Army Cooperation Plane","description":"The Lublin R-XIII was the Polish army cooperation plane, designed in the early-1930s in the Plage i Laśkiewicz factory in Lublin. Since 1927, they started working on their own prototypes. Those were designed by J. Rudlicki and his team of more than a dozen people including engineers Marian Bartolewski, Jerzy Dąbrowski, Antoni Uszacki, Janusz Lange, Jerzy Teisseyre, Witold Grabowski, Jaworski and others.   The factory’s first own product was a reconnaissance bomber Lublin R-VIII built in 1928. Its airliner variant, the R-IX, was constructed in a short while. In 1930, they produced a pilot series of 5 Lublin R-VIIIs, 3 of which were converted to seaplanes in 1932. At the beginning of 1929, they performed a test flight of a liaison aircraft prototype designated R-X; a pilot series composed of 5 examples was built in 1931. Prototypes of the Lublin R-IX airliner (1929) and Lublin R-XI airliner (1930) as well as its improved variant, the R-XVI, failed to meet the requirements of LOT Polish Airlines so the production was not started. However, 5 examples of an air ambulance variant R-XVI were built in 1933-1934. In 1931, they created the R-XII sport aircraft that was not put to use.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ GARDNERS","offer_id":49738088448273,"sku":"NGR9788366148314","price":30.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/8366148319.jpg?v=1751159266","url":"https:\/\/www.worldofbooks.com\/products\/lublin-r-xiii-army-cooperation-plane-book-andrzej-glass-9788366148314","provider":"World of Books ","version":"1.0","type":"link"}
