The Su-27M. Photo. Story. Characteristics.


In 80-ies the idea to create a modified Model on the basis of the Su-27. Su-27 Initially conceived as a long-range interceptor for the Air Defense Forces and the Air Force, but later decided that the fighter is capable of more. Confirmation of the results of the tests began. They Su-27 far demonstrated the ability of the flight and the effective implementation of combat tasks.

Sioux 27M on the cipher of the plant listed as T-10M fighter designed for air superiority over the American counterparts and F F-15-16. The initial version of the modification number of radar system RCS-27, medium-range missiles of class "air-to-air" ARS and special weapons to destroy ground targets. Also, the equipment had to go upgraded navigation system and the onboard electronic systems of defense. Information about the purpose, location, distance, completing with, and brings to the wide multi screen with a simplified console. Additional information thanks kolimatornomu indicator moves to the background of the windshield.

Engineers behalf of the Ministry of Health PO Sukhoi started work immediately after the decision by the Commission of the Council of Ministers in December 83-year. Robot Designer headed MN Simonov. The first designs focused application of additional front horizontal tail type, which until then were tested for T-1024. In addition, the first phase of improvements included modification of the remote control system and uluchsheniedozapravochnoy system during the flight that were tested on the T-10U-2. To increase the range of flight planned to install engines AL-31F and using external fuel tanks (under the wings) with capacity up to 2000 liters.

In 1985 prepared a preliminary draft of the future Su-27M. The main changes concerned the avionics. The composition of the main components included RCS-27, opto-electronic sighting complex navigation, radar opposing system, means of communication. The additional components included remote control system, instrument pointing device, control system, the defendant gosopoznovaniya and indication and registration. Almost all the complexes were calculated on the digital calculation.

The radar system included a small radar N012 rearview and medium NSSI forward-looking radar to the presence of slot antenna (developed in NIIP "Dawn"). N011 had increased range target detection and a field of view of the space in the air. Also it helps build a large number of possible opponents and simultaneous attacks, inherent mapping. The new technical solutions adopted in the development of radar are: - the use of broadband multi-mode transmitter with high efficiency, - installation of a low noise amplifier input RF power, - digital processing of the radar signal - the use of a digital high-performance computing systems. Rear of visibility due to circular view of the entire space. Rear surveillance radars deployed in the center of the tail boom of the fuselage.

RCS-27 provides:

  1. The application of pre-emptive strike against the enemy.

  2. Attack ground and sea targets outside the scope of air defense zone.

  3. The use of weapons on the target mode radar information.

  4. Making flying at low altitudes.

  5. Participation in gruppovoyoperatsii.

  6. Automation of all stages of flight combat use.

  7. Troubleshooting and automatic monitoring of all systems.

  8. Detection of typical air and ground targets with a range 200km.

  9. Simultaneous tracking of air targets in the rear hemisphere machine.

  10. The work in noisy environments.

The structure of the optical-navigation equipment includes PNA 10M, optical-location station OLS-27K, helmet-mounted target designation system "gap-ZOOM", angular velocity meter type and JMA IUSLU. Flight navigation system presented a digital calculator, SHS 2TS-y, altimeter RV-21, the system SPKR, the technical mechanism for short- and long-range navigation A-312 and A-723, equipment HVAC aircraft of A-315, speed Doppler, automatic radio complex CANCER-22, information complex vertical IR VC-80 and ACS-10M.

By airborne defense added a new electronic intelligence station, staging APT-50, teplopelengator missiles onboard computer control device, and jammer "Sorbatsiya."

Absolutely completely updated information and control field in the cockpit. It was set three multi-functional high-contrast monochrome Thermal imaging indicators such as a touch-tone frame and the indicator on the glass background. Electromechanical devices are responsible for duplicating functions, and their number has significantly decreased. Ejection seat found an increased inclination of the back, which helps alleviate the congestion tolerated during maneuvering.

The number of portable missiles "air-to-air." Sioux 27M 12 able to carry units. In the overall composition of the aircraft weaponry also includes the RVV-AE, 8-27 of R and R-27E the presence of ARS, short-range missiles R-73, used in passing maneuver battle, cannon GSH-301. To carry out combat operations related to the objectives of the land or sea plane can be equipped with missiles "air-surface", namely X-29T - homing missiles with television GOS X 31P - protivolokatsionnye missiles with passive GSP. In sea combat fighter arm antiship missiles Kh-31L and bombs KAB-500Kr corrected type of unguided weapons - bombs, NAR and the like. The device is able to move 16 bombs FAB-500M54, 36 bombs FLB-250M54, 12 bombs FAB-500M62, 48 bombs OFAB-100-120 and many others.

All the new equipment has increased the overall weight of the aircraft at 1500kg. Maximum weight of the aircraft during the flight with a full ammunition and tanks tucked reaches 34000kg. Because of this, it was necessary to strengthen the chassis and in general the entire structure.

The first copy of the aircraft began to gather in 1987 year. And in June, 88-year was made a test pilot OKB OG Tsoi first flight of the T-10M-1. Six months later, a second car experienced gathered in Komsomolsk-on-Amur.
