On this day in 1996, was the first flight of the Su-37 with variable thrust vectoring.
The prototype was built as a prototype fighter aircraft Su-35, under the code T-10M-11. Machine was created jointly by OKB. PO Sukhoi and Yakovlev Design Bureau. AM Cradles (“Saturn”), involving several institutions and other organizations.
The first flight on the T-10M-11 made a test pilot, Hero of Russia Yevgeny Frolov. Already in September 1996, a spectacular aerobatics new Russian fighter managed Frolov, foreign experts were able to see in Farnborough.
Thrust vectoring – the function of the nozzle changes the direction of the expiration of the jet. Can improve the performance characteristics of the aircraft. The pilot of the Su-37 can carry out all the control surfaces deflection and rotary nozzles engine by moving the Centre stick.

May 20, 1977 the first prototype designated T10-1 took off. After an evaluation it was discovered that the T10-1 did not fulfil its requirements for maximum range, and manoeuvrability, and thus proved inferior to its western counterparts. The prototype had aerodynamics problems, engine problems and fuel consumption problems. The second prototype the T10-2 crashed because of a fly-by-wire software failure which resulted in the death of the test pilot. After such disappointing results the from the T10 program Sukhoi seemed to stop T10 development, because there were no more T10 prototypes tested. They didn’t, by 1981 a new design was introduced loosely based on the old T10. The new aircraft was designated T10S which was to become what today is known as the Su27 Flanker. The T10S prototype flew on April 20, 1981. The T10S showed it self to be a masterpiece of engineering having no equal anywhere in the world in range, manoeuvrability, and combat effectiveness.
The Su-27, a Russian fourth-generation single-seat supersonic fighter, is recognised all over the globe as one of the best combat aircraft of the 20th century. Due to its perfect flight performances and operational characteristics, the fighter is rightfully popular with pilots and technicians. Top piloting capabilities of the Su-27 fighter demonstrated during multiple air shows around the world did not leave anyone indifferent. The Su-27 is in the top lines of the aviation record tables of the International
Aircraft Federation. To the date, the Su-27 is a record-holder of 27 world class flight achievements. The Su-27 is the forefather of a combat aircraft family of various functionality, including the Su-27UB trainer, Su-27K ship-borne fighter (Su-33), Su-30 twin-seat interceptor, Su-30MK twin-seat multirole fighter, Su-34 tactical bombers Su-35, Su-37 Su-35BM and other high-manoeuvrability multirole aircraft.

Russian Defense Minister General Sergei Shoigu, along with a high-level delegation, visited the headquarters of BrahMos Aerospace Headquarters in New Delhi today (21.01.2015.)
The Minister was briefed on the progress made by the interface of BrahMos air version with Su-30MKI, with the first test launch expected in March 2015. HAL Nasik Division, which is being mandated to undertake the missile integration work on the Sukhoi, had recently conducted the critical Ground Vibration Test (GVT).
BrahMos Aerospace has been successfully delivering BrahMos weapon systems to the Indian Armed Forces since 2005. The Indian Army has operationalised the supersonic cruise missile system in its arsenal and further orders are in pipeline. Indian Navy has installed the universal weapon system on its destroyers and frigates, and many of its newly-built frontline warships will be fitted with BrahMos in the coming years. The Indian Air Force has also placed orders for land and air-launched version of BrahMos for Su-30MKI aircraft. The 290-km range tactical missile is slated to be test-flown this year in its air-to-ground configuration.
So, what is BRAHMOS:
Brahmos is two stage missile with a solid propellant booster engine as its first stage which brings it to supersonic speed and than gets separated. The liquid ramjet or the second stage then takes the missile closer to 3 Mach speed in cruise phase. Stealth technology and guidance system with advanced embedded software provides the missile with special features.
- Surface-launched, Block I
- Ship-launched, anti-ship variant (operational)
- Ship-launched, land-attack variant (operational)
- Land-launched, land-attack variant (operational)
- Land-launched, anti-ship variant (In induction, tested on 10 December 2010)
- Surface-launched, upgraded variants
- BrahMos Block II land-attack variant (Operational)
- BrahMos Block III land-variant (being inducted)
- Anti-aircraft carrier variant (tested in March 2012) – the missile gained the capability to attack aircraft carriers using the supersonic vertical dive variant of the missile that could travel up to 290 km.
