ABSTRACT:
A pulse combustor having a casing defining a combustion chamber and an exhaust region encircling the combustion chamber. A carburetor is coupled to the casing with an injector for injecting a fuel mixture into the combustion chamber in response to a pressure reduction following combustion in the combustion chamber. An ignitor for initially igniting the fuel mixture in the combustion chamber is provided. Following ignition and a rapid increase in pressure and temperature in the combustion chamber a pressure wave expands radially travelling along the exhaust region and then reversing direction in response to subsequent pressure reduction in the combustion chamber. After a fresh fuel mixture has been injected during the low pressure period it is pre-compressed by the pressure wave together with at least some of the hot residue from the previous combustion and then again ignites, repeating the cycle. The casing is cooled to enhance the pressure drop during the pressure reduction stage.
