Today we are going to talk about a fighter jet called Sukhoi Su-57. This is a Russian fighter jet. This is a stealth, single-seat, twin-engine multirole fifth-generation jet fighter and has been developed since 2002 for air superiority and attack performance. So let us gather a little more information about Sukhoi Su-57.
Sukhoi Su-57 Sukhoi's internal name is T-50. The SU-55 is planned to be the first aircraft of Russian military service to use stealth technology. The Sukhoi Su-57 is designed to eliminate supercruise, supermaneuverability, stealth and advanced avionics, pay generation fighter jets as well as land and naval defenses. The main purpose of this fighter jet is to make the MiG-29 and SU-27 successful in the Russian Air Force.
The state-of-the-art clean-sheet design engine for the Sukhoi Su-57 currently employs the Isdelii30. The Sukhoi Su-57 is currently in the final stages of development. The Sukhoi Su-57 is expected to be available after the mid-2020s. The Sukhoi Su-57 is expected to have a service life of up to 35 years.
In 1979, the Soviet Union outlined the need for the next fighter jet to enter service in the 1990s. The Sukhoi Su-57 began its program in 1983 to develop technologies for next-generation fighter jets. In 2002, the fighter jet was renamed PFF. Mikoyan was selected as the winner of the competition and led the design of the new aircraft. Deployed in Sukhoi Su-57 with Sukhoi T-50, landing gear in 2007, Russia and India jointly agreed to develop a fifth generation fighter aircraft program for India.
On 22 August 2018, the International Military-Technical Forum and the Russian Ministry of Defense and JSC Sukhoi signed the first agreement for the delivery of two serial SU-57 fighters for this fighter jet. Boris Obnosov, general director of the Tactical Missiles Corporation, reported that an agreement had been signed on the serial manufacture of ammunition for the fighters of this fighter jet and that it was being added.
The first flight of the prototype for this fighter jet has been repeatedly postponed since early 2007 due to uncertain technical issues. The first 47-minute flight of the Sukhoi Su-57, operated by Hero Sergey Bogdan of the Russian Federation, took place at KnAAPO's Dzemgi Airport in the Russian Far East. A total of ten flying and three non-flying prototypes were built for tests and initial combat tests of the Sukhoi Su-57.
The fighter jet is intended to be the fifth pay-generation multirole fighter aircraft and the first operational stealth aircraft for the Russian Air Force. Most of the information on the Sukhoi Su-57 is classified. Sources in the Sukhoi Company and the Ministry of Defense have openly stated that the Sukhoi Su-57 is steely, supermaneuverable, supercruise capable. The composite material for the Sukhoi Su-57 is significantly increased.
This fighter jet has a mixed winged body fuselage. The Sukhoi Su-57 includes all dynamic horizontal and stabilizers. Stabilizers are also found on the inside of the toe to serve as the airbrake of the Sukhoi Su-57. The Sukhoi Su-57's aircraft includes thrust vectoring. This fighter jet has adjustable leading-edge vortex controllers and is designed to control vortices generated by leading edge root extensions.
This fighter jet can streamline and provide high angles of attack behavior, including a thrust vectoring system quick stall recovery. The advanced flight control system and thrust vectoring nozzle make the Sukhoi Su-57 departure-resistant and highly manipulative in both pitch and yaw. The Sukhoi Su-57 is capable of making very high angles of attack maneuvers like Pugachev's Cobra and Bell maneuvers and in which flat rotation is done.
This fighter makes extensive use of the Sukhoi Su-57 joint with 25% of the structural weight of the jet and about 70% of the outer surface. The weapons in this fighter jet are the two tandem main weapons kept in the bay between the engines nestle and the triangular-section bay near the winged base. The Sukhoi Su-57 eliminates internal weapon carrying by pulling from external stores and enables higher performance compared to external carriage and increases stealth.
The aerodynamics and engine of this fighter jet can achieve it on March 2. The Sukhoi Su-57 has significant dynamic advantages over its predecessor generations without superbasic flight. The Sukhoi Su-57 has a supersonic range coupled with high fuel load.
It was recently reported by Izvestia that there were plans to replace the fighter's hydraulic systems with electromechanical drives. The Sukhoi Su-57's combat capability, stealth characteristics, maneuvers and maintenance complexity are found to be reduced. According to the report, the first flight of this fighter jet was scheduled for mid-2022 and tests of the "electric" fighter version could take at least two years.
