These Guys Are Crazy Enough To Start A Gigantic 747 Engine In Their Backyard – Watch The Trees
On A Rolls.
The Boeing 747 is just about the most popular aircraft on the planet, even people who don’t know planes can identify it. The 747 is a pretty big plane, able to achieve lift with a maximum payload of 154 tons and a wingspan of over 210 feet. A plane with such immense size needs quite a bit of power to get off the ground fortunately, it comes equipped with Rolls-Royce RB211 Engines to help with that.
“The RB211 differed from other engines in its class in having three instead of two shafts. Each shaft has a compressor on its forward end and a turbine on its aft end. This design permitted each compressor to run nearer its optimum speed and efficiency and reduced the number of blades and other parts required in the engine. The static thrust varied from 160 KN (36,000 pounds) to 245 KN (55,000 pounds).”

A couple of guys got their hands on a lone RB11 engine and rigged it up in their backyard. To the astonishment of everyone they actually got it to work when they hooked it up. I’ve got to warn you things get pretty crazy when they really get it going in this video.
