"Лебедь-Морской-1" (ЛМ-1) с двигателем "Санбим" в 150 л. с. вместо первоначально предполагавшегося "Рено" в 220 л. с. был выпущен заводом Лебедева весной 1916 г. Схема - трехстоечный биплан на трех поплавках. Главные поплавки были установлены с амортизаторами в задних узлах крепления, третий поплавок - под хвостом.

H.Nowarra, G.Duval Russian Civil and Military Aircraft 1884-1969

A floatplane version of the Lebed XI was built, designated LM I (Lebed-Morskoi - Lebed-Naval) and originally fitted with the Sunbeam engine but re-engined with a Salmson. In appearance it resembled the Albatros WDD or W.I when powered by the Sunbeam, but the installation of the Salmson radically altered its profile.

Lebed-Morskoi LM-1

  In the spring of 1916 the LM-1 (Lebed Naval type 1) was completed. It was a three-bay Albatros floatplane copy, similar to the Albatros B.II except for use of a Sunbeam V-8 engine. By 1917 the Russian navy needed a two-seat tractor aircraft with a flexible gun for defending the rear. An order was placed on June 27, 1917, for 175 units. It was intended to power these with the 220hp Renault, but due to shortages of engines of more than 200hp this did not take place. Only two were produced at Taganrog by the end of hostilities, both powered by 200hp Hispano Suiza engines.


Additional Lebed Designs

  A few experimental models were produced, apparently without a series number designation. The reason for this is unknown, as well as the reason for a break in the numerical sequence. The following list is undoubtedly incomplete, but gives a good representation of types developed by Lebedev.
  It has been reported a small amount of Sunbeam-powered, three-bay Albatros two-seat aircraft were delivered to the army in late 1916. These were simply the LM-1 in landplane form and may have evolved from that project. The capacity in which they were employed is unknown, but the type was obsolete and presumably was used as a trainer.
  Supposedly, a pusher machine was designed in April, 1916. Other than it was intended to equip it with either a Salmson or a Renault engine, nothing is known of this aircraft.
  An experimental Albatros-type biplane with a 101hp Duflou and Constantinovich engine was built in 1916, but no other information is available on this machine.
  Another Albatros-style airplane was built in late 1916 with a 100hp Fiat engine installed. The top speed was only 59 mph and rate of climb was 25 minutes to an altitude of 3250 feet. Despite this very poor performance, three examples were produced and accepted.

В гидроаэроплане Лебедева "Альбатрос А. 2", иначе ЛМ-1, с заводским номером 217, также легко угадывается немецкое происхождение конструкции и опять-таки только V-образный "Санбим" 150 л. с. является чисто отечественным нововведением, да и то - импровизированным (89).
