The Euler D.I first flew in late 1916. It was powered by an 80 hp engine with the Euler patented machine gun on the front. ==Operational history== Two prototypes were recorded as being in service at the front in October 1916, and the German government ordered 50 in the same month. A further 50 were ordered in early 1917, but this order was largely transferred over to the D.I's successor, the [Euler D.II](/source/Euler_D.II). The plane saw very little combat service, being largely used as a fighter trainer for the remainder of the war. ==Operators== ;{{flag|German Empire}} *[Luftstreitkräfte](/source/Luftstreitkr%C3%A4fte); ==Specifications== {{Aircraft specs |ref= |prime units?=met |crew=1 |length m=8.1 |length note= |span m=13 |span note= |height m=2.66 |height note= |wing area sqm=13 |wing area note= |aspect ratio= |airfoil= |empty weight kg=380 |empty weight note= |gross weight kg=600 |gross weight note= |max takeoff weight kg= |max takeoff weight note= |fuel capacity= |more general= |eng1 number=1 |eng1 name=[Oberursel U.0](/source/Oberursel_U.0) |eng1 type=7-cylinder air-cooled radial piston engine |eng1 hp=80 |eng1 note= |prop blade number=2 |prop name=wooden fixed-pitch propeller |prop dia m= |prop dia note= |max speed kmh=140 |max speed note= |cruise speed kmh= |cruise speed note= |stall speed kmh= |stall speed note= |never exceed speed kmh= |never exceed speed note= |range km= |range note= |combat range km= |combat range note= |ferry range km= |ferry range note= |endurance= |ceiling m= |ceiling note= |g limits= |roll rate= |climb rate ms= |climb rate note= |time to altitude={{cvt|2000|m}} in 12.5 minutes |wing loading kg/m2= |wing loading note= |fuel consumption kg/km= |power/mass= |more performance= |guns=1 x engine-mounted 7.92-mm machine gun}} == References == {{reflist}} {{Nieuport V-strutters}} {{World War I Aircraft of the Central Powers}} {{Idflieg D-class designations}} Category:1910s German fighter aircraft Category:Sesquiplanes Category:Rotary-engined aircraft Category:Aircraft first flown in 1916 --- Adapted from the Wikipedia article [Euler D.I](https://en.wikipedia.org/wiki/Euler_D.I) by Wikipedia contributors ([contributor history](https://en.wikipedia.org/wiki/Euler_D.I?action=history)).
