Title of the Su-35 has long been understood in the world of aviation. Under this naming since 1992 at international air shows do not show up once upgraded fighters, Su-27M, which were created at the time ordered by Russian Air Force. At the turn of the new millennium, Su-35 fighters participated in the tenders Air Force Korea and Brazil, with the role of aircraft demonstrators were the same machines vypushennye in the first half of the 90th. Over time, it became evident that for the successful promotion of the world market and the competitiveness of modern and promising zabugornom fighter aircraft requires structural modernization, which should affect not only the complex avionics and weapons, and indeed the glider machine, as its power plant. The latter was to provide a substantial increase in resources and service life of a fighter. As a result, by the middle of the first decade of the new century as a whole formed a concept deeply upgraded fighter Su-27, which was retained for the title of the Su-35 (occasionally used the Su-35BM (Big Modernization).
So, after all that is implemented in the design of the new Su-35? In 1-x, the fighter will get an improved airframe with a reinforced structure that will allow to achieve significant growth in the resource aircraft — up to 6000 hours or 30 years of service (up to the first resource control and restoring repair and overhaul increased to 1,500 hours or 10 years of operation). On the aerodynamic configuration it is similar to the Su-27 — unlike the Su-30MKI it will not have the front horizontal tail, with all this in all 3 channels will be implemented-by-wire control, without mechanical wiring. The application of modern management system encompassing the SIC-35, developed by PBMCs "Avionics" and carrying out the functions of several systems at once, previously used in the Su-27 (remote control system, automatic control, limiting signals, air signals, brake control wheel chassis, turning control Front Desk) will increase the piloting and maneuvering ability of a fighter. SIC-35 soon will be making active safety features.
Of the design features of the Su-35 should also note the absence of the usual for the Su-27 of the upper brake flap — its function scamper differentially deflected handlebars direction. Due to the increased take-off weight of the Su-35 reinforced chassis and the front two wheel support is made. In the manufacture of airframe realized radar signature reduction technologies, which provide a reduction of its reflective capabilities in the X-band radio waves in the angular sector 60.
Outside the new Su-35 (T-10BM) closer to ordinary Su-27 than to the former Su-35 (T-10M): it does not have canards, tail prop shortened. The wings of the corresponding applications on the ship's Su-33 with a huge flaperon occupying the entire trailing edge.
Somewhat strengthened airframe, which allows to increment the highest take-off weight of up to 38.800 kg. However, by reducing the weight of the avionics, empty weight has remained fairly constant (16,500 kg).
In addition, the reduced area of the vertical stabilizer, which reduces lung cancer — visibility, reduced volume zakabinnogo cover (thanks to modern avionics and a small sized). Minor configuration undergone canopy pilot.
As applied to the airframe of the Su-35 is appropriate to use the term "gentle treatment of modernization." This is justified by the designers zeal to avoid or minimize the amount of expensive statispytany, as well as a lot of use of the existing standard equipment.
Airframe of the Su-35 will increase the supplies of internal fuel by more than 20% — if he achieves full fuel 11,500 kg compared with 9,400 kg in production Su-27. In addition, the aircraft provided the use of 2-mounted fuel tanks with a capacity of 1800 l, suspended on underwing point. With navesnoymi in store fuel tanks total will reach 14,300 kg. The aircraft is also equipped with a system of in-flight refueling in a "hose-cone" with a sliding bar on the left side of the fuselage head. Rate of pumping fuel when refueling achieves 1100 l / min.
The principal difference from the Su-35 family of aircraft preceded him Su-27 is used in its new power plant over-thrust engines. They are designed to "Saturn" and are known under the title of "117C".
In the design plan, these engines are the most profound development of the AL-31F series with the introduction of technology fifth generation. On their new fan used the 3% increase the diameter (932 mm to 905 mm), the new turbines high pressure and low pressure, brand new digital control system. On the engine, includes the introduction of the nozzle with thrust vector control (as in the AL-31FP). As a result of modernizing thrust motor on a particular mode is increased by 16% — up to 14,500 kgs, at the highest besforsazhny mode, it achieves 8,800 kgs. Compared to today's AL-31F significantly — in 2-2.7 times — increase resource characteristics: TBO increase from 500 to 1000 hours (up to the first resource Polga repair — 1500 h), and appointed — from 1500 to 4000 hrs
According programmke testing and development of "product 117C" was ranked the most experienced 5 engines. The first of them passes 2003 bench tests, and two more have passed flight testing at the power plant flying laboratory — prototype of the Su-27M. Test flights began in March 2004, the first step of the test flight was carried out about 30 flights of flying laboratory with new engines, including 5 — with 2 engines. Then the fourth instance changed the most experienced first reference on the shield, and the fifth was used as a substitute for flight testing.
Conducted bench tests have shown that the introduction of measures have allowed to do much better the engine "117S" in comparison with the layout and exceed the performance requirements specification on thrust and specific fuel consumption. In the branch of "Saturn" on Lytkarirnskom engineering plant (the Capital Region.) In the spring of this year, started the motor test bench resource "117C" in the provision of the first flight of the Su-35. In addition, the shield in Lytkarnno is another engine of this type, which is designed for complex spetsispytany.
