he conditions needed to stimulate harmonic self-excited 
oscillations in frontal combustion of a fuel mixture in the throat 
or cavity of a Helmhholtz resonator are considered. It is shown that 
they depend on the properties of the fuel mixture and the position 
and orientation of the front of the flame and can be satisfied only 
in the presence in the zone of combustion of a surface of discontinuity 
of the parameters that determine the rate of combustion. It is noted 
that the results of analysis do not come into conflict with the facts 
and dependences that are observed in combustion of fuel mixtures in 
tunnel burners, piston carburetors, and rocket engines.
