Both of these came into common use before modern computer control systems: propellers were used on the Monitor... and the Merrimac in 1865; water jets became common in the 1960s. By the late 1960s, the venerable SR-71 on the left incorporated controllable inlets, several internal flow controls...

IntelliJet addresses all of these efficiency issues by using a controllable pitch propeller pump, a controllable... efficiently, so the motor delivers more shaft power for the fuel it consumes; and 2) it controls the flow of water through the propeller, so the propeller converts more shaft power... and loads. In fact, some people commonly change propellers for carrying different loads or running at different speeds. Larger boats and ships like US Coast Guard Cutters use controllable...