The fighter jet plans to build the first operational aircraft in the Russian Air Force service to use stealth technology. Like other stealth fighters such as the F-22, the Sukhoi Su-57 has a platform-edge adjustment to reduce its radar cross-section. The front and rear edges of the wings and control surfaces and the seam edges of the skin panels are carefully angled to reduce the number of directions in the Sukhoi Su-57.
The arms are transported internally into the arms bay inside the airframe and the antennas are rearranged from the skin surface to protect the steely shape of these flight jets. Due to the widespread use of polymeric carbon plastic composites, this fighter jet has four times fewer parts than the SU-27. The Sukhoi Su-57 weighs less and is easier to produce in large quantities. The Sukhoi Su-57's aircraft canopy is made of composite materials and 70-90 nm thick metal oxide layers that reduce the cockpit's radar return by up to 30% and protect the pilot from the effects of ultraviolet and thermal radiation.
The design of this fighter jet emphasizes front stealth with RCS-reducing features in the front hemisphere. The shape of the Sukhoi Su-57's after-fuselage is much less optimized for radar stealth than between the F-3. The RCS of this fighter jet has been reduced by thirty times compared to the SU-27, depending on the airframe shape of the production aircraft and the combined effect of the RAM. Sukhoi's patent for the stealth features of this fighter jet cites an average RCS of about 0.1 to 1 m2 compared to the SU-27 of about 10 to 15 m2.
Like other stealth fighters, this fighter jet's low observation measures are mainly effective against high-frequency radar and which are commonly found in other aircraft. The effects of Rayleigh are scattering and resonance means that low-frequency radars operated by weather radar and early warning radar are more likely to detect the Sukhoi Su-57 due to its size.
The initial production of this fighter jet will use chases intermediate engines. The engines of the Sukhoi Su-57 have full authority digital engine control and are integrated into the flight control system to facilitate maneuvering and handling. The cruise speed of this fighter jet will significantly increase the effectiveness of the weapon compared to its predecessor.
For air-to-combat, the fighter jet is expected to have two main weapons in the bay and two short-range missiles in the wing root weapon bay. A new hypersonic missile with features similar to Kh-47M2 Kinzhal ALBM has also been developed for this fighter jet. The main weapon of the Sukhoi Su-57 missile is to have intra-body accommodation and small dimensions to allow it to be carried inside the bay.
The internal 9A1-4071K in this fighter jet is mounted 30 mm autocannon right near the LEVCON root. The cannon housed in the Sukhoi Su-57 can fire blast-fragmentation, incandescent and armor-piercing tracer rounds and is also effective against targets of up to 800 meters for light armored land, marine and air targets and up to 1,800 meters for land targets.
This fighter jet has an in-glass cockpit with two 38 cm main multi-functional LCD displays similar to the adjustment of the Su-35S. The Sukhoi Su-57 has three small control panel displays located around the cockpit. The cockpit of the Sukhoi Su-57 has a wide-angle head-up display. The fighter jet uses an NPP Zvezda K-36D-5 ejection-seats and SOZhE-50 life support system and includes an anti-G and oxygen generating system.
Victor Pryadka said that this fighter jet is capable of flying on its own and can last up to 15G in UAV mode. It was reported by the RIA that one of the prototypes of this fighter jet was tested in "unmanned mode" and in which the pilot played the role of an observer of the aircraft's operations. The Sukhoi Su-57 can be considered a counter-stealth fighter with forward-optimized stealth and infrared sensors.
According to Bill Sweetman, the fighter jet's high operational speed and stand height are combined with its standoff weapons and are designed for fast and fly high flight to intercept enemy support aircraft and can signal its role as an "airborne sniper type". This is backed by Russia's intention to adopt a new R-M air-to-air missile with a range of more than 300 kilometers from the fighter jet's weapons. The newly designed anti-ship weapons will also enable the Sukhoi Su-57 to be introduced as a maritime strike aircraft.
According to Oleg Yevtushenko, executive director of Rostec Corporation, the fighter jet has been tested several thousand times in flight. Test experience of the Sukhoi Su-57 as well as the results of the investigation of the first serial plane crash "used by aircraft developers. A naval version of this fighter jet was proposed for the Shot rum supercarrier.
