AbstractTo realize the hypersonic transport or the low-cost fully reusable space transportation system, it is necessary to develop the SCRAM-jet engine. However, the performance of the SCRAM-jet engine is known to be quite sensitive to the air conditions at the inlet. In this research, we consider the use of the electromagnetic devices for the flow control and make the numerical research on the system. By setting the MHD generator and the MHD accelerator at the inlet and the nozzle of the SCRAM-jet engine, respectively, the flow inside the engine is appropriately controlled with small amount of the energy loss, when the flow has sufficient electric conductivity by the seeding technique. As the preliminary study, the two dimensional Euler analyses with MHD effects have been conducted to demonstrate that the inlet flow can be controlled by putting a MHD generator in the upstream region. From the analyses, it is confirmed that by setting the MHD generator and adding Lorenz force to the flow, the total pressure loss across the shock wave can be reduced, while the total pressure itself is decreased by the Lorenz force. To estimate the efficiency of such MHD energy-bypass SCRAM-jet engine, the totally coupled flow analysis of the inlet, combustion chamber and nozzle flows is necessary.
