Su 75 stealth2/11/2024 The leading edge of the Su-75 main wing adopts a medium sweep angle design, the outer edge is horizontal, and the trailing edge is basically perpendicular to the longitudinal axis of the fuselage. ![]() ![]() It has begun to reduce the wing surface and use the engine with vector propulsion to compensate for the mobility problem. The aerodynamic layout of the Su-75 has made some progress compared with the previous Russian fighters. The Checkmate is expected to use a variant of the Saturn AL-41F1 engine used by the Su-57 much as the F-35’s Pratt & Whitney F135 engine derives from the F119 powerplant on the F-22. Product 30 is in the developmental phase. In order to reduce the risk, the aircraft plans to use a 117S engine with a maximum afterburner thrust of 14.5 tons in the flight test phase, and wait until the “Product 30” with a thrust of 18 tons (open afterburner)/14.5-16 tons (conventional) matures. Chinese FC-31 is in direct competition with Su-75. Here we might as well make a simple comparison of the two fighters. Earlier there was news that FC-31 may also be introduced to the international market, so if the Su-75 is mass-produced, there will inevitably be a competitive relationship between the two. The Su-75 and China’s Shenfei FC-31 are basically fighters of the same level. I don’t know who is willing to be the first “guinea pig” this time. In the propaganda film of the aircraft, many potential customers appeared in Vietnam, India, and the UAE. Its market positioning is locked in some third-world countries that are eager to obtain the fifth-generation machine but are shy in the pocket. Unlike the previous Su-57, which was mainly targeted for domestic sales, the Su-75 is an “entry-level” “affordable aircarft” destined for foreign buyers. Top S-21 and Bottom MiG LMFS Fact#4 Lure in foreign buyers From the appearance point of view, with the United States that year to bid JSF project defeated Boeing X-32 is also quite similar, but “lore” of the body seems to be more slender, both in terms of aerodynamic configuration of the intake and so there are no small way The difference. Fact#3 Elements of MiG LMFSįrom a genetic point of view, the Su-75 is a bit like a hybrid of the Sukhoi Bureau’s early LFI S-21 project and the Mi-type LMFS project. A chine beginning on the jet’s nose and inlet become a shallow leading edge root extension (LERX). ![]() The new fighter’s tail arrangement offers reduced radar cross-section-with a lower profile and fewer tail surfaces to harmonize with other aircraft edges-as well as potentially high agility. The YF-23 lost out to the Lockheed Martin F-22 in the Advanced Tactical Fighter competition, and McDonnell Douglas’s loss in the must-win JSF contest was a major factor in the company’s 1996 merger with Boeing. The jet has two canted elevons rather than a standard empennage of stabilizers and elevators, harkening to both the X-32 and McDonnell Douglas’s JSF entrant, as well as to the YF-23 on which McDonnell Douglas was partnered with Northrop. Bottom Su-75Ĭheckmate also seems to have a short, clipped delta wing, which does not extend to the tail again, like the X-32. The images show an aircraft with a large angular chin inlet reminiscent of Boeing’s X-32 contender in the JSF contest ultimately won by Lockheed Martin’s F-35 and also on China’s J-10B.
