

That Chintake is absolutely big enough….if that airplane is meant to never go beyond high subsonic. As a direct competitor with any modern fighter though? Nope. Also - Ruddervators DO work exceptionally well IF they are large enough. The YF-23 was nearly as maneuverable as the YF-22 (that sported vectored thrust) because it’s ruddervators were nearly as large as the entire wing surface of an F-5.

Look at LM F-16 with the F-35 intake on it for testing...it worked just fine

Nice feedback/impression. Had never thought of the stick being in the way of instrumentation when centered, thank you. Also, I believe this is supposed to mainly be a replacement for Russias Mig29 fleet (so mainly around and within RFs borders) and as an "affordable" export low visibily/stealth multirole fighter/bomber for countries who are not welcome to the F35 program or cant afford it. This is also one of the main reasons they are trying to figure it out with a single engine.

10:46 помоему здесь чётко видно куда делись стабилизаторы, поверхности отвечающие за подъём и опускание носа

Great video, brother, thank you!

Bravo Zulu Ryan! New subscriber... love your content. Press on!

Having just a "V Tail" is not a bad thing. The YF-23 had a V Tail and it was an incredible aircraft. Northrop's YF-23 offered greater range and superior stealth, but the YF-22 had a slight advantage in maneuverability.

Respect russia 😍😍😍❤️

I have an imaginary, never will be built, fighter for you to review. Did I see the Whirlpool logo on that new jet ?

With all due respect, JSC Sukhoi Corporation (Sukhoi Design Bureau), designer and partly maker of this fighter jet are located in Begovoy District, Moscow, the Russian Capital is in European part of Russian so it’s technically not Asian made. Secondly, such images are in prototypes and development I doubt it would serve the stealth and ergonomics. Thanks for sharing

Russia on fire 🔥😏

Good unbiased analysis. This guy knows his stuff. Uuurrraaa!

Stealth got intercepted in 1999 serbia 3 times 2 F117 downed in serbia 🇷🇸 and B2 shootdown over eastern Croatia

Maybe the Su-75 has auxilliary inlet doors that open when needed? They're generally a passive system as the doors are spring loaded so when the engine spools up it loweres the pressure in the duct due to the restricted intake the higher outside air pressure enters the duct by pushing the doors out of the way. (The Harrier's aren't even spring loaded, just free floating flaps!) This would allow the Su75 to have a smaller inlet because it would deliver all the air that's needed when just cruising around.

If you look at the su-57 intake size compare it to its exhaust nozzle it seems like the intakes on the su-75 are plenty big enough to feed a single engine perhaps Russian engines are not as air hungry as it’s western counter parts

"A little known aeronautical company in Asia called Sukhoi"? 🤔 this statement has prepped my mind before watching the entire content. I would not take him serious

wooo 4:05 yf-23 callout! Commenting for the algorithm gods. Good vid.

All of the worlds aircraft Experts and nerds really impress me, I don't know what you're talking about but I love hearing you talk, it's awesome 🤙

Russians are really good at designing high tech world class things on paper. Actually making them, let alone in impact level numbers is another thing all together.

That F35 engine is wound so tight, its not too safe at low speeds trying to land. How many crashes is it up to now?

Great breakdown RyDog! Now do su-35 please

I always thought the slanted tail fins were to reflect the radar away in a different direction.

The SU 75 is not even a prospect at this point.

a V tail can work provided that, the areas presented cover the requirement in area for the plan and elevation view if it has enough area for a given moment arm,I dont see an issue what it saves is, it prevents having a radar reflection trap that we would have if there was a conventional 90 degree elevator and rudder

My thoughts. First aircraft design, especially for stealth aircraft, is designed to be as maneuverable as possible while still complying with stealth requirements. The tradeoffs made, as with any engineering design, are the result of compromises taken in the comprehensive, overall design solution. The X-32 had a movable inlet specifically intended to address the high angle of attack airflow problem. It seems to me that a movable inlet, although not obvious in these preliminary design photos, will very likely be required. Jettisoning weapons to bring back the stealthiness of the aircraft would be a very expensive and wasteful idea. Just as the F-35 does, I would suggest that when maximum stealth is not required, and when a larger number of attack aircraft can be assigned to a mission, then it would make sense to maximize weapon loads by carrying external weapons. As is done with the F-35. Second, there is a clear pessimism about Russia’s ability to pay to fully develop and produce this aircraft given the history of the not stealthy enough Su-57. The Checkmate could turn out to be nothing more than a means of scaring the West. And, if it becomes anything like the Su-57, then it will not represent much of a threat to western aircraft.

