Doubts on JF17 - What is the life span of JF17.

[knight11]

An aircraft's lifespan is measured not in years but in pressurization cycles. Each time an aircraft is pressurized during flight, its fuselage and wings are stressed. Both are made of large, plate-like parts connected with fasteners and rivets, and over time, cracks develop around the fastener holes due to metal fatigue.

Aircraft lifespan is established by the manufacturer, and is usually based on takeoff and landing cycles. The fuselage is most susceptible to fatigue, but the wings are too, especially on short hauls where an aircraft goes through pressurization cycles every day. Now any claim for the lifescan can be officially done by its manufacturer Chendgu or PAC.

Timely inspection and maintainace can increase the lifespan of the airframe a lot.

Company like Dassault is highly reputated and expert in this field. I read somewhere the same special instrument for carrying out the stress and the structural damage can be used for Mirrage 2000 and Rafale. This I can say because the IAF also seems impressive to its highly availability, maintaince friendly and reliability.

Brother u should separate me from other fan boy. See my point on jf17 is very different . And I believe jf17 is a good option for cash trapped nations since Chinese loan could help them out . But the major point am making is not about avionic upgrades which you are trying to state . Of course old jf17 will be upgraded but the moot point am making is about the airframe which is less than 16 years . Can you confirm it that's all I want . I writing an article an this very specific requirements of buyers . Help me if possible rather calling me a super start or fan boy

oh no no i am not comparing you with the fan boys. I know you have some technical knowledge about this and know what you are talking about. It is just the hatred in your words that is quite obvious and not hard to figure out. Still, i never said anything comparing you to fan boys, did I?

About the question, you asked that there is upgrade planed in 2020 to increase life to 2030, i answered that the only planned upgrade is to bring the earlier planes on par with the new blocks and incorporate the same upgrades in the older planes, have nothing to do with increasing life span. I still think i answered what you asked in that particular post.

As for the help, if you are looking for facts, these are available all over, the life span (REPORTED) of 4000 hrs (that logically will be more then the 16 years you or any SOURCE says but still lets stick with that) is what the is being quoted. Surely we will get to know the details once the first few planes reach the end of there service life and it can be said safely that it leave us with YEARS of wait. Till then, all the facts can and will be twisted.
I wish you luck with the article. Sadly, looking at your posts do not give me much hope of anything realistic or informative coming but still, that was always your choice so i can just wish you luck with that. Furthermore, i love to read those anyhow

And please, i didn't called you a super star.

You check your source properly . Jf17 is a low cost fighter with no takers because of the life time upgrade . In simple term it will cost 50-60 mil over all just to make it fly for another 10 years

Alright, thanks for the heads up!

Kya Hua had i interruped in your technical discussion

 

[danger007]

Since its built in 2000s it doesn't mean it should have more life span than above 2000s fighter . It's all about how much composite involved

Life span of jet depending upon Composites used in its frame, Over hauling, upgrades it's receive, Regular maintenance, etc... certainly you can extend it's life time....

So superstar----what is the life span of a mig 21 or an F7---. As JF 17 is a new aircraft and modular design---it would be around 8 to 10 years more than those.

We keep Mig 21 alive as we are struggling it's replacement...

Nice man nice that you dint . And by the way I think terms of life span of jf17 has changed due to some wired reason ( to find a buyer?) I still remember the days when debate was focused on this very issues . But am sure the involvement of composite materials are too low to achieve 25 years of fatigue and replacement of bad section means replacement of major or entire airframe for jf17 . Do u agree with it ? If no then we all call it a day and go with OEM If yes then our common sense prevailed

Hi,

Some math questions have simple answer even though people may want to put many a twists to it----.

F 16 is a single engine western block aircraft and JF 17 is a single engine eastern blk ( Chinese primarily ) aircraft.

So----one good example of eastern block is the F 7 and the Mig 21----then that is the comparable standard by default---as JF 17 is the newest most single engine from this blk.

So---whatever the life cycle of the F 7 or Mig 21 is--the JF 17 is going to be 8 to 10 years or better---because of newer and better technology and assembly materials available.

