count the front landing gears

Sir JEeeeeee
PLeaseeeeee

some day back you come up with a PGM being carried in internal weapons bay and now these...

by the way 8 front landing gears!

but there is a small problem sir!
the ones on the far side are missing THE AIRCRAFT!!!

 

[fjavaid]

count the front landing gears

The green section between the fuselage is of more interest to me .... this clearly shows Composites % increased in JFTs......

 

[monitor]

^^^ What is the logic green section are composite material

 

[shbaziz]

Ohhh... Irfan Bhai u deleted the "article". I was about to start trolling

 

[SQ8]

And I thought F 404 was an after-burning turbofan....and it couldnt maintain constant pressure in the compressors and hence was called a 'leaky' engine.

And Mod I thnk we might end up derailing the thread...so we will stop here.

It was derived from the YJ-101 turbojet used for the YF-17.. it is in essence a turbofan with a turbojet within it.. hence it "leaks" air from the turbojets flow into the turbofan...which is why its called the "leaky turbojet".

The green section between the fuselage is of more interest to me .... this clearly shows Composites % increased in JFTs......

OR just a different alloy with a different primer.. nothing more.

That green side shows that there is some new work other wise the composites would have been yellow there too.

Please stop thinking of yourself as the ultimate wise guy, you think these issues were not considered by the users/ developers of the weapon system? Ever heard of Gripen NG? it has an AESA radar (vixen series) and which engine does it use? it is not the monstrous F-100/110 but a medium sized F414 ranging at around 85-90 kn. Power management on an aircraft does not mean to equip it with most powerful engine out there always, it also requires complex integration optimization to get maximum out of it.

All he said is, that the current engine might not offer enough power to be used with an AESA radar, not that the fighter needs the highest thrust engine and for the same reasons the Swedes went from RM12 (GE 404 version) with 80kN thrust, to GE 414G with 98kN. So when you bring up this comparison, you are contradicting yourself and supporting mafiyas point basically.

What's strange in this discussion though is the fact that you guys take the AB thrust of the engines in relation to the radar power. Shouldn't the dry thrust be the more important figure in this regard? Here we see the JF 17 in a clear disadvantage against all comparable fighters:

JF 17 B1 - 49kN
Gripen C / NG - 54 / 67kN (according Volvo Aero specs)
Mirage 2000 (test aircraft for RBE 2 AESA) - 64kN
F16 B60 - 84kN
J10B - ?

When you look at these specs, you can't deny that mafiya might have a point with his doubt about enough power for an AESA radar.

A quick question... At Zhuhai 2010, Kilmov poster claimed RD-93's thrust to be upto 98KN.

It didn't claimed 98kN but showed the thrust range of this engine series between 79 and 98kN, while the latter is only possible if it's based on the RD 33MK changes.

For cooling.. not for the T/R modules. Cooling is the basic issue that is keeping an AESA from making it into the JF-17..
There is an alternative solution to that but for now its too radical and too expensive to consider for Batch-II.
So the KLJ-7 is going to have to do.. which is ok, since its a great PD system nonetheless.

Still, the dry power should be the important spec shouldn't it?

It is, but in this case WRT to the range req dependant on aperture size.. its enough.
There is not enough space though ..to provide adequate cooling for the AESA solution currently available for the JFT.

 

[ziaulislam]

people use to say that JF-17 nose was quite large..so why is the space an issue for AESA?

or does in the end , the issue comes of the cost for the solution?

Space is not the only thing to be kept in mind before installing a radar. Weight, electricity, cooling and changes required in both hardware and software are the main concern as well.

no no no no listen to me this time its clear image we can see 8 thunders here man please use your imagination . its not fake man its true original pure image from kamra
