Therefore scramjet engines must be tested under conditions of boundary layer ingestion in ground testing. The ingestion promotes engine stall (or engine unstart) in combustion tests. In order to prevent boundary layer separation in the inlets and extend the engine operating range, boundary layer bleeding was examined in Mach 4 and Mach 6 engines in the RJTF. Bleeding of air inflow in the engine of about three percent extended the operation range of the equivalence ratio from 0.3 to 0.8 and doubled the net thrust. Details of designs of the bleeding device and the bleed air cooler are described and the characteristics observed in the engine tests are reviewed. Improvements in engine performance and the design of the Mach 6 bleeding device are discussed.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
