Infra-Red Search & Track (IRST) Systems

keeping Chogy's point in mind that IRST cant give accurate results in different weather conditions hence cannot replace Radar. But as i mentioned before that a large IRST and a small size Radar (which is used in UAVs like we have in Falco) for limited scanning and tracking purpose, could become a deadly combination for ANTI STEALTH Purpose in clear weather conditions and high altitude interception of Stealth bombers.

i am a lil bit late here for posting my concept drawing, my apologise. People might laugh or make fun of it but it is just to show what i thought it has to be. Its not accurate and not well studied and i am not an engineer though but still i am presenting my IDEA here that i think is quite applicable.


Its an imaginary ANIT STEALTH THUNDER.
1 - Top view of it showing placement of LARGE IRST and Small AESA Radar.
2 - Side view, placement of radar and IRST shows how exactly it will increase the width of the aircraft nose.
3 - Front view - (worse details)
4 - Radar portion (lower nose) can be covered by normal composites used to make Radome while rest of the nose can be made of some light weight optical material like Fibreglass.
5- Sqn Marking

What u ppl say ?

 

A Layman Question, How Does IRST have Look Down capability, i mean, IRST is fixed on Canopy, then how does it look down and take pictures of ground based targets? Take example of this IRST

^^ur answer from another site:

Now do remember the bold part that not only main but complete optronic system is utilised for detection in every aspect/direction...components if which also are present in the tail fins; LERX; wing tips...

 

Lockheed Martin IRST 21 mounted on a centerline 480 Gallon fuel tank of an F18F. After modification can still hold 330 Gallons of fuel.

When you have time, kindly go through this article on IRST:

Infrared Search And Track Systems And The Future Of The US Fighter Force

 

its quiet big for an irst. the pirate irst for the typhoon is quiet small

Bro it's mated to a fuel tank. Meaning, plug and play, no modifications to the aircraft is necessary. Secondly, should a user require the aircraft to carry it , you can mount the ISRST 21 on to the aircraft as well.

 

Hi,

Thank you fort that article----and that is what has surprised me----why the JF17 did not come with a dedicated IRST on its body---rather than the pod taking a hard point.

What do you think.

Hi,

500 km---that is an outrageous distance----

Your picture not visible.

 

Well, some smart a$$ TT on this forum was arguing with you and me, that IRST range is less than Radar. This was true a decade ago. Not today.

Hypothetically speaking, when the JF-17 was being designed, maybe this was the assumption.

Now what can be done today? It can be fitted on to the aircraft, just like the J10. Or a less costly approach would be, to modify fuel tanks to carry it. Problem is, fuel tanks can be dumped, but one equipped with an IRST can't.

I honestly don't know IF Skyward-G by Selex, is available to the PAF, but if it is, then they should definitely go for it.

Another thing they should lookin to is Brite Cloud.

Ho,

Or they can dump the machine gun and use the hard point for IRST and use the rest of the area for extra internal fuel---you know that in any major air battle since 1998 I believe---no guns have been fired in the air during a dog fight----.

The days of dog fights are done---. In the days of old---pilots were trained not to run away---now they are---use your weapons and bug out---.

 

and for CAS a podded gatling gun could be used, if required.

 

This article is a must for anyone trying to understand IRST, in today's context.

Secondly, I was reading a Boeing document on IRST for the F-18, when the DoD hadn't selected the IRST21 fuel pod, and it mentioned the same thing. IRST's range exceeds that of the APG-79.

 

ok then thats better. but its only if your going to use a fuel tank often though. in that cast the jf-17 is ideal then.

 

But---then the J10 was being developed at the same time and it had IRST.
