The General Electric Company's newest jet engine, the same size as the company's present battle tested jet but far more powerful, is prepared for the test at GE Lockland Ohio plant. Designated the J-47-GE-21, and the first of the Advanced J-47 series, it is designed for advanced military aircraft. Although its power could not be revealed, it puts out far more thrust than the current J-47 engines - rated in excess of 5,200 pounds - in Air Force planes. Accessories, housed in the nose in present engines, have been placed underneath to provide a greater air inlet area to the compressor. GE engineers said the compressor combines air flows, high pressure ratios and high efficiency with a minimum number of stages. The engine is 36.75 inches in diameter and is 146 inches long.
