The Rolls-Royce RB.50 Trent was the first Rolls-Royce turboprop engine.[1]

Design and development[edit]

The Trent was based on a concept provided by Sir Frank Whittle and was essentially a Derwent Mark II turbojet engine with an additional turbine stage[citation needed] driving a reduction gearbox (designed by A A Rubbra) connected to a five-bladed Rotol propeller. The Trent ran for 633 hours on test before being installed in a Gloster Meteor jet fighter which flew for the first time on 20 September 1945 at the start of a programme comprising 298 hours of flight tests.[2]
