The Grigorovich MUR-1, (MUR - Morskoi Uchebnyi Rhône - seaplane trainer Rhône), was a trainer flying boat built in the Soviet Union in the mid-1920s.

Development

The MUR-1 was developed by the Grigorovich Design Bureau in response to a Red Air Force requirement for a flying boat suited to training naval pilots. The MUR-1 differed from the Grigorovich M-5 in that it used a more powerful engine, single bay wings with thicker section, and stronger tail structure. Speed was increased, but other characteristics suffered. Increased weight of the tail structure necessitated carrying Шаблон:Cvt of ballast in the nose. Test flights of the MUR-1 showed no discernable improvement over the M-5.[1]

To remedy aerodynamics deficiencies during its initial flight trials, the MUR-1 was modified with pressure sensors and a new hull, and redesignated MUR-2, with input from TsAGI engineer N.N.Podsevalov. Test flights were conducted 1929-1931 with the intent to test load condition during taxi, takeoff and landing.[2]
