Abstract
This paper shows details of the aerothermodynamic conception and the mechanical design of an academic scramjet for flying with speed corresponding to a Mach number of 4.18 and altitude of 6.2 km, which consists in a sym- metrical oblique convergent inward-turning inlet ramps followed by the isolator, the combustor and the expansion section engine to operate in high supersonic regime. The Foguete de Treinamento FTI will accelerate the academic scramjet to the flight conditions. The methodology to design the scramjet geometry and calculate the aerothermodynamic proprieties of the airflow along it was the oblique shock wave theory (for the compression section), Rayleigh flow (for the combustion section) and Prandtl-Meyer flow coupled with area ratio relations (for the expansion section). For the mechanical design a CAD software will be used. The possibility of using airbreathing propulsion system based on supersonic combustion to replace the current propulsion systems within the next decades for cheaper, safer and more sustainable access to space has been the main motivation for this research.
