Where is the tailplane at a F-22 or T50 small?!
You can roll with TVC but the momentum arm is not very usefull for this task, real split evelons, ailerons or blown ailerons make the even better task.
TVC is usefull for Aircircus (irrelevant low speed) and can cure some aerdynamical design failures.
The use of the tail as evelon together with flaperons caused some non-linearity on the tail, make headches through the boundary layer from the wing generate a dead zone where the tail within is less effectiv.

Any wing has ailerons and trailing edge flaps AKA elevons, any aircraft with canards or tailplanes can use them, there is not such thing like canards only can use ailerons and flaps. The same pitch force flaps generate can be generated on an F-16, Mirage 2000 or Gripen.

But with a tailplane is the momentum arm much shorter (wing) and when you deflect the trailing edge flaps upwards then generate you downforce and more drag (bleed more energy, wave drag on the hing line at transonic and a lower Mach crit!), in the oposit direction the same. The momentum arm is to short on a wing at a tailed plane. On transonic and supersonic forget the increase of chamber it’s really not usefull, it’s only obstructive (increase the wave drag).

An aircraft with tailplanes can use exclusively the flaps as flaps just to increase the camber of the wing but a tailess uses them as elevons since it lacks a tail.
Tailplanes can be used asymmetricaly as roll control or togather as pitch control.

But we speak about Carnards and not clean Deltas!
The Canard do the job what the tail at tailed plane do.
Sure tailplanes can used as roll controll but the momentum arm is much shorter as for ailerons on the wing, the same can do a Canard too. So what? It’s more a crook when you need all flaps (F-18, F14, MRCA Tornado etc.) or when the ailerons are uselees at high sweep angle (F-14 and MRCA Tornado etc.)
The resulting momentum arm (elevator) is on a Canard much longer as on a tailed jet.:diablo:

Quote my self

But Rafale, Typhoon and other Carnards have the benefit of two moment arms.
Not only the Carnard is used as elevator the ailerons acts as elevator too.

The resulting momentum arm for a Canard with dual elevator is much longer as for conventional tailed fighter.
Then should we not forget relaxed or negativ stability degrade the momentum arm at a tailed plane! A Carnard can use therefor a negativer MAC% (higher instability) as a tailed fighter.;)

They are tailess with a compound wing

Then has this concept study a F-18 style inlet under the LERX and the 2D nozzle above the wing!
Then is this more based on Lipisch, Horten (not really new) and the NASA says that such a configuration not really good in the transsonic behavior (prone for oscillation and low lateral stability).

And we know after your teaching session, that a tailless fighter is crap.:diablo:

I can see a canard there.. and no LERX… :confused:

edit: it was just a shadow that made it look like a canard, it’s LERX, sorry….

No, it’s a Canard, or where is the LERX in the light and the Canard is above the wing leading edge!
On this a little bit greater picture can we see better that this F-XX has Carnards but no LERX and no LEVCON.

This one is easy … MIG-31 :rolleyes:

MiG-31 use a PESA and the small Tornado nose Radar (TFR Terrain Follow Radar) is a S-Band AESA.
