The gas generators of the new Russian aircraft engines PD-8 and PD-14 are not suitable for creating a power plant based on them for a new promising supersonic aircraft. This was stated by Andrey Kozlov, General Director of the Central Institute of Aviation Motor Engineering named after P. I. Baranov (CIAM).
Kozlov recalled that the heart of any engine is a gas generator.
PD-14 and PD-8 gas generators were considered. The results of the research showed that creating a power plant for a supersonic aircraft based on them is impractical. The reason? Due to the need for significant modifications: meeting the requirements for efficiency, environmental friendliness, reliability and service life is comparable to the development of a new engine.
Kozlov added that the engine of any aircraft is designed for how exactly this aircraft will fly. Depending on these tasks, the necessary blade profile, disks and corresponding alloys are already selected.
Technically, you can take a universal gas generator and design different engine families based on it. But this is not about supersonic. This is a separate story that is fundamentally different.
Andrey Dutov, General Director of the National Research Center "Zhukovsky Institute", told "Perviy Technicheskiy" that airlines are considering options with a wide-body aircraft, for which the PD-26 engine will be built.
