The N. E. Zhukovsky National Research Center (NRC) registered a patent for the aerodynamic configuration of a prospective supersonic passenger aircraft. The document was published in the FIPS database on January 30.
According to the patent materials, the aircraft will receive an elongated nose section, a swept V-shaped wing, and air intakes located above the wing. This configuration is aimed at creating a reduced sonic boom level during flight.
The design includes an air intake system with a wedge-shaped two-link deceleration body, teardrop-shaped inlets, and engine-compartment purge ducts.
The project also provides for the use of flat jet nozzles placed in a recess between the fins. Additionally, an air-blowing system from the engine compartment is used during takeoff modes.
The aircraft is proposed to be equipped with a forward horizontal tail and an enlarged all-moving stabilizer. These elements were incorporated into the aircraft's overall aerodynamic design.
Calculations show that the overpressure of the sonic wave at an altitude of 15 km will be no more than 34 pascals, which on the ground will be perceived as a dull clap with a loudness of about 95 decibels, comparable to the noise of a metro train.
