Design and Development
The E.I was essentially an armed version of the Fokker M.5K single-seat reconnaissance aircraft(military designation A.III), which was in turn very closely based on the design of the 1913 French Morane-Saulnier Type H. Like the Morane, the Fokker was an externally braced mid-winged monoplane with a vertically tapered box section fuselage, with fully movable horizontal and vertical stabilizing surfaces, also known as "flying" surfaces, giving the pilot the usual tail control functions - roll control was achieved through controlled wing warping, as was conventional in contemporary monoplanes. Wing warping was achieved through external cables attached to the surface and running through a king post located in the front of the cockpit. The fuselage structure was fabric covered welded steel tubing - this constituted the biggest difference between the Fokker and the Morane, which had an entirely wooden framework. Welded steel tube provided the basis for the structure of all Fokker aircraft for many years.
This unremarkable and derivative design was, however, transformed into a formidable fighter when it was fitted with the newly-developed synchronizer gear, the Fokker Stangensteuerung, firing a single 7.92 mm (.312 in) Parabellum LMG 14 or Spandau LMG 08 machine gun through the spinning propeller. Indeed the first five E.Is had been ordered and were under construction as A.IIIs but were completed as M.5K/MG aircraft, retaining the earlier "shoulder-wing" placement of the A.III type. Subsequent production E.Is had their wings lowered slightly from the M.5's shoulder configuration, which improved pilot visibility. (These were designated by Fokker as the M.14 which was also used for the following two Eindecker variants.)
All Fokker E.I aircraft had a 68.5 l (18.1 US gal) capacity, single gravity fuel tank, located forward of the cockpit, with a fuel gauge protruding from the sheet metal upper nose paneling, usually offset slightly to port.

Famous quotes containing the words design and/or development:
“I begin with a design for a hearse.
For Christ’s sake not black—
nor white either—and not polished!
Let it be weathered—like a farm wagon—”
—William Carlos Williams (1883–1963)
“And then ... he flung open the door of my compartment, and ushered in “Ma young and lovely lady!” I muttered to myself with some bitterness. “And this is, of course, the opening scene of Vol. I. She is the Heroine. And I am one of those subordinate characters that only turn up when needed for the development of her destiny, and whose final appearance is outside the church, waiting to greet the Happy Pair!””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
