Abstract
Unsteady outflow from a sonic nozzle with off-design factor 4 · 108 at an ambient pressure of 2 · 10−5 mm Hg is studied by means of the absorption of an electron beam. The motion laws of the front of the outflowing gas and other characteristic regions of the outflow are studied. A comparison to the results of other works clarifies the features of outflow with high offdesign factors. An equation is obtained describing the motion of the front of outflowing gas along the flow axis. Results are presented in generalized similitude parameters.
