Typical stage 2 mods often include: fuel pump upgrades, high flow fuel injectors, Ported and polished head, induction kit, Sports catalyst & performance exhaust, Fast road cam. Fast road cams, that is a cam optimized for everyday driving, will normally push up the bhp and torque throughout the rev band, you could drop a little bottom end bhp but the top end will be higher. Overall the power will be where a typical driver needs it most across the middle third of the rpm range. It's essential to emphasize that our primary goal is to share knowledge rather than seeking profit. VIDEO: Russia flies first Su-57 fitted with new Product 30 engine". FlightGlobal. 5 December 2017.

The rule of thumb is to add 20% to the flow rate when buying an injector, which takes into account injector deterioration and gives a bit of spare capacity should the engine need more fuel. a b "Russia's 5th-generation fighter jet named as Su-57".

The pilot managed to escape unharmed. The aircraft was subsequently written off, and its salvageable parts were cannibalized to finish the sixth "first stage" prototype, which was then given the fifth prototype's bort number and its designation changed from T-50-6-1 to T-50-5R. However, official accounting still considers the two aircraft to be the "same" one. [44]

Even before the first flight of the T-50 prototype, several subsystems were tested on other aircraft for validation and risk reduction; an Su-27M was used to test the AL-41F1 engine on 21 January 2010, while another tested the KSU-50 flight control system. [145] The T-50 prototype conducted its first high speed taxi run on 21 January 2010 and had its maiden flight several days later on 29 January 2010. [38] First supersonic flight occurred on 14 March 2011 at a test range near Komsomolsk-on-Amur. [89]

As of 2022 [update], international sanctions on Russia's defence industries may hamper development of the Su-57, [76] as Russia could not import semiconductors and high-tech machining equipment from the European Union. [77] Potential export sales of Russian products -including military aircraft- also stalled because Russia cannot trade using U.S. dollars. [78] [ needs update] The low end idle will be very lumpy and irregular, you would also be more prone to stall. So on roads this is a serious issue and we've heard from lots of drivers lamenting their decision to add an extreme competition cam profile to their engine. On 24 December 2019, the first serial Su-57 (bort number "01 blue") crashed 110–120km away from the Dzyomgi Airport, Khabarovsk Krai, during the final stage of its factory trials due to a control system malfunction. The pilot ejected and was recovered by helicopter. [242] [243] [244] [245] According to TASS, the test flight took place at an altitude of 8,000 meters when the malfunction occurred, causing the airplane to enter a rapid spiral descent. When all attempts to stabilize the airplane into a horizontal flight using the manual flight control system failed, the pilot ejected at an altitude of 2,000 meters.

The War Zone. 25 March 2020 . Retrieved 26 March 2020. For air-to-air combat, the Su-57 carries four beyond-visual-range missiles in its two main weapons bays and two short-range missiles in the side bays. [111] The primary medium-range missile is the active radar-homing R-77M ( izdeliye 180), an upgraded R-77 variant with AESA seeker, dual-pulse motor, and conventional rear fins. [112] The short-range missile is the infrared-homing ("heat seeking") R-74M2 ( izdeliye 760), an upgraded R-74 variant with reduced cross-section for internal carriage. [110] [113] A clean-sheet design short-range missile designated K-MD ( izdeliye 300) is being developed to eventually replace the R-74M2. [109] For longer ranged applications, the izdeliye 810 missile, a further development of the R-37M, can be carried with two in each main weapons bay.
