Aug 1955


The results of a theoretical an experimental study of ram-jet diffuser flow pulsing, commonly referred to as a, buzz condition, with and without combustion are presented herein. The theoretical approach to the problem is a simplified treatment of the ram jet likened to act as a Helmholtz resonator.
