JF-17 Thunder Multirole Fighter [Thread 5]

[sancho]

oh Yes. But do we have any 'official brochure' of the "KLJ-7V2" ?


New modes like ? Doesn't it already have all modes that are required in a Modern day Radar ?


You sound so sure....... how can you say ?

Because senior Pakistani members had confirmed this plenty of times in this very thread!

ohhhhhhhhhh bhai no they are bombs but guided can move like missile and hit the target while aircraft can stay away from target area . simple words if target is 110km from pak border jets can stay in the border and fire stand off weapon and come back from stand-off range. it will not be missile attack but stand of weapon attack

read it bro

Glide bomb - Wikipedia, the free encyclopedia

if they fire RAAD ALCM then it will consider as stand off cruse missile attack

here is H-4 image of S.african system

Bhai seedhi baat hai. Wo bombs hain magar zara pohnche huwe hain!!

Great read all info here.

Thanks to @Oscar for the initial link of raptor ll

and now Paf version H-4.

helmet looks too old lolz

HGU-55s, came with the first blk-15s, too old but comfy for pilots

my old post from 2011 on klj-7v2

664-670 mm as per my info housed within a composite dome of approximately 740 mm, klj-7 V2 will have the size of around 700 mm as there is ample space available for a bigger antenna for future upgrade.

So that means it can accommodate 1000 plus/minus TR module AESA eventually. Is that a fair assessment?

theoratically yes

Maybe, but not without addressing the problem of cooling so many modules. AESA generates a lot of heat and therefore must have a mechanism for cooling. A possible AESA radar in JF-17 must address this problem. It is a small aircraft, and installing a cooling solution would be a bit of a challenge. So, one can not just make a guess based on diameter of Radar cone. Quite a few things more would need to be considered for installing AESA.

I would like to see AESA as much as anyone else, but still there are challenging problems in the way.

Maybe in block 3 for which they are planning AESA they'll redesign internal layout of equipments to make space for cooling system after all JFT has almost similar length and dimensions as an F-16. I think (and I am hypothesising) the mechanical yaw and roll controls are one of the big culprits in terms of weight and space penalties and need to be replaced with full FBW.

if we can bundle a grifo-7 with F-7p with virtually no space for a decent radar antenna, jf-17s is no big deal

on a serious note, the aesa being developed is going to address the cooling issue. obvious isnt it?

Cooling electronics is not as easy as simply blowing cold air.

Keeping electronics cool in the Antarctic: harder than you think
Bill Schweber -January 09, 2014

Say what...??? Keeping electronics cool is a problem in the Antarctic?

You can't let the electronics get too hot or too cool, and there is other equipment in the enclosure that also has to be thermally managed. But the real thermal problem in the Antarctic is that the air is extremely dry, and so loses much of its convection capacity (whether natural-convection unforced or fan-driven forced type).

Aircraft and spacecraft designers are well aware of it, and know that in the vacuum of space, there is no convection cooling; there is only radiation cooling.

Cooling sophisticated avionics is very much a precision science. A jet fighter have greater odds of variation of operating altitude than an airliner and not only can a jet fighter change altitudes many times in a sortie, the rate of changes is also much greater. Humidity assists in convection cooling and the higher the altitude, the less humidity is available due to more rarified air.

Some avionics sub-systems, usually data processing where low wattage is the norm, are best served by convection cooling, meaning cooler ambient but relatively static air are used. Static electricity is the main concern here.

Some, such as klystrons or traveling wave tubes (TWT) whose roles are to generate those transmissions signals, are better served by forced cooling air across heat conducting radiators (fins) or even directly over the electronics themselves.

Datasheet: 1900TP1G2z5 Broadband TWT Microwave Amplifier

The Model 1900TP1G2z5 is a self contained, forced air cooled, broadband traveling wave tube (TWT) microwave amplifier designed for pulse applications at low duty factors where instantaneous bandwidth and high gain are required. A reliable TWT provides a conservative 1900 watts minimum peak RF pulse power at the amplifier output connector. Stated power specifications are at the fundamental frequency.

Retrofitting a current fighter platform to advanced AESA radar avionics will require detailed analysis of the current aircraft ECS and probably complete replacement of the same.

Hi,

Good man---you learning about aesa---good for you. People think that making of an aesa radar is easy----having no clue about the difficulties.
