The PD-35 power unit differs from the PD-14 aircraft engine of the fifth generation in that it belongs to the 5+ generation [...], 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.
In December 2020 [...], the first flight of the Russian medium-haul narrow-body passenger aircraft MS-21-310 ("Mainline aircraft of the XXI century 310") with Russian PD-14 engines took place at the airfield of the Irkutsk Aviation Plant.
In March 2019, the general director of the All-Russian Institute of Aviation Materials (VIAM), academician of the Russian Academy of Sciences (RAS) Yevgeny Kablov said that the PD-14 turbofan engine designed for the MS-21 aircraft "was only relatively recently developed and created" and is "absolutely outstanding".
In October 2018, PD-14 received A type certificate signed by the head of the Federal Air Transport Agency, Alexander Neradko.
