Tupolev TU-134B

One of the latest modifications of the aircraft was the Tu-134B. Improving the design of several units and systems allowed to increase profit per flight hour and reduce specific fuel consumption. At the first stage, it was supposed to create a Tu-134B for 80 passenger seats, and at the second – to develop an option for 90-92 passengers. At the same time, the empty curb weight of the aircraft was reduced by 1000-2000 kg, fuel efficiency was increased to 39 g / pass.km. In the third stage, it was planned to increase the number of passengers to 100-110, replace the wing with a new one with a supercritical profile, and install engines with a noise suppression system. In this case, fuel efficiency when flying to a range of 2200 km could reach 25 g / pass, km.

Having increased the fuselage to 38, 445 m, it was possible to bring the number of passenger seats to 80, while the combination of the functions of a navigator and a co-pilot made it possible to reduce the crew to three people. In the vacant bow of the fuselage, the Groza-134 radar was installed instead of the ROZ-1. The prototype Tu-134B (USSR-65146) was built at KhAZ at the end of 1979. It successfully passed the tests and was put into serial production, becoming the first domestic main passenger aircraft with a crew of three without a navigator. Since March 1980, about 30 aircraft of this modification have been assembled at KhAZ. Based on the Tu-134B built Tu-134B-1, Tu-134B-3. The aircraft became the basis for the training Tu-134UB-L.


  • Tu-134B – the modernized Tu-134A. The empty weight was reduced, large rear emergency exits were added, the crew was reduced to 3 people, a new layout of the cabin, cargo compartment, and utility rooms was developed, passenger capacity increased to 80 seats. Serial production began in March 1980. Instead of the glazed navigational cabin of the navigator, the Thunder-134 radar system was installed. The control of the power plant, elevator trimmer, and navigation system is transferred to the central console. Unlike the Tu-134A with a radar nose, 2 locator screens were installed on the side panels instead of one in the middle. Some models of B have an increased fuel supply.
  • Tu-134B-3- modernized Tu-134B aircraft with Solovyov’s D-30 engines of the third series.
  • Tu-134BV-modification for the delivery of shuttles to a great height with their subsequent launch into space.
  • Tu-134B “Salon” – a luxury aircraft based on the Tu-134B. Notable for the presence of a second door for passengers in the rear. Made 7 aircraft. A few more aircraft were converted from passenger Tu-134B, while the second door was missing.
  • Tu-134M – a project of the modernized Tu-134B. The aircraft was supposed to install D-436T1-134 engines and new equipment. Designed in 1993.
