The ChAI-3 ( Russian ХАИ-3 ) with the nickname " Sergei Kirow " was a single-engine Soviet flying wing passenger aircraft and in this capacity the first of its kind in the world.
development
It was built in the mid-1930s by the “Aviawnito” design team from the Kharkov Aviation Institute (ChAI) under the direction of Alexander Lazarew .
The plane was made entirely of metal. The two separate cabins for six passengers each were located on both sides of the central axis and the engine was housed between them on the fuselage. The triangular vertical stabilizer was kept quite large to ensure the necessary stability of the machine.
On September 14, 1936, the ChAI-3 was completed and took off on its maiden flight, on which the machine was equipped with a double control and two pilots sat in the front of the cabins. On September 27, flight tests began, which also included a flight from Kharkov to Tambov . It turned out that the machine was difficult to control and, in particular, that it was difficult to coordinate turns.
Next, in 1937, a twin-engine development for eleven passengers under the designation ChAI-8 was tackled. However, since Aeroflot was not interested in this type of aircraft, the program was discontinued before the production of a prototype.
