The NFW E.I was a prototype fighter aircraft built in Germany during World War I.
Design
The E.I was an all-wood single-seat monoplane powered by an Oberursel U.0 rotary engine. The wing had two spars between which the pilot's seat was located, but also a plywood trim. One prototype was built and flown in 1917, but the type did not enter production.
