Neuware - The D.XV was last of the series of biplane fighters and notably different from their earlier aircraft, with both mainplanes clear of the fuselage and without flying wires. The lower wing was the smaller of the two both in span and chord and had elliptical tips. The upper wing was square tipped and fitted with ailerons. Both were single piece from tip to tip. Outward leaning N-form struts defined the D.XV as a single bay biplane; groups of short struts from the mid and upper fuselage joined it to the upper wing and similar groups attached the lower plane.The D.XV had a 185 hp (138 kW) 6-cylinder water-cooled inline engine BMW IIIa with a rectangular radiator filling the upper nose above the drive-shaft of the two blade propeller. Aft, the fuselage was rounded in cross-section with the single open cockpit behind the upper wing's trailing edge. The horizontal tail was mounted at mid-fuselage, D-shaped in plan and with balanced elevators. The fin was triangular and carried a short, curved, balanced rudder. The D.XV's fixed conventional undercarriage was of the fixed axle type, the axle ends supported on pairs of V-struts and wire cross-braced; there was a tall tail skid. Armament, twin Spandau machine-guns.The D.XV was developed over the summer of 1918 and versions with unbalanced ailerons (D.XVf) and overhung, balanced ailerons (D.XV (Spezial). The 180 hp (134 kW) Daimler DIIIa engine was also considered. The Pfalz took part in the third D-type, held in October 1918. It was judged to have high performance and manoeuvrability though tail heavy and hard to land. It was one of the last German fighters accepted for production, getting its type approval on 4 November 1918, just a few days before the Armistice. Because it was approved for production so late, the Pfalz XV never reached operational status. Nonetheless, several were built and finished, and there were 74 completed fuselages in the Pfalz works when these were inspected by the Allies in the autumn of 1919. …
