O.Thetford, P.Gray German Aircraft of the First World War (Putnam)


A.E.G. DJ I
  This aircraft was designed as an armoured single-seat ground attack fighter, roughly equivalent to the British Sopwith Salamander. It first flew in September 1918, but the Armistice stopped further development. Braced with two bay I struts, it had no flying or landing cables. The fuselage was skinned with sheet aluminium. Engine, 195 h.p. Benz Bz IIIb vee eight, driving four-blade airscrew. Span, 10.0 m. (32 ft. 9 3/4 in.). Length, 6.69 m. (22 ft. 11 1/4 in.). Height, 3 0 m. (9 ft. 10 1/8 in.). Weights: Empty, 1,185 kg. (2,607 lb.). Loaded, 1,370 kg. (3,014 lb.). Speed, 180 km.hr. (112.5 m.p.h.). Climb, 1,000 m. (3,280 ft.) in 4 min.

A.E.G. DJ I Germany

  Pursuing the concept of the single-seat armoured ground attack fighter, A.E.G. had begun the development of an aerodynamically advanced biplane as a Panzer-Einsitzer before the initiation of flight testing of the PE triplane, and this, the DJ I, was to be flown in July 1918. Two prototypes of the DJ I were completed with the 195 hp Benz Bz IIIb engine and a third prototype with the 240 hp Maybach Mb IVa engine, armament standardising on twin synchronised 7,92-mm LMG 08/15 guns with provision for anti-personnel bombs. An equi-span two-bay biplane, the DJ I wing cellule dispensed with flying wires, interplane bracing being provided by I-section struts. The wings were of dural construction with fabric covering, and the fuselage, which embodied some armour protection for the engine, fuel tank and pilot, had sheet aluminium skinning. Hostilities terminated while flight testing of the DJ I was still in progress. The following data relate to the Benz-engined version.

Max speed, 112 mph (180 km/h).
Empty weight, 2,606 lb (1182 kg).
Loaded weight. 3.031 lb (1375 kg).
Span, 32 ft 9 3/4 in (10,00 m).
Length, 21ft 11 1/3 in (6,69 m).
Height, 9 ft 10 1/8 in (3,00 m).

AEG DJ.I Biplane

  Disappointed by the mediocre flight characteristics and low speed of the AEG DJ.I triplane, AEG engineers brought out a biplane version, the AEG DJ.I fighter, also powered by the 195 hp Benz Bz.IIIb V-8 engine. Sharing the triplane's armored fuselage design, the DJ.I had a wireless wing cellule to minimize damage from ground fire. The construction began in March and was completed in May 1918, but according to Idflieg it was not until August that the flight tests began. The reason for the delay is not known but may have been caused by unavailability of the experimental Benz V-8 engine. Converting to a biplane wing cellule improved the aircraft's speed and climb rate. In a 1920 aircraft inventory compiled by Luftfriko there were two AEG DJ.I aircraft listed as "property of the factory." Whether this referred to the DJ.I triplane and biplane or the second DJ.I fighter described below has not been determined.
  A second AEG DJ.I powered by a 245 hp Maybach Mb.IVa engine was under construction from May to July 1918. In September we learn that the Maybach engine was to be replaced by a new one, pointing to the probability that the second DJ.I had performed some flight trials.
  A third AEG DJ.I was reported under construction in September 1918, but there is no record of completion. That three DJ.I prototype fighters existed was consistent with the Idflieg policy of ordering one prototype for flight tests, one for static-load testing, and one held in reserve.

A.E.G. DJ I
J.Herris - AEG Aircraft of WWI /Centennial Perspective/
The AEG DJ.I biplane was well streamlined and was designed with thicker wings to enable wireless bracing, reducing drag. The 195 hp Benz Bz.IIIb V-8 engine drove a four-bladed propeller.
J.Herris - AEG Aircraft of WWI /Centennial Perspective/
The AEG DJ.I biplane was developed from the earlier DJ.I triplane to improve its performance and flight characteristics. It was powered by the same experimental 195 hp Benz Bz.IIIb V-8 engine, which likely delayed its development. The biplane use the same armored fuselage as the triplane coupled to thick biplane wings unlike those on any other AEG design of the war. The DJ I entered flight test in July 1918.
