After the success achieved with the prototype as the first supersonic airliner in the air, it was necessary to improve the design to correct some problems detected and to overcome the 3,500 km range in supersonic flight.
To optimize the aerodynamics of the aircraft in supersonic mode, the wing was deeply modified and its surface increased. The length of the fuselage was also increased to transport 150 passengers and the engines replaced by the improved NK-144A model.
One of the most important changes was the new configuration of the engines in two different and separate nozzles with two engines and their own air intakes each. This option solved the problems of vibrations and high temperatures in the lower part of the fuselage. A new and original retraction system of the main landing gear was developed because it was now located between the two engines.
Another important change was that two stabilizers (canards) were added to the front of the fuselage to provide stability on landing and takeoff. With all these changes the takeoff weight increased to 190 tons.
CCCP-77101 was the last aircraft produced at the MMZ “Opyt” plant and assembled in Zhukovsky, and the first of the Tu-144S model. In April 1973 it was used as the setting for a press conference.
