In order to study the difference and mechanism of the internal flow total pressure loss between the boundary layer ingestion (BLI) inlet and the conventional S-shaped inlet, numerical simulation method was applied and step-by-step comparative analysis of the total pressure loss was carried out. The results showed that, when fan-face Mach number was kept unchanged, the flow loss of BLI inlet was larger than that of the conventional S-shaped inlet under the working conditions of relatively lower and higher Mach number of free-stream (corresponding to below 0.3 or above 0.6), and the maximum difference was 2.4 percent. Under the working condition of medium Mach number of free-stream (corresponding to between 0.3 and 0.6), the flow loss generated by the BLI inlet was slightly smaller than that of the conventional S-shaped inlet, and the maximum difference was 0.3 percent. The combined effect of the fore-wall of the BLI inlet and the low-energy boundary flow changed the flow characteristics in the inlet and developed rapidly in the diffuser of the S-shaped pipeline, leading to the difference in flow loss characteristics.
