Rolls-Royce RB.203 Trent
First run in December 1967, the Rolls-Royce RB.203 Trent was a British medium-bypass turbofan engine of around 10,000lb thrust, bearing no relation to the earlier Rolls-Royce RB.50 Trent turboprop or the later high bypass Rolls-Royce Trent turbofan.
The RB.203 was a private venture engine based around the core of the Rolls-Royce Turbomeca Adour turbofan used in the SEPECAT Jaguar and the later Hawker Siddeley Hawk.
The RB.203, the first three-spool engine, was intended as a civilian replacement for the earlier Rolls-Royce Spey.
Type: Three-spool medium bypass turbofan
