I looked inside Rafale, Gripen and Typhoon, and this is what I found.

Wow it’s such an underrated channnel, glad found this one.

Here's the extent of my knowledge on the matter before watching this video. 1. Deltas have low aspect ratios, and therefore have enormous tip spillage and vortices when under G. Thus they lose airspeed and energy very quickly in tight turns. 2. They were popular for a time in the 1950s and 60s because they allowed large wing areas with the relatively weak construction methods and materials available back then. 3. They fell out of favor because people figured out how to make longer wings stronger. 4. They added foreplanes fairly early - the Kfir, Viggen, some variants of the Mirage 5 (with their "moustaches") for instance - to allow for more lift, mainly at take-off and landing, and in tight turns. Without foreplanes, to produce a pitch-up moment to lift the nose, you have to deflect the elevons up, which reduces the lift the wings make (which is why you can't use them as flaps for landing). With the foreplanes, you can avoid having to deflect the elevons up, and in fact can probably use them as flaps (deflect them down), which is why the Viggen can operate on short runways. I obviously didn't know about the vortex lift, about supersonic flight considerations, and this fly-by-wire thing, which is interesting.

Thanks for the video, really enjoyed it! I usually disregard military aviation channels because they talk about useless fluff, so seeing you discuss the actual physics in play was amazing!

plz reduce the volume of music in between pause's, its really annoying

Have seen about 15 videos by this gentleman on military fighter aircrafts. Easily the best videos by genuine EXPERT. As he says 'The technical details discussed in the videos are not found on any Tube videos'. Can you please. give your introduction including your good name?

Your production quality has gotten even better since I first subbed back when you did the series on missiles! I'm interested to know, will you be following this up with a video on thrust vectoring in combination with canards, like in the Sukhoi 30 models?

Just wanted to share with you how exciting it is to get a new video from this great channel! Watching this one several times to catch it all. Thank you again for sharing your passion with us!

The instability of delta-wings is compensated by "fly-by-wire" system and helps aircraft stop on landing too.

Just because a canard has to generate more lift to trim the airplane when supersonic does not cancel its advantage. The load carried by the fore plane is subtracted from the lift needed from the main plane which can reduce it's AOA. Since the center of pressure moves aft, a jet with conventional tail a tail plane has to generate more negative lift at the tail. This not only increases drag at the tail but also the total lift (and drag) required of the main wing. So the canard has a trim drag performance benefit over a tail plane for supersonic cruise.

WHAT A JAM! YOUR VIDEOS ARE AMAZING

Great Channel, thanks for your incredible content

Very good video 👍 perfect explanation very helpful 👏👏👏 Great work keep it up 😁👌

Good analysis. This is one of good utube channel I have seen on defence tech.🙏🙏👏👏👏👏👌✌️

Amazing content!, could you do a video on the differences and purposes of the PESA and AESA radars??

This channel is gold. Cheers 🥂

Good explanation! Thanks!

Thank you for making this video.

Your knowledge is profound & deep.

This is your best video!!!

Thrust-to-weight is still very important when maneuvering in a vertical plane in BFM. Thrust itself is incredibly important in BFM since that's the only thing that helps maintain airspeed in high drag caused by high angles of attack.

OOOH good follow up would be a video on the F-4 and it funny aerodynamic fixes!

These videos are a treat for last minute revision before exams for aeronautical engineers

your videos are great and by far the most informative anywhere on the internet . I basicaly studied your videos about the gripen wich iam a huge fan of and i would really like to know more about this plane. Do you have detailed information on the cost of the gripen , like initial cost,per flight hours and maintenance ? Especially compared to the eurofighter ... Thank you very much and please keep em coming .

Awesome!

Excellent delivery of clear concepts. You do a good job please dont overdo the background music your voice is inherently sensationalizing! :D

Lovely pic of the two Aussie Mirages from 2OCU!

See you all in 5 years time when RU-vid recommends this again.

Such an underrated channel

Awesome video. It's a crime only 12k subscribers. Please if possible do a video of a possible future fighter balancing stealth with aerodynamics or maybe completely backward step by aerospace industry in that they make tiny uavs like the gremlins concept. Will fighters always be able to dodge missiles even in the NEZ environment.

Love the segues.

You should have been my teacher! Really like your vids 🖒😎

Like the paintings, in the background

The variable-sweep wing or swing wing jets of 60's and 70's tried to overcome the defiencies of the delta wing because at speed the swept wing configuration was effectively a delta shape. Much cheaper and easier to stick a canard and let the onboard computer sort it out.

I'm no engineer, but what I don't get is: how is such a thin plane as a canard attached to the fuselage strongly enough to withstand the forces on it?? I mean, if we stick a hand out of a car window on the highway, we're impressed by the force of air at 100km/hr (60 mph). But these skinny little foreplanes have to be attached firmly enough to hold up under multiple-G manoeuvres - at speeds sometimes approaching Mach 2! Can you imagine the engineering at the joint? And then you have servo systems to twist them, also against those forces!! Boggles the mind.

