ABSTRACT:
Radial impulse engine, pump, and compressor systems are disclosed herein. In one embodiment of the invention, an engine includes a first end wall portion spaced apart from a second end wall portion to at least partially define a combustion chamber therebetween. In this embodiment, the engine further includes a plurality of movable wall portions disposed between the first and second end wall portions. Each movable wall portion includes a cylindrical surface extending at least partially between a distal edge portion and a pivot axis. Upon ignition in the combustion chamber, the distal edge portion of each movable wall portion slides across the cylindrical surface of the adjacent movable wall portion as the movable wall portions pivot outwardly in unison about their respective pivot axes.
