The Defense World page said that with this upgrade package alone, the F-15SEs are enough to make the latest version of the Su-30SM1 inferior and slightly better than Russia’s most powerful 4++ generation fighter today. Su-35. American F-15 fighter. According to this source, the Su-30SM1 variant has been focused on modernizing the avionics system as well as adding modern weapons to help it have the same combat power as the Su-35S. So how is the strength of the Su-30SM1 when compared to an opponent from across the ocean that is the US-made F-15SE because both are in the line of heavyweight air superiority fighters with 2 seats. ? The US newspaper puts the situation that once a direct confrontation occurs between these two fighters, will the bigger victory belong to the Russian fighter or the American fighter? First, the strength of these two heavy fighters and always decisive is long-range air combat. While the Su-30SM1 almost retains the hardware components such as the passive phased array radar BARS N001M, with only software upgrades and a faster processor, on the F-15SE is the AN/APG-82 radar belonging to the F-15SE. Active scanning mode (AESA) has greater accuracy, long range and reliability. The biggest advantage of active phased array radar is its ability to jump frequencies very quickly in a very short time, making it impossible for the enemy to take appropriate electronic countermeasures. The radar reflection area of ​​the F-15SE is very small because it is covered with stealth paint and puts all the weapons in the compartment, making it close to the 5th generation fighter. As for the Su-30SM, it has no improvement. No progress in this area, the RCS is too large with the addition of a pair of nose wings, making it possible for it to be detected in advance by the F-15SE from a great distance and launched a missile to destroy. The Su-30SM1 uses an AL-31FN turbojet engine with a thrust of 12,500 kgs each, while the Silent Eagle is two F110 engines providing a thrust of 13,150 kgs. The maximum speed of the Russian fighter is Mach 2, while in the F-15SE this figure is Mach 2.5+. Russian fighters still can only carry 8 tons of weapons, much inferior to the F-15SE, if taking advantage of the external mount, the maximum capacity of the US fighter is up to 10.4 tons. Part of the above advantage lies in the higher durability of the US fighter’s fuselage, which is also reflected in the F-15’s critical flight hours of 8,000 hours, while the Su-30 is still only 3,000 hours. The only way that can make the Su-30SM1 gain an advantage over the F-15SE is to pull it into a short-range air battle, at which point the 2-way thrust vector control engine and the nose help the Su-30SM1 take the position. better mind. But Russia also needs to watch out for short-range air-to-air missiles with a “lock on target after launch” mode of US fighters because this weapon will make the advantage of mobility disappear.

“However, it is still too early to announce the modernization of the Su-57”, said Major General Vladimir Popov, member of the Expert Council of the movement “Strong Russia”, Honored Military Pilot. launched and added, so far only 3 squadrons are flying this new generation fighter. “Here, we are most likely talking about the completion of the second-stage engines. By the end of the year they are expected to enter series production with characteristics that are true to the standards of the 5th generation aircraft.” “Today, the Su-57 flies on the AL-41F1S for 4+ generation fighters, despite its high maneuverability thanks to thrust vector control, a new engine has been produced for it, went through testing and the certification was practically passed,” Popov said in an interview with PolitExpert. The upgraded version of the Su-57 is most likely just a second-stage engine integration Now the central question regarding when to put the new engine into production is decided. Boris Popov suggests that Minister Manturov is most likely alluding to this when talking about the modernization of the Su-57. Phase two engines have been included in the project, but their creation is being delayed. “It has to do with economic issues at home and abroad, especially when Western rivals have come a long way. But now this period is over. We are completely independent. production, testing new engines and getting ready for mass production,” Major General Popov explained. “Currently in practice, operational experience is being gathered when the characteristics of the aircraft are confirmed,” emphasized Popov. “It’s not the test engineers that prepare the aircraft, but the technical staff who work directly in the unit. This is like another human quality. In this case, some nuances emerge, those New processes are being approved, parts or even systems are changing,” said the honorary pilot. “Two years have passed since these aircraft entered service with Air Force units. There have been a number of minor changes that need to be made to the structure. This is also a type of modernization for the Air Force. for the Su-57”, Major General Vladimir Popov concluded.

