Refer back to your comments on tuning. The original work done on PDE's
indicated a very low rep rate was possible, far less than a pulse jet.
That may have changed since the 70's however.

Any fuel, mixed with air, has a range of concentrations over which the
mixture is explosive. For acetylene the range is *extremely* wide, most
unusually so.

Mixed gases are not allowed to accumulate, at least not in a properly-
running torch. They're burned as they mix.
