      On PD-14 Engine

      Compared with the American PD-14 engine is a turbofan engine with a bypass ratio of 8.5 (at 12 PW1400G stated). According to the CEO of the Permian enterprise "Aircraft Engine" Alexander Inozemetsva, which is responsible for the development of the engine, the fan technology with gear "is a very advanced technology", and its indicators are very promising for the engine such dimension. PD-14 parameters were selected based on the task of achieving the lowest operating costs.

      The gas generator consists of eight stages of the compressor and a compression ratio of 17, ramjet combustion chamber and a two-stage turbine. Key technologies PD-14 - use of wide hollow blades of titanium. The same blade used in the six stages of low pressure turbine. Hollow blades can reduce the weight of 500 kg, compared with the conventional blades, and the total engine weight is 3.8 tons. Engine-plant in Ufa (UMPO) has developed a proprietary technology that is patented and allows to produce blades. According to Alexander Inozemetseva, PW1400G engine, fuel consumption will be 1% higher, but due to its weight and its more modest dimensions under the wing of the MS-21, our engine will be 0.5-0.7% better.

      The dimensions of the gas generator are selected based on the idea of developing the engine family. In the future, based on PD-14 the whole gamut of the engine thrust will be developed from 9 to 18 tons. Cold part PD-14 consists of a combustion chamber, a high-pressure three-stage compressor and low pressure turbine with six stages. Nacelle is short and consists of composite materials by 65%. October 30, 2015 the prototype PD-14 began flight tests on a flying laboratory IL-76LL. PD-14 should be installed on the first MS-21-300, which will begin flight tests at the end of June 2018. First modification of MS-21-300 on the seat 163 (a two-class layout) has received the most orders, and by the developed first. Then it will be developed on a shortened version of the 5.5 meter MS-21-200, which will be designed for 132 passengers. Today it is all available versions of the aircraft, which offers "Irkut". The final decision with regard to MS-21-400 modifications in the near future will not be accepted. The "Irkut" working on this marketing department.

          Was going through some MOD photos- small, but it seems like Ka-52s @ Crimea already have Vihr in service.

Haha... Well, one does not have to resort to hypotheticals in this case, or even leave the Baltic and the Russian coast: Every time the Russians fly some poor old unarmed An-26 prop on a regular ferry flight to Kaliningrad and it gets intercepted by a ton of NATO jet fighters along the way you still get huge headlines about how "aggressive" the Russians are etc. It's amazing.

                        And only because of the MC-21 hater on the last page, here's SSJ100 in the special flight squadron:



                        And six SSJ100s in civilian service:



                        Airliners are cool, too, you know. Apparently they're going to fit winglets to the long range versions of the SSJ soon enough, finally killing off that (highly ignorant) meme about how the SSJ is just god awful because it has no cool winglets.

                        And just as a lil bonus, trip report on a Sukhoi SSJ flying for Brussels Airlines, from Berlin, Germany to Brussels, Belgium:



                        Not awfully eventful, but it's a nice, modern and comfy regional jet.

                          But, but Russia has been flying Bears and Tu-160s of the US coast (and other countries) for years...

                          Mind you, it is somewhat incongruous to see B-1B and B-52 over the Baltic Sea, have they any operational or tactical (as opposed to political reasons) reasons being there?

                            Just for the record, I'm not a MC-21 hater, I find all airliners equally mind-numbing. That's why Key Publishing were kind enough to set up a separate forum for the takes-off-flies-in-a-straight-line-then-lands geeks.

                              LOL nope. MiG-31 is a dedicated interceptor a considerably faster than the PAK FA.

                                TR1 or others - the Kopyo pod. What kind of application could it be used for? Would it be more used for scanning ground targets with lets say for a Su-25 or what would you say?

                                  It is multimode, but was designed for Su-25TM primarily to expand the ground attack role.

                                  RuAF has not bought it however, Su-25T/M is dead, and I don't see any reason to think it will be purchased going forward. It is outdated at this point anyways.

                                        The Su-25TM was too expensive and complex for the Russian Air Force needs, especially in the 90s, when funding was an issue. Sukhoi even integrated R-77, which does not make any sense in an assault aircraft.

                                        Kopyo was also integrated in the Fishbed upgrade known as MiG-21-93. It was acquired by India in the late 90s (Bison). Reportetly, US pilots were quite impressed with it (USAF and IAF organised several exercised together).

                                          Su-25TM also handled like it was overloaded and had system immaturity issues in Chechnya AFAIK.
