The AEG J.I was a German biplane ground attack aircraft of 1917, an armored and more powerful version of the AEG C.IV reconnaissance aircraft.^[1]

Design and development

The AEG J.I was a two-seat single-engined tractor biplane with a conventional landing gear with a tail skid. The aircraft was constructed using fabric covered steel tubes. The open tandem cockpit for the pilot and gunner had armour protection . The gunner had three weapons, two 7.92 mm (.312 in) LMG 08/15 machine guns were fitted to the floor of the cockpit for ground targets. One 7.92 mm (.312 in) Parabellum MG14 machine gun was on a rotable mounting.^[1]

Aircraft fitted with ailerons on the lower wing as well as the upper wing were designated AEG J.Ia.^[1]

An improved version of the J.I was developed as the AEG J.II, which had aerodynamically balanced ailerons with overhanging horn balances, extended rear fuselage with a larger fin to improve directional stability and a re-located aileron link strut.^[1]

After the war, several J.IIs served the first sustained daily passenger aeroplane service in the world, between Berlin and Weimar, flown by Deutsche Luft-Reederei. This route began on 5 February 1919. Early commercial J.II's retained open cockpits, but modified versions with enclosed cabins for the two passengers quickly replaced them.^[2]

Variants

AEG J.I: An armoured version of the AEG C.IV fitted with downward pointing machine guns in the floor of the rear cockpit for ground strafing and a defensive hand-aimed machine-gun in the observers cockpit.^[1]
AEG J.Ia: The J.Ia version featured aileron controls on the lower wings, in addition to the upper.^[1]
AEG J.II: Structurally similar to the J.I the J.II introduced ailerons aerodynamically balanced by large horn extensions at the wing-tips, increased fin area to improve directional stability and a re-located aileron link strut.^[1]
