The LK-1 a.k.a. Fanera-2 (Plywood no.2) or NIAI-1 was a four-seat cabin aircraft designed and built in the USSR from 1933.
AI Lisichkin and VF Rentel of the NIAI (Aviation Scientific Research Institute, Leningrad) designed the LK-1 in an attempt to build a very efficient small transport aircraft with the wing blending into the fuselage, forming the cockpit and cabin, with seats for three passengers and one pilot with extensive glazing. Construction was all of wood/plywood, with a conventional single spar wing with plywood covering.
The engine, with Townend ring cowling, was fitted on the centre-line between the font cockpits which gave the pilot an asymmetrical view through the leading edge glazing. The fixed tricycle undercarriage was fitted with spats to reduce drag.
Flight trials at Leningrad and state tests at the NII GVF(Scientific Research Institute for Civil Air Fleet), in Moscow, were very successful and an order for twenty production aircraft with modified tails, spats removed, no Townend ring, and other modifications was placed, for use by Aeroflot inside the USSR and the Arctic.
