Kondor D 7
  Appearing late in 1917, the single-seat lighter D 7 bore unmistakable signs of Albatros influence, although design of the machine is credited to Westphal. Bracing of the wing cellule was novel, as was also the slinging of the ply-skinned fuselage between the wings. The extremely robust undercarriage chassis was attached to the main longerons, which were in the vertical and horizontal centre-line planes. The fuselage, with underslung lower wing, evolved from an earlier triplane design which was a failure. The D 7 also failed to come up to expectation. Engine, 160 h.p. Mercedes D III. Span, 8.5 m. (27 ft. 10 3/4 in.). Length. 6.2 m. (20 ft. 4 1/8 in.). Height, 2.3 m. (7 ft. 6 1/2 in.). Area, 15.7 sq.m. (169.5 sq.ft.). Weights: Empty, 590 kg. (1,298 lb.). Loaded, 785 kg. (1,727 lb.).

KONDOR D 7 Germany

  The D 7 single-seat fighter was essentially a re-work of the original Kondor triplane fighter as a biplane, retaining the plywood-covered steel tube fuselage, tail and lower wing. The bracing of the wing cellule was novel, the interplane struts taking the form of inverted tripods, and the fuselage was mounted between the wings, the lower wing being braced to the robust undercarriage rather than directly to the fuselage. The initial flight tests of the D 7 are unrecorded, but an Idflieg report stated that the D 7 had now been fitted with a standard 160 hp Mercedes D III engine with which it was expected to resume flight testing in early May 1918. The D 7 did not make an appearance at the second D-type contest in June 1918, development having apparently been discontinued meanwhile.

The D 7 was a biplane rework of the earlier Kondor fighting triplane flown in October 1917.
