Euler Hydro-Triplane

A pre-war (1913) model was the Euler Hydro-Triplane a pusher configuration amphibious triplane flying boat featured in the French magazine L’Aérophile. It was propelled by a 70 hp engine Gnome engine, and was made famous also by the Magazine Flight as the best of its kind, this time powered with a 100 hp (75 kW), nine cylinder Gnome Delta rotary engine. It was remarkably the first true amphibian, with the mainwheels placed on the upper and lower pairs of struts. It was never used by the Military.

Euler-Voisin

In October 1908 August Euler founded the Euler-Werke in Frankfurt and managed to negotiate a license agreement with the Voisin brothers. In 1909 he created a factory at Griesheim Airport and started large scale aircraft production. The first few machines built were similar to Voisins, but Euler was not pleased with the original design and soon started to modify the construction, for example by lightening it, redesigning the landing gear and introducing ailerons.

Euler qualified for German pilot’s licence No. 1 on December 31st, 1909. Prince Heinrich of Prussia took his pilot’s certificate on an extensively modified example of the type. At least 30 other Germans learned to fly on this aircraft.
