The aerospace system is based on the principle of rocket launch into low orbit. This
three-stage system consists of the subsonic carrier aircraft, hypersonic booster aircraft
and aerospace plane. To improve the aerodynamic efficiency and flight performance of
the aerospace system the booster aircraft design parameters have been optimized for
three types of fuel (hydrogen, methane and kerosene jet fuel). We have calculated the
streamlining of the assembled aerospace system and its stages. The air flow motion was
simulated by the solution of the Navier—Stokes equation using the turbulent model Ment-
er SST k–ω. We have carried out the comparison with the available data to validate the
numerical procedures.
