Mach 6 Testing of a Scramjet Engine Model.

摘要

Testing of a sub-scale scramjet research engine model was carried out in the Mach 6 Ramjet Engine Test Facility of the National Aerospace Laboratory, Kakuda Research Center. With attachment of a short strut on the top wall, intensive combustion with high combustion efficiency was attained, and the engine-produced thrust canceled the drag. The flame was held in the low-velocity region around the step, even after the ignitors had been turned off. When the fuel flow rate was small, there was a different combustion mode with weak combustion and little thrust. Tangential injection of fuel inhibited intensive combustion.
