Abstract
A compressor and method are provided, the compressor having elliptically-shaped combustion chambers including a first chamber having a first inlet and a first outlet, and a last chamber having an inlet and outlet. The first inlet is in communication with a low pressure plenum, the first outlet is in communication with the inlet of the last chamber, and the outlet of the last chamber is in communication with a high pressure plenum to define a flow pathway. A volume of gas is introduced into the first chamber at a first pressure. A fuel is injected into the first chamber, alternately at the foci, and ignited to advance the volume of gas along the flow pathway. A fuel is injected into the last chamber, alternately at the foci, and ignited on a schedule synchronized with ignition in the first chamber to further advance the volume of gas along the flow pathway.
