From well available stats, go look them up!!!So you pulled your facts out of ur *** and then resort to name calling when caught out.

To what end? Iran had much more credible projects that could have been used for propaganda.
People had forgotten about Q-313 until the defense minister brought it up again.
Even if we assume it was and is a lie, each one of them is just increasing people's expectations. Now everyone expects to see it fly. And according to the same defense minister, it is supposed to happen this year.
Why would someone, like the MOD, put himself in such an awkward situation?
Problem is that fat wing aircraft at speeds post 700 km/h will increase drag, the aerodynamic focus will move backward causing bad control.Before starting to write and accuse someone of misleading others, spend a bit of time to read the post and it's background.
@500 claimed that Q-313 can at most fly around 500 km/hr. I showed that with the current two engines, Q-313 can easily fly at speed above 1000 km/hr. My calculations were for subsonic speed and the drag coefficient that I used is for subsonic speed.
And it is not like the drag coefficient increases 10 folds at supersonic speed. F-4 subsonic drag coefficient is 0.021 and it's supersonic is 0.044. Something that can easily be overcome by adding after burner to current engines.
Finally, if you paid more attention to what I had written, you could see that I said that speed is more than enough for a ground attack jet. Q-313 doesn't need to be supersonic for its intended use but it's not also be slower than WWII aircrafts as some like to claim here.
I'm not an expert but from what I understand from the text below does it mean anything about the thickness of the main wing or not!?Problem is that fat wing aircraft at speeds post 700 km/h will increase drag, the aerodynamic focus will move backward causing bad control.
Look at subsonic (less than 1000 km/h) Su-25:
It has large flaps, leading edge slats, slot between intakes and the fuselage. Now check Qaher:
Only small aileron and spoiler.

Rather than use the conventional tailplane configuration found on most aircraft, an aircraft designer may adopt the canard configuration to reduce the main wing loading, to better control the main wing airflow, or to increase the aircraft’s maneuverability, especially at high angles of attack or during a stall.

New Recruit
It's not about weight they need methane jet engines to go higherI believe so.
Because it uses 2 x modified J85 same as Saegheh and I think it weights not much more.
Then the canards had better be active flight controls elements, aka movable. From what we have seen so far, the F-313's canards are fixed, aka passive flight controls elements.I'm not an expert but from what I understand from the text below does it mean anything about the thickness of the main wing or not!?

Wing has 3 basic profiles. Subsonic, transonic and supersonic:
In order to improve wing performance at lows speeds (for example during take off and landing), transonic and supersonic wings are equipped with large flaps and leading edge slats.

On this scheme:
yellow - leading edge slats
green - flaps
red - ailerons
blue - spoilers (they are used during landings to decrease wing's lift)
Now lets check Qaher wings again:
It lacks leading edge slats and flaps and has only ailerons and spoilers. So it proves again that thats subsonic wing. Subsonic fat wing does not need flaps and slats because it is already optimized for low speeds.

You once again proved that your knowledge about aerodynamics is lower than a 5 years old kid with an Internet!I am talking about wing here.

Beware of guys like 500.
There is a group of Israelis of their intelligence ministry on the forums of the internet that have the task to gather information. One of their tricks is to make strange claims and hope for a Iranian with insider information to come and argue with them, in hope that they release useful information.
So don't fall for this 500km/h max. BS one of their typical insult like claims to fire up emotions.
A tandem wing design such as on the Qaher will lead to a disrupted airflow at the rear wings where wing profile thickness rule of a conventional wing don't count anymore. I still think its a high subsonic design but ignore those 500km/h claims.
Well 500 is in fact Yuzi Robin. He copied one of Soheil's renderings for Simorgh Satellite Carrier for one of his speeches in Washington DC.Beware of guys like 500.

Many of Israelis showing interest in Iran's defense projects are in fact Iranian Jews who have immigrated to Israel.I had a feeling something like that was going on. An Israeli wanting a mutual conversation with Iranian and Muslims in general is kinda fishy but nonetheless. I don't think many people outside of the engineering team work on on the qaher - 313 know it's final specs as well as what its final configuration will be. Online intelligence gathering through forums on the Iranian military is a rather assanine approach since most of Iran's military is shrouded in ambiguity.
We give our best guesses but concrete conclusions is something none can really come to.
Iran air force (from right to left) MIG-29, F14 and F-4, SU-24 and Mirage F1. Mirage F-1 itself is relatively small.For people who think it is a "small" plane; F-1 Mirage.