Serial production of engines "117S" will be implemented in cooperation Ufa Engine Industrial Association (UMPO Ufa) and "Saturn" (Rybinsk). According to the decision of partners, all work on the engine, "117S" will be divided between the "Saturn" and t
he brain on a parity basis, 50 to 50%.
The first two series engine "product 117S" for flight tests as part of the first prototype of the Su-35 were made by NPO "Saturn" and placed on the KnAAPO first of the year.
Perhaps the most distinguishing feature of the Su-35 will use it a fundamentally new set of on-board equipment. At the base it is management information system (MIS), created for multi-functional, logical, information and program linking avionics systems into a single integrated system, and provides an interface between the crew and equipment. The structure of IMS includes two central digital computer, the means of switching and converting disk imaging and display system that implements the concept of "glass cockpit."
Base information-control field of the cockpit of the Su-35 are two tremendous functional color LCD type MFI-35, functional console with a display integrated microprocessor, a wide angle head-up displays against the windshield IKSH-1M, and the remote control and display.
Operational indicators MFI-35 with a display integrated microprocessor have a size 9 × 12-inch (diagonal — 15 inches) and resolution 1400 × 1050 pixels. They are designed to receive, process and display in multi mode
graphic, alphanumeric and symbol disk imaging, disk imaging display television from onboard sensors television overlay on her character alphanumeric sequence and synthesized disk imaging, as the formation and delivery of video in digital form in video recording. The function controller with an integrated microprocessor designed a display for displaying the correct info and issuing commands by pressing the buttons on the frame at all steps of the flight. Reflex LED Aviation IKSH-1M with an integrated microprocessor designed to provide observations on the background zakabinnogo place collimator image disk imaging) produced in accordance with the control signals. It has a field of view of 20 × 30.
Management of the onboard equipment, systems and weapons in the modern cockpit of the Su-35 is provided by the switches and buttons on the handle control plane and the control levers of the engine, frame and push the operational indicators. So Makar, the aircraft implemented the concept HOTAS. Developing indicators and other avionics systems of Su-35 provides Ramenskoye Instrument Design Bureau and other businesses P W D "Tekhnokompleks."
Weapons control system
Base weapons control system of the Su-35 is brand new radar control system (RCS) with a phased array "Irbis-E", the owner of the unique features of this day for target detection range. It is developed by JSC "Scientific-Research Institute of Instrument. V.V.Tihomirova "(NIIP) as the future development of RCS Bars ╚ ╩, used in the Su-30MKI and Su-30MKM, and is designed as a functional X-band radar with a passive phased array with a diameter of 900 mm, placed with on a two-level Electrical hydraulic (azimuth and tilt), curb promising computer system with digital computer ╚ Solo 35 ╩. The antenna device scans for electrical beam steering in azimuth and elevation in more than 60 sectors gadusov. In addition, the two-stage Electrical hydraulic mechanical pre-war rachivaet antenna in azimuth angle of 60 degrees, and the slope at an angle of 120 degrees. Because of this the greatest angle of the beam in azimuth differences in electrical control and mechanical additional turn the antenna rises to 120 degrees.
RCS "Irbis-E" to detect and accompany up to 30 air targets, while maintaining the continuity of the review sites, to conduct simultaneous firing of up to eight air targets. The complex provides detection, selection and tracking of up to four ground targets in several mapping modes with varying degrees of resolution at a range of up to 400 km, while maintaining control over its air space.
Aerial targets with GO 3 m2 on a collision course RCS "Irbis-E" is able to detect at a distance of 350-400 km (within the boundaries of the field of view 100 grad.2). This is a unique figure in modern aviation radar stations. In the wider field of view (300 grad.2) such purposes are guaranteed to show up at a distance of 200 km in the frontal hemisphere (in the face of land — up to 170 km) and 80 km in the rear hemisphere (up to 50 km on the background of the land). "Sverhmalozametnye" goal with GO 0.01 m2 detected "Irbis" at ranges up to 90 km.
Detection range of ground (surface) targets are as follows: for the purpose of "aircraft carrier" (EOC 50,000 m2) — 400 km, "railway bridge" (1000 m2) — 150-200 km, "boat" (200 m2) — 100-120 km, "installation of tactical missiles" and "tank group" (30 m2) — 60-70 km.
As a logical extension of the "Leopard" RCS "Irbis" so Makarov has significantly more highest property: expanded (more than twice) operating frequency band, increased from 70 to 120 "area for the detection and tracking of air targets in azimuth, substantially (by 2-2.5 times) increased range of actions, improved noise imm
unity, etc. According to these indicators, "Irbis" is at zabugornyh the latest developments in this field, outperforming most of the American and European radar with passive and active phased array.
