The Russian fighter Sukhoi Su-57 is the first fifth generation multi-generation ghost plane in the service of the Russian army, combining hiding, the superior ability to maneuver, flying at ultrasound speeds, with a varied armament that includes the air-to-air-to-air and guided bombs, and is designed to succeed the MiG-29 and the Soo-27 fighters.
Sukhoi Su-57 (in Russian: Сухой Су-57, NATO symbolic name: Felon) is a multi-task fighter with a ghost technology, developed by a company Sukhoi. This plane has emerged from the PAK FA program (Future Air Camalt for Tactical Aviation), which was launched in 1999 as a more modern and less expensive alternative to the Mikoyan 1.42/1.44 project known as MFI. The plane internally bears the T-50 designation. It is considered the first fighter in Russian military service to depend from the start on the ghost technology, and it is the basis for a whole family of hidden combat aircraft.
Su-57 was designed to be a multi-task fighter capable of fighting air fighting and carrying out strikes against land and sea targets, as it combines the capabilities of hiding, super maneuvers, and flying at ultrasound without the need for suburbing (SuperCruise), in addition to advanced flight systems and a large load of weapons. According to American estimates, the plane will be able in the future to carry nuclear armament through a new missile similar to the “Kengal” missile. The MiG-29 and 27-27 aircraft is scheduled to replace the Russian Air Force, as it is also released for export. The first experimental version took place in 2010, but the development path defined long delays due to structural and technical problems, and even the first productive plane of a crash had been subjected to a surrender. However, the first fighter of this model entered the active service of the Russian Space Air Force in December 2020.
Design
Su-57 is classified as a multi-task-generation fifth generation plane and the first operational ghost fighter in the Russian arsenal. Its design combines stealth, the superior ability to maneuver in all axes, a wide interior load that allows great combat flexibility, in addition to advanced sensors, including active phase matrix radar, with electronic integration that raises the level of automation.
In its development, Sukhoi’s office relied on the American F-22 RAPTOR as a preliminary model of the concept of super-maneuvering album Sukhoi saw that the F-22 design is not suitable as a multi-task-task-fighter due to its great focus on the air-to-air missiles at the expense of the offensive load.
The structure of the plane is characterized by a wide body integrated with the wings, and separated two engines, as well as horizontal and vertical budgets fully animated, with the head budgets to lower the radar fingerprint. Its wings are semi -perverted with moving surfaces, including junaits and flaberons. The directed payment and the extensions of the front roots of the wings (LERX) increases the air instability and thus the ability to maneuver. These extensions contain Levcon for control, which allows rapid recovery after the lifting stops even with the disrupted payment. As for the air braking, it is done by moving the wings up and lobrons down with the deviation of the vertical budgets inside to increase the resistance.
Its structure consists of a large percentage of aluminum alloys (40.5-44.5%) and tantinium (18.6%), as well as a wide use of vehicles that make up about 22-26% of structural weight and approximately 70% of the outer surface, which reduces weight and enhances the ghost.
The plane includes major internal weapons warehouses along the body between the engines to carry large munitions, in addition to smaller side rooms. This design maintains the flow of shape and reduces the radar fingerprint compared to the external suspension.
Dynamic, Su-57 has a high degree of fixed instability in the axis of height and width, an advanced flight control system (KSU-50) and oblique guided actions, which gives it a huge maneuvering ability in all directions. You can carry out sharp maneuvers such as Cobra Bogachov and “bell”, and even flat rotation with slight loss of height. Its maximum speed amounts to 2 Mach, and you can fly at a continuous ultrasound at 1.3 Mach, with an operational range exceeding 1500 km at an ultrasound speed, more than twice the range of S-27, with the possibility of increasing the range by refueling atmosphere.
Ghost
Being the first Russian fighter designed with a focus on hiding, Soo-57 uses several means to reduce the radar fingerprint, starting with the design of the edges and corners to reduce the wave reversal, through the storage of weapons internally, hiding the antennas, and covering surfaces with radar waves (RAM). Infrared search sensor is also treated so that it can be folded and hidden to reduce the fingerprint. Air corridors are covered with materials with curves that hide motor facades, in addition to a barbecue network in front of the air compressor.
The cockpit is covered with a thin layer of metal oxides that absorb waves and reduce its radar reflection by 30%, while protecting the pilot from UV and heat. According to the patent, Sukhoi, the radar section of the plane decreased to about 0.1-1 m² compared to 10-15 m² in Su-27. However, the hidden feature remains concentrated in the foreground more than the rear, unlike F-22 and F-35 fighters that have a wider ghost treatment than all angles.
Despite these technologies, the plane remains discovered by low -frequency radars, even if its accuracy is limited. Some experimental models have been criticized due to the poor external finishing, the clarity of the screws and the gaps in the body, which affected its image in the air exhibitions. Its actual radar mark is estimated between 0.1 and 0.5 m², compared to 0.005 m² for F-35 and 0.0005 m² for F-22.
Engines
Su-57 works with two turbochargers of the AL-41F1 developer for the AL-31, with a payment capacity of 14.5 tons in the subsequent burning, and 15 tons in emergency situations. These engines are characterized by full digital control (Fadec) integrated with the aviation system, in addition to oblique motivations that allow control and rotation control.
The Soo-57M chained version is scheduled to provide the AL51F-1 (IZDELIYE 30) engines in the middle of the current decade, with a higher payment capacity of up to 17 tons with improvement in reliability and reduce the thermal and radar fingerprint by designing new flat nozzles.
Reinforcing
The aircraft includes main internal warehouses with a length of 4.4 m and side wars, equipped with borders to launch a medium-range J-77M R-77M units, and R-74M2 missiles in the side rooms, with the development of a new short-range short-range missile. You can also carry long-range missiles such as Izdeliye 810, derived from R-37M.
For wild and marine strikes, they can carry KAB-250 and Kab-500 bombs, air-38m air-to-ground missiles, anti-ship missiles, KH-35U, anti-radar missiles, KH-58OSHK, and KH-69 Cruise missiles. In the event that there is no need to hide, it can use 6 external suspension points to carry most of the Russian tactical weapons arsenal. American estimates indicate that it will be able to carry a mini -nuclear missile similar to the “Kengal” missile inside its wages.
It was also provided with an internal 30 mm inner GSH-30-1 with 150 rounds, with an effective range of 800 meters against air targets and 1,800 meters against ground targets.
