  • A 2-Dinternal flow field of hypersonic inlets was simulated numerically at different suction rates.The effects of the backpressure on the internal flow field of the isolator were analyzed.The influences of the boundary layer suction on the maximum backpressure were also discussed,showing the variation of the maximum backpressure with the suction rates.The reasons why the maximum backpressure of the hypersonic inlet is improved by the suction technology were analyzed.The results show that,the boundary layer suctions can improve the maximum backpressure of the inlet,which increases the length of the isolator to some extent.The more the suction of airflow is,the stronger backpressure of the inlet will be.
