Tupolev Tu-144


Tu-144, which is the codification of NATO called Charger, - Soviet supersonic passenger jet Tupolev design.

Created in 60-years, he became the first supersonic airliner, which is exploited for commercial air transport airline.

History of the Tu-144

The first flight of the prototype Tu-144 31.12.1968 was performed. During the creation of the work carried out in two directions simultaneously. The first involves the creation nonafterburning economical turbojet RD-36-51, the second was aimed at improving the aerodynamic characteristics of the Tu-144.


As a result, we planned to receive a quest to achieve supersonic flight. In 1969, the Commission of the USSR the decision was adopted by a variant configuration of the aircraft powerplant with RD-36-51.

In parallel, the company MGA decision on the construction of six Tu-144 with more economical engines NK-144A. Upgrading to the new engines meet the requirements of the first phase of a supersonic flight range (4-4,5 thousand. Km), the serial model was planned to equip the engines RD-36-51.

The first pre-modernized Tu-144 1968 start putting in, at the MMZ "Experience." According to the calculations engines NK-144 could provide a range of supersonic level 3275 km flight, and NK-144A - 3500 km.

To improve the aerodynamic characteristics of the machine, it changes the shape of the wing. Was changed degree sweep on the leading edge of it was 76 °, and on the base - 57 °. Unlike «044», wing area was increased, tapered twist introduced intensive end of the wing. But most importantly, improved aerodynamics, - changes in the central part of the wing, which is provided in the self-balancing cruising speed modes. The changes affected the length of the fuselage, which could carry up to 150 passengers. Improved aerodynamic data processing contributed to form the bow of the fuselage. Twin engines with nacelles pushed, thereby freeing up space in the lower part of the fuselage. This arrangement resulted in a change in the chassis system: the main landing gear began to be placed under the engine nacelles, retracting held inside the channels between the air motors.

As a result of design improvements, increased fuel capacity and payload of the aircraft take-off weight increased to 190 tons (the project «044» the figure was 150 t).

The first pre-production copy of the Tu-144 was released at the beginning of 1971, and the first flight took place 1.06.1971. According to factory test program conducted flight 231, 55 flying hours performed in a supersonic mode.

20.09.1972 aircraft performed a flight on the route Moscow - Tashkent, which managed to overcome for hours 1 50 minutes. During the flight, the cruising speed of the car reaches 2500 km / h.

Series production aircraft Tu-144 was established at the Voronezh aircraft factory.


The production model, which was equipped with engines NK-144A, first raised in the air 20.03.1972. In contrast to the pre-production machines, a few added wing area, which resulted in an increase in the take-off weight of up to 195 t.

3.06.1973 first production aircraft crashed in front of 350 thousand. spectators. The crew wanted to repeat the feat of "Concord", which is performed before the "plains-destroyers" maneuver - to fly over the runway and take off again. However, it was not possible to do so. Since the height of 1200 m, the plane suddenly began to dive and only reaching 120 m above the ground, began to rise slowly. Overloading is much higher than the permissible level, whereby the first came off the left wing, and then - the rear compartment. The design of the aircraft completely destroyed. The crash happened near the small French city of Goussainville. As a result of the disaster killed all the ship crew and local residents 7, 28 people were injured.

The first passenger flight involving Tu-144 1.10.1977 held. Until May 1978 was carried out on the aircraft 55 47 passenger and cargo flights.


Total produced 17 copies supersonic airliner Tu-144, 14 of which - in Voronezh. passenger cabins equipment ordered in the GDR. At the present time, two of the Tu-144 stored in aviamuzeyah Monino and Ulyanovsk.

Design Tu-144

Tu-144 - is an all-metal nizkoplan, which was carried out on "tailless" scheme. The fuselage of the aircraft is made by the type of semi-monocoque and has a smooth stressed skin with stringers and frames set. Chassis Tu-144 tricycle present bow rack.


The structure of the power plant consists of four turbojet engines NK-144A, in the modification of the Tu-144D - besforsazhnyeRD-36-51A. Each of the motors has its air intake. Location of air intakes - paired. The nose landing gear is retracted into the space of the front part of the fuselage between the air intakes.

Wing Aircraft variable sweep. Covering of the wing is made of aluminum alloy sheets. At the trailing edge elevons placed titanium. They, along with rudders perform deviation due to irreversible boosters. The cabin is made by the mobile type "duck" to provide a better view during takeoff and landing.

Most of the fuel stored in the wing tanks 18. In the rear part of the fuselage placed a balancing tank. It enters the fuel transition from subsonic to supersonic speed mode. Performing landing can be carried out at any time and in any weather conditions. New technical solution is to debut in the history of the use of Soviet aircraft on this plane of automated health monitoring system on-board systems. This in turn has reduced the time and the complexity of the machine maintenance.

Interesting facts about Tu-144

Tu-144 used not only as liners. They are involved in research of solar eclipses, the ozone layer, a focused sonic boom. These aircraft became the Cosmonaut Training Center, who trained at "Buran" program. In 1983, the test pilot ST Agapov installed on Tu-144D thirteen world aviation records, which are not beaten until the present time.
