INITIATION OF DETONATION BY GASDYNAMIC METHODS

With the recent energetic problems, a need arises for a propulsion 
concept that is less expensive but offers higher performance than 
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. 
The gasdynamic initiation is very attractive because it does not require 
additional energy sources.
