The National Aerospace Laboratory of Japan constructed a ramjet engine test facility (RJTF) at the Kakuda Research Center in 1994. It can duplicate engine test conditions in the range of flight Mach numbers from 4 to 8. The facility can supply non-vitiated air for M4 and M6 to identify the contamination effect in the vitiated air, to provide the basis for evaluating engine performance in the M8 flight condition. This paper outlines the unique features and operating characteristics of the RJTF. The quality of air stream obtained during facility calibration, and the facility-engine interaction are described. Finally we review tests oa an H2-fueled scramjet that are currently underway.
