The Rolls-Royce RB529 Contrafan was a high-thrust aircraft engine that Rolls-Royce proposed in the 1980s to power long-range wide-body airliners. It was designed to power the four-engine Boeing 747 at a cruise speed of Mach 0.9. Like the General Electric Unducted Fan, it would have had direct-drive contra-rotating fans in a pusher configuration with variable pitch blades capable of reverse thrust, but a cowl would have surrounded the fans of the engine, which the General Electric design lacked. Its engine core would have been similar in size to that of the Rolls-Royce RB211-535E4, the 40,100 pound-force turbofan that powered the Boeing 757. Flight International in September 1986 listed a maximum thrust of 60,000 pounds-force and a fan diameter of 140 inches. The article describes it as a proposal.
