TsAGI "Zhukovsky Institute" has received a new patent for the design of a promising supersonic passenger aircraft. The liner will be able to fly with reduced sonic boom loudness and lower noise levels near airports.
Engineers have solved a key problem — combining high flight speed with acoustic and economic requirements. This should make supersonic transportation more suitable for mass use.
The technical result of the invention is the development of an aerodynamic configuration of a supersonic passenger aircraft that provides flight in a cruising supersonic mode with a Mach number of 1.7, with a sonic boom loudness level of approximately 95 PLdB.
The developers have incorporated solutions to reduce noise during takeoff and landing, including features of the nozzle design and engine placement. The project includes a swept wing, over-wing air intakes, and a twin-engine power plant.
The institute recalled that previous generation aircraft, such as the Tu-144 and Concorde, do not meet modern noise requirements, which limits their use.
The creation of a new supersonic passenger aircraft remains an urgent task due to the need to increase the speed of transport communication.
Kirill Sypalo, General Director of TsAGI, previously stated that the new supersonic aircraft "Strizh" can be implemented by 2028. According to him, many new technologies are being introduced into the project, including aerodynamic configurations and the basics of a "dark cabin."
Andrey Dutov, General Director of TsAGI "N. E. Zhukovsky Institute," noted that the future Russian supersonic aircraft will fly without a retractable nose cone, as was the case with the Tu-144.
