@Era_923 you deleted the posts which showed that your country man has less than average IQ.

Apart from my last post, tell me 1 rule that any other of my posts violated which your country men are not breaking on regular occassions.

I will invite each and every other mod here and teach you some.

I will quote some of your countrymen from yesterday and day before yesterday, and I will hold you to do the same.

Waiting ....

if you have anything to breach my comment here you are.and do it in a civil way(not like a wild animal)
anyway you noticed a good point which proves your stupidity at best.

P+1/2dv2+dgh=constant
in this formula P shows pressure,d shows density,v shows speed,h shows elevation and g shows earth's gravity.which shows weight?moron!this exactly shows how moron you are.you even didnot check your own source....OMG

:mosamania@
you just shut up

The equation you have given is for incompressible fluid.While it works at low speed,it completely fails at high speed ant to the extent that some properties of fluid simply become exactly opposite to what they are at low speeds.

Compressibility could have large effect on fluid mechanics of objects.An RC model's flight does not prove anything.

Fluid flow is divided in three categories conventionally and five contemporarily.

1.Incompressible flow : less than Mach 0.3 at which your equation is true.

2.Compressible Subsonic: Mach 0.3 to Mach 1

3.Compressible Supersonic: Greater than Mach 1

See page 28 and 38 of attached tutorial.

While the flight of an RC model proves nothing,flight of a scale model in wind tunnel is enough to prove feasibility of a design.It is not dependent on Size.

The so called plane has a long list of shortcomings which put into doubt the very probability of its self powered flight starting with being not large enough to house a decent engine,air uptake ducts which are neither big enough to sustain high altitude and high speed flight and would choke engine completely at high AoA,lack of weapon bay and design of aerofoil which would produce very poor lift for given thrust.

The flight of an RC model is not indicative of design integrity.It is unpowered subsonic flight.

In an unpowered flight,you could make a piano fly.The jet if Iran persist could get airborne but it would be a limping lightly armed subsonic jet having rate of climb worse than a cessna and with dubious stealth characteristics.


@Era_923 and @Mosamania

You people should go a little light on censorship.Half of the post in any thread related to middle east are deleted and people receive infraction for advocating PoV of their countries( I am talking about Syrian issues).People are not juvenile that their fragile sensitivities should be respected.Only outright abusive posts need deletion.

your point is same aerodynamic shapes have different behaviour in different sizes.sth which is completely wrong.as i said same wings with same air-foils but in different sizes have same reaction to the moving air however they produce different amount of lift.

on the other hand you mentioned a formual that does not mention weight as a factor anymore.

I will write your answer here so all other members would see it.
I have edited quite enough of your posts and those of Kollang's in which you have called each other fools, stupids and morons.
You should be thankful you haven't received infraction, same as Kollang. You can inform other mods too if you want.
Now stay on topic and if you have anything to say send PMs to me.
As long as you discuss the topic and don't insult anybody, you are safe.

I barely delete posts or give infractions my friend.But you should understand ME sections are also full of trolls, fake accounts, internet suicide bombers and etc.So sometimes being too soft is not good.
Actually many members, Iranians and non-Iranians send me PM almost everyday and tell I'm even soft on the trolls here.There is no censorship here and this forum is not mine to censor anything.

nice comment!thank you,sir!
well it was only an reply to salman's statement in order to prove he is not right.

While flaming on middle eastern related threads is higher even than on India and pakistan related threads (only Bangladeshi section has higher degree of rampant imbecility),even troll posts could be informative and should be allowed to stay(personal opinion).Only flaimbaits and name calling/Slandring posts need be deleted.

Regarding infractions,what i mean with that is the frequency of partisan members getting banned is very high.Syrian lion is die hard supported of assad which is pretty explainable given the fact that he is a syrian christian.Getting infractions for being delusional propagandist is not correct.It is natural for him to be negative towards saudi's and FSA.

And trolling is relativistic.Some days ago even webmaster trolled on a terrorism related thread.And a forum is made of its members not it's server location.It is yours to censor but that censorship should be within bounds.
 
Fars news interviewed F-313 Project manager today. if any of Persian speakers have time translate it for non Persian speakers please.
interview has some technical info and maybe useful for discussions here.

well who has the patience for all of it But it's some highlights from the interview

This airplane is designed to answer our needs , if we wanted to copy a US , Russian or European fighter then we had to change our needs and strategies according to their needs.

The RC model of the plane that tested was using a Jet Engine
the design of the plane and its broken surface made it lose some of the aerodynamic features ,but we reached an optimum point between the aerodynamic feature and the design.
the lift in older generation of the fighters were due the the wings but in newer generations it is more due to the body rater the wing.
This plane can work at the high altitude , middle and low altitude , but it's main feature is designed to work best at low altitude
which usually cant be found in such airplanes around the world .

The use of broken wings in this plane allow it to fly in all altitude.
This plane is designed so it can use the ground effect in its flight , while other fighter around the world because more optimized for high altitude operations have problem using Ground effect.

the airplane that was shown was not a mock-up it was the test plane but we didn't feel it's necessary that at this stage install all the equipment inside it.
this airplane will use HUD that soon will be installed on it (Well here I must sadly say bye bye helmet mounted HUD)
the finished airplane will feature Full glass cockpit and the Analog display in the test plane will be replaced by digital equipment.
in all the world at the test phase they retain some Analog equipment so if there b a problem the pilot can use them .
we already designed and built an indigenous ejection sit that we are waiting to get all the necessary permissions to use it in the plane instead of the foreign model we already used in the test plane.
the air intake for the engine is designed to work at higher than 26 degree angle

this test model didn't have a flight test and it was some media error that said this airplane had previously flown . in near future we began Taxi and Flight test of the Aircraft .
 
difference between a 4,5 gen fighter and a 3,1 gen fighter.
