Rolls-Royce Conway

Rolls-Royces the Conway was first jet engine with a Nebenstrom, which was used in aviation. The first flight of the engine took place 1954 under a Avro Ashton. With the Handley PAGE Victor, the Vickers VC-10 was used and with some types Boeing 707 and the Douglas DC-8. It was one of the first jet engines with a MTBO of 10000 hours.

The engine was produced in some variants for the civilian and the military range. It was available also with reverse thrust mechanisms.

Opposite the past jet engines the Conway was clearly quieter and also consumption-more favorable. The bypass ratio was first still very small with 0,3. The thrust of the first series was with 77,6 kN, could be increased however in the course of the further development up to 97,8 kN.

The direction taken with the Nebenstrom proved as correct, and so became the Conway of the first genuine fan engine, which Rolls-Royce RB.178 displaces later and from the Rolls-Royce RB.211.

The Conway could not become generally accepted in the American market against the engines of Pratt & Whitney, and so economic success remained granting.
