Japanese, Rolls to Develop New Engine
Tokyo—Agreement has been reached by a Japanese consortium and Rolls-Royce on joint development of a new turbofan engine, tentatively called XJB by the Japanese, with about 19,000 lb. thrust. A joint Anglo-Japanese design team at Bristol, England, will develop the new engine, which Rolls-Royce has been calling RB.432 (AW&ST NOV. 12, p. 155).
