The Focke-Wulf S 39 is a German training and reconnaissance aircraft developed in the early 1930s by the former Focke-Wulf AG based in Bremen .

development

The S 39 was the first aircraft type that was designed by Focke-Wulf under the direction of Kurt Tank . The construction of a training and reconnaissance aircraft was carried out in 1931 by Wilhelm Bansemir. The only copy with the serial number 98 completed its maiden flight in the same year and was registered in April 1932 as Fw 39 with the registration D-1708 for Focke-Wulf AG. The S 39 was designed as a military aircraft, so the rear cover could be removed in the rear part of the crew cabin and a defense post installed. As in Germany but the construction and testing of such types were not allowed, the S was 39 in 1932 that still Soviet Union transferred and the in Lipetsk contained secret aviation school of the army tested. What happened to the plane in the subsequent period is not exactly understandable. After the test site was closed in 1933, it is said to have been brought back to Germany and from 1937 flown as Fw 39 B with the registration D-IQIM first at the Rechlin test center and then at the German Aviation School in Berlin-Staaken and later handed over to the Soviet Union . But it is also possible that this happened when the base was abandoned, because the types that were located there at the time were largely taken over by the Soviet side. In addition, the aforementioned mark appears to have been assigned to an Ar 66 .

construction

The S 39 was a high-decker in mixed construction . The continuous wing had a slight sweep and was connected to the fuselage by struts or supported on the rigid main landing gear by V-legs running from its center. The tailplane's horizontal stabilizer was also braced.
