Junkers T 29 29 pioneered the patented Junkers "Doppelflügel" "double wing" control system - whose concept was used through to the Third Reich's Junkers Ju 87 "Stuka" dive bomber - using full span ailerons, later used for both ailerons and flaps, hinged just below the wing trailing edge and fully exposing the entire control surface cross-section to the slipstream, forming a slot between the two surfaces. In normal flight these were used as standard ailerons, but they could be lowered like flaps for landing whilst retaining the differential movement needed for lateral control. The fuselage was flat sided with rounded decking, the Junkers
Junkers Ju 352 Junkers Ju 352 The Junkers Ju 352 "Herkules" ("Hercules" in German) was a German World War II transport aircraft that was developed from the Junkers Ju 252. During the late spring of 1942, the Junkers-Dessau project office was instructed by the Reich Air Ministry (RLM) to investigate the possibility of redesigning the structure of the Junkers Ju 252 transport to make maximum use of non-strategic materials, replacing the Junkers Jumo 211F engines of the Ju 252 with Bramo 323R radial engines. The result followed closely the aerodynamic design of the Ju 252 but was an entirely new aircraft. The wing
