Albatros D.III: Johannisthal, OAW and Oeffag variants by James F. Miller

By James F. Miller

In 1916, Imperial German aerial domination, as soon as held by means of rotary-engined Fokker and Pfalz E-type wing-warping monoplanes, were misplaced to the extra nimble French Nieuport and British DH 2s which not just out-flew the German opponents yet have been found in better numbers. Born-from-experience calls from German fighter pilots asked that, instead of compete with the maneuverability of those adversaries, new single-engine machines might be built with greater horsepower engines and armed with , instead of the then-standard unmarried laptop weapons. The Robert Thelen-led Albatros layout bureau got to work on what grew to become the Albatros D.I and D.II and through April 1916 that they had constructed a swish but rugged laptop that featured the standard Albatros semi-monocoque wood development and hired a 160hp Mercedes D.III engine with energy sufficient to equip the aeroplane with forward-firing desktop weapons. visible hallmarks of the D.I and early creation D.II comprise fuselage fastened Windhoff radiators and matching chords for the higher and reduce wings.

Meanwhile, Albatros had already produced the prototype of the D.II's successor, the D.III. inspired via the French Nieuport sesquiplane layout, the D.III featured decrease wings of diminished chord and single-spar building, with the interplane struts now assembly the reduce wings in a 'V'. After arriving on the entrance en masse in early 1917, the Royal Flying Corps didn't own a fighter which could arrest the Albatros' onslaught opposed to the RFC reconnaissance machines and hence they suffered appalling casualties in a determined interval referred to as 'Bloody April'. although, regardless of the D.III's luck, the sesquiplane layout ended in structural flaws that ended in the deaths of a number of pilots, which prompted the sort to be grounded until eventually the decrease wings should be reinforced or changed. nonetheless, even after their go back to carrier, German pilots knew to not prosecute a dive too aggressively lest they invite structural catastrophe.

Always chasing functionality improvements, by the point of 'Bloody April' Albatros had already designed and obtained a construction order for the D.V.D.IIIs have been synthetic at the same time yet creation used to be shifted to the Ostdeutsche Albatros Werke (OAW) in Schneidmuhl, the place they obtained extra powerful development. They differed little from their Johannisthal D.III brethren externally, store for a marginally diverse dermis program at the nostril and a D.V-type rudder, which had a curved instead of directly trailing aspect. additionally they had Mercedes engines of a hundred seventy five hp, as opposed to the a hundred and sixty hp engines of the Johannisthal D.III. total they benefitted from the teething adventure of the sooner D.IIIs and refrained from the structural difficulties that resurfaced with the Johannisthal-built D.Vs.

In all, 500 D.IIIs and 840 D.III(OAW)s have been produced and observed heavy carrier all through 1917. They extracted a significant toll at the enemy yet because the 12 months improved confronted progressively more new enemy fighter kinds, together with the Sopwith puppy, Sopwith Triplane, SPAD VII, and SE5a, yet remained on the entrance in excessive numbers (446 of either kinds have been recorded on 31 October) till dwindling in spring 1918 (from 357 in February to eighty two in June) with the coming of the Fokker Dr.I and D.VII.

5. III(OAW) NOSE Similar to its Johannisthal brethren, including the nose footstep. The biggest differences were that its horizontal panel lines were situated differently and extended further aft, past the leading edge of the wing to the aft cabane connection point. The manufacturer and Idflieg placards were relocated to the fuselage near the cockpit, and the engine cowl panels featured a “crease” along their bottom edges. 6. III(OEF) NOSE Oeffag Albatros noses initially resembled those of German-built machines but gradually the spinner was removed, and ultimately the nose section redesigned into a rounded shape that somewhat resembles a modern submarine hull.

An altimeter and airspeed indicator could be present (the latter was an anemometer type and commonly but not exclusively located on an interplane strut) but these were retrofitted installations and not factory standard. The sole navigational instrument was a floor-mounted magnetic compass. This was a less than ideal location for navigating via precise headings but Albatros pilots did not conduct long-range A-to-B navigation often. Instead, they employed pilotage (using fixed visual ground references [roads, lakes, woods, railroads, villages] to guide oneself to a destination) for local short-range navigation over known territories and locales – they were hunting enemy airplanes in a familiar geographical area, not homing cross-country on distant locales across the horizon.

Close inspection beneath the point of the heart reveals a round footstep, a feature of first production-batch machines. 50 no help, as definitive color demarcations cannot be seen. It is likely that some part of its empennage was green, as perhaps was its spinner and front cowl panels, such as on other Jasta 11 machines, but the exact manner of application is yet to be determined. In any regard, Wolff attained 29 credited victories while flying an Albatros with Jasta 11. On May 4 he was awarded the Orden Pour le Mérite and two days later appointed as Jasta 29 Staffelführer.
