ANT-17 Heavy attack aircraft

In the late 20s, the process of active mechanization of the armed forces was going on in the world. Specialists of the domestic Air Force began to pay attention to the creation of assault aircraft, sufficiently effective to combat the motorized parts of a potential enemy.

The STC of the Air Force under the leadership of SV Ilyushin developed TTT for armored attack aircraft. In 1929, the task to develop such a machine was issued by the AN Tupolev Design Bureau. The document provided for the creation of a heavy armored attack aircraft (TSH-B), capable of destroying tanks and armored vehicles.

During 1930, the design team of Tupolev prepared a draft of the aircraft, equipped with a powerful 75-mm dynamo-jet gun, 8 machine guns of 7.62 mm caliber and a bomb load of up to 1500 kilograms. TSH-B received a rational booking system that protected the vital parts of the aircraft: crew jobs and powerplant.

The total mass of armor reached 1000 kilograms, of which 380 kilograms were part of the power circuit design. Armor protected all the vital parts of the aircraft, jobs pilot, navigator, scorer, two shooters, as well as engines and gasoline tanks. The total mass of armor on the plane reached 1000 kg, but only 380 kg of them were included in the power circuit design, i.e. perceived various loads acting on the aircraft. In parallel, the development of several variants of the layout of the aircraft with different load variants and reservations for M-34 750 liters engines with (4 options), Isotta-Fraschim "ASSO" 800 l was carried out. from. (3 options), BMW-6 730 l. from. (3 options) and BMW-9 800 liters with (2 options). The best option turned out to be motors "ASSO".

In the course of further design, it turned out that it was not possible to obtain the required performance due to the large mass of "idle" armor. The design team decided to postpone work on heavy attack aircraft. In the USSR, the idea of creating armored vehicles came back in the second half of the 1930s, when the necessary brands of aviation armor and its processing technology appeared, which allowed the Ilyushin Design Bureau to create the legendary attack aircraft of the Great Patriotic War Il-2 in a short time.

The ANT-17 was one of the latest projects of the biplane aircraft developed by the AN Tupolev Design Bureau - all subsequent machines were created according to a monoplane scheme.

ANT-17 [second] (TSh-1 / TSh-B)

Along with the original version of the biplane, another version of the ANT-17 was developed, a monoplane, but not the original design, but based on the TB-1 aircraft. Works on the TSH-B attack aircraft were carried out in the order of modification of the serial TB-1 bomber. The TSH-B was a twin-engine four-seater with a non-retractable landing gear, powerful gun and armament and strong armor protection.

Armor (thickness 3.54.5 mm) protected all vital parts of the workplace for the pilot, navigator, scorer, two shooters, as well as motors and fuel tanks. The total mass of armor was about 1000 kg, of which only 380 kg were part of the power scheme of the aircraft design.

In parallel, the development of several variants of the layout of the aircraft with different load variants and reservations for M-34 750 liters engines with (4 options), Isotta-Fraschim "ASSO" 800 l was carried out. from. (3 options), BMW-6 730 l. from. (3 options) and BMW-9 800 liters with (2 options). The best option turned out to be motors "ASSO". In order to facilitate the machine, experiments were carried out on the use of armor-reinforced plywood in the design of the aircraft. Various options of small-gun and bomb weapons were also considered.

on June 21, 1931, at the extended meeting of the Air Forces and TsAGI Scientific and Technical Complex, A.N. Tupolev reported that the technical data of the TSH-B specified by the STC could not be implemented due to the large mass of inoperative mounted armor and the absence of 1,300-liter motors.

As an alternative, A.N. Tupolev proposed adapting the R-6 twin-engine reconnaissance aircraft to act as an attack aircraft. The military agreed with the proposal of A.N. Tupolev by setting the deadline for presenting a new car (factory designation ANT-18) to state tests by January 1, 1932. Later, due to the lack of necessary power engines, the construction of an attack aircraft based on P-6 was also discontinued.
