Rolls-Royce’s Latest Jet Engine is Made Out of Legos

by philewing on July 10, 2012

FARNBOROUGH, England — Pentagon and defense industry leaders in the U.S. have a favorite, near-ubiquitous expression: They want to entice more kids into “STEM:” Science, technology, engineering and math. Future generations of engineers and scientists will be critical for DoD and its vendors to keep their edge, the thinking goes.

So too here in the U.K., where jet engine-builder Rolls-Royce accomplished a technical feat of its own to get kids interested in what is literally the high-speed world of jettery: It commissioned a scale Lego model of its Trent 1000 engine, which is on display at the air show.

Jet engines are fascinating and incredible machines, and Rolls’ Lego version makes what is usually a frightening and painfully noisy contraption a little easier to understand. Per the company, here were its stats:

The one of a kind Lego structure shows the complex inner workings of a jet engine and took four people eight weeks to complete. Including 152,455 Lego bricks, the engine weighs 307 kg and is over 2 meters long and 1.5 meters wide. Over 160 separate engine components were built and joined together in order to replicate a real jet engine. Everything from the large fan blades which suck air into the engine down to the combustion chambers where fuel is burned, had to be analysed and replicated using the world famous building blocks.

You don’t want to get too close to a real Trent 1000 when it’s turning and burning under the wing of a Boeing 787. The genuine article draws as much as 1.25 tons of air every second at takeoff, Rolls says; at that speed each of its 66 blades delivers about the same power as a Formula One car — about 800 horsepower per blade. The company’s fun facts conclude with this: “At full power air leaves the nozzle at the back of the engine travelling at almost 900 mph.”

This is horrible, this engine cant power anything. The only reason this guy is saying great things about it is because he is paid by the company that built it. This Rolls Royce engine is horrible, we would be far better off getting lego built engines built by GE, at least their lego engines are proven. There is no point in taking a huge step forward in lego built engines when a generation 4.5 lego engine will do. We could buy 3.5 GE built lego engines or 4 honeywell built lego engines for the same price as ONE RR lego engine. What a waste of money.

Pratt and Whitney Canada. Here today, in China tomorrow.

lol i though you were serious there for a second

I hear China's already stolen the plans for it and made a copy out of Regos (their reverse engineered Legos).

That's… actually prety cool.

kids these days with their legos and their jet engines…. in my day, all i had to play with was a plain old cats head and an old beer can.

Russia is planning to make a different engine to counter this new arrival.


Stan July 10, 2012 at 11:24 pm

I hear they are going with macaroni. Very practical.

and the fuel it runs on doubles as a rather tasty cream sauce.


Ross July 11, 2012 at 7:10 am

this just makes me want to get all my old lego out and attempt to better their creation with one of my own: medievalrobinhoodcowboypirateshipmegaCASTLE!

not get into science and industry.

but alas…pretty kewl.

You sure that isn't the alternate F-35 engine?


Adam July 11, 2012 at 2:53 pm

Would that be considered stealth?

If one particle cube breaks apart, you have multiple victims, great, they should mount it in Osprey, who know maybe it would be considered an improvement.

If you really want to teach kids something SIENTIFIC, Get it right . SIENTIFICLY SPEAKING, JET ENGINES DON'T SUCK AIR IN! They create a lack of Atmospheric pressure foreward of the first stage compressor via the rotation of the fan, which is forceing the air backwards into the combustion section. Atmospheric pressure is forcing the air into the inlet towards the compressor.

Learn to spell "scientific" and "scientifically". Then get back to us.

Isn't that what sucking is – creating a volume of reduced preasure so as to cause a fluid to move due to its high preasure towards the reduced preasure volume (this incudes gasses)


Roland July 12, 2012 at 10:36 am

It might chip loose..!


@explodingwalrus July 12, 2012 at 11:14 am

It's LEGO not Legos!!


IKnowIT July 12, 2012 at 5:38 pm

It is SOOO annoying that people don't know the plural of Lego is Lego, not freaking LegoS… I remember they used to tell you that in the package when you bought new Lego.. Okay, I will end my rant.


Betty Normal July 12, 2012 at 1:36 pm

What happens if you throw a frozen LOGO chicken through the engine?


Betty Normal July 12, 2012 at 1:37 pm

LEGO chicken…


Davenport July 17, 2012 at 5:19 am

Don't know but Doesn't the bird ingestion test centre in Derby back on to a Kentucky Fried Chiken Outlet ? I've always wondered…..
