Abstract
The involvement of several research centers around the world with studies on the application of ramjet airbrething propulsion jet engine with supersonic combustion is due to its ability to make space access more economical. The 14-X Hypersonic Vehicle is a strategic project of the Brazilian Air Force and is being developed at the Prof. Henry T. Nagamatsu Laboratory located at the Institute of Advanced Studies (IEAv), this vehicle aims to demonstrate the scramjet and waverider technology in flight with an altitude of 30 km and a speed corresponding to Mach 10 number. This scientific article aims to document the experimental study of supersonic combustion performed in the Hypersonic Shock Tunnel T3, at Nagamatsu Laboratory, of an academic scramjet model. The academic model used in this work is approximately 1,200 millimeters long and was instrumented with 24 pressure transducers along the geometry. This work aims to compare tests without injection of fuel with injection of hydrogen as fuel to verify differences in the profile pressure obtained by the transducers pressure installed in the combustion chamber and after the combustion chamber.
