German Fokker Dr. I triple-lobe fighter plane from the First World War. The work of Anthony Fokker and Reinhold Plat. The plane was a German response to the appearance of the British Sopwith Triplane fighter. The Fokker Dr.I was characterized by fantastic maneuverability, a very high rate of climb, and achieved a decisive advantage in wheel combat with biplane planes. However, it had a low top speed (165 km / h), which was partly also due to the use of a weak 110 HP engine. The first pre-production vehicles (marked with the symbol V.5) were tested by eminent German pilots: Werner Voss and Manfred von Richthofen, nicknamed the "Red Baron". It was the latter who made this model of aircraft famous, winning many victories on it. Serial Fokker Dr. I planes served at the front from October 1917. until the end of the war. A total of 320 units were produced. Technical data: Top speed: 165 km / h; climb speed 5.7 m / s, maximum ceiling 6095 m, armament: two 7.92 mm Spandau machine guns, firing through a propeller.
Albatros DV is a biplane of wooden structure with the front part of the fuselage, covered with aluminum sheet. The DV version did not differ much from its predecessor, the D.III series, mainly in terms of the fuselage section - the DV had an elliptical hull, which made it lighter by about 50 kg. The construction of the aileron drive was solved differently. These small changes seemed so small that the new aircraft was not even tested. The construction of the 1,5-wing aircraft, as in Nieuport, required a light aircraft. The inline albatrosses were too heavy for that. When recovering the aircraft from a dive flight, the lower lobe of the DV tended to break off frequently; this disadvantage was not eliminated by the end of the war. The D.Va version was stronger, but also heavier. About 900 Albatros DV series aircraft were built. Technical data: Maximum speed: 186 km / h; climb speed 4.2 m / s, ceiling practical 5700 m, armament: two 7.92 mm LMG08 / 15 machine guns.
