Fully-functional Rolls-Royce jet engine built out of 152,455 LEGO bricks

Building a Rolls-Royce Trent 1000 engine replica out of 152,455 standard LEGO bricks is quite a feat. The 307kg (677 pounds), 2 meters (6.6 feet) long and 1.5 meters (4.9 feet) wide LEGO Rolls-Royce jet engine was unveiled at the Farnborough International Airshow and is touted to be the ‘world’s most complex LEGO structure ever built’. Rolls-Royce says there were 160 separate engine components built and later assembled together to form the engine, which took a team of four geniuses eight weeks to complete.

The LEGO engine built by graduates and apprentices at Rolls-Royce is only half the size of the real Rolls-Royce Trent 1000 engine used in Boeing 787 Dreamliner, but is way too silent and fully-functional. The LEGO engine comes with large fan blades to suck in air to the combustion chambers and is decked out with all the innards of the Rolls-Royce jet engine making it a perfect engine to produce enough thrust to power a jet.
