Su-57 Aesa Radar - The twin-engine Russian T-50, now known as the Su-57, has an integrated fuselage to accommodate the lower radar section.
As tensions continue in the Middle East between Western-aligned countries and countries such as Afghanistan, Syria and Iran, Russian industry will look to exploit opportunities to export defense equipment to the region. Here in Dubai, the Russian export agency Rosoboronexport (Stand A05, A06) hopes to convince potential buyers that the country is ready to go beyond the capable but expensive innovations and from the Sukhoi Su-27 and Mikoyan MiG-29.

The latest and most advanced types of aircraft - the MiG-35 and Su-35 - have had only moderate success in the commercial market due to the fact that the aircraft have become expensive to acquire and maintain. work out the cost per flight hour. the foundation. the foundation.

"Russian fighters do not offer the same option to operate at a lower cost than their Western counterparts," said a Polish defense analyst. "The old adage 'you buy and pay for fighters by the pound' really applies here. What we [the Polish armed forces] have found is how much it costs to use the MiG-29 against the F -16, like Poland, has both planes and can make some comparisons individually.
Due to these and other reasons, the MiG-35 still has no foreign customers, and now only the Chinese Air Force (PLAAF) and Egypt have received the Su-35, and to a lesser extent. Although the "Super Flanker", as it is sometimes called, is an efficient platform (and also a new aircraft for the Russian Knights demonstration team), it is also very large and heavy and more expensive than the original Su-27 design.
To avoid the trap of inactivity, Russian industry has been working on new generation aircraft designs since the beginning of the last decade. Initially, this effort was focused on developing the American Lockheed Martin F-22A Raptor, originally known as the PAK-FA/T-50. After that, the Russian industry produced images that were used to confirm the aircraft's composition.
The design of the series of aircraft is now known as Su-57 and it has many features of the American fighter - a twin-engine design with a compact body to carry the lower part of the radar. However, the overall size of the aircraft is smaller than the Su-27 or Su-35 designs, but still larger than the MiG-29. Like the predecessor aircraft it is intended to replace, the engines are separated to form a small aerodynamic section with an extended tail of the situational awareness radar between them.

Details of the Su-57 design highlight what one of the critics of the "fifth generation" fighter concept - the U.S. pilot and writer James Stevenson - you have to talk about this. "The 'fifth generation' brand is actually more of a marketing ploy than anything else," he told AIN. "Actually, there are only four aircraft in this category: the F-22, the Chinese J-20, the Su-57 and the F-35 - so two American designs, one Russian and China. If you count the fifth plan. - Shenyang J- 31/FC-31 and its derivatives - you can say that there is a fifth of these types of aircraft in existence today.
"But what you will notice is that they are distinctly different aircraft and in some cases almost unique," he continued. "Being stealthy to some extent is only one aspect of these aircraft that gives them the title of next generation, but in many ways it is the one major characteristic that they all share."
Some observers have pointed out that the Su-57 is the weakest of all these aircraft, while some of its obvious configuration features - such as some notable platform flaws - will give it a major signature. radar than any of the others. . But when it comes to Russia's strategic plans, theft isn't the only important design driver.
Another problem facing the Su-57 centers is that the production costs have risen more than originally estimated, especially when they are still in a very low level of production. At the beginning of the last decade, many thought that India would join as one of the partners of the program, and that other countries using one or more types of Su-27 and Su-30 will be foreign buyers.

None of the developments took place, meaning that the Russian Aerospace Forces (VKS) was the only customer. In addition, neither the NIIP N036 Byelka Active Scanning Electronic Array (AESA) radar nor the fifth-generation izdeliye 30 engine have been put into serial production. Currently, the Su-57s are still fitted with the NIIP N035 Irbis passive array (PESA) radar set and the 117S/AL-41F engine fitted to the Su-35.
The biennial Moscow Aviation and Space Salon (MAKS) is regularly used as a platform for the Russian space sector to beat its collective drum about its achievements. Always taking place in the summer of odd years, it also provides the perfect forum to publicize new initiatives that the industry plans to launch four months later in Dubai.
This scenario was played out again this year with the introduction of a new single-engine fighter concept. While the aircraft's nickname is Checkmate, some analysts also refer to it as the "Su-75", although no official model name is said to exist.
The aircraft presented on July 20 at MAKS was initially described as a "producer", but a report later indicated that the vehicle shown is a non-flying hybrid that is part prototype and part mock-up . The General Manager of United AircraftCorporation (OAK) of Russia, Yuri Slyusar and the chief designer of Sukhoi Design Bureau Aleksei Bulatov gave a brief description of the program at MAKS, but only discussed the basics.

Two industry representatives said the first flight would take place in two years and series production could begin as soon as four years from now, despite doubts at the time from analysts. of the industry who set the start of the meeting seven years from now.
Apparently, the program would meet demand in the international market for a cheaper alternative to Lockheed Martin's F-35. The Russian design team says that Checkmate will cost between 25 and 30 million dollars.
The main obstacle for the inspector may be the lack of funds from the Russian government and no order from the VKS. The program can make the economy possible in that it will be powered by one of the two izdeliye 30 engines that are being tested for the Su-57 program and have the same N036 AESA radar product.
However, VKS once showed little enthusiasm for small single-engine platforms, and many Russian analysts say that hasn't changed much in recent years.
Russia's Su 57 Stealth Fighter Is A Real Threat
"Without Checkmate being a program of record at VKS, it would be difficult to sell to any foreign customer," said a long-time Russian expert in the aviation industry. "However, in the end, they may have to accept this program for the simple reason that the Su-57 will not be able to operate in the numbers necessary to replace the current fleet of fighters of the generation passed away." The N036 Belka (Russian: Белка, literally Squirrel) is an electronically controlled radar system developed by Tikhomirov NIIP for the fifth generation Sukhoi Su-57 fighter.
The radar is part of the Sh121 multifunctional integrated radioelectronic system (MIRES) on board the Su-57. The N036 radar system was developed by the Tikhomirov Institute NIIP and consists of a large nose X-band AESA radar with 1,514 T/R modules, designated N036-1-01, and two radars small X-band AESA with 404 T/ R -modules mounted on the sides of the fuselage previously designated N036B-1-01.
The suite also includes two N036L-1-01 L-band units with wing extensions that are not only used for friend or foe identification, but also for electronic warfare purposes. Computer processing of X- and L-band signals means that system information can be significantly improved. It has the ability to track 60 targets and shoot 16 targets in the air at the same time, or measure four targets on the ground at the same time. The L402 "Himalaya" electronic equipment package (ECM) developed by the KNIRTI Institute uses its arrays and the N036 radar.
In 2012, ground tests of the N036 radar began with the third (T-50-3) and fifth (T-50-5) Su-57 aircraft.
