Junkers Ju 287: Report February 1945: Roll- und Schiebemessungen am Modell Ju 287

This publication is a reprint of a secret report from the German Research Institute for Aviation (DVL) at Berlin-Adlershof from February 1945 to the Reichsluftfahrtministerium (RLM). The report examines the spinning behavior of a 1:11 scale model of the Junkers Ju 287 with forward swept wings in the institute's wind-tunnel. The stall behavior was also examined with the flow directly from the front and at small sideward angles. As an advantage of the forward-swept wings, the ailerons kept their effectiveness even at high angles of attack when the aircraft starts to stall. The model with a span of 1754 mm had no empennage. It carried one engine at each fuselage side and a twin nacelle under each wing. But some measurements were carried out without engines for comparison. This unique piece of aviation history comes with 52 pages, diagrams, drawings, and wind-tunnel photographs from the model examined at the DVL.
