Summary
This short nonfiction film depicts the intensive testing that goes into developing and producing aircraft propellers. It opens with the whirring or propeller blades. Animated diagrams show how the bite of the propeller moves it through the air and how the pitch determines the size of the bite. A trip through an airplane factory shows the manufacture of a satisfactory alloy. The rest of the process is painstaking hand work interspersed with dozens of careful inspections. The operation of the variable pitch mechanism and its use in taking off and cruising is shown. Then the propeller is assembled the complete job is tested for balance.
