The engine is a system of rotors with radial channels that work due to timing as the shock waves are generated and move through the system. To grasp what’s going on, consider a turbine with air going in one end and exhaust gas exiting the other, like a set of fans. The wave engine – it seems – is like a squirrel cage or centrifugal fan with the air coming in the center and exhaust leaving the perimeter. Seems simple . . . And it is. Simply Brilliant!
