Following the
Armistice of 1918, Germany continued to build aircraft and engines under the control of the
Military Inter-Allied Commission of Control. For use on very large aircraft, Argus designed and built the As 5 WW-24 water-cooled piston engine. The As 5 consisted of six banks of
cylinders arranged around a common
crankshaft with a single output shaft. Each cylinder drove the crankshaft through a master and slave big end, similar to most
radial engines. The top and bottom sets of three cylinder banks were set at 45° to each other with a 90° separation between the outermost banks. Individual cylinders with sheet metal water jackets shared the aluminium alloy heads, four to a bank. Inlet and exhaust valves were actuated by shaft driven
overhead camshafts. The aluminium alloy
crankcase was split top and bottom. Although some testing was carried out, the As 5 never flew and was abandoned along with the very large aircraft projects it was intended to power. ==Engines on display==
