The Fieseler Fi 256 was a civil multi-purpose aircraft produced by the Gerhard Fieseler works .
history
The aircraft was developed on the basis of the Fieseler Fi 156 . The aircraft was similar in structure to the Fi 156, but was structurally simplified and slightly enlarged so that five people (a pilot in front and four passengers behind) could be accommodated. The draft was presented to the Reich Aviation Ministry on September 25, 1940, and series production was planned from spring 1941. The first flight of the Fi 256 V1 with Willy A. Fiedler at the controls took place on July 9, 1941 in Kassel-Waldau , whereby problems with the rudder emerged as part of further testing, which made a modification necessary. In addition, the shape of the elevators was changed to trapezoidal and moved a little downwards. The second prototype V2 had its maiden flight in autumn 1941, the V3 to V6 followed from spring 1942. In addition to the six test models produced, five more of the twenty machines planned as pre-series were probably manufactured by Otto Schwade in Erfurt between December 1942 and the end of 1943 . The actual series production never came about as other types of aircraft were given a higher priority.
The machines produced were used as personal transport machines (for example by Gerhard Fieseler ). Today there is no longer a copy.
construction
The focus of the development was on doubling the range to 700 km and increasing the maximum flight speed from 175 to 215 km / h, whereby the remaining parameters (such as good slow flight characteristics and the engine) should be retained. Above all, the aerodynamics have been improved. The cabin windows were installed flush with the fuselage instead of protruding, and the wings received automatically extending slats. The modified landing gear with lower air resistance, which was attached directly to the fuselage in a self-supporting manner, was tested on a Fi 156 (registration number: D-IGQE). Hardly any wood was used for the structure. The cladding of the two-spar wings and a large part of the tubular steel fuselage frame consisted of aluminum sheets. A fabric covering was only used for the oars and flaps.
