The Albatros BI (also called Albatros military biplane in contemporary sources ) was a German military aircraft. It was designed as a reconnaissance aircraft and flown as such in the Air Force until 1915 , the internal factory designation was L-1. When the First World War broke out, a military designation system was introduced, and the model was now called Albatros BI. Phönix Flugzeugwerke built the aircraft under license for Austria-Hungary .
construction
With the well -engineered half-shell wooden fuselage constructions by chief engineer Hugo Grohmann , Albatros had low-weight and high-performance fuselage constructions. In 1913, Ernst Heinkel and Robert Thelen developed the Albatros DD ( double decker , later military name Albatros BI ) as the most important type on this wooden hull base . The landing gear consisted of a fixed two-wheeled main landing gear with a continuous axle and a tail spur. Braking was done with a hook attached to the chassis axis. There was also a floatable version, the Albatros WDD (W.1).
Versions
The machine was equipped with Mercedes engines of 75, 100 and 120 hp, which drove a fixed two-bladed wooden propeller. The wingspan varied. Depending on the span, there were versions with a pair of handles (Albatros racing double decker) as well as two and three pairs of handles.
use
In 1914, the BI was able to set a height record. From July 10th to 11th, 1914, the Albatros works pilot Reinhold Böhm set the world record for endurance flights with a flight duration of 24 hours and 10 minutes. The altitude and endurance flight records were set with the three-pair version.
Because of its inferiority to Allied fighters , the aircraft was withdrawn from active service at the front in 1915 and served as a training aircraft until 1918 .
