Abstract

The results are given of an investigation into the starting of a wedge-shaped nozzle of a shock tube. It is shown that in the regime of starting with overexpansion the main losses of the working time are associated with the secondary shock wave and in the considered sections of the nozzle occupy about half the complete duration of the starting. The application of the results to the investigation of the starting of wedge-shaped nozzles of various geometries is discussed.
