In 1911 it presents a pulsejet with two valves, one for intake and another for exhaust.

“Ion Pulsejet”

-This information has been obtained through the AEHS "Torque Meter" magazine.

-The principle is that of the Casanova pulsejet since it also has an inlet valve and an outlet valve.

-The fuel control is simply by a tap, and the ignition spark is provided continuously by a generator (or magneto) driven by a propeller.

Later, in the new designs, the exhaust valve was replaced by a nozzle long enough to produce the "piston" effect of the burned gases and fresh air intake.

-From the length depended the resonance and cycles per second of the process.
