152,455-Piece Rolls-Royce Engine Is the Most Complex Lego Machine Ever Built
Jesus Diaz



This is insane. 152,455 Lego bricks, 677 pounds (307 kilograms) and 6.56 feet long (2 meters). That's how amazing this Lego cut-out of a Rolls-Royce Trent 1000 engine is. It has over 160 separate engine components just arranged like the engine that power the Boeing 787 Dreamliner.

Rolls-Royce—who presented their Lego engine yesterday at the Farnborough International Airshow—says that it took four people eight weeks to complete, which is quite a feat. The beautiful cut-out shows every detail of the inner workings of the engine, "including everything from the large fan blades which suck air into the engine down to the combustion chambers where fuel is burned." It required the builders to go through the actual CAD plans of the engine to reproduce every component accurately with Lego pieces.

According to them, it's the first of its kind in the world. Still, it's only half the size of the actual engine, which weighs 1.25 tons.
