Analyzing of Internal Waverider Inlet and Sidewall Compression Inlet Performance

摘要：

A new internal waverider inlet which has regular rectangular shape of entrance and exit is designed at M=6.0. Its based on ICFC basic flowfield and derived with the technology of stream tracing and shock cutting. Comparisons are made between the newly designed inlet and a typical sidewall compression inlet. The design Mach number and entrance shape of this new inlet are chosen according to the sidewall compression inlet. Numerical results show that most of the performance parameters of the internal waverider inlet are a bit higher than the sidewall inlet, such as the flow capture coefficient, total pressure recovery and the kinetic efficiency. The paper compares the performance of these two inlets at off-design points as well, the internal waverider inlet can capture more than 91％ of incoming flow at all conditions simulated, and shows a better performance either. This paper proves that internal waverider inlet using special technologies which lead to three dimensional compression as well as high flow capture coefficient is a kind of fixed-geometry inlet with great performance.