Where are you from? I also used to say 'surfeises' to pronounce surfaces (séerfases). Enjoyed so much this FBW explanation

You forgot the Mirage 4000

Could you Do a Video on LERX(Used on Super-Hornet) and Chine(Used on F-16 & F-22)? Which is Better?

Though you briefly covered it with the ending comments the Gripe and Euro fighter are much more tail heavy so they don't deploy the elevons in a flapped lifting configuration and in most subsonic flight envelopes you see the canard acting as flow control devices where they pitch opposite the vectored direction of flight i.e in a pitch up the canard mainly pitch down NOT to compensate for the crafts tail heaviness but to reduce detached air flow over the root much like the leading edge flap pitch down to help maintain laminar flow from detaching from the top side of the wing....most airshow routines displaying their maneuverability is both subsonic and show the canard pitched down the most...

I found a mistake which makes me proud because there are almost none in this channel. 11:30 a canard and a horizontal stabilizer work in opposite because they are on the opposite side of aerodynamic center.

On recent delta wing designs, an honourable mention on the F-16X and the IAI Lavi.

Thaknk you for you vidoes. About the canards, have you never eard of the negativ effect for the pilot vision in direction of the ground with the Eurofighter ? One more time, a fighter planed to be a interceptor have to ensure missions of a ground attack aircraft... With some inconvenients... The canards are placed beside the pilot. For the Grippen and Rafale they are on the rearside of the pilot, so they can have a good vision to the ground...

i love the eurofighter

Thanks 😊 for discussing this topic in detail. But can you after wards discuss the possibility of increasing stealth performance of a canard Delta configuration aircraft!!??

Bro, why does this guy hold a grudge against Gripen and J-10? Those were like two of my fav fighters XD

Very interesting the differences in canard foreplane usage in different parts of the globe. The Americans experiment a lot with them such as the XB-70, X-29, X-31, and F-15 STOL/MTD yet never put them into operational practice. The Europeans have gone full-on canard with the Rafale, Typhoon, and Gripen. The Russians meanwhile like the Americans experiment with the likes of the MiG 1.44 and the Sukhoi Su-47, yet adopted a sort of 'tri-plane' approach with the Su-30.

SPECIAL MANEUVERS FOR CANARDS: 10:40

Su 30 su 34 also have cannard but why its there in conventional wing plane? Also can you make a video about j20 unusual proportion configuration?

Io volevo ringraziare di cuore l'autore della serie di video sull'ala a delta. Parlando con calma e scandendo le parole, aiutandosi con gesti e disegni, riesce a far capire tutto anche a chi, colpevolmente,non conosce la lingua Inglese. video interessantissimi.-----I wanted to thank the author of the video series on the delta wing. Speaking calmly and articulating words, helping himself with gestures and drawings, he can understand everything even to those who, guilty, do not know the English language. Very interesting videos.

If the fighter jet is equipped with two engines should they be rotating in different directions ? Just asking from curiosity because wouldn't it be beneficial for that vortex on top of wing to rotate in the same direction as engine?

I always thought that canards had a real advantage at take off because they generated POSITIVE and rotational lift. Compared to conventional aircraft where the elevator had to generate NEGATIVE lift to impart rotation at take off 🤔.. I now know more 👍

Father of Canards is Alberto Santos Dumont, a Brazilian inventor, wich in 1906 made his flight with 14-bis, the airplane Wich have the canard configuration.

love those canards

How come you didn't mention or show a video of the F-16 AVTI when talking about Direct Force Maneuvering

I love your voice ..can hear you for hours.....you should do asmr videos too...u have the talent

Can someone link me the videos he mentioned? also id like to know what whould be the effect of forward swept canards.

What about on a/c which could suddenly loose "canard control" during landing ? Is it an unstable or critcal condition ?

As an interesting adjunct to this video, it would be cool if you could do another video analysing why the designers of the gripen/rafale went with a close-coupled arrangement of the canards, and the designers of the typhoon went with a long-arm arrangement. I get the feeling the designers of the typhoon missed a trick by not positioning the canards to strongly interact with the main wing, a view supported by the fact that Airbus developed the AMK to remedy these shortcomings. Short of directly asking the designers what their intentions were, a video from you could help clear up the advantages and disadvantages of each solution

I know one thing that Can defeat foreplanes. Five planes.

Canards allow for maneuvers that change elevation without changing the pitch of the airframe. Is this same maneuver possible using LEVCON/active-LERX?

Nice video. Could you please rone down the background music

Helps them move faster in turning performance ah and in also have good angles off attack rafale gripen eurofighter su 30 mki su 34 mig 1.44 j 20 chitah f 15 advanced j 10 etc...

My favorite canard, even though it is not technically a canard, is of Piaggio Avati's two whiskers.

