Russia is three years ahead of the United States in developing an engine for supersonic civil aviation. This was stated by Andrey Kozlov, General Director of the Central Institute of Aviation Motor Engineering named after P. I. Baranov.
According to him, Russia is currently the sole leader in this area.
They [the USA] are about three years behind. The Americans scattered the project to startups, but could not put the individual "cubes" together. Because it is, indeed, a very complex, very high-tech thing.
Kozlov clarified that the task is to ensure that the aircraft carries the maximum payload. To do this, it is necessary to lighten the engine as much as possible. Certain developments are already in place, for example, composite blades are significantly lighter than titanium ones.
We have formed a list of critical technologies that are needed to create the engine. This includes new materials. But the institute needs to conduct qualification tests not just of a new material, but of each specific part that will experience the strongest loads.
Prior to this, Baranov explained why the PD-8 and PD-14 engines are not suitable for a promising supersonic aircraft.
