Kondor D I
  Designed by Rethel and Ehrhardt the Kondor D I appeared in the spring of 1918. The wing arrangement followed that of the Albatros, with single-spar lower wing and vee interplane struts. Engine, 110 h.p. Oberursel U II rotary. The D I participated in the second D types Competition in June 1918 at a loaded weight of 568 kg. (1,250 lb.); it climbed to 5,000 m. (16,400 ft.) in 30.6 min.


Kondor D II
  A contemporary development of the D I, the D II differed principally in having a more conventional wing structure, and was fitted with ailerons at all four tips, those on the upper wing being balanced. Also competing in the second D types Competition, the D II climbed to 5,000 m. (16,400 ft.) in 33.1 min. at a loaded weight of 554 kg. (1,218 lb.). Engine, 110 h.p. Oberursel U II. Span, 7.59 m. (24 ft. 10 7/8 in.). Length, 4.86 m. (15 ft. 11 1/2 in.). Height, 2.41 m. (7 ft. 10 7/8 in.). Area, 13.3 sq.m. (144 sq.ft.). Weights: Empty, 370 kg. (814 lb.). Loaded, 550 kg. (1,210 lb.). Speed, 170 km.hr. (106.25 m.p.h.). Note unusual painting of cross on fin instead of on the rudder.

KONDOR D 1 Germany

  Designed by Rethel and Ehrhardt in parallel with the triplane,the D 1 single-seat fighter was an unequal-span single-bay staggered biplane powered by a 100 hp Gnome-Monosoupape rotary engine. Following Albatros practice in having a single-spar lower wing with V-type interplane strutting, the D 1 was dubbed unofficially and somewhat scathingly as the Kondorlaus and was extensively test flown by Ehrhardt. Intended armament comprised two synchronised LMG 08/15 machine guns with 500 rounds. Flight testing was initiated in the late autumn of 1917, but performance proved disappointing, this possibly being the cause of the prototype's unofficial appellation. In the spring of 1918, when Ehrhardt left the Kondor Flugzeugwerke for health reasons, redesign of the aircraft was undertaken by Walter Rethel as the D 2.

Empty weight, 855 lb (388 kg).
Loaded weight, 1,252 lb (568 kg).
Span, 24 ft 11 1/4 in (7,60 m).
Length, 15 ft 10 7/8 in (4,85 m).
Height, 7 ft 10 1/2 in (2,40 m).
Wing area, 143.7 sq ft (13,35 m2).


KONDOR D 2 Germany

  The D 2 single-seat fighter was essentially similar to the D 1, but changes included a two-spar lower wing with parallel interplane bracing struts. Power was provided by a 110 hp Oberursel Ur II rotary engine and armament comprised two synchronised LMG 08/15 machine guns. The D 2 was first flown in May 1918, and two examples participated in the second D-type contest held at Adlershof in June 1918. These were temporarily referred to for convenience as the D I (w/n 200) and D II (w/n 201), one having ailerons on all four wings and one apparently having ailerons on the upper wings only. Oblt Herman Goring, in his report on the potential of these Kondor fighters, gave his opinion that they were "very fine in regard to flight characteristics, but not worthy of further consideration owing to their poor performance". No further development of the D 2 was undertaken.

Max speed, 109 mph (175 km/h).
Time to 9,840 ft (3 000 m), 10.4 min.
Endurance, 1.5 hrs.
Empty weight, 838 lb (380 kg).

Span, 24 ft 10 4/5 in (7,59 m).
Length, 15 ft 11 3/4 in (4,87 m).
Height, 7 ft 10 9/10 in (2,41m).

Kondor D.I

  At the First Fighter Competition Kondor made an entry despite not have designed a fighter before. The Kondor D.I was a neat little fighter with single-spar lower wing and was powered by the 110 hp Oberursel Ur.II.
  Comparable in technology with the Nieuport 17 of late 1916 with its single-spar lower wing and modestly powered rotary engine, the Kondor D.I was clearly not competitive and did not compete in the competition. Unfortunately, no performance data are available. The D.I designation was a factory, not a military, designation.


Kondor D.II & D.VI

  Despite making no impression at the First Fighter Competition with its D.I, which was present but did not compete, Kondor became more active in designing fighters and fielded two D.II prototypes, Work Number 200 and Work Number 201, for the Second Fighter Competition. Again, the designations were for factory convenience and not official Idflieg designations. The D.III-D.V were not built.
  The Kondor D.II was derived from the earlier D.I by replacing the single-spar lower wing with a new, stronger two-spar wing fitted with ailerons. The revised wing cellule was stronger, gave better performance, and better roll rate for excellent maneuverability. Both Kondor D.II prototypes were powered by the 110 hp Oberursel Ur.II rotary. They were the smallest fighters at the Second Fighter Competition.
  At the competition the Kondor D.II was assessed as having very fine flight characteristics but poor performance, especially the mediocre climb, and there was no chance of a production order.

The Kondor D 1, which, flown late autumn 1917, was unofficially known as the Kondorlaus.
The only known photo of the Kondor D.I shows its V-struts with single-spar lower wing. It was powered by the 110 hp Oberursel Ur.II. By this time 110 hp was generally not enough power to be competitive with the 200 hp SE5a and the 200-220 hp Spad 13. More powerful rotary engines were in development but none were truly ready for production. The printed camouflage fabric on the flying surfaces shows its distinct pattern. The national insignia are 1917 style.
