, Alexander Inozemtsev, general designer of UEC-Aviadvigatel, told TASS.
"Compared to the PD-14 engine, the gas temperature in front of the turbine is increased by about 100 degrees Celsius, the compression ratio and the degree of double — circuit are increased by about 25 percent," the specialist said.
According to the general designer, within the framework of the PD-35 program, technologies are being developed that can well be attributed to the technologies of the sixth generation engines: high-temperature ceramic composite materials, intelligent self-propelled guns (automatic control system) and a diagnostic system, more electric motor technologies.
