Among the many Soviet ANT-25 aircraft (RD) - one of the most famous. His story began 7 December 1931 city, when at the suggestion of KE. Voroshilov was decided to build a special aircraft to record flight at a distance. Aircraft Design for bruising world distance record was entrusted OKB TsAGI. Conceptual design of the RD was prepared by AN. Tupolev summer 1931 g. Responsible for the development and construction of the aircraft was appointed designer PO. Dry.

Conceived and built as a taxiway was single-engine all-metal cantilever nizkoplan with a very high aspect ratio wing. The ratio of its span to chord exceeded 13! Before RD machines with narrow and long consoles did not exist. Built by repeated purges wing was easy and strong enough, to house the fuel, which weighed quantity 52% from takeoff. Wing skin is corrugated for stiffness. Aircraft design was completed in early 1932 g.
The first flight of ANT-25 (RD) done 22 June 1933 city, I drove the car test pilot MM. thunders. By plane scripting engine M-34 power 750 hp, forced later to 874 HP. However, flight data did not meet the designers, fuel supply only enough 48 flight hours - equivalent to the entire range of 7200 km, but it was not enough. Even before the first flight in August 1932 g. the construction of an understudy RD engine M-34P power 800 HP. The first flight of the aircraft understudy performed 10 September 1933 g. (pilot MM. thunders). Flight data has increased significantly, expected range was already 10800 km, but this was not enough. "Culprit" was corrugated paneling, possess considerable resistance. It was decided obtyanut wing on top of the canvas. The entire plane lacquered, a leading edge and a screw polished, We did elongated Fairings. Outbound Flight began 30 June 1934 g. The crew of pilots MM. Gromova, AM. Owl and navigator I.T. Spirin set the record flight range of the USSR.
IPG-25 (RD) flown 4465 km of 27 no 21 min. A month later, the same pilots improved record: for 39 no 1 min was passed 6559 km. In September, Flying over the triangle Moscow - Ryazan - Kharkiv, M crew. M. Gromov for 75ch 2min covered a distance 12 411 km, far exceeding the world record of French pilots Bossutro and Rossi. 20 July 1936 g. Another outstanding flight from Moscow was committed - the Far East with a crew of VP. Chkalov, G. F. Baydukova and AV. Belyakova. The flight was successful, the plane landed on the island Udd. ANT-25 had been in the air 56 no 20 min flying 9374 km.
The crew asked the government to allow a flight on the route Moscow - North Pole - America. After hearing the report of pilots, the government gave "good". 18 June 1937 g. at 4 no 5 min Shchelkovo airfield was taken launch this unprecedented flight. 20 June 19 no 30 Moscow time ANT-25 landed at the airport at Barack Vancouver (USA). for 63 no 16 min was passed at a distance 11 430 km. After just three weeks, the crew MM. Gromova, AB. Yumashev and SA. Danilina made another flight to America via the North Pole. The pilots set a new world distance record. The plane was in the air 62 no 17 min, breaking away 11500 km. These historic flights demonstrated to the world not only the courage and skill of our pilots, but also a high level of domestic aircraft.
