The Tupolev Tu-75 ( Russian Туполев Ту-75 , NATO code name : "Cart" ) is a military transport aircraft developed by the Soviet design office Tupolev from the 1950s. It was developed from the Tupolev Tu-70 , which in turn was based on the Tupolew Tu-4 bomber, but had a newly developed fuselage and was specially developed for transport tasks.
description
The Tu-75 is a four - engine low -wing aircraft with nose wheel landing gear and conventional tail unit in all-metal construction. Compared to the original model, the airframe has been reinforced, a higher take-off weight has been approved and the fuel capacity has been increased by around 50 percent. The cabin had no pressure compensation, but a rear loading ramp with which smaller vehicles and bulky cargo could be taken on board. Only one machine was built.
In contrast to the Tu-70, the Tu-75 was only intended for military use from the start. About ten tons of cargo or up to 120 soldiers on folding seats could be taken on board. Like the Tu-4, the Tu-75 was to be equipped with defensive armament on the top and bottom of the fuselage and in the stern. This was also provided for in the prototype, but it was not installed. An autopilot, a car navigator with an automatic sextant , a LORAN receiver, a radio compass , an instrument landing system and a radar warning device were provided as avionics . In addition there was the usual radio equipment.
The first flight took place on January 21, 1950 by W. P. Marunow. The test phase went without incident. All tests were successfully completed by May 1950. In July of the following year, the aircraft took part in the Moscow-Tushino air parade . The primary task was to transport goods, drop paratroopers and transport the wounded. Series production did not materialize, however, as the production of the Tupolev Tu-85 and the jet-powered successor to the aging Tu-4 were on the production schedule for Tupolev . There were no free resources to put the machine into production.
The machine was used as a transport machine for a number of years and had to be written off and scrapped in 1954 after a crash near Kazan .
