HISTORY



Detailing the development and operational history of the Pfalz Dr.I Triplane Fighter Aircraft.  Entry last updated on 11/19/2016. Authored by Staff Writer. Content ©www.MilitaryFactory.com.
The triplane as a military aircraft held a short reign in the skies during World War 1 (1914-1918). Its design offered unprecedented maneuverability and handling in close-quarters which made them ideal gunnery platforms for dogfighting ventures. However, the battlecry of the air war soon returned to speed as the call of the day and triplanes quickly lost favor in the grand aerial campaigns of the First World War - leaving only a few successful designs in its wake. The Pfalz Dr.I was developed by Pfalz Flugzeugwerke of the German Empire during the height of triplane interest but it proved unreliable enough to limit its production to just ten aircraft which served from April 1918 on.

The aircraft was given a typical tri-winged arrangement which retained the upper and lower wing sections of a conventional biplane but added a third element sandwiched between the two existing planes. The wings were all braced by a thick strut arrangement which created single bays to each side of the fuselage. The fuselage was well-rounded and therefore quite streamlined with the engine encased in metal at the nose and driving a two-bladed propeller unit. Machine guns (2 x 7.92mm LMG 08/15) were fitted over the nose and synchronized to fire through the spinning blades with the pilot's open-air cockpit just aft of the guns (and under / behind) the upper-most wing element. The tail unit incorporated the usual single tail fin (rounded) and low-set horizontal planes. The undercarriage was of a tail-dragger arrangement with the main legs wheeled and fixed in flight. A tailskid brought up the rear.

Dimensions included a length of 5.5 meters, a wingspan of 8.5 meters and a height of 2.7 meters. Empty weight was 1,125lb against a MTOW of 1,555lb. Power was had from a Siemens-Halske Sh.III 11-cylinder, geared rotary engine of 160 horsepower which could propel the aircraft to speeds of 118 miles per hour up to a ceiling of 19,680 feet. Flight time was about 1.5 hours.

On looks alone the aircraft should have been a proper contender to claim air supremacy from Allied offerings of the day but the choice of engine fit made for an unreliable product in the end. Formal evaluations of the aircraft noted its lack of speed in addition to the temperamental engine and this led to a small batch of just ten aircraft being procured and fielded during 1918. The war was over with the November Armistice and this Pfalz triplane attempt subsequently fell to aviation history.
