General information :
In the mid 1970s, Boeing was considering designs for a new twin-engined aircraft to replace its successful 727 . As the size of the proposed plane grew from 150 passengers towards 200, Rolls-Royce realised that the RB211 could be adapted by reducing the diameter of the fan and removing the first IP compressor stage to produce an engine with the necessary 37,400 lbf (166,000 N) thrust. The new version was designated RB211-535. On 31 August 1978 Eastern Airlines and British Airways announced orders for the new 757 , powered by the -535. Designated RB211-535C, the engine entered service in January 1983. This was the first time that Rolls-Royce had provided a launch engine on a Boeing aircraft. Eastern Airlines president Frank Borman called the -535C "The finest airline engine in the world". (source Wikipedia)
