Many interesting things can be noticed in the video where, the main character, the commander of the air force of a foreign state, talks about the advantages of the fifth generation aircraft and the philosophy of the project. The video contains references to the key features and unique capabilities of the fighter. The project is made to accompany the foreign debut of the fighter, which will happen tomorrow in Dubai. ⚡️ Rostec unveils Checkmate limited edition perfume for the Dubai Airshow 2021 Interestingly, a new promotional video was also released by UAC as part of a pretty aggressive PR campaign that also included the launch of a signature perfume called, just like the jet, “Checkmate”. Meanwhile, simultaneous production of “several prototypes” has already been started by a plant in the city of Komsomolsk-on-Amur, in Russia’s Far East region, according to the official. “The first flight of the fifth-generation fighter Checkmate is planned for 2023, serial production - in 2026,” Yury Slyusar, the general director of the Russian United Aircraft Corporation (UAC), said on Sunday. More detail about the “Checkmate” are being disclosed these days, as the Russian fighter takes part to its first foreign airshow: Dubai Airshow 2021. Cannon containers can be placed in the inner compartments of the aviation complex to destroy ground targets” “In an inconspicuous configuration, the fighter is capable of carrying up to five air-to-air missiles, effectively fighting a numerically superior enemy, and detecting and destroying fifth-generation aircraft in long-range and close combat. “The maximum combat load of the Cheсkmate is 7,400 kilograms, the flight range without external fuel tanks is 2,900 kilometers at speeds up to Mach 1.8, which is one of the best indicators in its class,” says UAC website. The aircraft unveiled at MAKS was a mock up, “better done and certainly more realistic than many we have seen in the past, but certainly not a prototype yet,” we commented back then (full description at this link), however, many interesting details about the development of the “Checkmate” emerged from the media hype the followed the presentation: the lightweight single-engine fighter, possibly designated Su-75 (based on the registration and bort number) is said to be stealth to embed artificial intelligence to be able to operate in a networked environment to carry supercomputer technologies along with AESA radar as well as a wide array of weapons. The official unveiling was preceded by an ad teasing the jet, also pointing to the export profile of the design, suggesting UAE, India, Vietnam and Argentina might be potential customers of the new stealth fighter. That is to say, their stealthiness is worth the difficulty in controlling them.A new interesting clip, released for the presentation of the “Checkmate” 5th generation light tactical aircraft at Dubai Airshow 2021, teases the unmanned version of Russia’s new stealth fighter.Īs already reported in detail here, the Sukhoi “ Checkmate“, Russia’s new 5th generation fighter aircraft design, made its public debut at MAKS 2021 airshow in Zhukovsky, near Moscow in July 2021. Sukhoi obviously decided the downside of ruddervators is worth the upside. Air Force’s Advanced Tactical Fighter competition- they had to invent a new kind of actuator to move the plane’s ruddervators. When Northrop engineers designed the YF-23-the big, weird fighter that lost out to the YF-22 in the U.S. Ruddervators require sophisticated flight-control systems. A whole angled ruddervator moves, pushing the jet’s nose up or down and to one side or the other-and it does so without offering radars on the ground strictly horizontal or vertical surfaces off which to bounce their energy.Ĭheckmate’s ruddervators likely make it stealthier than, say, a MiG-29-but not without a cost. Ruddervators essentially combine both elements while mitigating their observability. The problem is that an airplane needs elevators and rudders. Vertical stabilizers also are radar-reflectors from certain angles relative to the enemy.Įliminate the horizontal and vertical stabilizers and you’ve cut the number of edges and flat surfaces off which radar energy can reflect back to the emitter. Wings and horizontal control surfaces with their straight edges and huge surface areas are a major source of radar reflectivity. Ruddervators can help to reduce the number of highly detectable surfaces on a jet while still affording it good maneuverability.
