WebAug 2, 2024 · Next we discuss the supersonic intake efficiency, which is defined as the ratio of the exit total pressure to the free stream total pressure. Figure 4 shows the supersonic intake efficiency variation along the engine intake. Reason for discrepancy between analytical and numerical solution is location of the normal shock formation. WebThe intake is provided with a variable geometry mechanism such that the throat is wide open at low subsonic speeds and closes progressively towards the supersonic regime. The mismatch between intake and compressor is avoided during the supersonic regime by deviating through the bypass duct and the variable geometry bypass nozzle (BN), the ...

WebMar 19, 2024 · A diverterless supersonic intake consists of a three-dimensional bump and a forward swept cowl lip. The bump serves the dual purpose of external compression as well as diversion of low energy boundary layer developed on the fuselage. The boundary layer is diverted by the combined action of bump and forward swept cowl. The cone angle is chosen such that, at the design condition for the inlet (Mach 1.7 for the English Electric Lightning inlet ), the shock wave that forms on its apex coincides with the cowl lip. The inlet passes its maximum airflow and achieves its maximum pressure recovery. A higher design speed may require two oblique shocks focussed on the lip to maintain an acceptable pressure recovery and pass maximum airflow. In this case a biconic cone is required with two angles ( the Bristol … dora cvitkušić
