Lotnicze Warsztaty Doświadczalne (abbreviated as LWD) was a Polish aerospace manufacturer and design office based in Łódź, operating from 1945 until 1950. The title translates to Aircraft Experimental Workshops. It holds the distinction of being the first Polish aerospace design bureau established after World War II.
History
The devastation caused by World War II and the subsequent German occupation obliterated Poland’s aviation sector. Following the liberation of eastern Poland, a group of engineers convened in Lublin in October 1944 to form a Design Bureau under the Ministry of Communication. Aleksander Sułkowski led this bureau, with Tadeusz Sołtyk serving as the chief designer. Despite limited resources, they initiated development on a utility aircraft named Szpak-1. Early in 1945, this design office relocated to the recently liberated city of Łódź. On April 1, 1945, it was officially established as the Aircraft Experimental Workshops (LWD), functioning under the Ministry of Communication.[lower-alpha 1]
Although the Szpak-1 never reached production, LWD succeeded in designing and constructing its successor, the LWD Szpak-2 utility plane. This aircraft achieved its maiden flight on October 28, 1945, marking it as the first Polish plane flown after the war. Only prototype units of both Szpak-2 and Szpak-3 were completed; however, in 1947, PZL-Mielec manufactured ten units of the Szpak-4—the first post-war Polish aircraft to enter series production.
In the same year, LWD developed the LWD Żak, a two-seat touring and training aircraft. By 1948, LWD had produced a batch of ten Żak-3 planes along with prototypes for Żak-1, Żak-2, and Żak-4 variants.
The most notable achievement from LWD was the military and civilian trainer known as the LWD Junak, introduced in 1948. Enhanced versions—Junak-2 and Junak-3—were manufactured starting from 1951 at the WSK-4 Okęcie facility in Warsaw, totaling 252 units. However, further advancements on this model occurred outside LWD’s scope. The LWD Zuch, also from 1948, was a civilian aerobatic and training aircraft derived from the Junak design. Despite its success, only seven were produced at LWD due to engine availability limitations.
Additionally, LWD created a twin-engine light transport aircraft called the LWD Miś in 1949; nonetheless, it failed to achieve success and did not enter production. The final project from LWD was the LWD Żuraw, a two-seat military liaison and utility high-wing prototype completed in 1951, which likewise remained unproduced.
In 1950, LWD transitioned from a design and experimental workshop into a manufacturing plant renamed WSK-6 (Wytwórnia Sprzętu Komunikacyjnego 6, meaning Communication Equipment Factory 6). This change effectively ended its original mission and soon after led to its dissolution due to limited production capacity. Subsequently, chief designer Tadeusz Sołtyk established a new design bureau within the Aviation Institute located in Warsaw.

Footnotes
- ↑ The Polish name of this entity roughly corresponded to Doświadczalne Warsztaty Lotnicze, a pre-war manufacturer associated with RWD aircraft.
- ↑ Despite being an LWD design, only three units were actually constructed by LWD; the remainder were produced by other manufacturers.
- ↑ Although designed by LWD, all but one aircraft were manufactured by external producers.
