The Albatros D.III (factory designation L25) of the Albatros Flugzeugwerke was a fighter aircraft that was used by the German , Austro-Hungarian and Turkish-Ottoman air force during the First World War . The Albatros D.III was one of the most widely used German fighters. In Austria-Hungary , the aircraft was rebuilt as the Oeffag D.III with a few changes .

development

At the end of 1916, the Air Force Inspection provided the German aircraft manufacturers with a captured Nieuport single-seater ; This French combat biplane was regarded by German pilots as a particularly dangerous opponent in terms of turning characteristics and maneuverability. While some manufacturers largely copied the design of the Nieuport, the team of the chief engineer of the Albatroswerke, Robert Thelen , only adopted the design feature of a narrower lower wing. The aim was to significantly improve the pilot's view and the flight characteristics that are so important in aerial combat, such as maneuverability in turns and climbing ability , without sacrificing the proven firepower and stability of the Albatros D aircraft.

This change, however, required the reconstruction of the entire structure: the trailing wing edges with the ailerons were lengthened slightly outwards and the leading edges were shortened inwards. As with the Nieuport 11, the lower surfaces became shorter than the upper ones. They were only constructed with a single spar and the two wings were connected by V-struts. After the first flight in the summer of 1916, the type test took place on September 26, 1916.

With its synchronized twin machine guns , the D.III had the same firepower as its predecessor and was therefore still superior to the opposing fighters.

The aircraft was manufactured by the Albatros-Werke in Berlin-Johannisthal and the Ostdeutsche Albatros-Werke (OAW) in Schneidemühl . In the course of production, some changes were made to the aircraft, which were also carried over to the later Albatros DV . These included the rounding of the vertical stabilizer and the lateral offset of the Teeves & Braun wing cooler, in order to protect the pilot from scalding from hot coolant if he hits the cooler.

commitment

When the first 13 D.III reached the front in January 1917, their climbing ability and maneuverability made them superior to the Allied aircraft. In March 1917 137 D.III were already in use, in May 327. The albatrosses won the air superiority and maintained it throughout the spring, when almost all of the 37 fighter squadrons were equipped with D.III. In the bloody April 1917, the British alone lost 151 aircraft with only 30 German losses.

However, a dangerous design weakness came to light in use: The narrow, single-spar lower wings were designed too weakly, and so vibrations occurred during high loads when falling and turning, which could result in fluttering, breaking wings or completely losing the lower wings . In this way, two fighter pilots of Jasta 2 lost their lives on January 24, 1917, and the leader of Jasta 11, Manfred von Richthofen , was only able to save himself with difficulty by making an emergency landing after the lower wing broke. This deficiency was never completely rectified and was even more pronounced in the successor Albatros DV; In contrast to their German colleagues, the Austrian engineers who rebuilt the Albatros D.III as Oeffag D.III for the Austro-Hungarian aviation troops under license and continuously improved over three series, succeeded in solving this problem.

However, as more and better Allied fighters appeared in the sky, including the SPAD S.VII and the Sopwith Triplane , the D.III was replaced from July 1917 by the more powerful Albatros DV . In November, however, there were still 446 D.III's in the west, in Palestine and in the Balkans, while the enemy with the even more powerful fighters SE5 , Sopwith Camel and the SPAD S.XII were already the next generation of superior single-seaters in superior numbers Sent battle. The Albatros D.III remained in use until the end of the war.

In addition to the German air force, the Turkish air force successfully deployed the Albatros D.III. However, the Oeffag D.III series 53.2, 153 and 253 with 185, 200 or 225 hp Austro-Daimler engines, produced by Oeffag for the Austro- Hungarian aviation troops, proved to be the best .

After the end of the war, the D.III - mainly Oeffag D.III , from the holdings of the dissolved kuk aviation troops - was used on the Polish side in the Polish-Soviet war .

Aircraft in the front line

From January 1917 to around summer 1917, the Albatros D.III successively replaced almost all other types of fighter aircraft; a total of 1,340 machines had been built by the beginning of 1918

The German hunting squadrons reported the following stocks:

Further development

With the Albatros D.III and the Zeppelin LZ 80 / L 35, attempts were made in 1918 to use the aircraft as a subsidiary of an airship.
