The LVG D.IV was a German fighter plane built by LVG in World War I.

Design

The D.IV was similar to the D.III in having a plywood covered semi-monocoque fuselage, but the 195hp Benz Bz IIIb V-8 direct drive engine allowed for a cleaner nose than the NAG C III engine of the D.III. It retained the single axle main undercarriage of the D.III and had a similar tail structure. The D.IV was a single bay biplane with V struts between the wings. It used landing and flying wires. Both wings were straight edged and equal chord. The upper wing had straight edges, a wider span and wider chord, the lower wing had curved tips. The pilot's cockpit was below the rear half of the upper wing, with a curved cut-out for the pilot.^[1]

Development

The first prototype of the D.IV was destroyed in a flight on 5 January 1918, when the crankshaft broke in flight, creating a fire. The second prototype made it to the first of the D-type fighter competitions at Adlershof, but was lost on 29 January 1918 when the engine caught fire, destroying the aircraft. Because both prototypes were destroyed in crashes, the D.IV program was axed.

The Hansa Brandenburg W.27 and W.32 were prototype fighter floatplanes developed in parallel in Germany during World War I. They were developments of and intended replacements for the W.12 then in service and differed from each other principally in the choice of powerplant, the W.27 with a Benz Bz.IIIb and the W.32 with the same Mercedes D.III that the original W.12 used.

The Aviatik D.III was a German prototype single-seater fighter plane from the First World War, designed by Aviatik. It became the basis for the Aviatik D.IV and Aviatik D.V. In November 1917, the plane was first flown, using a 195 hp Benz Bz IIIbo gearless engine. It was of similar design to the Aviatik D.II, and was armed with two LMG 08/15 machine guns. After several tests at Adlershof from February 9–12, 1918, the plane underwent modifications, as requested by the Idflieg. In April, a second prototype, powered by a Benz Bz IIIbm, although several D.III powered by the original IIIbo engine were already under production; however, none of them were ever completed.
