    No Bacon. The Indo-Rus tactical transport would have Turbo Jet engines, highly sweeped back wings(for a transport) etc etc.. in short some crazy high specs.. which most of them originated from .. wait for it.. IAF!!
    It was supposed to replace the An-26/32 for India i think.

    It was to be produced in India after a short Pre-serial production in Russia.. No freakin wonder why the Su-57 is lacking with India at this point! They have the highest arrogance of all Nations when it comes to demands and requirements.
    No wonder how this Tactical Transport never came to be..

      that tactical transport is now called IL-276 and is for post 2020 period now.
      whoe description of Superjet in Mexico.

          http://niiet.ru/goods/tranzmod/gan-development

          niiet is the one producing the GaN modules and amplifiers. This is a page from their website regarding them. Said GaN Transistors are called: ПП9137А. Last year they tested Amplifier УМП2740-10D which gives continuous 10W output. Now mind you, this is probably without cooling since GaN isn't as much as a problem for cooling as GaAS was. And apparently that is what the problems Phazotron faced with their AESA radars that the cooling structure for the MiG-35's are not sufficient for the GaAS modules. This entire time they been working on reducing the GaAS modules in size and overall reducing the temperature let off by these devices.

          What I find interesting about the whole aspect though is that it was no more than a couple of years ago that it was said (I am not sure if it was on this board or not) that GaN cannot be produced in Russia due to lack of specific technologies or needed resources. Now here we are, couple years later and they already have a production going of GaN modules and currently production facility from NIIET (Of Ruselectronics) is expanding to increase production capacity of said GaN modules since they will be used in both military and civilian production.

          The holding company Ruselectronics started producing gallium-nitride (GaN) transistors for the creation of networks 5G and the new generation of radar systems. The prototypes were tested in the composition of the quadcopter, radio stations and apparatus locations of airports and is currently delivered to over 20 businesses to test operation.

          Developer of products made by Voronezh, JSC "research Institute of electronic technology" (part of the holding part of the Concern "Sozvezdie"). The company is currently working on expanding the line of GaN transistors.

            The IAF never asked for the moon. Stop making such a drama. All the IAF wanted was to integrate a turbo fan engine with full FADEC and this was where the PS-90 fell short. Then there were also some rumors about installing a Western engine, most probably a CF6 variant.
            No one ever asked for any turbojet.

            And highly swept wing? Seriously.
            Have a look at Kawasaki C-2 and Embraer KC-390. They don't have swept wings I guess. Their wings are straight. And they also have turboprop and not turbofans.

            And the Su-57 deal is about to be signed. If not within this financial year then in 2018 - 19 period. It's almost a done deal like the one for five S-400 regiments for the airforce.

                  About the Engines, well i should have said "a Jet engine" i guess.

                  But My initial post still stands. This plane sure looks slick! Only problem is.. its a slick paper plane. Go IAF!

                    but I think the Il-112V pics are great news. Isn't this the one India got cold nuts over?
                    No, India got cold curry over the Il-214/MTA. Now that program is dead and has been superseded in Russia by the Il-276, which looks like an Il-76 downsides with two engines.
                    Il-112V will be replacing turboprop Antonovs in Russia, I think they also will offer it to India eventually.

                    The IAF never asked for the moon. Stop making such a drama. All the IAF wanted was to integrate a turbo fan engine with full FADEC and this was where the PS-90 fell short.
                    We know that they couldn't come to an agreement re. requirements for the plane, but the PD-14/PS-90 question is still open. I was under the impression the Indian side wanted the PD-14, but according to Ilyushin:

                    http://bmpd.livejournal.com/2376724.html

                    Russia was ok with PD-14, but India wanted PS-90 levels of thrust, which Ilyshin thought was excessive for the aircraft's size and cargo capacity.
                    Regardless first examples will have PS-90.

                    Not all the shenanigans re. MTA were India related. There was a considerable sum of money laid aside by the Russian gov for the Il-214 that was discovered to have been....sitting around "unused" for several years"....

                        Saab Global Eye came out it was claimed that it can detect stealth targets at extended range presumably due to GaN modules. I don't want to embarrass the person who brought this Russia cant make GaN modules when Russia is making much bigger AWACS with much much better engineering skills. Sweden has put Sony in front of Ericsson. There are countless other firms that Sweden has foreign ownership and help now. even JAS39E engine and components practically imported. A country that is losing more and more industrial and scientific skills all of sudden can make better GaN T/R modules with all the complex software development.

                        However, at the core of the system is a new airborne early warning radar known as Erieye-ER. Housed in the same over-cabin “ski-box” fairing as the previous iterations of the Erieye radar, the S-band Erieye ER employs gallium nitride semiconductor technology to allow more power to be transmitted while providing greater flexibility of operating mode.
                        In developing Erieye-ER Saab looked to extend the range at which low-observable targets can be detected, as such air vehicles are increasingly fielded around the world. “Reclaiming the stealth gap” is how the company describes it, and the GlobalEye is being marketed as the “stealth-killer.”

                            In Russia successfully tested detonation rocket engine
                            Detonation rocket engine tested in Russia, announced on 19 January, Deputy Prime Minister Dmitry Rogozin on his page in Facebook.
                            "Successfully tested a so-called detonation rocket engines, developed in the framework of the program of the advanced research Foundation", quotes the Vice-Premier Interfax-AVN.
                            It is believed that detonation rocket engine is one of the ways of implementing the concept of the so-called hypersonic engine, that is, the creation of hypersonic aircraft, capable through its own engine to reach speeds of 4 to 6 Mach (Mach is the speed of sound).
                            On the first test detonation engine demonstrator wrote in the article sdelanounas.ru/blogs/95367/.

                              For detonation rocket engine it is russian for detonation pulsejet?

                                Judging by the diagram, it's a rotating detonation engine (RDE) and it runs on an internal oxidizer so "rocket" is technically correct.

If you have cooling problem with GaAS chance are you will face even severe problem with GaN. As i outlined before to make use of GaN module for fighter radar. one need like 50-60 KW/Sqm cooling capacity.

                                    Hence why they may be testing throughly a 10W amplifier for GaN cause possibly that's best they can do with current cooling structure in place.

                                      one more thing. That Global Eye radar only become reality due to $1.2b export deal with UAE that include integration on new platform. it shows it is not some huge sum of money that make GaN radar make happen even with ineffective R&D history.

                                        Embedded not just remote cooling is the likely future of GaN RF systems especially at the extreme SWaP optimization requirements as one would expect from a high performance fighter. Demonstrations of early concepts at relatively decent Technology readiness levels have shown up to 7 times the power density of comparable remotely cooled systems..

                                          Well if it can bring the capacity it would be nice. The current liquid cooling technology can do about 155 KW/Sqm. but i wonder if such capacity can be carried by fighter aircraft.