- Air-launched, anti-ship variant (under development)
- Air-launched, land-attack variant (under development)
- Air-launched, miniaturised variant (under development)
- Submarine-launched, anti-ship variant – Tested successfully for the first time from a submerged pontoon on 20 March 2013.
- Submarine-launched, land-attack variant
The missile has flight range of up to 290km with supersonic speed all through the flight, leading to shorter flight time, consequently ensuring lower dispersion of targets, quicker engagement time and non-interception by any known weapon system in the world.
It operates on `Fire and Forget Principle`, adopting varieties of flights on its way to the target. Its destructive power is enhanced due to large kinetic energy on impact. Its cruising altitude could be up to 15km and terminal altitude is as low as 10 meters. It carries a conventional warhead weighing 200 to 300 kgs.
Compared to existing state-of-art- subsonic cruise missiles, BRAHMOS has:
– 3 times more velocity
– 2:5 to 3 times more flight range
– 3 to 4 times more seeker range
– 9 times more kinetic energy
Brahmos air-launched version is getting ready to be soon test-flown from Su-30MKI fighter of the Indian Air Force (IAF)
The development work related to the Air launch version of the missile is complete. Work has begun with Sukhoi design bureau, HAL, and the IAF for interface requirements and installation of Brahmos on Su-30MKI. Integration of the air-launched version of Brahmos is currently at an advanced stage.
Two aircraft have beed earmarked by the IAF for the initial launch trials which will commence from 2014. onwards, so that the induction can start in this year. Installations on other aircraft will depend on user requirements.
Su-30MKI has max. speed of 2 Mach with a single in-flight range of 5200km. A total of 8.000kg payloads can be carried by it in a maximum altitude of 17km.
Recently journalists had chance to visit OKB “Sukhoi” and see and look at the new training simulator designed for training pilots multipurpose fighter Su-35.
The Su-35 is a deep modernization of the Su-27 and belongs to a generation 4 ++. The aircraft is designed for air superiority, as well as to destroy air ground and surface targets.
Inside fighter Su-35 is fifth-generation technologies that provide superior fighter in its class. Distinctive differences of the Su-35 to Su-27 are new engines with increased thrust TVC, wide range of aircraft weapons, new avionics based on digital information management system and software, a new set of on-board radio-electronic equipment with a phased array radar and two-stage hydraulic drive, etc… Radar of the Su-35 can detect the type of fighter with the goal of flight efficiency dispersion in three square meters at a distance of about 400 km.
The aircraft has ultra-high maneuverability at low and near-zero rates. This capability is provided through the use of special aerodynamic design and the latest engines with thrust vector control (TVC).
OKB “Sukhoi” plans to make an training complex. It consists of an integrated simulator, procedural and educational computer class flight and engineering technical staff, who are united in a single information and methodological framework that will make all the things complex for training of pilots and engineering staff together.
The class is theoretical training with an automated control knowledge elements and are processed in a procedural simulator and then on the complex, which looks similar to origin cabin of the Su-35 fighter (closing lantern, safety harness, with a spherical dome visualization 270×110 degrees.), and it can practicing almost all kind of processes and problems.
It can be used in network so can connect up to 16 simulators and at the same time perform group training pilots. Over time, it will be possible to combine different types of exercise equipment in one information environs – training -simulator complex. In the future its planned to integrate simulators of other Russian developers.
Integrated simulator purposely is not equipped with mobility system, because the system can simulate only a small part of a large range of highly maneuverable fighter overload, and with mobility will show and display inculcate false skills.
The simulator can perform almost all the same tasks as the pilot is in the plane, including air refueling and the most important thing – testing of emergency situations. This simulator even surpasses the real plane because simulate some troubles and failures situation which are in reality very dangerous, and sometimes impossible. And this is one of the key functions of the simulator.
Workplace of the Su-35 pilot in full flight simulators is a ventilated enclosed cabin type, where there are everything necessary for comfortable combat mission.
On desk with monitors, outside the cockpit, is instructor place.
The basic controls are: Pilot control stick, engine control levers and pedals.
Information tools are collimator aviation pilot light with a control panel display, which displays flight information, two MFI-35 (multifunction display) every 15 ” control integrated system backup devices, multi-function remote display with a working field 4×5 ” helmet-mounted display system and a voice alarm system.
Multi-function board with a working field 4×5 ” is used to configure all aircraft systems, including radar sighting and navigation equipment, weapons, video recording system.
