A. Inozemtsev - on the prospects for engines for aircraft from Tu-214 to MS-21-400
Alexander Inozemtsev, Deputy General Director of JSC UEC for the management of NPK Perm Motors, Managing Director - General Designer of JSC UEC-Aviadvigatel, spoke on the sidelines of the Army-2022 International Military-Technical Forum about the prospects for the production and modernization of the PD-14 engine , the required number of PS-90A, on the development of the PD-35 engine and on the opportunities that open up for designers after its appearance.
“We have just signed a four billion ruble loan with Novikombank for the production of a very large batch of PD-14s for the next years,” informed Alexander Inozemtsev to the journalist of the TV channel Zvezda Alexei Samoletov during a conversation.
He explained that the required production volumes of PD-14 are currently so large that this engine is not planned to be used anywhere except for the MS-21 liner. “God forbid to swallow what will now be on MS-21-310. [...] The government instructed us to reach 160 engines a year by the thirtieth year, this is with a reserve. There will be 72 aircraft [per year], plus a reserve,” said the deputy head of the UEC.
Regarding 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 is now actively engaged in the “four hundred” - MS-21-400 . This is 16.5 tons and an aircraft with a larger capacity,” said A. Inozemtsev.
Regarding the PD-8 engine, he said that the UEC-Saturn enterprise is developing it, and the UEC-Perm Motors is an "accomplice" in this project, explaining that the required number of these engines is about 100 units per year. "The Superjet needs to fly."
Answering a question about the succession of the PD-8 and PD-14 gas generators, Alexander Inozemtsev said 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 tough,” he explained.
Alexander Inozemtsev also noted that in addition to the PD-14 and PD-8, there will be a sharp increase in the production of PS-90A engines.
“Because the magnificent Tu-214 aircraft, ruined in the zero years ... the “leader” made a decision: to urgently make 70 aircraft before the 30th year. We start producing 120 PS-90A engines a year. This is along with military orders. This is also a huge volume. This is an engine that got into trouble... We received a type certificate on April 3, 1992... And thank God that it comes 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 car comes to life - a medium-haul airliner 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 preserved, the technologies have been preserved. Now you just need to remove the military cabin and put in beautiful seats, and there will be a magnificent passenger plane,” said A. Inozemtsev.
And the most important question that Alexey Samoletov asked the deputy general 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 gigantic money is needed. Without a doubt, we will assemble and test a demonstrator engine by 2024, no matter how hard it is. And then let's move on to the situation. But we will understand for sure, having assembled the engine, where we are in terms of technology, we are creating technologies for the long-haul aircraft market,” said A. Inozemtsev. He added that the main forces will now be applied to replicate the PD-14 and PS-90A engines.
At the same time, the General Designer of UEC-Aviadvigatel noted that the PD-35 has great potential. “This is the most innovative project. The latest technology is absolute. This is a market niche for long-haul twin-engine aircraft, a colossal scientific and technical potential, which we must enter with the help of the PD-35 and further develop the family from 25 tons to 50 tons. This is what we are aiming for,” said Alexander Inozemtsev.
He added that China is very interested in the PD-35 engine project. “Now it will be easier with the pandemic, we will revive.”
