Replica of a propeller from the USS Monitor. Since the introduction of the marine propeller in the early 19th century, cavitation during operation has been a limiting factor in the efficiency of ships. Cavitation in marine propellers develops when the propeller operates at a high speed and reduces the efficiency of the propeller.
McCauley Propeller Systems is an American aircraft propeller manufacturer, founded in Dayton, Ohio in 1938 by Ernest G. McCauley. [1] At its peak, it was reportedly the world's largest aircraft propeller manufacturer, [ 2 ] or at least the largest manufacturer of general aviation propellers.

The 121st Air Refueling Wing's Boeing KC-135 Stratotanker mission is to provide the core aerial refueling capability for the USAF and the Air National Guard.This unique aircraft enhances the Air Force's capability to accomplish its primary missions of Global Reach and Global Power.
Major places where cavitation occurs are in pumps, on propellers, or at restrictions in a flowing liquid. As an impeller's (in a pump) or propeller's (as in the case of a ship or submarine) blades move through a fluid, low-pressure areas are formed as the fluid accelerates around and moves past the blades.
The Voith Schneider propeller was originally a design for a hydro-electric turbine. [2] Its Austrian inventor, Ernst Schneider, had a chance meeting on a train with a manager at Voith's subsidiary St. Pölten works; this led to the turbine being investigated by Voith's engineers, who discovered that although it was no more efficient than other water turbines, Schneider's design worked well as ...

Cavitating propeller in water tunnel experiment Cavitation damage evident on the propeller of a personal watercraft Bronze propeller & anti-cavitation plate, & Schilling rudder (on a river barge) Cavitation is the formation of vapor bubbles in water near a moving propeller blade in regions of very low pressure. It can occur if an attempt is ...
