Argus As 410

The Argus As 410 was an air-cooled continuous 60 ° twelve-cylinder V-engine of the company Argus. The engine became necessary after a small but powerful drive was required as the Argus As 10 by the Reich Air Ministry (RLM). Air cooling was retained, as the only way to power to weight ratio could be kept low. In order to better dissipate the heat, the cylinder heads were rotated by 45 °. For this purpose, the bumpers had to be tilted and crossed out, to actuate the valves hanging. The cylinder heads were screwed on the cylinders with fine thread. The Argus-410/411-Motoren were the last aircraft engines with carburetors that have been developed in the German Empire until 1945.

The reduction gear for the propeller shaft was a planetary gear with a reduction ratio of 0.67. To improve the performance over the AS 10 with almost the same displacement, a via spur gears driven by the crankshaft spin loader was installed. The development was started from 1936 and completed in 1938. From the series AS 410/411 until the war ended about 14,000 units were manufactured.

Built- they were, among others, in the Arado Ar 96B, the Focke -Wulf Fw 189, the Henschel Hs 129, the Siebel Si 204 A, and the Pilatus P -2.

The engine was further developed into the Argus As 411 later.
