DESIGN
Airframe
The Su-30MKI is a highly integrated twin-finned aircraft. The airframe is constructed of titanium and high-strength aluminium alloys. The engine nacelles are fitted with trouser fairings to provide a continuous streamlined profile between the nacelles and the tail beams. The fins and horizontal tail consoles are attached to tail beams. The central beam section between the engine nacelles consists of the equipment compartment, fuel tank and the brake parachute container. The fuselage head is of semi-monocoque construction and includes the cockpit, radar compartments and the avionics bay.
Cockpit and ergonomics
Cockpit instrumentation The displays include a highly customized version of the Elbit Su 967 head-up display consisting of bicubic phase conjugated holographic displays and seven liquid crystal multifunction displays, six 127 mm x 127 mm and one 152 mm x 152 mm. The HUD was widely misreported to be the VEH 3000 from Thales. Variants of the same HUD have also been chosen for the IAF's MiG-27 and sepecat-jaguar-shamsher upgrades, on grounds of standardization.
Flight control
The aircraft has a fly by wire (FBW) with quadruple redundancy. Depending on the flight conditions, signals from the control stick position transmitter or the FCS will be coupled to the remote control amplifiers. These signals are combined with feedback signals fed by acceleration sensors and rate gyros. The resultant control signals are coupled to the high-speed electro-hydraulic actuators of the elevators, rudders and the canard. The output signals are compared and, if the difference is significant, the faulty channel is disconnected.
General features
The Su-30MKI on-board health and usage monitoring system (HUMS) monitors almost every aircraft system and sub-system including the avionics sub-systems. It can also act as an engineering data recorder
NAVIGATION
The aircraft is fitted with a satellite navigation system (A-737 GPS compatible), which permits it to make flights in all weather, day and night. The navigation complex comprises high accuracy SAGEM integrated global positioning system and ring laser gyroscope inertial navigation system.
PILOT EJECTION
The crews are provided with zero-zero KD-36DM ejection seats. The rear seat is raised for better visibility. The cockpit is provided with containers to store food and water reserves, a waste disposal system and extra oxygen bottles. The KD-36DM ejection seat is inclined at 30º, to help the pilot resist aircraft accelerations in air combat.
