Rolls-Royce RB.50 Trent

 

RR-RB50-Trent

 

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 driving a reduction gearbox (designed by A A Rubbra) connected to a five-bladed Rotol propeller. Experimental work with the Trent (RB.50) actually dated back to May 1944, when a WelIand was equipped with a spur-type reduction gear and tested for shaft horsepower. First run in June 1944, the Trent ran for 633 hours on test before being installed in a Gloster Meteor  (Trent 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.

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