Su-30 Flanker-C – Russian 4 generation fighter jet [review]
The Sukhoi Su-30 is a Russian multi-role fighter aircraft based on the two-seat training aircraft Sukhoi Su-27UB, the development of which began in the last years of the Soviet Union.
Sukhoi began developing the Su-30 in the mid-1980s. Even before the Su-27 (“Flanker”) was put into service, further development began. The aim was to create a whole series of aircraft types, which would consist of a long-range interceptor, an air superiority fighter, a tactical fighter-bomber and a multi-purpose fighter. Suchoi referred to this generation as Series 30.
The Su-30, initially also called Su-27PU, should represent the long-range interceptor in this concept. The first prototype flew under the designation T-10PU-5 for the first time on December 30, 1989. The prototype was relatively free of problems, which is why series production began very quickly. The first Su-30 series aircraft flew on April 14, 1992, and this type was put into service that same year. In use, the Su-30 was intended as a supplement to the MiG-31 (“Foxhound”), which should then be used primarily to defend against cruise missiles. The Su-30 was designed to intercept US B-1 and B-52 bombers over the North Pole and the Pacific. With the collapse of the Soviet Union, this concept became obsolete, making the Su-30 “unemployed”. As a result, there was initially only a limited production of Su-30 machines.
As a result, Sukhoi began looking for new tasks for the Su-30 and began converting the Su-30 into a multi-role fighter. The result was the Su-30M, which is primarily intended for fighter-bomber missions. According to this range of tasks, a new combat electronics and a Chaika navigation system were installed instead of the interception radar. At the same time, the rear section of the machine was revised and stabilized to make it more resistant to fire. The Su-30MK was made available for export and repeatedly prevailed against its US American and European competitors on the Asian market.
Despite its size and weight, the Su-30 is capable of remarkable flight performance. This includes the cobra maneuver that has been demonstrated for the first time with a Su-27 and has been famous ever since. Compared to the Su-27, however, the Su-30 achieves a slightly lower climb performance and maximum speed. During maneuvers with very abrupt changes of direction, it loses enormous speed and thus also altitude, which is particularly evident in versions with thrust vector control, which greatly increase the maneuverability of the machine compared to aircraft with conventional engines.
The strength of the Su-30 lies primarily in its high flexibility, as it can be used for almost any type of application. These so-called “multi-role” capabilities are the greatest advantage of the Su-30MK on the world market, as only the F-16 “Fighting Falcon”, F / A-18 “Hornet” and JAS 39 “Gripen” have a similar one have a high degree of flexibility, but without achieving the flight performance of the Su-30. However, this could change with the introduction of the F-35 and the full operational capability of the French Rafale and the Eurofighter “Typhoon”.
The Su-30 has no stealth properties and, due to its size, has a high kerosene consumption, which is compensated for by the large internal tanks, so that the manufacturer has so far not integrated any additional drop-off tanks.
The Su-30 uses the NIIP N001 “Metsch” (also: RPLK-27, NATO code: “Slot Back”) as on-board radar. It was developed for the Su-27 and should have at least the same performance as the American AN / APG-65. However, this was not possible at the time of development, so parts from the existing N019 radar were used (mainly the parabolic antenna and the TS100 processor). Development was completed in March 1983. In the following tests, the range performance was well below expectations. The radar can detect a large bomber for a maximum of 140 km instead of the planned 200 km. Reliability was also extremely low with an MTBF of just five hours. Therefore, the radar was initially not accepted and revised again. The revised radar was introduced in 1991.
The parabolic antenna of the N001 has a diameter of 1.075 m and transmits with an average power of 1 kW in the X-band (8–12 GHz). It belongs to the group of doppler / impulse radars, which is why it also has good look-down / shoot-down capabilities. Large targets can be detected at a distance of 140 km, a target with a radar cross-section of 3 m² over 80 to 100 km, whereby such a target can only be safely tracked from 65 km. The radar also has a TWS mode and can track ten targets at the same time and fight two of them simultaneously. The Chinese version of the Su-30MK2 is equipped with a Schuk-MSE radar, with which up to ten targets can be tracked simultaneously and four can be fought simultaneously.
In the Su-30MKI and its variants, the N011M “Bars” (also: RLSu-30MK) is used as one of the most powerful Russian radar devices for combat aircraft. It is particularly characterized by the PESA antenna, which significantly increases the performance in all relevant parameters. Development began in the early 1990s, with two specially configured Su-27Ms serving as the test platform. During the development, problems arose with the new antenna, which lost massive amounts of power when it was electronically swiveled over 40 °. For this reason, the antenna is now also mechanically aligned horizontally so that scan angles of ± 70 ° are possible, and only ± 40 ° in height due to the lack of mechanical alignment.
The antenna itself has a diameter of one meter, weighs 110 kg and transmits in the X-band. It achieves a pulse power of 4-5 kW and a continuous power of 1.2 kW. The antenna gain is 36 dB, the first side lobe is −25 dB lower, which leads to an average side lobe attenuation of −48 dB. The opening angle is 2.4 °, whereby twelve different beams can be generated. A programmable TS200 processor with a maximum performance of 75 MIPS is used for signal processing. The radar is controlled by three separate processors, which can fall back on a 16 MB RAM.  The complete system weighs 650 kg.
The N011M has several advanced operating modes to effectively combat a wide range of air, sea, and ground targets. These include ground mapping (with Doppler sharpening), TWS (pursuing 15 targets, four of which are fighting simultaneously) and NCTI based on specific properties of rotating fan blades. The location range is around 140 km for a radar cross-section of 1 m².
