Doświadczalne Warsztaty Lotnicze (DWL) (Experimental Aeronautical Workshops) was the Polish aircraft manufacturer, active in 1933-1939. It was a home of the RWD construction team and manufactured aircraft under a brand RWD.


The RWD construction team was organized of students of Warsaw University of Technology around 1928. They built their first designs in workshops of the Aviation Section of Students' Mechanical Club, in University buildings. In 1930 the workshops moved to new buildings near Okęcie airport in Warsaw, founded by the LOPP organization. In March 1933 the workshops separated from the Aviation Section and the University, and there was created a company Doświadczalne Warsztaty Lotnicze to manufacture RWD aircraft.

Main designers were Stanisław Rogalski and Jerzy Drzewiecki of the RWD team, other designers were Bronisław Żurakowski, Tadeusz Chylinski, Leszek Dulęba and Andrzej Anczutin and several engineers, including Henry Millicer. A company director was Jerzy Wędrychowski.


First RWD designs manufactured in the DWL were the Polish basic trainer RWD-8 and the sports plane RWD-9 (the winner of Challenge 1934 international contest). Due to limited capabilities of DWL, only some 80 RWD-8s were made in the DWL, and about 470 licence-built in Podlaska Wytwórnia Samolotów (PWS). Also, a reconnaissance plane RWD-14 Czapla was licence-built in Lubelska Wytwórnia Samolotów (LWS) only.

The plane manufactured in biggest number in DWL was a touring plane RWD-13 (about 100). Other important designs were the RWD-10 aerobatic plane (1933), RWD-17 aerobatic-trainer plane (1937) and RWD-21 light sports plane (1939). World War II prevented further development and serial production of later RWD designs, and put an end to the DWL workshops.
