ANT-26 (TB-6) Heavy bomber (project)

At the end of 1929 STC UVVS suggested that the KB give an opinion on the possibility of constructing airplanes with a carrying capacity of 10 and 25 tons capable of carrying guns and tanks and communicating their basic parameters. Preliminary data on 2 cars were worked out in the design bureau under the given variants of load-carrying capacity. The first option became the basis for the design of the ANT-16 (TB-4) aircraft, the second - for the project on the "super bomber" ANT-26 (official designation TB-6).

The estimated term for the construction of such a machine KB was determined in 3-4 years. Soon, the Air Force takes a principled decision on the construction of the ANT-26. Beginning in 1931, the AN-26 (TB-6) aircraft starts to appear in the plans of the Design Bureau and the Air Force for experimental construction. The design bureau and civil aviation showed interest in the new development. Two variants of the aircraft were included in the plan: passenger and cargo for a commercial load of 15 tons and with a range of 1,500 kilometers. Civil projects went to the design bureau under the designation ANT-28.

In March 1932, the KB began to implement these projects. A.N. Tupolev immediately raised the question of the construction of a plant for the serial construction of ANT-26 and a plant for their repair, the dimensions of which were to satisfy the dimensions of these giants. The design work was carried out by Aviaproject and became the basis for the construction of two aviation enterprises of the country: Plant No. 124 in Kazan and No. 84 in Moscow. The layout and design of the ANT-26 aircraft was the further development of the ANT-16 (TB-4) in the direction of increasing the overall dimensions, mass and power of the power plant. The project provided for the use of 12 M-34 engines on the plane, 8 of which were installed in the wing and 4 in two tandem installations above the wing. In the future, in connection with the additional requirements of the military to expand the composition of defensive weapons.

In 1935, a two-seater towing model-glider was built in the scale of 1/4 of the full-scale ANT-26 to study questions related to aerodynamics of the aircraft. Her flight tests with the removal of characteristics carried out test pilot BN Kudrin. Having slowed down all work on civil modification, the design bureau completely focused on the military option. In pilot production, the construction of the aircraft began. The aircraft continues to figure in the plans of the Air Force for experimental construction in 1933-1934 (the machine is referred to as TB-6-6M44) with the completion of construction by December 1935, and then - by August 1, 1936.

In July 1934, all work stopped on the project at a total airframe technical readiness of 75% and the entire aircraft - 16%.

The ANT-26 project ended the era of prewar design in the design bureau of giant slow-moving "bomb-carriers". The future was for high-speed high-altitude machines capable of performing combat missions in conditions of increased air defense power.

ANT-28 (TB-6)

Two versions of the heavy bomber ANT-26 (TB-6) were designed in the design bureau, intended for operation in the Civil Air Fleet. The payload for the passenger and cargo variants was determined to be 15,000 kg, and the range was 1,500 km. Works were terminated at the initial design stage.
