LVG B types
The LVG B-types of the airline (LVG) were two-seat reconnaissance and training aircraft of the German Air Force in the First World War .
development
The LVG BI (works name D.IV) was created in 1912 as one of the first own designs by the Swiss engineer Franz Schneider, who transferred from Nieuport to the LVG . The two-handled biplane was produced in large numbers in 1913/14 and served as a training aircraft , but was also produced and used as a reconnaissance aircraft at the beginning of the war . The Otto company also participated in the production as a licensee , while August Euler built the model under the name Euler BI .
As a successor model, Franz Schneider designed the LVG B.II (factory name D.VI), also a two-legged double-decker, but with smaller overall dimensions. The motorization with the Mercedes DI engine with 105 hp was initially retained, but the flight performance remained inadequate, and so later machines were also equipped with the Mercedes D.II engine with 120 hp. LVG shared the production with the licensees Otto and Schütte-Lanz .
The LVG B.III appeared in 1917 and was intended as a training aircraft from the start. The aircraft was also built under license by Schütte-Lanz. The training aircraft Euler B.II and Euler B.III with 120 hp Mercedes engines built in 1918 by Euler-Flugmaschinenwerke were also replicas of LVG B.III.
commitment
The flight performance of the pre-war aircraft LVG BI turned out to be insufficient for military use, so the machines were soon removed from the front and used for pilot training. The B.II was also unsatisfactory and was later used for training purposes.
In November 1915, 12 machines were delivered to the Bulgarian Air Force .
Further development
Based on BI and B.II, Franz Schneider designed the armed reconnaissance aircraft LVG CI and II .
