ANT-20 different from ANT-16 (TB-4) only in size and carrying capacity. He had to bear the 1,5 tons more load and use a small airfields. With his takeoff length of the runway should be 300-400 m. The result was a new wing, which had an elongation and an area different from the wing TB-4. Almost the entire surface was corrugated. As for the power plant, it consisted of 8 engines M-34FRN (each 900 hp). Wood screws with a diameter of 4 m. Initially, it was planned to establish 6 engines, but their power is not enough. Navigation equipment provides operation at any time, including allowing carry landing on unprepared terrain.
