Re: Izhorski Giant Biplane Heavy Bomber Project

Hi,


here is also the Izhorski giant biplane heavy bomber,they though that Biplane was
designed before the Triplane.

M.Maslov Russian aircraft 1914-1917

Planes Izhorskogo plant Izhorskij Shipyard, located in Kolpino near St. Petersburg, is the largest state-owned enterprise, carrying out orders of the Russian Navy. Since 1910 there existed aeronautic department, which has built three semi-rigid airship design: "Dove" (1910), "Falcon" (1911), "Albatross" (1913). In the period 1914 - 1916 years. here started making airship "Air cruiser," the construction of which for various reasons did not complete. At the same time Izhorskij attempts to build large bombers. In the period 1916 - 1917 years. Here drafted giant heavy bomber aircraft, made under the scheme biplane and triplane. Power plant - engines, "Reno" 220 hp or "Hispano-Suiza" 200 hp It is known that the biplane version was approved by the Technical Committee and in accordance with Uvoflota issuance of the order of 21 October 1916 was being built. Parts were manufactured and launched its assembly. Work stopped at 40% strength aircraft readiness May 25, 1918 The project triplane was considered in May 1917, a little later admitted reasonable to build a smaller model of the flying machine. As a result, the construction did not take place.

From this Russian book,

Izhorski Shipbuilding Plant, located in Kolpino near St. Petersburg
was the largest state an enterprise fulfilling the orders of the Russian navy. Since 1910, there was an aeronautical department here, which built three semi-rigid airships designs: "Dove" (1910) ، "Falcon" (1911) ، "Albatross" (1913). During the period 1914-16 here they began to manufacture the airship "air cruiser" ،, the construction of which, for various reasons, was not completed.

At the same time, at the Izhorski plant, attempts were made to build large
bomber aircraft. During the period 1916-17 here they developed projects for six-engine giant aircraft made according to the biplane and triplane scheme. Power plant - Renault engines 220 hp or "Hispano Suiza" 200 hp well known, then
the biplane version was approved by the Navy's Technical Committee and, according to the issuance of an order dated October 21, 1916, was built.
Parts were made and started assembly. Work stopped at 40% readiness of the aircraft on May 25, 1918.

The triplane project was considered in May 1917, a little later it was considered reasonable to build a reduced flying model of this machine. As a result, the construction did not take place.
