Recently spotted this engine in the krakow air museum, it was labeled as an Argus As 5. Its a 24 cylinder engine that seems to be 2 broad arrows rather than a radial, do they share a common crank shaft or one each? Does any one know what it was used in or any other info about it as my polish is non-existant.

Amazing piece of engineering – thanks for the photos. My (slightly technical) grey matter suggests to me that, as the opposing lines of cylinders are directly opposite, there was a single crankshaft. If I’m right it must be one helluva size!!

The sound of one of those would make a change at airshows that’s for certain. I reckon it would be so loud it’d have the noise abatement people three counties away complaining.

Excellent, thanks for the quick response!

Piotr Lopalewski, Chief Registry & Research Dept. at the Polish Aviation Museum, Krakow has provided the following information:
24-cylinder, water cooled “W”configuration; Maximum output: 1,119 kw (1,500 hp) at 1,800 RPM; Compression ratio: 5.6:1; Capacity: 94.1 liters (5,742 cu in); Weight: 1,100 kg (2,425 lbs).
The engine was probably envisaged for a big, single engine passenger plane. The designer was engineer Riedel–the same who designed the two-stroke starter engine for the Jumo 004 turbojet engine. Three prototype As-5s were built between 1924 and 1927. None were ever flown.
