To realize the goal of space transportation, that is a single-stage-to-orbit vehicle, not only technologies to operate the space transportation system frequently but also ones to innovate spaceflight performance are needed. Utilization of air-breathing engines in space transportation could innovate main propulsion systems of the space transportation system. We consider making a suborbital sounding rocket reusable with using the air-breathing engine, which results in realizing reusable sounding rocket in more compact scale. Furthermore, the realization of the reusable sounding rockets can also demonstrate the effectiveness of the air-breathing engines in space transportation. In this paper, system sizing and flight trajectory analysis of the reusable sounding rocket with the air breathing engines were conducted. From the analysis of the results, a relationship between the vehicle size and the flight performance was found. And also, the amount of propellant required for landing after deceleration by aerodynamic force was determined.
