Trent 900
Here's a Trent 900 engine being assembled - inside are the turbine blades from the factory on the previous photo. This engine will eventually be one of 4 to power an Airbus A380. 
Here's a Rolls-Royce photo of the Airbus A380 flying over Derby. You can see the various Royce's buildings below and the dots on the playing field are people! 
Here's another Rolls-Royce photo showing the Airbus A380 from another angle on its fly past over the company's plant in Derby.