The description title of the video is misleading. The description reads: "Thunderbird Fighter Pilot...." There is no such thing as Thunderbird Fighter. There is an F-16 Fighting Falcon multi-role fighting aircraft in the US Air Force, the Israeli Air Force and the Saudi Arabian air force (to name a few). A Thunderbird is a slightly modified F-16 that is not fighting capable but air show demonstration capable. Meaning, it has been modified to maximize maneuverability and speed while flying low for spectator amazement. The F-16 Thunderbird has never fought in combat and has never been a fighter jet. The video should be re-titled: F-15 Eagle air-superiority fighter jet pilot reacts to SU-75 Checkmate! That is impressive resume to say the least. The F-15 is the GREATEST fighter jet ever produced with an unbeatable combat record! And one even landed safely without one of its wings once! Amazing aircraft!

great presentation! Thanks.

0:50 Wow thanks for the update. I thought Sukhoi were Russian not Asian! Learn something new all the time on this channel.

That sure looks like a Revell with Dream Works doing the presentation.

The u.s. stole that intake design from the Russian back in the 70s/80s They used it in the X 32. I believe you can watch the video on the RU-vid channel Dark Sky's.

The F35 was a copy of the Soviet yak 141

It is funny how nobody is saying that intake of sr71 is taken from mig21. But ok, carry on...

Sincerely I don't think we will ever seen a Su-75 in mid air.

Pilot the tip of the spear...the edge of in control while out of control....respect...🇺🇸🇺🇲

“Imitation is the most sincere form of flattery” is the version that I think is most eloquent. Thanks for the video.

COOL!!! Another airplane that Sukhoi can't find a buyer for🤣🤣🤣

A V-tail is directly related to the jet's radar cross section.

Cool video! One about the French Rafale would be cool too.

Canopy bow saves weight. F16 and F22 pay a weight price for the bubble. Polycarbonate thickness for birdstrike in front drives the thickness. Canopy is excess thick on the sides ( extra weight) because its one piece. The smaller canopy with bow is also safer to punch thru in ejection. Love your videos.

We finally found all those missing spare parts from the f 35

Maybe the engine of Su-75 can work on less air as it does not have to produce thrust for vertical takeoff. But for all we know, it's wise not to disclose designs until ready

Little known aeronautics company Sukhoy? What? But I do agree that ruddervators are not effective and intake is to close to the fuselage so that the amount of air able to go inside is reduced due to laminar flow drag

Great guy you are. Wish you all the best. Thanks for your time and effort creating this presentation.

Thanks for the info .

You might be surprised, but it might not be meant as a dogfighter. It may be an interceptor that gets to the area, shoots it's missiles, and goes home much like what the MIG-25 was meant for.

Would be pretty hilarious if they took you up on your offer to test fly their jet. haha. News would have a field day.

12:54 how to say your a dinosaur without actually saying your a dinosaur.

About your argument regarding the intake, you need to take into account the thrust to weight ratio. If it is smaller, it doesn't need a bigger intake.

lot of car companies are going back on the touch screen spam for the same reason you mentioned. like every other tool people have to analyze use case instead of using a driver for putting or the reverse.

Folks who think the intake area is too small should have a look at the intake on the MiG-21. The air is compressed before it enters. In the case of the MiG-21 it was the nose cone which did it. In the case of the Su-75, it's ...

Fun fact the VTOL version of the F35 is a direct copy of the old Soviet YAK VTOL fighter.
