Alexander Inozemtsev, Deputy General Director of JSC "UEC" for the management of the Perm Motors RPC, Managing Director - General Designer of JSC "UEC-Aviadvigatel", told on the sidelines of the International Military-Technical Forum "Army-2022" about the prospects for the production and modernization of the PD-14 engine, the required number of PS-90A, about the progress of development the PD-35 engine and about the possibilities opening up for designers after its appearance.
"We have just signed a loan with Novikombank for four billion rubles for the production of a very large batch of PD-14 for the next years," Alexander Inozemtsev told Alexey Samoletov, a journalist at Zvezda shopping mall, during a conversation.
He explained that the necessary production volumes of the PD-14 are currently so large that it is not planned to use this engine anywhere except for the MS-21 liner. "God forbid to swallow what will now be on MS-21-310. [...] The government has instructed us to reach 160 engines per year by the thirtieth year, this is with a reserve. There will be 72 aircraft [per year], plus a reserve," the deputy head of the UEC said.
Touching upon the line of promising engines and the modernization potential of the PD-14, Alexander Inozemtsev noted that so far this is the first member of the family. But there will be others with a thrust of 8 to 18 tons.
"Irkut Corporation is simultaneously making a smaller aircraft for an engine with a capacity of 12.5 tons instead of fourteen, and now they are actively engaged in the "four hundred" – MS-21-400. This is 16.5 tons and a larger capacity aircraft," A. Inozemtsev said.
MS-21-400 — the future flagship of Russian civil aviationRegarding the PD-8 engine, he said that the company "UEC-Saturn" is engaged in its development, and "UEC-Perm Motors" is an "accomplice" in this project, explaining that the required number of these engines is about 100 pieces per year.
"We need the Superjet to fly."
Answering the question about the continuity of the PD-8 and PD-14 gas generator, Alexander Inozemtsev stated that it was a mistake to consider the PD-8 gas generator as one of the PD-14 variants. "This is a completely new gas generator. It is smaller, more optimal for this small engine than the PD-14 gas generator and therefore a more technically risky project. The timing of its creation is very tight," he explained.
Alexander Inozemtsev also noted that in addition to PD-14 and PD-8, there will be a sharp increase in the production of PS-90A engines.
"Because the magnificent Tu-214 aircraft destroyed in the zero years ... "the head"made a decision: to make them urgently 70 aircraft before the 30th year. We are entering 120 PS-90A engines per year. This is together with military orders. This is also a huge volume. This is the engine that got into the most trouble... We received the type certificate on April 3, '92... And thank God that it is coming to life and will be made in the same quantities as the PD-14," said the general designer of JSC UEC–Aviadvigatel.

And depending on the engine, the undeservedly ruined Tu-214 machine also comes to life – a medium-haul liner capable of flying non-stop for 6-7 thousand km, for example from Moscow to Khabarovsk. Also, this liner is used for special purposes as a reconnaissance and surveillance aircraft. "The equipment has been saved, the technologies have been saved. Now we just need to remove the military cabin and put beautiful seats, and there will be a magnificent passenger plane," A. Inozemtsev said.
And the most important question that Alexey Aeroplanes asked the deputy director of the UEC: "What is the fate of the PD-35?".
According to Alexander Inozemtsev, in conditions of limited resources, unfortunately, the project will develop more slowly than previously planned. The PD-35 demonstrator engine will be assembled and tested by 2024.
"The PD-35 project will go a little slower, with a shift to the right for two or three years, because huge money is needed. Without a doubt, we will assemble and test a demonstrator engine by 2024, no matter how hard it is. And then we will go through the situation. But we will definitely understand, having assembled the engine, where we are in terms of technology, we are creating technologies for the long–haul aircraft market," A. Inozemtsev said. He added that the main forces will now be applied to the replication of PD-14 and PS-90A engines.
The General Designer of UEC-Aviadvigatel noted at the same time that the PD-35 has great potential. "This is the most innovative project. The latest technologies are absolute. This is a market niche of long-haul twin-engine aircraft, a colossal scientific and technical potential, which we must enter with the PD-35 and continue to make a family from 25 tons to 50 tons. This is what we are aiming for," Alexander Inozemtsev said.
He added that China is very interested in the PD-35 engine project. "It's going to get easier with the pandemic now, let's perk up."
