PLANE ENGINES PRODUCE ELECTRICITY

Electricity

November 16, 1942

New airplane engines produce electricity during their test runs with this equipment developed by engineers of Pratt & Whitney Aircraft and General Electric.

Instead of turning a propeller, the engine turns a generator which pumps electricity into the plant power system. Lines run from the engine under test to dials and indicators within a soundproofed booth, where operators note the various readings to determine the performance.

Since the initial installations in one of Praff & Whitney Aircraft's New England plants, the system has been installed to help develop electric power in a number of engine factories in other parts of the country.
