1. Introduction. In view of recent energy problems, the need arises 
for a propulsion system that is less expensive but offers 
higher performance than the propulsion systems currently in use. The 
pulse detonation engine (PDE) offers a possible solution. PDEs employ 
an air-breathing, constant-volume process marked by high pressure 
and temperatures. These are conditions with higher power densities 
than conventional engines [1]. Therefore investigation of the different 
stages of the PDE working cycle, and the detonation initiation process 
in particular, is of great importance. Gasdynamic initiation is very 
attractive because it does not require additional energy sources.
