Design and Development
In April 1917, Albatros received an order from the Idflieg (Inspektion der Fliegertruppen) for an improved version of the D.III. The resulting D.V prototype flew later that month.
The D.V closely resembled the D.III and used the same 127 kW (170 hp) Mercedes D.IIIa engine. The most notable difference was a new fuselage which was 32 kg (70 lb) lighter than that of the D.III. The elliptical cross-section required an additional longeron on each side of the fuselage. The vertical fin and tailplane remained unchanged from the D.III. The prototype D.V retained the standard rudder of the Johannisthal-built D.III, but production examples used the enlarged rudder featured on D.IIIs built by Ostdeutsche Albatros Werke (OAW). The D.V also featured a larger spinner and ventral fin.
The upper wing of the D.V was repositioned 4.75 inches closer to the fuselage, while the lower wings attached to the fuselage without a fairing. The wings themselves were almost identical to those of the standard D.III, except for a revised linkage of the aileron cables, which were contained entirely in the upper wing. Idflieg therefore conducted structural tests on the fuselage, but not the wings, of the new aircraft.
Early examples of the D.V featured a large headrest, which was usually removed in service because it interfered with the pilot's field of view. The headrest was eventually deleted from production. Aircraft deployed in Palestine used two wing radiators to cope with the warmer climate.
Idflieg issued production contracts for 200 D.V aircraft in April 1917, followed by additional orders of 400 in May and 300 in July. Initial production of the D.V was exclusively undertaken by the Johannisthal factory, while the Schneidemühl factory produced the D.III through the remainder of 1917.

Famous quotes containing the words design and/or development:
“Nowadays the host does not admit you to his hearth, but has got the mason to build one for yourself somewhere in his alley, and hospitality is the art of keeping you at the greatest distance. There is as much secrecy about the cooking as if he had a design to poison you.”
—Henry David Thoreau (1817–1862)
“There are two things which cannot be attacked in front: ignorance and narrow-mindedness. They can only be shaken by the simple development of the contrary qualities. They will not bear discussion.”
—John Emerich Edward Dalberg, 1st Baron Acton (1834–1902)