Well the Chinese still have chosen a delta + canards configuration while having stealth as a main concern when they designed their most advanced fighter. They're the only ones doing so however and questions arise about how low observable is the J20.

if i may ask- why not use thick deltas (generating lift at low angles of attack) for subsonic aircraft? wouldn't the lack of a pronounced trailing edge reduce the induced drag?

Just note that at 11:30 the flaps at the rear of the main wing should be directed upwards, and not downwards to create the upward lift force direction shown.

I would like to point out that canard configurations are not inherently unstable. Lifting canards with a wing giving a center of lift behind the center of gravity are stable designs and have been used in designs without fly-by-wire such as the Kyushu J7W and several designs by Burt Rutan. Additionally, while the canard delta wing combination is very good for aircraft with neutral stability, some modern fighter aircraft might prefer instability. For a canard delta wing combo to be unstable, the canard would have to produce downforce while in steady level flight, robbing it of one of its key aerodynamic advantages, meanwhile and unstable wing and tail design would have a lifting tail, reducing overall drag. There are more reasons than just stealth to choose a conventional wing and tail design.

What is rational behind selecting between closed coupled and long couples canard ? J10 and typhoon looks to be long coupled and gripen and rafale looks like closed couple canard. Indian mwf tejas with ge414 97kn engine most probably use close coupled canard.

If vortex lift is so beneficial to deltas and delta canards, why not enhance the phenomena even further with leading edge root extensions, or even LEVCONs? And is there any benefit to adding a forward sweep to the trailing edge of a delta and turn it into a diamond shaped wing like the YF23, like further extending the duration that vortex lift provides benefits?

This is sound like strong wind who hit the aircraft in any direction ?Are they foreplanes like propeller (in smaller speed ) to cut strong wind or atmospheric pressure?

In my head: Is this a Bullpup version of an conventional fighter jet?!

The Atlas Cheeta & Israeli Kfri all so had canards back in the 80's

The delta wing is on the F-15, even though it has an empanage. The F-18 has a double delta wing. The canards help greatly with low speed handling. The brilliant and imaginative Burt Rutan used the canard is many of his designs.

The IAI Lavi was one of the first aircraft to use this configuration.

I’m just curious, how do you think the J-20 can be stealthy if they have these huge foreplanes

Very Very interesting. Very cool Maybe we should go back to Supermarine Spitfires. Back in the sixties the Brits flew a Griffon engine Spit against an English Electric Lightning because they thought the Lightning would come up against Indonesian P-51 Mustangs. Would like to hear your comments on this one for sure. Just how far can we take this fighter technology. Will the 6th generation fighters be pilot-less?

I enjoy your very informative videos. Please consider discontinuing the annoying background music which makes it difficult to hear what you are saying

Does 3D vector thrust engines replace the need for canards? a la some versions of the Su-30

The problem i dont understand that canards have is that they have a steeper aoa then the plane itself, thus they will stall out sooner. thats why i still think rear horizontal stabilizers are better.

Grazie, par bene!

What is the configuration of Saab viggen

So Delta / Canard design with Non-loaded Canards steers like a Car ? Rudder obviously counters Yaw or induces it , as required , but it seems to me the Plane FRONT steers . Less like a Boat than Conventional Configuration . Comments ?

But, the Eurofighter Typhoon doesn't have close coupled cannards, correct? The cannards are placed at a long distance from the wings! So this design deviates from the Gripen and Rafale, correct?

Next episode: Variable sweep canards.

Its another way around other than thrust vectoring

Back in the 1980s, USAF "Aim High" logos featured canard configuration jet profile. I think that at the time, the HiMAT was really hot stuff, so the USAF logo designers must have just assumed the next USAF fighters would be canard jets. Oops!

Why bomber can destroy enemy radar without detecting or tracking like b52

What about lEVCONS as in su 57 , can it really act as a canards?

Is delta canard the reason why variable wing design is dead?

Foreplanes? I always refer to them as Canard and they have been around since the beginning.. I mean literally

They are called “canards,” literally “ducks.”

did you know that the 1st jet aircraft to break the 1000 mph barrier was delta wing & british? yip so in classic style the brits gave the Fairey Delta 2 data to the french who were so impressed they made 1000s mirage's with that wing concept!

Why delta wing config is detrimental to stealth??

Pls mack video jf 17 thunder

what about manuverabiity ?

Just a suggestion. Lower the background music.

Please take consideration to balance your music and vocal volume during editing. Slow vocal, then suddenly a loud music. Not good.

Are you implying that 737 max instability can be solved by installing a foreplane?

Hi you are requested to analyze JF 17's design n blocks 1,2&3

CANARD Must be better on take off -contributing LIFT to nose during rotation , rather than conventional tail which produces DOWNFORCE during this critical phase ?? Especially when you design a high speed fighter , and then wan to strap-on tons of tanks , air to ground etc ?? Wales UK
