INTERACTION OF MASSES IN THE OPERATING PROCESS OF PULSE JET ENGINES 
AS A MEANS OF INCREASING THEIR THRUST EFFICIENCY

UDC 621.452

Experimental and calculational-theoretical studies have 
been made of the operating process of pulse jet engines. With certain 
combinations of parameters of the operating pulsations, the interaction 
of cyclic gas masses among themselves or with the external medium 
(with and without the ejector channel alike) is possible, which provides 
an increase in the thrust efficiency of the engine.
