Grigorovich MR-2
The Grigorovich MR-2 was a long-range reconnaissance flying boat designed by the Grigorovich Design Bureau for the Soviet Navy The Soviet Navy was the naval warfare Military, uniform service branch of the Soviet Armed Forces. Often referred to as the Red Fleet, the Soviet Navy made up a large part of the Soviet Union's strategic planning in the event of a conflict with t ... in the late 1920s. Design The MR-2 was similar to the MRL-1 but had a more powerful engine and larger upper wing, while the hull design was improved and less expensive materials used in its construction. Flights beginning in September 1926 impressed the MR-2's designers, and state acceptance trials were carried out by VVS pilot F.S.Rastegaev. One flight on October 19, however, ended in disaster when the MR-2 lost stability, and longitudinal oscillations with increasing amplitude resulted in steep dive, causing the aircraft to crash into the water up-side-down.

Soviet Navy
The Soviet Navy was the naval warfare Military, uniform service branch of the Soviet Armed Forces. Often referred to as the Red Fleet, the Soviet Navy made up a large part of the Soviet Union's strategic planning in the event of a conflict with the opposing superpower, the United States, during the Cold War (1945–1991). The Soviet Navy played a large role during the Cold War, either confronting the North Atlantic Treaty Organization in western Europe or power projection to maintain its Warsaw Pact, sphere of influence in eastern Europe. The Soviet Navy was divided into four major fleets: the Soviet Northern Fleet, Northern, Pacific Fleet (Russia), Pacific, Black Sea Fleet, Black Sea, and Baltic Fleet, Baltic Fleets, in addition to the Leningrad Naval Base, which was commanded separately. It also had a smaller force, the Caspian Flotilla, which operated in the Caspian Sea and was followed by a larger fleet, the 5th Operational Squadron, 5th Squadron, in the Mediterranean Sea. The ...

Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag (aerodynamics), drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. ...

Flying Boats
A flying boat is a type of seaplane with a hull (watercraft), hull, allowing it to land on water. It differs from a floatplane in having a fuselage that is purpose-designed for flotation, while floatplanes rely on fuselage-mounted floats for buoyancy. Though a flying boat’s fuselage provides buoyancy, it may also utilize under-wing Float (nautical), floats or wing-like hull projections (called sponsons) for additional stability. Ascending into common use during the First World War, flying boats rapidly grew in both scale and capability during the interwar period, during which time numerous operators found commercial success with the type. Flying boats were some of the largest aircraft of the first half of the 20th century, exceeded in size only by bombers developed during the Second World War. Their advantage lay in using water instead of expensive land-based runways, making them the basis for international airlines in the interwar period. They were also commonly used as mar ...
