The NIAI LK-1 or NIAI-1 Fanera-2 ( Russian: НИАИ ЛК-1 Фанера-2 ) was a Soviet airliner . Designed and built, it was the scientific Aviation Institute ( N autschno- I ssledowatelski A ERO I nstitut ) Leningrad Alexei Ivanovich Lissitschkin and Vladimir Fedorovich Rentel.

development

The special thing about this wooden type (Fanera means plywood ) was the accommodation of the pilot and passengers in two cabins located on the wing on the right and left of the fuselage. The pilot was sitting to the left of the engine and had a very limited view to the right.

Since the model only a low-power M-11 - radial engine should receive, the designers were forced to keep the weight as low as possible. The hull was given a broad and flat shape and thus contributed to the buoyancy .

The flight tests were carried out by A. I. Ivanov in May 1933 in Leningrad and later in Moscow. It was decided to build 20 aircraft, the construction of which was taken over by the Leningrad repair plant. In contrast to the prototype, these had a modified vertical tail, streamlined main landing gear fairings and a townend ring around the engine . The LK-1 was used by Aeroflot mainly on its Arctic routes and in the Far East . An LK-1 was used in the 1936 film "The Seven Bold" by Sergei Gerasimow .

There was also a float version called the NIAI-1P .
