SUMMARY:

This monograph presents a conceptual study, under development at the Universidade Federal do Rio Grande do Norte (UFRN), of a supersonic combustion demonstrator (scramjet technology), during atmospheric flight, in constant hypersonic velocity of 1950 m/s in the altitudes of 21 km, 26 km and 31 km. The analytical theories of the oblique shock wave, the heat addition in one-dimensional flow in the cross section with constant area and the area ratio were applied in the compression, combustion chamber and expansion, respectively, considering air as a perfect gas and without considering viscous effects. The compression section angles were determined by ensuring that the temperature (higher than the fuel ignition temperature) and the supersonic velocity of the atmospheric airflow provided the stoichiometric burning of atmospheric air and hydrogen fuel in the combustion chamber. Also, it was considered that the incident shock waves have the same intensity providing on-lip and on-corner shock conditions. The expansion section has been optimized considering the combustion products have the same pressure at the scramjet flight altitude. Finally, it was observed the combustion products, in the expansion section, were at a hypersonic velocity greater than the flight velocity of 1950 m/s, allowing the generation the not installed thrust.
