Bluemarkers Bluemarkers shows Canards(above)Angle of attack
The Su-30MK's aerodynamic configuration is an unstable-in-longitude triplane**. To increase lifting effectiveness and enhance maneuverability of the aircraft, canards*** are installed. They are deflected automatically to ensure controlled flight at high angles-of-attack. However, canards are installed only in some Su-30 variants like the Su-30MKI.
[**In aviation, relaxed stability refers to the tendency of an aircraft to change its attitude and angle of bank on its own accord. An aircraft with relaxed stability will oscillate in simple harmonic motion around a particular attitude at an increasing amplitude.The latest generation of fighter aircraft often employ design elements which reduce stability to increase maneuverability]
[*** Canard:an airframe configuration of fixed-wing aircraft in which the tailplane is ahead of the main lifting surfaces, rather than behind them as in conventional aircraft, or when there is an additional small set of wings in front of the main lifting surface]
Avionics
Radar: Either a N001VE or Phazotron N010 Zhuk-27 or an N011M BARS pulse Doppler passive electronically scanned array radar. Capable of detecting and tracking up to 15 air targets, while concurrently attacking 4 of them. The N011M BARS radar (featuring a 20-m (65.6 ft) resolution) ensures detection of large sea-surface targets at a distance of up to 400 km (248.5 mi), and small-size ones at a distance of up to 120 km (74.5 mi).
Other avionics include an integrated optronic sighting-and-navigation system with a laser gyro navigation system; helmet-mounted displays, a head-up-display, multi-function color LCDs with image mixing ability; and a GPS system (GLONASS/NAVSTAR compatible).
IR and laser sighting pods to detect and engage small-size ground targets are available for installation. The aircraft is provided with an ECCM facility intended to subvert hostile electronic and electro-optical countermeasures.The countermeasures system includes a pilot illumination radar warning receiver, chaff and infrared decoy dispensers, and an active multi-mode jammer located in the wingtip pods.
The aircraft features autopilot ability at all flight stages including low-altitude flight in terrain-following mode, and individual and group combat employment against air and ground/sea-surface targets. Automatic control system interconnected with the navigation system ensures route flight, target approach, recovery to airfield and landing approach in automatic mode.
Pugachev's Cobra and other combat maneuvers
The integrated aerodynamic configuration, combined with the thrust vectoring control ability, results in unprecedented maneuverability and unique takeoff and landing characteristics. Equipped with a digital fly-by-wire system, the Su-30MK is able to perform several unique maneuvers. They include the well-known Pugachev's Cobra and the Bell. While performing a somersault maneuver, the aircraft makes 360-degree turn in the pitch plane without any loss of altitude. In the Controlled Flat Spin maneuver, the aircraft performs several full turns in the horizontal plane, with zero forward speed, virtually on the spot.
[The Pugachev Cobra is a fighter aircraft manoeuvre. The manoeuvre allows for very quick turns which can make an attack fail or put the pilot in a position to execute an attack. Pugachev Cobra is known to be one of the most aesthetic, dramatic, demanding and beautiful manoeuvres performed at air shows worldwide. The manoeuvre is so named after the Sukhoi OKB (design bureau) test pilot Viktor Pugachev, who first performed the maneuver.]
