• An experimental study has been performed of the starting process of a supersonic Ludwieg tube with a diaphragm or a quick-opening valve located downstream of the nozzle. The starting times of the steady flow in the supply tube and in the nozzle are compared with the results of the upstream valve configuration reported in the previous paper. The starting process of the nozzles with a downstream valve is calculated by a method of one-dimensional characteristics, assuming an instantaneous opening of the valve, and the mechanism of the starting process is discussed for the case where starting shock waves are produced and for the case where a supersonic flow is established in the nozzle without producing the shock waves.
