Ghaher 313 fighter

I am an engineer, also not in aerodynamics, the aviation is my hobby so I have knowledge in aerodynamics.


Yes, there are people who know aerodynamics in Iran, but why bother and call them if you are buying their lame fake anyway? Mullahs learned that whatever they say you will buy it, so they simply dont care.


Double wings (biplane) and thick wing profile - all that belongs to WW1 era.


As I said, what matters is lift/drag ratio. And this ratio will be lower, much lower. Thats why no one makes fighters with double wings since middle of 1930-es. Except Iran


If you want to improve low speed maneuverability, you need big straight wings like A-10. This thing's wings are bad in everything: they are bad for supersonic because they are thick and double, they are bad for subsonic speeds because they are small and too much canted.

So overall its complete joke that will never fly.

biomedical has nothing to do with aviation so kindly get out of this kind of discussion.aerodynamic is a complex science and cant be considered as a hobby.

****!see who i am talking with.this guy consider ww1 double winged design and F-313's double winged design as same things!

calculating ratio between lift and drag reqiures certain formulas.thats not sth a kid like you(and me) can do.

kindly get out of this.you know nothing about this complex science.

 

[kollang]

They were correct.


Fact remains: Iran is the only country since middle of 1930-es who made a fighter with double wings

and new FACT:that fighter can bring down any israeli flying object as hell.have fun with it.

Thickness make more stability in low speed no problem if you have strong engine or in light small planes .

The more the thinkness of the wing that more will be the drag.
More the drag, the more will be stress on the wing structure.
to a point where the truss can't take it and just rip apart.

oh for God's sake stop it.i told you the reason and again you are repeating this more and more?OMG....
as i said as forward wings(so called canards) rip the air first there will be less drag F on the main wing,on the other hand thick wing increase lift force.thats indeed a smart design i must say.

you do realize that the wing actually needs a certain Volume of fluid incident on it to produce lift.
If the front wing is "ripping" the air as you say, then there won't be very much left for the rear wing to poduce lift.

Science, any leading wing produces vortexes which cause terbulance and decrease the effeciency of the main wing.
This is why "Canards" are left small, because they are only control surfaces, not lift surface.

If we use your logic, than it can also be proved

use carbon instead of titanium

Use carbon what ?

At least google what you are saying before posting it !

 

[Hack-Hook]

well I wonder why discussing if this platform is able to fly or not , didn't Iran proved that this design is flyable by producing a remote control version of it that could fly.

In your world all graphs are straight line and follow the

y = mX + C ?

When you say things like you did, you make your self a bigger fool than before, and you rape science, and the indsutry and the hardwork and the profession thousands of people dedicate their lives to.

well won't it be easier to answer my question directly instead such cryptic ways? Do you believe the Aerodynamics of a RC model is different than one of a Real Airplane ?

the problem is flying in high-speed.question is can F-313 fly with the speed of over 1 mach easily?

 

[Hack-Hook]

well thee is no doubt that more speed is always desirable but to be honest , is it all ? if you can made a tighter turn at lower speed than your faster opponent in a dogfight then who has the advantage ?
didn't In fighter training program in USA the instructors usually used slower and smaller but more agile aircraft but bagged a lot of wins at the end of day ?

That was not cryptic, it was equation of a straight line.

and yes offcourse the flight characteristics are different from a model plane to an actual flying machine.

It is blashmous to imagine otherwise.

Now, let me ask you a question .. and I want you to think, research and then answer.

You and Persia gang were after the member 500, on the premise that he is a biomedical engineer. Thus his comments regarding the plane were not worthy ....

Do you people think you should be harping here .. considering you couldn't tell the equation of a straight line ?

 

[giger]

what is the difference in 1/5 model ?I think there is no difference aspect engine it can fly over 1 mach with a powerful engine.

Good for you.

I see a place for you in the Irani air force, right at the top !

Good luck.
