Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The PWS-20 was a Polish single-engine high-wing passenger aircraft for 6 passengers, built in PWS factory in 1929, that remained a prototype. It was the first Polish passenger plane. The aircraft was developed for a contest for an airliner for LOT Polish Airlines, announced by the Polish Ministry of Communication in 1927. The best design was PWS-20, developed by Zbys aw Cio kosz. A prototype was built and flown on 12 March 1929 in Bia a Podlaska. It was next bought by the Ministry of Communication for evaluation (it was also known as PWS-20T, T for transport). In 1930 the plane was modified, with wider landing gear base and improved engine's cooling and exhaust systems and passenger cabin. After modifications it was designated PWS-20bis and received markings SP-AAZ. In 1930 the second prototype of PWS-20bis was built for the same user (markings SP-AAY).show more