Development of RCS "Irbis" is in NIIP from 2004 to the time experienced the true standards of bench tests were required, and the first of them is set aboard a flying laboratory Su-30MK2 ╧ 503 and is undergoing flight tests. The first flight of the flying laboratory with the inclusion of "Irbis" in LII. MM Gromov took first this year and showed the highest properties of modern radar in the "air-to-surface". In April, a flying laboratory was relocated to Ahtubinsk for a comprehensive flight testing the latest radar. The main objective of the first step test "Irbis" on the board is to develop new computational tools, evaluation of new modes of operation, the proof of settlement features detection range. This step tests is planned to finish by the end of the year.
Meanwhile NIIP together with the serial Municipal Ryazan Instrument Plant is preparing the first regular sets "Irbis" for installation on the experienced Su-35. Two radars are prepared for placing on the board of the second and fourth copies of the new fighter. The works must be carried out later this year.
Optical-location station OLS-35
Another modern weapons control subsystem of the Su-35 is the optical-location station OLS-35, combining the warmth of the inside-finder, laser rangefinder, pointer and a television channel. The use of modern electronic components, new algorithms and software cause an advantage over RL-35 RL other aircraft Su-27 and Su-30 in range and accuracy acts as reliability. The field of view, detection and automatic tracking optical-location station is 90 "in azimuth and -15 … +60" in elevation. Aerial target detection range of finders in the front hemisphere is more than 50 km away, in the back — more than 90 km. The laser range finder to determine the distance of aerial target range at up to 20 km away and the ground — up to 30 km. accuracy of 5 m
In addition, to ensure the effective implementation of the combat in the "air-to-surface" of the aircraft can be fitted with attachments optoelectronic container — a laser-sighting of a television station that provides detection, tracking, identification and laser-range illumination of ground targets. With it, namely, guided aerial bombs can be used with laser guidance.
The development of integrated and mounted electro-optical systems that can be used on the Su-35, are two companies — Capital Precision Instrument Research Institute (NII PP similar systems are already in use on naval fighter M and G-29 K / KUB created by PC-to-╚ , MiG ╩ for the Indian Navy and are scheduled to be installed on a promising fighter, the MiG-35) and the Ural Optical and Mechanical Plant. ES Yalamov (optical and radar stations UOMZ are commonly used on aircraft of the Su-27 and MiG-29).
In the middle of other new avionics systems of Su-35 — modern navigation and radio communication equipment and systems, providing group acts fighters also highly complex electronic countermeasures, which structure and certain equipment or by other means of interference can be determined by the customer.
Total for placing weapons used 10 knots outer suspension. Another two end wing assembly involved for containers EW. In the arms of the Su-35, besides the already recognizable missiles "air-to-air" medium-range R-27ER1 (8 pcs.), P-and R-27ET1 27EP1 (4 ea.), RVV-AE (up to 12 pcs., including paired suspension 4 missiles under the fuselage) and close combat missile R-73E (6 pcs.), will include five new long-range missile. The range of guided missile air-to-surface tactical missiles includes 6-29TE X or X-29L, 6 and anti protivoradiolokatsnonnyh Kh-31A and Kh-31P, 5 new long-range anti-ship missile Kh-59MK, and new items: 5 anti-radar missiles extended range of the type X-58USHE, three long-range missile systems "Club" ("Caliber-A") and a languid long-range anti-ship missile like "Yakhont". Among the use of adjustable bombs — up to eight bombs KAB-500Kr (OD) with television self, new KAB-500S-E satellite guidance system, and up to 3 kg of bombs caliber 1500 — KAB-1500Kr or KAB-1500L F with television or laser guidance. According to the nomenclature Bomber and unguided missiles Su-35 as a whole is different from the current Su-30MK, but in the future it will be able to apply the improved and new models bombs caliber 500 and 250 kg and rockets caliber 80, 122 and 266/420 mm in including with laser correction. Maximum weight of the payload of the Su-35 is 8,000 kg, it stirred on 12 hardpoints.
For more information,
First flight model of the Su-35 is assembled on KnAAPO hundred percent by August 2007 Recently the MAKS-2007 transport aircraft An-124 "Ruslan", he was brought to Moscow on LII airfield. MM Gromov in Zhukovsky, where, after a demonstration at the air show will last graduating under ground tests prior to flight testing. First flight it must be held, most recently, the lead test pilot named Yuri Vashuk aircraft. Following the first model to build on KnAAPO are two more experienced Su-35 (second and fourth experienced instances), who will join the test program there during the second half of 2007 — beginning of 2008.
In parallel to the tests involving multiple flying laboratories made on the basis of various modifications of the Su-27. On a flying laboratory Su-30MK2 "worked through 503 brand new radar" Irbis-E "and a brand new optical-location station, on a flying laboratory Su-27M ╧ 710 — new engines" 1I7C ", a flying laboratory Su-27M — brand new all-encompassing management system KSU-35, etc. Test flights on flying laboratories programmke Su-35 makes test pilots "Sukhoi" Yuri Vashuk, Sergei Bogdan, Sergei Kostin, etc. It is expected that the creation and delivery of a batch of Su-35 customers can begin in 2009 and continue straight to market a fighter fifth generation. The aircraft is also included in the Municipal weapons program from the period up to 2015, which is scheduled deliveries of Su-35 Russian Air Force.