Engine problems caused China’s J-20 production to be delayed. Photo: SCMP The South China Morning Post (Hong Kong, China) reported that the country has developed a new coating material for the engine, contributing to solving technical flaws and increasing the thrust of the engine. The new coating material was designed by Yuanke Energy-saving and Environmental Technology Development Co., Ltd. in Hebei Province. This material can withstand temperatures of 1,800 degrees Celsius and helps protect the engine from the risk of corrosion while ensuring higher power. The current widely used military aircraft engine in China is the WS-10, which can withstand a temperature of about 1,470 degrees Celsius and the improvement can make a significant contribution to increasing the engine’s output power. . The propeller has long been considered the “Achilles heel” of China’s military aircraft engine development program. An obvious example is the delay in the development of a new engine that slows down the production of China’s fifth-generation stealth fighter J-20. Chinese scientists have spent years trying to get the WS-15 engine designed for the J-20 to work, but still have problems with the propellers that constantly heat up at high speeds. As a result, the Chinese Air Force is forced to use Russian-made engines or an improved version of the WS-10. Both of these engines are said to reduce the combat and stealth capabilities of the fighter. The new coating material consists of a fullerene, a ball-shaped carbon molecule. The manufacturer says the coating has a “2,000-hour lifespan” and is resistant to corrosion. The special thing is that this material can withstand the heat required for the J-20 to operate at its maximum capacity.

Sukhoi’s Su-57 fighter Associated TASS May 26, citing a source in the Russian military aircraft industry, said the above information Sukhoi is a well-known company in the military aircraft manufacturing industry, especially the Su-family fighters and fighters such as Su-27, Su-30, Su-35 and the latest is the Su-57 stealth fighter. . These aircraft are all 2-engine, similar to the MiG family fighters in the Russian air force such as MiG-29, MiG-35… Source of TASS “The Sukhoi company is developing the first single-engine light tactical aircraft in modern Russian history with a take-off weight of up to 18 tons,” said the statement. According to him, the aircraft can reach a maximum flight speed of more than Mach 2. The fighter is distinguished by its super-maneuverability and improved take-off and landing characteristics due to the impact of the propulsion engine. push vector. In early April, it was reported that the Russian Ministry of Defense had approved the final exterior design of a new type of stealth bomber, also known as the “advanced long-range aviation complex” (PAK DA). ). The PAK DA aircraft is being developed by the Tupolev company with the priority of reducing radar reflections and equipping long-range weapons. Sheet Izvestia news: Several features of the PAK DA have been approved after a series of tests to determine the level of radar signal reflection, aerodynamic test results. “Work on the development of the PAK DA program is at the detailed design stage, construction of several prototypes of a promising bomber is underway,” RIA Novosti quoted a source in the Russian military-industrial complex as saying. The source said that the new bomber will be built according to the “flying wing” aerodynamic scheme, with subsonic speed and long flight time. In addition, it will only use internal weapons, including hypersonic missiles. “It is said that this bomber will be able to control groups of unmanned aerial vehicles and therefore be able to use almost any type of air-to-air missile,” the source said. The new bomber is expected to enter service in 2027. It is expected to replace the Tu-95MS turboprop bombers in the Russian Aerospace Forces. Earlier, it was reported that the Russian Defense Ministry was working on a project to build a special unmanned aerial vehicle (UAV) and a control system for it to be able to engage in anti-submarine warfare. Potential platforms for creating such an apparatus are currently being studied, sources in the Russian Defense Ministry told. Izvestia . In the future, there are plans to use heavy drones equipped with anti-submarine weapons. Several devices combine to form a network that can coordinate the search for the enemy. The drones can be launched from airports or from land. They will be controlled from both aboard and in the air, aided by automation capabilities and artificial intelligence elements. These devices can attack the target independently or in combination with the weapons of other anti-submarine weapons.
