JUNE 1982 AIRCRAFT ENGINEERING 11 Progress with Advanced Engine for Boeing 757 Airliners Test running is in progress with a 535E4 development engine with a high-efficiency wide- chord fan. This engine is being developed for service in Boeing 757 airliners from 1984. Its advanced fan incorporates technology unique to Rolls-Royce. Recent testing has shown that this new fan reduces fuel consumption by over 2½% compared with the earlier design of fan on the initial 535C engine. This test running forms part of the 535E4 development programme which began last year. The engine is scheduled to enter service in 1984 and nil! provide a further ten per cent reduction in fuel consumption for Boeing 757s compared to the 535C. The earlier 535C version was certificated in 1981 and will enter service early next year powering Boeing 757 airliners. Boeing has reported that test-flying with 535C-powered 757s is indicating a fuel efficiency better than wind-tunnel test predictions. The wide-chord fan is only one of a range of advanced features contributing towards the improved fuel burn of the 535E4. As well as the wide-chord fan, they include more efficient compressors and turbines and an integrated exhaust nozzle through which both the hot and cold jet flows leave the engine.

As well as reducing fuel consumption by 2½%, it provides higher thrust levels and better resistance to bird strikes than the earlier fan.
