The first Trent - a Rolls-Royce RB.50 Trent on a test rig at Hucknall, in March 1945

The Rolls-Royce Trent or RB.50 was the world's first turboprop engine. It was based on a concept provided by Sir Frank Whittle and was essentially a Derwent Mark II turbojet engine with an additional turbine stage driving a reduction gearbox 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 program comprising 298 hours of flight tests.^[1]

There is some debate over the origin of the "RB" prefix - having originated from the "Rover-Barnoldswick" project and plant names from the original Rover gas turbine projects which were passed into Rolls-Royce hands, it is now generally accepted, albeit some would say erroneously, to refer to "Rolls-Barnoldswick".