Automatic thrust control and automatic control system, allows, pilot to keep control a desired rate of movement in all maneuvers and in any conditions or fully automatically keep the aircraft on the route in accordance with the flight plan. The must-do of the pilot is reduced only to the take-off and landing tasks, as well as deciding on the use of weapons.
How we fly here?
First, the instructor make a flight scenario of the exercises with given tactical and meteorological conditions on a real map in a given area. Also, the instructor can quickly enter into a flight or cause failures and faults by monitoring the reactions of the pilot.
Workplace of the instructor is desk with multiple monitors. On the three-dimensional map shows the pivot points, the turning points of the route, and some goals. On another monitor instructor is monitoring the reaction of the pilot, authorities and management and flight parameters. On the third display is general view of the simulator, etc …
Any of the buttons, displays, conditions,…instructor have possibility to zoom in virtual on his monitor.
In fact, flight is happening by itself. The learner is in the cockpit, and the instructor at his workplace. After the training, there is debriefing.
In the photo test pilot OKB “Sukhoi” Sergey Chernyshev performs a test flight and shares his impressions with reporters.
According to Sergei, the philosophy of modern combat mission is as follows: a pilot taking off and waits until the plane automatically to reach a given point; then he decides to use of weapons in accordance with the combat mission (presses the button “defeat the enemy”), waiting until the plane comes back to the base. Thats all.
“The list of tasks to be solved and is already doing this plane is huge. It is characterized by an enormous range of altitudes and speeds, impressive range and endurance, a huge range of weapons that can be used at any time and in any weather conditions. And all these possibilities controls only one person! ”

T-10 Flanker A
Everything began at Sukhoi Bureau ending 1969. SSSR (USSR) needs some air superiority fighter to catch up USA FX program F-15 which started 1966.
Prototype of the Su-27, factory code T-10 was finished September 1971. After concept was presented, Soviet Air Force heads decided to go parallel with two designs. One by Mikoyan lighter version (now well known Mig-29 Fulcrum), and heavier by Sukhoi.
Development of the Su-27 was approved by Soviet government in 1976., so Sukhoi started to build first three T-10 prototypes (two for flight testing and one for structural testing). The first two flying prototypes of the Su-27 were fitted with AL-21FZAI engines.
Construction of the first prototype T10-1 was completed in April 1977. On 20 May 1977, the design bureau’s chief pilot V.S. Ilyushin performed the first flight. In May 1978, the testing programme was expanded to cover a second prototype, T10-2, and the year after that, in 1979, it received the prototypes T10-3 and T10-4, fitted with operational engines AL-31F. This was the first “unstable” fly-by-wire aircraft in the Soviet Union.
In the summer of 1977, after Sukhoi’s chief pilot, Hero of the Soviet Union Vladimir Sergeyevich Ilyushin, made the first flight in the T-10, and testing began. All went well, and 10 more aircraft were begun.
The second prototype T-10-2 was built in 1978, but it was destroyed on its second flight and the pilot was killed. The cause was shortcomings in the control system.
The same year Sukhoi built a third and a fourth prototype T-10-3 and T-10-4. They received new AL-31F engines, but the stability problems continued. Five new prototypes were built for expanded test flight program T-10-5, -6, -9, -10, -11. The seventh and the eight versions were kept on the drawing board waiting for possible changes. During the next four years the Su-27 underwent extensive redesign program under Mikhail Simonov’s supervision, which resulted in the T-10S, developed from the T-10-7.
The T-10S was lost in an accident on September 3, 1981. The second T-10S came from the production line with designation T-10-12 and with new airframe structure. That prototype was lost too, on December 23, 1981. The plane broke down in a high-speed test and the pilot was killed. The T-10-8 prototype was assembled in 1982 to be used in strength tests. Thus the total number of aircraft in the test program rose to 14.
The T-10S prototype evolved into the production version Su-27P during the year 1985, when it was introduced to service. Sukhoi manufactured about 200 such planes for the Air Defense Force.
The radar is coherent RLPK27pulse-doppler radar, which is able to track 10 targets and engage 2 targets simultaneously. Geophysica NPO optical-electronic system supplements the radar. The system’s laser rangefinder has 8 km range and the IR finder’s detection range extends to as far as 50 km, depending on the IR contrast. The electro-optical system can be connected to the pilot’s helmet sight.
As compared to the MiG-29, the benefits of the Su-27 in terms of operation range and useful load were evident. Thus the FrontalAviation soon directed its interest to the new aircraft and had ordered about 150 examples by the beginning of the 1990s.
