Remember guys this engine is running at Idle, a 747 hardly moves when sat on its wheels at idle. The induced flow in front of the engine only extends a few meters in front of it. Across the face of the air intake there is of course significant induced flow and pressure drop but at idle its unlikely to suck you in but I'm not gonna try it!
+EinkOLED burning 5 gallons of jet fuel per min at idle or 33.8 gallons per min at take-off power at $5.12 per gallon = $173~ a min in fuel......yes that would get expensive very quick for even an exhibition run
No after 2:48 they shut off the air turbine starter, and the engine was running on fuel, you can tell, because a Text popped up that said the starter and bleed valves were closed, and at 3:40 the engine increased in throttle to flight idle.
gasturbine101 I disagree there is enough suction there at idle to pull you in ....... I have not done it but the example of the navy guy who got sucked in while setting the catapult case in point.
That is just how it should be - a quiet English engine running quietly in a quiet English country garden, with a few English gentlemen drinking mugs of tea that probably went cold while they were setting up ... thanks for sharing. Great video. Good thing it didn't backfire.
Luckily the RB211 isn't known for compressor stalling... well... not unless there's a severe defect with the compressor that would allow such an issue to occur... They are insanely reliable jet engines.
I want to comment something, but. This guy is legendary. He has an freaking 747 engine that he can just go and start up, just like someone else would do with an Chevy 350, but it’s a jet turbine.
Incredibly powerful- just look at the trees swaying in the thrust! Citrus growers could use these to keep their orchards frost-free on those nights when freezes are forecast. The moving, warm air current would prove very effective. But, I imagine what the fuel bill would be like after running one of these throughout the night!
I visited a man many years ago near Valpraiso Indiana that had the original horns that were removed from the QE2 (or possibly QM1...it's been a loooong time). They were MASSIVE. He told us about how he decided to give them a whirl one sunny summer Saturday afternoon. His air compressor provided a fraction of the air requirement to run them but he tried it anyway. He said there were reports of people hearing ship's horns over 20 miles away. THAT would have been almost as cool as a jumbo jet engine running in the back yard!
The RB211 was - is - one of the finest large aircraft engines ever built. I loved flying on the 757 with the RB's because the power to weight ratio was so high. Yes - 757 were overpowered!
Very cool! Cheers from the US of A! Been to the UK many times and loved every single moment there. Great land, great people! Anyway, my guess is you got this engine after it was no longer airworthy. Neat stuff! Thanks!
467v APU is a meaning with a computer component chip thats has a video grahpics of the computer and the proccessor to run the pc is combined to one bigger chip
I used to fly these on Boeing 757's with bleed valve issues. You had to put them in high idle by turning engine anti ice on under 18,000 feet on descent to keep them from rolling back on landing and catching on fire. Made flight spoilers a primary flight control.
Lads you cheered me up this was a fine video to watch lying in bed after a small accident at work trying to only watch videos that are good and inspirational im a joiner by trade but love aviation and what makes it fly. not every day do you see a 747 in your garden. Keep going next you will be upgrading to a larger engine. Keep it British. Good Luck Guys!!!
That was boss, and I definitely want one of those in my backyard. Aimlessly push up the throttle with complete disregard for all my neighbors around me.
I love turbines, having owned several, including a couple Boeing 502s and T53, among others. But I can't fathom what one would do with an engine this big. Sure is neat to watch though!
Very fascinating. But I can't stop wondering where you get all those "toys" from? I would think that even a defect RR jet engine would have an very high recycling value? Titanium blades etc.? Also I was a bit nervous because you have a lot of stuff near the suction side of the turbine.... and that the steel frame is strong enough to withstand the thrust. Well I guess if you have all this equipment then you know what you are doing. What is your intention? Learning? Having fun? This is a bit a bit of a different hobby than people printing miniature jet engine models on their 3d printers ;-)
I want one of these in my back yard too. Actually - all four would be nice. It will be a very good idea to bolt it down 'properly'. Could end in tears otherwise if it detaches from the rig/jig thing. These engines are definitely effective for blow drying the forest etc.
Nice, I was concerned for your camera person, once you get inside the air feed radius you can get sucked in without much warning! Presumably you either have neighbors very far away or they are very understanding :-).
What is that momentary low-frequency growl that is always heard on start-up (heard here between 0:10 and 0:17)? I only ever seem to notice it when I fly on RR-equipped aircraft.
