The P.Z.L. 3 was a Polish project for a four-engine heavy bomber, designed by Władysław Zalewski from 1928-1930 at P.Z.L. (Państwowe Zakłady Lotnicze - National Aviation Establishments).[1]
Design and development
At the time of the formation of P.Z.L. the Department of Aeronautics gave the nascent design office the task of designing a heavy bomber. Drawing heavily on his 1924 WZ-IX Pteranodon bomber, Zalewski was given the task as designer. During the winter of 1928-29 the detailed design of the P.Z.L. 3 bomber took shape, emerging as a large aircraft powered by four 500 hp (370 kW) Bristol Jupiter engines mounted in tandem in nacelles on pylons above the wings. Due to the dire economic situation at the start of the 1930s and the expected hagh costs, funds for construction of a prototype were not forthcoming so the project was dropped.[1]
The P.Z.L. 3 would have been a low-wing cantilever monoplane with four engines in push-pull tandem nacelles over the wings mounted on pylons. Built with a semi-monocoque stressed skin fuselage skinned with Duralumin skinning and structural parts,the P.Z.L. 3 would have had twin fins and a trousered fixed tail-wheel undercarriage. Armament would have included 3 machine-guns and up to 3,000 kg (6,600 lb) of bombs.[1]
After the P.Z.L. 3 was rejected Zalewski left P.Z.L. and refused to work on Government sponsored projects thereafter.[1]
