Russian engineers from Central Institute of Aerohydrodynamics performed a supersonic cruise research for supersonic passenger aircrafts, flying over densely populated lands.
      
      For this purpose they cooperated with “Sukhoi New Civil Technologies” company and Central Institute of Aviation Motors. Joint think-tank developed preliminary aerodynamic configurations for commercial supersonic aircrafts with cabins of various comfort levels and seats for 4-50 passengers.
      
      Engineers also elaborated recommendations for appearance of mentioned advanced aircrafts and estimated aerodynamic, general, performance and ecological characteristics: airport noise and sonic boom level during supersonic cruising. The research shows that there exists a possibility to make a sonic boom much lower than it is now, and fulfilling airport noise stabdards also isn’t a problem.
