The Saveliev four-decker ( Russian Четырехплан Савельева , Tschetyrechplan Savelieva) was the prototype of a Russian military aircraft .
development
Together with Wladislaw Zalewski, Wladimir Saweljew built a two-seater reconnaissance aircraft in 1916 in the design as a four-decker , through which he aimed for high maneuverability. The fuselage was taken over from a Morane G , but the single-stem wing box was completely redesigned. On April 15, 1916, the prototype, equipped with an 80 HP engine, was flown in. The flight characteristics were rated as good overall, but the model turned out to be underpowered in this configuration. So they later built in a 100 hp monosoupape and made even smaller changes, which was followed by further intensive testing. In the end, however, the design did not go into production. But Saweljew tried again later on a four-decker construction, which in 1923 led to another prototype with smaller dimensions and equipped with a 125-hp engine from Gnome-Rhône. It reached a top speed of 164 km, but also remained a one-off.