Technology is increasing at a pace like never seen before----so the aircraft of this day and age and period will be getting upgrades at a much faster pace than before to decrease the difference in potency with that of the opponents.

As the british brag about their Holland and Holland---americans on the other hand believe in the Remingtons----it is inexpensive---it is reliable---it shoots straight---. So---then certain aspects of technology are a frame of mind----ie---what kind of bang you get for the buck.

Which means----is it worth it to invest in having major parts in composite material or the old is still gold works better for us----.

The other thing---the life span of JF 17 is a ridiculous issue at this time----. What is important is it is flying---it has been integrated with all the needed weapons and electronics---and is ready to fight the today's battle within a few minutes----.

Hi,

It does not work like that---and it is not as simple as that---. It is all a function of technology---.

The thing is that at 25 million dollars a pop do you have a disposable 4th gen technology aircraft JF 17 blk 1-2 or at 30 million dollars a 4.5 gen aircraft JF 17 BLK 3---like a disposable RAZOR blade---.

So---if my 4.5 gen aircraft---a JF 17 BLK 3 is 40% the price of a F 16 BLK 52 or a Grippen NG in todays market----then why do I need an aircraft to last me more than 20 years when at that time this aircraft will be of obsolete technology---which I am not saying that it is---it is less that 1/2 the price of the competition---does the same / similar job.

Then why should I not build myself a new aircraft at that time with the newest technology to last me another 20--25 years from that time when my cost factor is less than half of the competition.

Composite materials or not----Pakistani military procurement has a different mindset as compared to the indian military procurement. For us function is more important at a reasonable cost than show---.

Our F 16 have given us an excellent service over the years without composite material---.

We really don't want to re-invent the wheel---.

So---let us say---at the end of 16 years----I can manufacture a brand new aircraft for around 40 million dollars---a 4.5 gen aircraft----and still I come out ahead of a Grippen NG ( 70 million dollars ) or a F 16 BLK 52 ( 60 million dollars ) that I bought today---and---so then where lies the problem with a 16 years life span.

 

[Thorough Pro]

Actually Tejas can last for 300 years because life diminishes with flying hours

Tejas has a life span of 30 years or 3000 hours..whichever comes first

your Chinese media friends must have said 1.6 years, but being the fucking idiot you are, you thought it was 16, btw all the Block one's inducted so far have already been grounded.

I don't want to disclose the details but I have some friends in Chinese media . Who said life span of jf17 is not more than 16 years due to less composite . Am from the media . Our other correspondent said teas has more composite material than jf17 .

Funny part is that many cash strapped countries are interested in this fighter but they all shown their concern with Chinese authority about the airframe life span . Which is very costly when compared with other second hand f16s which are or will be available in near future



You are totally correct . And is it true by 2020 the current jf17 to undergo major upgrade to to extend their life till 2030 ? Can you please confirm


You are talking about the engine overhaul . Teas airframe can withstand 25-30 years

Brother thank you for calling me a super star but what's your source on your claim ?

What kind of source would you trust? and I think the super star part was more on sarcastic side.. but that's my understanding!

 

[MastanKhan]

Hi,

Why are you Pakistani guys going on the defensive on the life span of the JF 17---. You cannot even discuss your potent frontline aircraft---you guys have no clue how to work the discussion to your advantage---.

 

[OTTOMAN]

That's actually the unit cost but the real saving starts after buying the machine.
Operational cost of thunder is below $2000/hr.
Fighter pilot conversion cost is lowest in industry.
Comprehensive weapons packages available at lowest cost.

Hi,

Thank you for your post---you missed what I was saying----.

 

[Pak47]

Lol, why worry about Jf-17.. The real star is tejas. Breaking life span records while still being rolled on trucks.

Yes JFT has a life of 6 year... It's a crappy jet.. Good option for cash strappe nations .. You should know Atleast induct 8th gen LCA and bring it atleast on par with crappy JFT... (Which by the way is being upgraded to BLKII)

The way you talk sounds like Chinese are selling jf17 the 4th gen jet for charity . High quality but only 25 mil

No need to get emotional here how much composite parts are involved in both tejas and jf17 ? In terms of percentage and how both have sane life span with different composition of composite material ?
