SU-27M Best Aircraft Fighter Generation
Development of the SU-27M single-seat multirole high-manoeuvrability fighter, which export variant was dubbed Su-35 in 1992, kicked off for the Soviet Air Force and Air Defence Force in the mid-1980s as a comprehensive upgrade of the production Su-27. The upgrade comprised fitting the aircraft with a new avionics suite, introducing advanced medium-range air-to-air active radar homing missiles and guided air-to-ground weapons, modifying the aerodynamic configuration through introducing the canards and 3D fly by-wire control system, extending the flight range by beefing up the internal fuel capacity and introducing the in-flight refuelling system, etc.
The first Su-27M prototype the T10M-1 (No 701) – was derived from a production Su-27 and flown for the first time by the Sukhoi design bureau’s test pilot Oleg Tsoy on 28 June 1988. The second prototype joined the tests in January 1989, and the late ‘80s saw the KnAAPO plant start preparations for launching the preproduction batch of the SU-27M. The fly-out of the lead Su-27M made by KnAAPO – the T10M-3 (side number 703) – took place on 1 April 1992. In September of the same year, the aircraft was unveiled at the air show in Farnborough, the UK, under a new designation of Su-35 assigned to the export version of the Su-27M.
To test the new avionics, three more SU-27M prototypes (numbers 705 through 707) were derived from production Su-27s, and KnAAPO in 1993–95 built five more preproduction Su-27Ms (numbers 708 through 712) for the official trials and three early production aircraft for the Air Force. The latter were handed over to the Defence Ministry’s State Flight Test Centre (GLITs) in Akhtubinsk in 1996 for Air Force crews to learn to fly them.
Two last preproduction Su-27Ms (No 711 and 712) were used in the mid-‘90s to test an advanced phased array radar, the N011M, that later served the base for the Bars radar now mounted on resolution. They are designed to receive, process and display in numerous windows graphic, numerical/letter and symbolic information, television imagery fed by onboard TV sensors and overlayed with numerical/letter and symbolic synthesised data as well as generate and feed digital video signals to the video recorder system.
The multifunction display with the integral display processor is intended to show relevant information and issue commands by pushing buttons around it throughout the flight. The IKSh-1M collimator HUD with the integral processor is designed for the crew to watch the collimated display of sighting data in the form of marks, digits and other symbols. The HUD’s field of vision is 20°x30°.
