Russians are struggling with 5G technology. At this rate by the time they perfect it and have the plane in numbers, US 6G prototypes would be flying.

If it refers to full thrust, the new Izdeliye 30 engine should provide 17 tons, compared to 14.5 tons for AL-41F-1. The engine’s dry weight is estimated at 1,450 kg (3,200 lb.), compared to 1,600 kg for AL-41F-1. Thanks to glass-fiber plastic inlet guide vanes, the new engine fan is planned to have much a smaller radar cross-section in the front view.


If what he says is true than Iz 30 should have a TW ratio of pretty close to 12:1 ...Compare that of AL-31FP on MKI with T:W ratio of 8:1 .

Tests of combat aircraft "in the figure" will help to reduce the number of flights almost twice - UAC

Gelendzhik. 6 September. Interfax-AVN - Tests of combat aircraft, including the fifth generation, can be reduced by almost half due to digitalization, Interfax was told in the United Aircraft Corporation (UAC).

"The tests of a modern combat aircraft of 4+ or 5 generations can last from 5 to 10. If, during testing of third- or fourth-generation aircraft, 500-1000 flights were laid, modern aircraft, for example, of the fifth generation, should commit up to 5,000 sorties to polygons, before the product will be adopted, "- said the representative of the UAC.

He noted that modern digital technologies allow to shorten the time, as well as improve the quality and safety of aircraft testing.

"Today, the UAC has started using methods of testing aircraft systems, such as simulations and end-to-end test results, which can almost halve the number of flights for debugging weapons systems, almost a quarter - to assess aerodynamic characteristics," said the representative of the corporation.
According to him, this uses the capabilities of the newest "supercomputers" and takes into account the results of the previous stages of testing - a similar experience in the UAC has already been obtained by testing the designed "in-figure" civil aircraft SSJ-100 and МС-21.

Su-57 (a promising aviation complex of front-line aviation (PAK FA), T-50) is a Russian multi-role fighter of the fifth generation developed by Sukhoi Design Bureau. It is intended for the destruction of all types of air targets in long-range and near-battles, the destruction of enemy's ground, surface targets with the overcoming of enemy air defense systems, the monitoring of airspace at large distances from the base, the destruction of the control system of enemy aircraft operations. The first flight of PAK FA took place on January 29, 2010 in Komsomolsk-on-Amur.

From 6 to 9 September in Gelendzhik is the 12th International Exhibition and Scientific Conference on Hydroaviation - Gidroaviasalon-2018. The exhibition is located on the territory of the Gelendzhik airport and the experimental and experimental base of the Taganrog Aviation Scientific and Technical Complex (TANTK). Beriev. The organizer of the biannual aviation forum is the Ministry of Industry and Trade of the Russian Federation, the United Aircraft Corporation (UAC), the operator of the exhibition is Aviasalon OJSC.

Computer simulation was to reduce JSF/F-35 testing effort. It didnt.
Computer simulation was to reduce Eurofighter testing effort. It didnt.
Computer simulation was to reduce LCA Tejas testing effort. It didnt.
Computer simulation will now reduce PAK-FA testing effort. Carry on Jeeves :rotfl:

There is a recent AWST feature on the challenges of rectifying JSF defects and the weight reduction exercise.
It is a revelation as to the immense tasks involved in perfecting the bird and the huge difficulties in designing and building the stealth bird, the huge engineering skills required ,which are still going on.A pic of the weapons bay shows such a chaotic mess of equipment, wiring, etc., remarked upon by the author, that it is remarkable that the bird is flying entering service.

This gives one an idea of what must be happening with our own LCA, trying to fit in eqpt. to turn the LCA into an M2K. I shudder to think of the time we're going to field the AMCA when global leaders who've built so many different aircraft in their thousands are taking so much time to do do with their latest stealth birds and at what huge cost.
In this context it is worth rememering the Rand study some years ago predicting a v.tough time for US F-22s in the Pacific against superior numbers of Chin Flanker clones, as they would run out of AAMs in dealing with the superior numbers of AAMs carried by the larger numbers of Flankers.

The IAF should operate in the future a balanced force of aircraft including stealth birds in affordable numbers supported by large numbers of heavy, med. and light birds, where the majority should be of the most affordable type that retains credible capability. In all our past wars with Pak, it was the humble Gnats, Hunters, HFs and MIGs
that did the biz. against supposedly superior Sabres, Starfighters and Mirages.Our numerical superiority plus superb training of our pilots enabled us to overcome Pak.

At Kargil we had equivalent - even superior birds in air combat to Pak's F-16s in the form of the MIG-29, why the PAF never dared to swing into action.However, we are losing that numerical superiority advantage today as legacy MIG types in their hundreds are retiring.Added to this is the joint PAF+ PLAAF factor in future conflicts as China starts to pursue a JV mil. strategy against us with the 2.5 front war scenario that we have to plan for, war in both eastern and western theatres and the maritime battle in the IOR.

We will need to possess at least 2 sqds. of FGFAs from 2022+ onwards as China will begin to field the same in Tibet and could even transfer some to Pak on lease if it couldn't afford outright purchase.Therefore , the planned acquisition of the SU-57 outright even if the JV route is abandoned for the current time should be pursued.

There is no weight reduction exercise ongoing. Weight reduction was done back when the program was put into probation by Robert Gates back in the 2010-211 timeframe. This only applied to the F-35B and the program successfully passed the design review for the weight reduction changes at the time . This allowed the next Secretary of Defense to lift the probation in the 2012/13 time-frame. All three F-35 variants currently have a favorable weight margin.

Graham Warwick's article covers all the challenges that they encountered and overcame over the last 15+ years. Remember that the F-35 is no longer in development.It passed that milestone earlier this year. No developmental testing is currently happening to support the SDD phase. They are preparing for follow on development phase now.

t is a revelation as to the immense tasks involved in perfecting the bird and the huge difficulties in designing and building the stealth bird, the huge engineering skills required, which are still going on


There is no "designing" happening at the moment. The F-35 has completed the SDD development test phase i.e. there is no design related issue that the program is working on. There may need to be some subtle design changes for block-4 capability but that is years into the future and will be performed as upgrades as new capability is fielded. Early November is when we will know about the details of Block 4.

A pic of the weapons bay shows such a chaotic mess of equipment, wiring, etc., remarked upon by the author, that it is remarkable that the bird is flying entering service.


What does this mean? There is no "chaotic" mess of equipment inside the weapons bay. The weapons bay, and everything in it has passed both the design reviews and is a frozen design. This is the way the designers intended it to be, and this is the way it will remain. There is some subtle change that will be incorporated on a few F-35Bs that were produced before some of these changes passed their design review but that will be done at the organic depots on those birds. The F-35s bay designs and requirements were strict. 4 BVRAAMs with growth for 2 more (total 6 AMRAAM class missiles), 2000 lb class PGM in both the bays and cruise missiles like the JSM as well. This from a single engine medium sized aircraft with all the sensors and antennas that it also had to house.

^Is that 6 BVR+2PGM+1cruise or 6 BVR/2 PGM/1 Cruise?
If it's the first case then holy shit!!!

No 6 AMRAAM class BVRAAMs and nothing else internal. The mixed load is 2x Strike weapons + 2 x AMRAAMs. Those two strike weapons can be 2 x 2000 lb bombs, 2 x JSOW's, 2 x JSM stand off missiles, 2 x AARGM-ERs ARMs or up to 8 x SDBs.
