A 1/5-subscale wind tunnel of the RJTF (freestream Mach numbers = 3.4, 5.4 and 6.7 at the nozzle exits, 100 mm x 100 mm) was constructed to supplement the engine tests. A special group was formed in the Ramjet Research Division to conduct these studies and to develop new techniques for evaluation of aerodynamic and combustion performances. In this report, details of the subscale wind tunnel and the studies are summarized. First, the design, calibration of the wind tunnels and transient loads during the wind tunnel start are summarized, then various supplementary studies, i.e., engine alignments, air capture ratios, oil flow on engine internal walls, drag and wall pressure measurements and simulation of engine unstart process are explained. Studies on the mixing process of fuel injected into engines and on the ramp-compression-type inlets for a subsonic combustion ramjet engine are also introduced. A series of combustor experiments using cold flow was conducted to investigate flow structure around the fuel injectors behind backward-facing steps in scramjet combustors. In the component experiments, optical measurements, such as Particle Image Velocimetry (PIV) and Pressure Sensitive Paint (PSP) methods were applied. Measurement techniques for the RJTF engine tests were also developed in these studies. Freezing criteria of chemical reactions in gas sampling probes, six-force balances and response times in low pressure measurements are reviewed. In the appendix, designs of the M3.4-, M5.4- and M6.7-two dimensional, square, and M8-conical nozzles, an air-driven ejector and a noise suppressor are summarized, as are construction of a new wind tunnel and the heat loss in storage air heaters. Finally, the know-how accumulated during RJTF operations is mentioned.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
