PZL.3
The PZL.3 was a Polish four-engine monoplane heavy bomber project designed by Władysław Zalewski in 1928-1930 at Państwowe Zakłady Lotnicze.[1]
Design and development
At the time of the formation of PZL the Polish Department of Aeronautics gave the new design office the task of designing a heavy bomber. Zalewski drew heavily on his 1924 WZ-IX Pteranodon bomber and during the winter of 1928-29 the detailed design took shape. He proposed a large low-wing cantilever monoplane with four our Template:Cvt Bristol Jupiter engines in push-pull tandem nacelles over the wings mounted on pylons. A semi-monocoque stressed skin fuselage was to have its structural members and skinning be in Duralumin. The PZL.3 would have had twin fins and a fixed trousered tail-wheel undercarriage. Armament would have included 3 machine-guns and up to Template:Cvt of bombs.[1]
Due to the dire economic situation at the start of the 1930s and the substantial cost and risk, funds for a prototype were not forthcoming and the project was dropped.[1] After this, Zalewski left PZL and subsequently refused to work on Government sponsored projects.[1]
