The Heinkel HD 42 (later Heinkel He 42 ) was a seaplane that was initially built for the German Aviation School (DVS) and was then used by the German Air Force to train sea pilots well into the Second World War .
development
As early as 1929, Heinkel , at that time still camouflaged, developed the sea double-decker HD 42 for the German Aviation School . The initial model for this was the HD 24 from the 1920s, which gained a good reputation in service with the Swedish Navy and with which Gunther Plüschow carried out his famous flights over Tierra del Fuego . The prototype HD 42a (Wnr. 333) still had a BMW Va engine and was tested at DVS Warnemünde in early 1930. Initial stability problems have been eliminated by making changes to the surfaces and the fuselage. The aircraft was registered for the DVS in February 1930 with the registration D-1793. In the same year the school ordered four more aircraft (Wnr. 372 to 375), which were delivered and certified as H D 42b , now with Junkers L 5-G engines , in April 1931. Changes were also necessary to them, after which the aircraft was then judged to be well suited for its task.
production
Another five aircraft were built for DVS in 1932 and approved in October with the new uniform designation He 42 C. It was the Wnr. 419 to 422 and 428. Series production began in 1933 with 14 He 42 D (Wnr. 443 to 456), which have now been taken over by the Luftwaffe , which is under construction under the code D-2543 to D-2556 . From 1934 189 He 42 E aircraft followed , which were distributed to the various schools and flew until the end of the Second World War.
description
The Heinkel He 42 was a two-seater two-swimmer biplane, the hull of which consisted of a welded tubular steel frame with a rectangular cross-section and a rounded top. While the engine area was clad with easily removable light metal sheets, the rest was covered with fabric. The wings, each connected to one another with an N-shaped handle, did not require any bracing thanks to the stiffening float structure. The upper and lower ailerons were connected by bumpers. The tail unit consisted of a tubular steel frame and, like the wings, was covered with fabric. The heavily keeled wooden floats had one step and were divided into six compartments each sealed from one another by bulkheads. 350 l of the fuel supply were in a fuselage container behind the firewall and a further 75 liters in a container in the upper wing.
