ok, lets get back to matters!

So we see the early T-50 prototypes have problems With fuel tank leak.

Its very interesting to read this latest F-35 joint Office report:

The F-35 joint program office expects to begin flight tests with the latest — and nearly final — version of Block 3i software next week and is on track to deliver the completed software load in January in support of Air Force initial operational capability.

F-35 director of engineering Gregg Costabile told Inside the Air Force in a Sept. 10 interview that the program is wrapping up lab and airworthiness testing of the software load and he expects flight tests to begin Sept. 18. He said testing should wrap up pretty quickly and will be followed by one more software modification that incorporates fixes to the fuel system.

“I don’t expect that testing to take very long,” Costabile said. “Once we get 30, 40, 50 hours on it, we’ll have a very good idea about the stability of that system.”

The software should be ready to deliver to the Air Force by the end of January. The JPO confirmed after the interview that developmental flight test is expected to be completed this month, while noting that there may still be additional tests based on initial findings.

The JPO has already been testing 3i in flight, but this next load incorporates mission effectiveness fixes that should improve stability. Costabile said that while the capability differences between the most recent software deliver, Block 2B, and 3i are not significant, the transition was a little more challenging than expected because the two software blocks run on different processors with different hardware architectures. As a result, pilots noticed problems with stability in some subsystems.

Costabile said the root cause of the problem did not take long to identify, which made it easier to develop a fix.

“We knew what we needed to do to fix it,” Brown said. “We expect the first flight test next Friday to prove out the mission effectiveness things we’ve done and then show also that the stability of the system has been improved.”

Meanwhile, the program is also designing a fix to mitigate risk to the aircraft’s fuel tank. During earlier testing, the program found that in certain conditions — namely when a pilot is flying in a scenario in which there is high gravitational force and increasing pressure — the aircraft’s fuel tanks were at risk of a rupture.

The service is working now to design a modification to address that risk, Costabile said, and is currently building the associated hardware and has already purchased long-lead parts. The service will test the software fix before the end of the year, he said, and it should be delivered with the full 3i load in January.

Costabile said the fuel-fix testing is the biggest remaining risk to 3i delivery, but he is fairly confident in the program’s ability to deliver the software on time. “We’re in good shape for Air Force IOC for 3i,” he said.

After 3i is delivered, the program will shift its focus to the next software block, Block 3F, which it has already begun to test. He said the transition from 3i to 3F will be more challenging than the 2B to 3i transition, largely because the difference in capability is so much greater.

“That’s a whole different animal,” Costabile said. — Courtney Albon

Bloddy hell!
How many F-35 jets do they have in the air by now, and they only recently discovered this fault!?
I can understand this problem, the F-35 sports a very large internal fuel tank(s).
And so does the T-50.
But i hope we do not see the very same fuel leak problem for the 12 pre-Production T-50.
Hopefully Sukhoi nails this fix with the latest prototypes.

How the same US Ministery of Defense undersecretary admittede, concurrency production was an absolute madness, just think that before full time production starts there would be more F/35 than F/22 or even F-15E in service.

me am agree.
but also chinabots are also prone to “hey, our economy and technology is rising super fast, that must mean so are our jet engines, radar technology, society, donkey, xyz”.
they dont realize that in some things take time to develop no matter how much money you throw at it.

This is particularly true when we talk about several sectors of aeronautics in which the evolution is incremental and multi faceted, involving several different competences.

Engines are definitively the paramount of this, involving a wide array of knowledge in disciplines like metallurgy, electronics, fuel production, thermodynamics and so on.
So you would need not only a lot of money but both a strong academic sector than a wide body of competent engineers and swilled workers to be up to the task.
And also with this accomplished and all kudos to China for having been able to cope with it anyway, practical experience still definitively matters a lot there.

One time I made a comparison between military technologies and sport describing Stealth as a sort of high or pole jump competition in which you have to reach a set quote in order to get qualification to the final part of the game, after it someone can end first,other second and so on but in every case once you pass the limit you have get it anyway.

Engine ,electronics and so on are instead a sort of long distance run in which when you can made an extra effort to reach the point the other are, out of metaphor making huge investments, but as long as they also keep on keep moving, albeit at a lower pace than you, they would still dominate the game.
Only hope is so to keep on in this extra effort for such a long time to reach them anyway, something that for China would take still almost a pair of decades IMHO.

Well what you describe here is actually the US plan: fall of the Assad government & take over by radical Islam. Israel & the US want a war in the region. Some years back I warned about Libya & Syria being next after Iraq, and every other retard laughed at me. I didn’t read it into a crystal ball, but Gen Wesley Clarke warned us all.

Makes you wonder if they actually do bomb ISIS or if they are bombing someone else 😉

Oh israel is very much willing to when the time is right.

Well, if you are referring to the coalition as a whole I would list it as unfounded assumption, about Turkey and Sunni states…the right contrary.

That would be a ground-breaking capability that not even the mighty AN/ALR-94, SPECTRA etc posses – and hence I think it highly unlikely for the L-150-16M. The L-150-35 on the Su-35S is a more complex and sophisticated piece of kit analogous to the AN/ALR-94, and even it uses Irbis in interferometer LPI mode to target active radar guided missiles.

The next generation AAMs will switch to Ka-band (MMW radar seekers) affording very high resolution for anti-stealth:

AGAT’s Ka-band MMW seeker (centre):

Quite interesting.
So the first two can operate in both X-band than Ku? I suppose the two wavelengths have advantages and disadvantages against different target to be coupled in one seeker.
Or are instead to be used in sequence in the same engagement?:confused:
Fourth is both SARH than active, quite strange combination, while the third is an A2A counterpart of AARGM?
Certainly one can’t accuse russians of lack of innovative thinking..

Actually first Russian plane to super-cruise was the Tu-128 interceptor.

Supercruising at high quote with not any external load was something a quite some planes was able to achieve even in the sixties, just a combination about thrust/weight ratio and clean lines, nothing more, nothing less.
Before stealth it was however something of those impressive but in the end not operatively useful feats.

F-22 is extremely gifted in this field but there is not any secret upa dupa technology behind this, just powerful engines and inner weapon bays.

No. I fear that Sy is now a failed stated. Recent events confirm only an acceleration in this trend. So speaking about the once SyAAF owned planes, one should more discuss it as a thing of the past or include this fact in the title.

Ok, keep in mind however that title is about SyAAF not Syrian Arab Republic, so even if Loyalist zone of control would even be again reduced as soon as their planes will still fight it would not be like you said.

For the rest, no fighting party, with the partial exception of kurds, has ever agreed to a partition of the state in different entities, all of them want it all for themselves.

Pardon my cynicism, but shouldn’t this thread be posted in the Historic section of the forum ?

Actually SyAAF is still making more sorties at week than the whole international coalition in two months, so not at all.
In case you are instead referring to the age of the planes, well it can be a worthy discussion.
Seems however than in their case, close cooperation with ground forces ands closeness to front make wonders in compensating for ( a relative) lack of PGM.
