The Albatros L 58 was a single-engine airliner designed as a shoulder -wing aircraft from the 1920s. The model, built by the Berliner Albatros Flugzeugwerke , offered space for one pilot and five to six passengers.
history
At the beginning of the 1920s, the Commission Aéronautique Inter-Alliée allowed civil aircraft construction in Germany again. The Deutsche Luftreederei then commissioned the Albatroswerke to develop a light passenger aircraft, which resulted in the L 58. The design of the L 58 was based on the unrealized L 57 design. The first flight of the prototype took place in 1923. Later the improved version L 58 a was created. This six-passenger model was powered by a Rolls-Royce Eagle VIII engine. The nine machines built initially came into the possession of Deutsche Aero Lloyd , the successor to Deutsche Luftreederei. The resulting Luft Hansa took over part of the aircraft in 1926 in order to use them for a short time. The last copy, the D-576 Wolkensegler , crashed on June 5, 1928 near Essen . Two aircraft were sold to the Soviet Union .
In 1926 Albatros developed an enlarged version designed as a biplane , the L 73 .
construction
The L 58 was a largely wooden, cantilevered shoulder-decker with a closed cabin (2.80 × 1.15 × 1.60 m) for five to six passengers. As drive a used Maybach - Mb-IVa -Motor. The pilot was in an open cockpit in front of the wings. The machine had a rigid grinding wheel chassis .
