Argus As 410
The Argus As 410 was a German air-cooled inverted V-12 aircraft engine that was first produced by Argus Motoren in 1938.
Design and development
The engine marked a departure from earlier Argus engines in that it had new construction techniques which gave the engine greater operating speeds and power. The engine featured smaller 105 mm x 115 mm cylinders with deep finned steel cooling slots, aluminum heads, geared supercharger, a steel alloy crankshaft and a magnesium alloy crankcase. The engine weighed approximately and produced at 3,100 rpm. Approximately 28,700 engines were produced.A distinctive feature is the finned spinner ahead of the propeller. This is driven by the airflow as a windmill, and used to power the actuator of the variable-pitch propeller.
The more powerful and refined Argus As 411 was developed from it.
