In 1946, Wiktor Narkiewicz, who prior to the Second World War was technical director of the Czechoslovakian Avia aero-engine factory, was appointed chief designer of the Polish Central Engine Office, and later the Aero-engine department of the Polish Aviation Institute (Instytut Lotnictwa, IL). He led the design of the WN-1, a 48 kW (65 hp) air-cooled flat-four piston engine which was the first post-war Polish aero-engine, followed by the 213 kW (285 hp) WN-2 in 1947, but both of these engines failed to enter production.[1][2]
In 1952 Narkiewicz set up a small design team to design a new seven-cylinder radial engine, the WN-3. The first prototype, rated at 220 kW (300 hp) was completed in 1954, and by the time testing was completed in 1955, the engine's power rose to 250 kW (330 hp).[1][2] The WN-3 entered production in 1956,[3] powering the PZL TS-8 Bies training aircraft.[2]
The engine was produced in 1957-1960 by WSK-Kalisz in Kalisz,[4] it might be known also as PZL WN-3, or (in Western sources) as Narkiewicz WN-3.[3]
