Design
The multirole Be-200 can be configured as an amphibious water drop fire-fighting aircraft, a freighter, or as a passenger aircraft — the pressurised and air conditioned cabin allowing transportation of up to 72 passengers. The Be-200 can also be equipped for special missions. When configured as an air ambulance, the aircraft can carry up to 30 stretcher patients and seven seated patients or medical crew. In the search and rescue role, the aircraft can be equipped with searchlights and sensors, an inflatable boat, thermal and optical surveillance systems, and medical equipment. The search and rescue variant can accommodate up to 45 persons. The aircraft is also capable of being configured for anti-submarine warfare duties.
The Be-200 fire-fighter suppresses fires by dropping water and/or chemical retardants. Eight ferric aluminium alloy water tanks are located under the cabin floor in the centre fuselage section. Four retractable water scoops, two forward and two aft of the fuselage step can be used to scoop a total of 12 tonnes of water in 14 seconds. Alternatively, the tanks can be filled from a hydrant or a water cistern on the ground. The water tanks can be removed quickly for carrying cargo. Water can be dropped in a single salvo, or in up to eight consecutive drops. The aircraft also carries six auxiliary tanks for fire-retarding chemical agents, with a total capacity of 1.2 m³. The aircraft can empty its water tanks over the site of a fire in 0.8 to 1.0 seconds when flying above the minimum drop speed of 220 km/h (135 mph, 120 kn)
The aircraft is powered by two pylon-mounted D-436TP engines. The D-436TP is a specific "maritime" corrosion-resistant version of the D-436 three shaft turbofan engine, designed especially for the Be-200 amphibian, by Ivchenko Progress ZMKB and manufactured by "Motor Sich" in Ukraine. These are mounted above the wingroot pods on the landing gear fairings to prevent water spraying into the engines during take-off and landing.
The Digital Flight Control (Fly-by-wire) cockpit is fitted with modern navigation systems such as satellite navigation (GPS), FMS, autopilot and weather radar. The ARIA 200-M all-weather integrated avionics system developed by Honeywell with the Moscow Research Institute of Aircraft Equipment, uses six 152 x 203 mm (6 x 8 in) LCDs to display information to the two-man crew.
The Be-200 is a high-wing T-tail monoplane. the hull is of single step design with a high length-to-beam ratio, which contributes to stability and controllability in water. The Be-200 airframe is constructed of aluminium alloys with corrosion-protection treatments. Selective use is made of titanium, composites and other corrosion-free materials. The wings are fitted with underwing stabiliser floats. The hydraulically operated retractable landing gear units all retract rearward, and each unit is twin-wheeled. A water rudder provides steering in the water.
The Be-200 can operate from either a 1,800 m long runway or an area of open water not less than 2,300 m long and 2.5 m deep, with waves of up to 1.3 m high.

Famous quotes containing the word design:
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (1613–1680)
“What but design of darkness to appall?—
If design govern in a thing so small.”
—Robert Frost (1874–1963)
“If I knew for a certainty that a man was coming to my house with the conscious design of doing me good, I should run for my life ... for fear that I should get some of his good done to me,—some of its virus mingled with my blood.”
—Henry David Thoreau (1817–1862)
