Fokker Dr.1 福克 Dr.I 戰鬥機
福克 Dr.I 戰鬥機是是德國王牌飛行員紅男爵里希特霍芬所駕駛的代表機種。1917 年起，福克 Dr.I 戰鬥機開始替代他曾駕駛用於英勇殺敵的信天翁D戰鬥機的地位。它深受英國索普威斯三翼機的設計影響，紅男爵在兩天內擊落兩架敵機後，認為據之生產的兩個原型和後來的預生產模型比 Sopwith 三翼機更好。
不久之後，維爾納·福斯少尉以其中一架預生產戰機中做到8次擊墜，因而帶來了300 架福克 Dr.I 的訂單。這種小型三翼戰鬥機的特點是機身、尾翼和方向舵由焊接鋼管製成，而機翼則以木材製成的輕量化空心箱樑建構而成。武器配備是兩把與螺旋槳同步的 8 毫米 Spandau 機槍，明顯優於較早期的設計。儘管Dr.I具有高機動性並具有極佳的爬升率，但與它的對手相比，Oberursel 出產的汪克爾引擎速度十分不理想，且還發生飛機在壓力下分解的災難性的機翼故障案例。由於這些缺點，Dr.I 被 Fokker D.III取代。
Known primarily as Manfred von Richthofen’s fighter of choice, the Fokker Dr.I of 1917 was ordered as a replacement for the poorly performing Albatross D.III fighter. After viewing a captured British Sopwith Triplane, Fokker was directed to build a similar triplane. The resulting two prototypes and later pre-production models were deemed superior to the Sopwith Triplane by Richthofen himself after he scored two kills in two days. Shortly after, Ace Werner Voss added 8 kills to his tally flying one of the two pre-production planes. This resulted in an order for 300 Dr.I’s. The diminutive three wing fighter featured a fuselage, tailplane and rudder made of welded steel tubing, while the wings were built around light weight hollow box spars. Armament consisted of two 8mm Spandau machine guns synchronised with the propellor. Although the Dr.I was highly manoeuvrable and had an excellent rate of climb, it was slow compared to its adversaries and some examples were plagued by catastrophic wing failures causing the aircraft to break up under stress. Due to these shortcomings the Dr.I was replaced by the Fokker D.III.
