Caldarola’s turbine would work like this: Air is sucked into two inlets on the rotor. This accelerates the air and flings it to the periphery (in the image of the prototype, this area is yellow), increasing the pressure. The high-pressure air flows through several (black) elbows into the (blue) cans. Fuel is then injected into the cans, either as a mist or a vapor, and ignited. Fuel ignition further raises the pressure of the air. This pushes the air out through nozzles into the turbines As it hits the turbines, they start spinning, driving the propellers. The turbines are connected to the rotor, so this configuration provides a constant-flow cycle.
