The tenth flight of the SJ-100 prototype aircraft with PD-8 engines, developed by the United Engine Corporation (UEC), has already been completed in Komsomolsk-on-Amur. The press service of Rostec showed a detailed flight video of the aircraft.
During the flight, which lasted 3 hours and 20 minutes, the aircraft reached an altitude of 12,200 meters and a speed of Mach 0.81. The total operating time at this altitude was about two and a half hours.
At maximum altitude, the fuel efficiency of the cruise power plant was evaluated. At medium altitude, the engine's operability was checked at zero normal overload, and a zero-gravity mode was achieved in accordance with the test program.
According to the flight results, the PD-8 engines demonstrated stable operation in all tested modes. The power plant was tested as part of the aircraft for the first time at such altitudes, speeds, and overloads.
Earlier, www1.ru reported that a unique production of titanium pipes for aviation has been launched in Russia.
