From Wikipedia, the free encyclopedia
The de:Kommandohilfsgerät 35, Kommandogerät 36, and de:Kommandogerät 40 are analog fire control computers used by the German armed forces during WW2 to direct their heavy 88 mm, 105 mm, and 128 mm anti-aircraft (FlaK) guns.[lower-alpha 1]
The Kommandohilfsgerät 35 uses an angular speed method to arrive at a computed firing solution. The Kommandogeräte 36 and 40 operated on the linear speed method, using present azimuth, present angular height, and present slant range as basic inputs; the firing solutions were sent electrically to each individual gun in a battery of four.[1]
