In Russia, a technology demonstrator for a supersonic civilian aircraft is being created, reported the Zhukovsky Central Aerohydrodynamic Institute (TsAGI). This novel flying vehicle, whose development is underway in collaboration with UAC, UEC-Klimov, and the Central Institute of Aviation Motors, has tested an innovative upper engine placement. Such a configuration lessens the sonic boom level during supersonic flight.
In the initial phase, specialists analyzed and produced models of the power unit’s components: two engines complete with air intake devices and flat jet nozzles featuring an oblique cut. This nozzle design is being utilized in Russia for the first time. Tests conducted in wind tunnels demonstrated that the air intakes provide performance superior to standard ones, while thrust losses from the flat nozzles remain within acceptable limits.
The RD-93MS engine, adapted for the demonstrator, was tested on a ground stand at JSC “UEC-Klimov” utilizing TsAGI’s noise reduction system. Thrust performance confirmed adherence to the technical specifications. TsAGI General Director Kirill Sypalo emphasized the strategic importance of supersonic civil aviation for Russia and noted the project’s technological viability.
