Editing DFS 346 (section)

===Post-War===
On 22 October 1946, the Soviet [[OKB-2]] (Design Bureau 2), under the direction of Hans Rössing and Alexandr Bereznyak, was tasked with continuing its development.
The captured DFS 346, now simply called '''"Samolyot 346"''' (''samolyot'' means "airplane") to distance it from its German origins, was completed and tested in TsAGI [[wind tunnel]] T-101. Tests revealed some aerodynamic deficiencies which would result in unrecoverable [[Stall (flight)|stall]]s at certain [[Angle of attack|angles of attack]]. This phenomenon involved a loss of longitudinal stability of the airframe. After the wind tunnel tests, two [[wing fence]]s were installed on a more advanced, longer version of the DFS-346, the purpose of fences was to interrupt the spanwise movement of airflow that would otherwise bring the boundary-layer breakdown and transition from attached to stalled airflow with loss of lift and increase of drag.

This solution was used on the majority of Soviet planes with swept wings of the 1950s and 1960s. In the meantime, the escape capsule system was tested from a [[B-25 Mitchell|B-25J]] and proved promising. Despite results from studies showing that the plane would not have been able to pass even Mach 1, orders were given to proceed with construction and further testing.
