The new Russian aircraft engines PD-8 and PD-14 are not suitable for a prospective supersonic aircraft. This was stated by Andrey Kozlov, General Director of the Central Institute of Aviation Motor Engineering named after P. I. Baranov (CIAM).
According to him, the designers went through all the options that can be applied. Kozlov recalled that the heart of any engine is a gas generator.
We considered gas generators PD-14 and PD-8. The results of studies have shown that creating a power plant for a supersonic aircraft on their basis is impractical. Due to the need for significant refinement, meeting the requirements for efficiency, environmental friendliness, reliability and service life is commensurate with 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 selected.
Technically, you can take a universal gas generator and on its basis design different engine families. But this is not about supersonic. Here is a separate story that differs dramatically.
Andrey Dutov, General Director of the National Research Center "Zhukovsky Institute", told "First Technical" that airlines are considering options with a wide-body aircraft, for which the PD-26 engine will be built.
