At hypersonic regime, it will be operated at rather high rocket engine output forfinal acceleration with some Isp gains due to air-breathing effects. In this regime, attaining thrust at this high-speedregime becomes very difficult, so that parallel injection of the fuel for scramjet combustion is favorable as the momentumof the injection can contribute to the thrust production. Thus, embedded rocket chamber was supposed to the operated asfuel rich gas generator at very high output. This configuration was tested at simulated flight Mach number of 11 at HighEnthalpy Shock Tunnel (HIEST) with detonation tube as the source of the simulated rocket exhaust. However,combustion of the residual fuel in the rocket exhaust with airflow could not be attained in the past study, so thatmodification was carried out. Combustion was attained within the combustor, however, insufficient mixing was found toresponsible for the rather low combustion efficiency, finding being from complementary mixing test at a blow-down typetunnel., 資料番号: PA1410085000}, pages = {Pa_71--Pa_77}, title = {Combustion Phenomena within a RBCC Engine under Scramjet-mode Operation}, volume = {12}, year = {2014} }
