{"product_id":"dornier-do-335-pfeil-a-marek-ry-9788366673786","title":"Dornier Do 335 Pfeil A","description":"In 1937, Dornier obtained a patent for a plane with two engines in the fuselage, driving the pull and push propellers. The design was marked P.59, and its concepts were refined in 1939 in the P.59-05 variant, after which the design was put in a drawer. This type of plane was not needed at the time. Nevertheless, limited experimental work was carried out, the result of which was a small Goppingen Go-9 plane, with an aerodynamic system obtained from P.59, as well as three-support landing gear with a front wheel and an engine driving a push propeller through a long shaft. The results of these experiments were used when designing the P.231 aircraft in several variants - also combining piston and jet propulsion. When in 1942 the RLM announced the requirements for a high-speed multipurpose aircraft, the equivalent of the British Mosquito, Dornier proposed the P.231 as a rather unusual answer. Despite the risks posed by the different P.231 concept, Dornier was commissioned to build several prototypes.","brand":"Kagero Oficyna Wydawnicza","offers":[{"title":"Default Title","offer_id":50377955705120,"sku":"9788366673786","price":16.1,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/2812\/7264\/files\/9788366673786.jpg?v=1780843708","url":"https:\/\/bookcorner.com\/products\/dornier-do-335-pfeil-a-marek-ry-9788366673786","provider":"The Book Corner","version":"1.0","type":"link"}
