Straight Shocks - Supersonic Wind Tunnel Operation

This lecture covers the operation of a supersonic wind tunnel with straight shocks, discussing the effects of back pressure and the use of a single blower. The instructor explains how to achieve a permanent shock-free flow and optimize the test conditions by adjusting the rear pressure. Various scenarios are explored, such as the impact of reducing the second pass and the possibility of eliminating the shock wave by manipulating the nozzle flows. Practical applications are demonstrated, showing how to control shocks and improve the performance of the wind tunnel.
