The RWD-19 was a Polish two-seat low-wing sports plane of 1938, constructed by the RWD bureau, built in a single unit.

Development

The RWD-19 was designed in 1937-1938 in the RWD bureau. The chief designer was Jerzy Drzewiecki. Designer Tadeusz Chyliński designed the wing. [Andrzej Glass (2003). "Słownik biograficzny techników polskich", SBTP: Warsaw, p. 24: fragment of its entry about Tadeusz Chyliński: ( _pl. W 1937 r. podjął prace w Doświadczalnych Warsztatach Lotniczych (RWD) jako konstr., jednocześnie kontynuowal studia. Pracował przy dok. seryjnej samolotu obserwacyjnego RWD-14 Czapla, następnie zaprojektował plat samolotu zawodniczego RWD-19, kadlub samolotu dyspozycyjnego RWD-18, łoże silnika do samolotu szk. RWD-23 i dźwigar płata samolotu myśliwskiego RWD-25. W l. 1933-38 byl czl. Sekcji Lotniczej Kola Mechaników Stud. PW.)] The aircraft was designed specially in order to beat world records of distance in light aircraft category, under influence of French Caudron sports planes.

The prototype was built and first flown in October 1938 (registration SP-BPD). In winter it was evaluated by the Aviation Technical Institute in Poland. It was rather difficult to fly. There were no plans of serial production. The plan of beating a record was abandoned, because the German Arado Ar 79 had made it in a meantime. Probably the single aircraft was destroyed during air raids on the DWL factory after the outbreak of World War II.

Description

Mixed construction low-wing cantilever monoplane, conventional in layout, with a fixed landing gear and a closed cockpit. Steel framed fuselage, covered with canvas on a wooden frame, aluminum in front engine section. Three-part trapezoid wings with rounded tips, of wooden construction, two-spar, plywood (in front) and canvas covered, fitted with split flaps and slats. Conventional cantilever empennage, plywood (fins) and canvas (elevators and rudder) covered. Two seats in tandem, under a canopy, with a fixed panoramic windshield and small side windows. Behind the cockpit was a place for a baggage. Conventional fixed landing gear with a rear wheel, the main gear was in covers. 4-cylinder straight engine de Havilland Gipsy Major in front, driving a two-blade tractor wooden propeller Szomański of a fixed pitch. Fuel tanks 180 l in mid-wing section. Cruise fuel consumption 28 l/h.
