The latest multirole Su-30SM2 fighters, after being equipped with AL-41-F1S turbofan engines with afterburner and N035 Irbis-E radar stations, will significantly increase their combat power. Military expert Evgeny Damantsev revealed the technical details of the updated aircraft.
He noted that due to the increase in total afterburner thrust from 25,000 to 29,000 kgf, the fighter will have a higher rate of turn in the pitch plane, as well as longer and more stable energy maneuvering on verticals in close air combat, than with standard AL-31FP engines.
The aircraft's climb rate will increase to 260-265 m/s and will only be slightly inferior to the climb rate of the Su-35S (280 m/s), which is due to the larger midsection due to the larger volume of the two-seater cockpit of the Su-30SM2.
He added that the maximum flight speed near the ground may increase to 1375 km/h, at altitude - up to 2230 km/h. The practical ceiling will increase from 17300 to 18500 m.
The aircraft will also be re-equipped with N011M Bars-R onboard phased array radars to N035 Irbis-E radar stations. They are equipped with powerful microwave magnetrons, providing a peak pulse power of 20 kW and a continuous illumination power of 2 kW, while the Bars-R has 4.5 and 1 kW, respectively.
The energy parameters provide a capture range for accurate auto-tracking of targets with an RCS of 0.01 m² - 80 km, 0.07 m² - about 125 km, with an RCS of 2.5 m² - about 335 km.
In addition, the N035 Irbis-E radar is adapted for the use of R-37M long-range air-to-air missiles. Currently, the first operational Su-30SM2s are already on combat duty and intercepting air targets with these types of missiles.
