Rumpler C VIII

  Although included in the C type category, the Rumpler C VIII had been developed with the intention of providing a good operational trainer for aircrews nearing the completion of their training. Previously, little equipment had been available other than the low-powered B type two-seaters and obsolete C types. The C VIII was provided to give training with emphasis on the observer's curriculum - including gunnery, observation, radio and photography - on an aircraft approaching more nearly operational standards, yet with ability to be operated economically, largely due to the installation of a 180 h.p. Argus engine.
  Undoubtedly the spotlight fell upon the Jagdstaffeln, but it was the two-seater Fl. Abt. that did the donkey work in the German Air Force. With the approach of the final year of the war and the planned ultimate offensive on the Western Front for March 1918, it was hoped by the improvement and intensification of training of two-seater crews to achieve superior results, especially with more adequate protection from the Jastas and Schlachtsta formations. To facilitate this higher standard of training, the Rumpler C VIII came into use towards the end of 1917 with the F.E.A. (Flieger Ersatz Abteilungeri) "Flying Training Units".
  The C VIII underwent its official Type Test at Johannisthal in November 1917, and some examples were also sold to the Dutch Government for use with their flying services.
  In construction, the C VIII continued the style of its predecessors. Fuselage longerons were of ash forward, spliced into spruce in the rear half; spacers were of steel tube forward and spruce aft. The fore part of the fuselage was ply covered, except for the rounded nose panel of metal and the metal panels fairing the cylinder block; these now being much squarer than formerly. The rear part of the fuselage was fabric covered. Tail surfaces were all interchangeable with those of the C IV and C VII, with steel-tube framing and unbalanced control surfaces. The tailplane was of reversed camber section.
  The wing surfaces reverted to the C I type in general shape, with both wings having angularly raked tips and being of parallel chord. The lower wing had long shallow cut-outs at the root to improve downward vision from the rear cockpit, while the upper wing had a narrow, rounded, centre-section cut-out. Conventional twin hollow box-spar construction was followed, with fretted ply ribs capped with softwood and false ribs spaced between the main ribs. Ailerons were unbalanced and of steel-tube framing. The upper wings were supported on a typical Rumpler trestle-type centre-section cabane, to which was also fixed the semicircular radiator. Both wings were swept at an angle of some 2 1/2°.
  A streamlined steel-tube undercarriage chassis was fitted, and the wheels were sprung with spiral-steel springs. An orthodox steel-shod, ash tailskid was hinged to and internally sprung within the rear bay of the fuselage.
