The RWD-13 was a Polish touring aircraft developed by the Warsaw-based manufacturer RWD in the mid-1930s .
development
Rogalski and Drzewiecki constructed the RWD-13 as the successor to the RWD-6 and RWD-9 , which had been specially developed for the Challenge de Tourisme International in 1932 and 1934 , respectively. Like this, the RWD-13 was a strutted shoulder- wing aircraft with a rigid landing gear and slats . For the purpose of use as a touring aircraft, however, a weaker drive and places for two passengers were provided.
The first flight took place on January 15, 1935 and resulted in a number of orders. In addition to the main part of the RWD-13 produced for Polish aero clubs, around 20 aircraft were exported. They flew u. a. in Brazil, Estonia, Yemen, Austria, the USA and Venezuela. One copy was given to the Shah of Persia as a birthday present from the Polish government. Four planes flew liaison missions on the side of the Franco troops in the Spanish Civil War . Two RWD-13s ( VQ-PAL and VQ-PAM ) were purchased in 1939 from the Palestine-based Aviron company that used them for pilot training. As recently as 1948, you flew missions on the side of Israel during the Palestine War. After the attack on Poland began , a number of RWD-13s were requisitioned by the Polish army. In the further course of the war, about 25-40 aircraft were withdrawn from German access by being transferred to Romania. 21 survived the end of the war there and four of them were then returned to Poland, which they used for a few years.
In 1937 fifteen copies of the medical version RWD-13S appeared . Yugoslavia produced both the RWD-13 and the RWD-13S under license.
One RWD-13 is located in the Polish Aviation Museum and one in the Museu da TAM in São Carlos , Brazil.
