Design and development

The Trent was based on a concept by Sir Frank Whittle. It was a Derwent Mark II turbojet engine with a cropped impeller (turbine unchanged)[2] and 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 298-hour flight test programme.[3]

Performance

gollark: Okay, so make it not crash, people will OBVIOUSLY crash it HORRIBLY all the time.
gollark: You should make the thing not crash, too.
gollark: it did not, in fact, give me unused sessions.
gollark: Apparently if I wipe the cookie it just assigns me another session which someone may already have!
gollark: > but you can at least build arbitrary pure expressions using the free variable button and bindingYou can?
