Albatros Dr II
Built in 1918, the Dr II consisted mainly of D X components with a triplane set of wings. These were of parallel chord, heavily staggered and braced with very wide I struts reminiscent of the Sopwith triplane. Ailerons were fitted to all wingtips. Frontal-type radiators were mounted in the centre-section between the upper and centre wings, and undoubtedly caused considerable drag. Engine, 195 h.p. Benz lVb vee-eight. Span, 10.0 m.
