It reads as "specific thrust" at least once on the site according to Chrome translator. I suspect its a product of an ignorant and careless journalist.

In early 2010, the air first flew the prototype aircraft T-50. Russian multi-role fighter of the fifth generation, developed by OKB imeni P. O. Sukhoi within the framework of the project "PAK FA" (Promising aviation complex tactical aviation), now is called su-57.
In the Central Aerohydrodynamic Institute named after Professor N. E. Zhukovsky new aircraft started to be developed in the framework of scientific research in 1999. Professionals leading center of aviation science in cooperation with the Sukhoi design Bureau was to create a fighter with a number of unique features that have properties, the implementation of which are mutually contradictory. It was necessary to develop aircraft system with functions of fighter, interceptor and attack aircraft. The high combat effectiveness of the PAK FA should be provided with technical solutions in the field of aerodynamic layout, stability and controllability, control systems, propulsion, radar and infrared visibility, avionics and weapons.
Together with employees of the Sukhoi design Bureau and TSAGI scientists have developed the aerodynamic shape of the aircraft that meets the requirements of the fifth generation fighter. Were created not having analogues in the world adjustable stealth intake, which ensures steady operation of the engine on all flight modes. The specialists of the Institute developed a control system for maneuvering the aircraft is statically unstable in the lateral and longitudinal control channels. Ensuring the strength of the airframe with the widespread use of new and composite materials is another challenge that scientists TSAGI has successfully solved. The result was requirements met to the weighted design parameters of the aviation system, the weight of perfection of the aircraft. In a short time carried out work in the areas of safety from flutter, aeroelasticity, design and shimmy of the wheels.
Specialists of the Institute conducted a unique research design the layout of a fighter. In wind tunnels of TSAGI were investigated 28 different models of aircraft; the total number of trials exceeded 32 thousand. Successfully completed testing of new materials and design elements.
After the first flight of the prototype studies for improvement of flight of the machine continued. So, over the next nine years in TSAGI refined the aerodynamic characteristics of the complex were compared with the results of flight tests, worked out the safety of the new aircraft armament. In the process of preparing and conducting flight tests were carried out frequency of tests all created for this aircraft.

Can any one in simple English help us understand based on what TSAGI said about PAK-FA layout , Unstable aerodynamic characteristics etc
How is this design different from Eurofighter , Rafale or F-22 Design approach. Any key differentiating factor and how PAK-FA could be better or not so better compared to these designs ?
It was reported about plans to bring the Su-57 to the export market - does it have potential buyers in the countries of Southeast Asia? How would you generally evaluate the export prospects of the Su-57? Will he be able to withstand competition with fifth-generation American fighters?
- First of all, we are focused on meeting the needs of the Ministry of Defense. At the same time, the fifth-generation Russian combat aircraft has outstanding characteristics, and this makes it possible to consider export prospects in the future. For example, we are open to working with India on this program. India is traditionally the largest partner of Russia in the aircraft industry. This trend should continue in the future.
As for competition, when acquiring such weapons, not only the price or individual characteristics of each particular aircraft are considered. Although these are very important parameters, we have something to offer here. Nevertheless, one of the most important circumstances in the arms market is the level of confidence on the part of the buyer to the supplier. In this regard, Russia is pursuing a very consistent and pragmatic policy, not trying to connect unrelated things, without setting itself the task of influencing other countries through sanctions or some other similar measures.

"If we speak about the Su-57 program, we are today at the stage of manufacturing the first serial panes. In 2018, we completed the manufacture and the delivery of a batch of prototype planes that are now undergoing trials. Under the existing contract with the Defense Ministry, we have two planes in the production process, with the timeframe for the delivery of the first aircraft in 2019 and the second plane in 2020," the Sukhoi deputy chief executive said.
"I am confident that we will cope with the task and the first serial-produced plane will be delivered this year," he added.

Hopefull it's a monkey version
It would be truly hilarious if Chinese grabbed an order for it now after Indians have been dragging their asses and been little twats about it

It would be even more interesting if Pakistan order them. That would be a real pain in the ass for India.
Well, the Turkish case may have looked far fetched some time ago but US congress is looking seriously into blocking the transfer, Erdogan is challenging them to cut the crap and finally expel Turkey from the program so who knows. Turkey has lots of Western tech and may provide the avionics for the plane, they do AESAs, mission computers and many many other things, they could customize the plane almost completely. Best thing would be to help them develop the engines on their own, in the end Rolls Royce may not be the most reliable partner for the engines of the TF-X either and the Izd. 30 is too advanced IMO to be given away.GarryB wrote:They could tailor the model to the customer... in fact some customers might want foreign products in their aircraft... why not... a chance for Russia to get their hands on foreign hardware and have a play while integrating it... never hurts to look.
For a country like Turkey they could offer to let Turkey make a lot of the components they are not ready to export yet... hell they could probably make quite a few bits and pieces for other export sales too.

MOSCOW, March 29 - RIA News. A promising front-line aviation complex (PAK FA) already has an export passport, the government is considering a document due to the name change from T-50 to Su-57, an aviation industry source told RIA Novosti.
Earlier, Janes’s publication, citing Viktor Kladov, director of international cooperation and regional policy at Rostec, reported that Rostec and United Aircraft Building Corporation (UAC) had transferred to the Russian government all the necessary documents for obtaining permission to export a fifth-generation fighter Su- 57E. According to the newspaper, the decision may be taken by the Russian leadership in the coming weeks.
“The PAK FA already has an export passport. Currently, the government is considering a document due to the change of the name of the complex from T-50 to Su-57,” the agency’s source said.
Su-57 (formerly PAK FA, T-50) is a fifth-generation Russian fighter designed to destroy all types of air, ground and surface targets. First flew in 2010, the first production aircraft to be transferred to the Russian Aerospace System in 2019.
