The MDR-3 (a.k.a.11) was a long-range flying boat designed and built in the USSR from Template:Avyear.
Development
In 1931, Chyetverikov was commissioned to design a new long-range flying boat for MA (Morskaya Aviatsiya – naval aviation), for which Chyetverikov used few new parts, borrowing wings, tailplane and engine nacelles (mounted above the wing) from the Grigorovich TB-5 and a scaled-up Grigorovich ROM-2 fuselage. The use of ready designed or built components led to quick construction of the prototype which was ready for flight tests in Dec 1931, which commenced in January Template:Avyear after the aircraft was transported to Sevastapol in the Crimea. Despite fast construction and excellent structural qualities, results of the flight tests were disappointing, with a takeoff time of 36 seconds, a climb rate of less than a metre per second and a ceiling of only 2,200m, resulting in the whole project being transferred to KOSOS (Konstrooktorskiy Otdel Sektora Opytnovo Stroitel'stva – section of experimental aeroplane construction), due to lack of faith in Chyetverikov's abilities to rectify the poor performance. The MDR-3 became the basis of the ANT-27, MDR-4 and MTB-1.
