The General Electric Company's "Advanced J-47" turbojet (left) for military planes is the same frame size as the current J-47 engines (right), power plant for top Air Force planes, but is far more powerful. Accessories, houses in the nose in current engines, have been placed underneath to provide a greater air inlet area for the compressor. GE engineers said the compressor of the new engine, designated the J-47-GE-21, combines high air flows, high pressure ratios and high efficiency with a minimum number of stages. The "21" is 36.75 inches in diameter and is 146 inches long.
