The RWD-5 constructors

The RWD company founders and leading constructors began their aviation engineering design work from Warsaw University of Technology's Aviation Section of Mechanics Society (Sekcja Lotnicza Koła Mechaników Studentów Politechniki Warszawskiej) in 1922, even before Aviation Faculty was formed. They began from designing gliders, although the requirements and ways of receiving necessary stability and manouverability were not known for such aircraft. A few minutes-flights, limited to mountainous terrains, pilotage troubles and gliders technical imperfection did not satisfy the young students - they wanted to build engine-powered aircraft and fly them. The first airplane project of the Aviation Section came into being in 1925 - it was JD-1. It was built in the basement of New Drawing Office building (Nowa Kreślarnia) at Nowowiejska Street. The factory worked in such "partisan" circumstances till year 1930. Since 1930 the DWL factory was based in hangars and workshops next to the Okęcie airfield. The work of the three constructors was conducted fully collectively. All the matters - starting with the main idea of an airplane, ending with the technical details, were decided during collective councils. All the three constructors were flying pilots, they were taking part in the championships. Thanks to that, they knew the pilots' needs, requirements regarding stability, steerability, manouverability - all the RWD airplanes were ergonomic, adjusted to the air-crews' needs. In 1933 The RWD Ltd. under the name "Experimental Aviation Workshops" (Doświadczalne Warsztaty Lotnicze) was created, it was working in buildings leased from LOPP on Okęcie airfirld. During 6.5 years of work 16 airplane prototypes were constructed and built, additionally about 270 serial airplanes were built. The airplanes' technical development, factory manuals, technical requirements, maintenance manuals were very simplified and brief. It was possible thanks to high level of skills and responsibility of workerrs and mechanics of the factory. The factory didn't have any complicated assemly tools, workshops taking care of cockpit instruments, upholstery; the cloth airplanes coverings were far from the perfection... The constructors were scruplously avoiding accurate dimension tollerances, orifices positioning to allow the elements to fit during the final assembly - it was causing not-interchability or parts and assemblies among the pieces of the same airplane type, but it was accelerating the process of designing, constructing and assembling the airplanes.

Stanisław Wojciech Rogalski

(1904-1976), engineer pilot, graduate from Mechanical Faculty of Warsaw University of Technology (Wydział Mechaniczny PW). He was bringing the most of the aerodynamic matters and flight mechanics in RWD team. He was the most critical from the three, he was the best in tracing, finding and explaining the sources of not achieving or exceeding the anticipated properties of an airplane, he knew how to explain it theoretically. Prudence, quiet, kindness for all was characteristic for him. He shared his knowledge with the cooperators and students very willingly and in precise and clear way. Since 1939 in british Westlanda factories, in 1941 delegated to Turkey for reorganization of turkish aviation industry (THK factory). Since 1947 in USA, among others - Princeton Uniwersity professor.

Stanisław Wigura

(1901-1932), pilot and aviation engineer, graduate from Mechanical Faculty of Warsaw University of Technology (Wydział Mechaniczny PW), later he was the lecturer of the Warsaw University of Technology. He was spending the most of the time from the three of main constructors, on airplane calculations - its loads and strength. He was flying with cpt. F. Żwirko, among others: in 1929 on RWD-2 they made the trip around the Europe (5000 km, route: Warszawa-Erfurt-Paris-Barcelona-Wenecja-Warszawa), in 1932 on RWD-6 they won the international touristic airplanes championships Challenge in Berlin. They died in a flying accident the same year in Cierlicko (Czech).

Jerzy Drzewiecki

(1902-1976), engineer, pilot, graduate from Mechanical Faculty of Warsaw University of Technology (Wydział Mechaniczny PW). The most ingenous from three from the three of main constructors, in drawing the new solutions, the same for the whole aircraft and the details, he had a great designing intuition. He was raising the flowers in the laboratory, he was taking care of the garden surrounding theworkshops. Moreover, he was ski tourist, later canoe tourist. Til the early 1933 test pilot of all RWD produced airplanes. In 1932 he has set up the world airplane speed record on RWD-7. He was the contestant of the Warsw Flying Club. Since 1939 transport pilot in England. After the war he settled in Canada.

Jerzy Wędrychowski

He was Managing Director of "The Experimental Aviation Workshops" (Doświadczalne Warsztaty Lotnicze) and the whole RWD factory during 1927-1939 years . He created the organization form of the entire enterprise, he organized the easy terms of designers work ant the factory, he ensured the investors, he gained the friends (and unfortunately enemies. Mainly, thanks to him, the RWD team achieved what it achieved. During the war, thanks to him, almost all the RWD designers and engineers worked in the THK factory, which became the start of the aviation industry in Turkey.
