MARK D I Germany
The Markische Flugzeugwerke of Golm in der Mark was established in 1916 for aircraft repair, the training of military pilots and the eventual licence manufacture of training biplanes. In 1918, Ing Wilhelm Hillman left the Schutte-Lanz organisation to join the Markische Flugzeugwerke, for which he designed a single-seat fighter, the Mark D I, powered by a 195 hp Benz Bz IIIb water-cooled eight-cylinder Vee engine. The D I was scheduled to participate in the second fighter competition at Adlershof in May 1918, but the first prototype was destroyed in a crash prior to the contest. A second prototype, on which the warping of the lower wing surfaces was allegedly to have been replaced by conventional ailerons, was under construction in September 1918, but work was apparently terminated with the end of hostilities. No data are available apart from a time of 14 min to climb to 16,405 ft (5 000 m).
