Abstract: The mass flow capture performance is a key characteristic of the integrated Curved Cone Waverider forebody Inlet(CCWI). Delicate mass flow measurement experiment and comparison studies between experiment and simulation are conducted for obtaining the CCWI's mass flow capture ratio. Using the mass flow measurement experimental system, the CCWI's mass flow capture and static pressure distribution are obtained at free stream flow Mach number(Ma_∞)3.0, 3.5 and 4.0, Angle of Attack (AOA) from -4° to 6°。Comparison studies of CFD simulation and experiment are carried out at Ma_∞=4.0, AOA from -4° to 6°。Based on the verified CFD software and simulation methods, the mass flux and compression performance of the CCWI are examined at Ma_∞=4.0 and 6.0. The results show that the average square error of the mass flux measurement is less than 2%. Simulation and experimental results agree well with each other. The CCWI has good flow compression abilities and its mass capture ratios are 0.60, 0.68 and 1.00 at Ma_∞=3.5, 4.0 and 6.0, AOA=0° respectively.
