www.gasturbineworld.co.uk Worlds biggest back yard jet the mighty RR RB211! Brought to life by two APUs; A H & S Stad 250 (LP Starter MK12) and a Garrett GTCP85 BAC 1-11 APU
I flew as a young man with my father on an Air Canada L1011 to Europe with those exact 3 engines. My dream is not a Porche. But rather one of those beautiful engines in my family room. Their power, their roar, their elegance……. Yep… it’s a man’s stupid world. Cheers from Montreal,Canada….
In case nobody else said it, thank you guys for doing the work to get this gem working, and thank you for sharing with us. As for the tee-shirt, your wish may come true!
Wow. This thing used to run at high power, hour after hour at minus 50 degrees in the stratosphere, day in, day out. I know enough about jet engines to know the fuel burn at sea level, even at idle, is insane... good on you for doing this.
you guys are nuts getting that close hahaha RB211 is definitely one of the best engines ever made. So reliable and powerful, as well as sounding amazing.
OMG THATS THE COOLEST THING IVE EVER SEEN IN MY LIFE!!!!!!! as a kid i always imagined having a jet engine in my yard and showing it to all of my friends and making people think there was an airplane im so jealous rightnow im 18 ill study enough so one day ill be able to afford this^^
Great video! Love to see the old engines still running. I am not an engineer, but I was a ramp rat for many years. The guy with the camerahas a death wish or is completely oblivious to the power of an RB211 even at idle. Especially because the engine is mounted lower than when normally mounted on an L1011. @4:40 WTF!! Even a JT8D on a 737-200 can suck you in at idle. I'm the last person to talk safety but I had to add my 2 cents. Don't want to see such a cool project ruined by sucking in a guy and his camera equipment. However, that would make a viral video. :}
So true, I work on 757's and would never dare get that close to the inlet at idle let alone at power. You need to come from the side just aft of the gear box and forward of the c duct.
Isn't that the truth. I can't tell if he either has some brass cojones the size of watermelons, or is incredibly stupid. These guys and their equipment are way too close to the mouth of that turbofan, talk about reckless. I'm surprised dude didn't get turned into ground beef. That'd be like getting pulled into a wood chipper. When I saw that I thought holy hell, you did not just walk up to the mouth of a running turbofan. The close up video of that spinner isn't worth the risk of ingestion. Someone needs to show him the video of the aircraft carrier flight deck guy that approached an A-6 Intruder, that was on the catapult preparing for takeoff, and he was standing instead of stooping and got sucked into the intake. Lucky for him the airflow sensor caught his vest and only his helmet and goggles went through the engine causing it to spit blades and flames out the nozzle. The pilot shut it down and the guy was able to crawl back out. Said he could barely breath it was sucking so much air. His head was just inches from the intake stator vanes of that JT8A/J52-P8B turbojet.
This is by far the most ridiculous (and most fantastic) thing I've seen on RU-vid - you could only best it by firing a Saturn V rocket in that backyard. I was nearly without words until ... Question: what was the fuel cost of this "Spring Crank Up?" You folks have disposable income I'm quite jealous of. This video is by far a favourite, in no small part due to childhood nostalgia. In the late 70s - early 80s, I wandered the isles of the ElTenEleven during transatlantic flights - the parents traveled an awful lot. I still remember the terribly bad earphone audio of the in-flight videos, and the dual lead headphone jacks to watch the CRT RGB projection movies; I opted for the Casey Kasem narrated in-flight documentaries, using the analogue channel selector. All that to drown out the sweet music of these RR jet engines! How foolish. Good times.
Craig Arndt I think it’s time to try out a new and very quick way to remove the wool, produce a hide/sheepskin in recordime as well as butchering a fine stack of lamb chops even la few broken legs of lamb, using this most excellent RR Engine. I don’t think the farmer (owner of the sheep) would mind, how can anyone oppose the advancement in the food sciences/animal husbandry area. I think I’d feed the engine using a 40-50 foot conveyer belt assembly, the away end would be set 5 feet above the engine end allowing for a smooth gravity driven slope into the engine. I know this works, I saw it being done in a Roadrunner cartoon. The coyote set up a jet engine at the end of a long tunnel, the roadrunner is being chased by the coyote driving a corvette. There is a secret exit half way through the tunnel hidden by fake rocks, the coyote pushes a button the exit opens up he gets to the main highway while the roadrunner’s momentum and the engines vacuum carries him into the blades. Somehow things got messed up and the coyote runs into the engine while the roadrunner drives off in the corvette out the secret exit. The coyote was always getting screwed like that? BTW- How many gallons or pounds or Jet A did you burn the what 5-6 minutes the engine was running?
In another video you can see that they are using the main engine mounts to help support the engine in that trailer. I would still be leary of taking that much above idle, due to the chance of damaging the cases where the ground handling/trailer mounts attach. Not to mention it might end up in the next town sucking all that nice equipment in the intake as it heads off down the road. Love how the RB211-22 rumbles as it transitions to idle after it lights off, great sound.
Woking out on the ramp at JFK I know the sound of these all too well. These engines literally shook the ground upon start up, you felt it right in your chest. Yet this never happened with the DC10 or 747, wonder why .....
I just love this I am an Ex RAF aircraft engineer I worked on the VC10 flying test bed that developed the RB211! I love your set up - the old RAF Palouste starter trolley to start thew APU then the APU to start the RB211 superb work guys! The engine saved ROlls Royce and was the foreruner of the BEST engines in thw world - THE MIGHT TRENT series! Do you ever run her up to FULL TO/GA power?
Hope your good friends with the neighbors lol. This would ruin a quiet Sunday morning for about 20 miles around lol. I'd be so confused the first time I heard that off in the distance lol.
Joe's RC Planes Yeah, it wasn't a real startup... Just a fake video to show that they have the coolest toys... Why would anyone waste money on jet fuel to start up an engine in the middle of a fucking field???
Very impressive! I wonder if the engine can be heard in nearby Cardiff when it's run up on test? It would be very interesting to see and hear some of the rest of your remarkable collection - especially the smaller jet engines - Many thanks from Rob G3XFD.
I understand that the turbine blades in all jet engines are not rigid in their mounts, but allowed to 'wiggle' just a little to prevent some kind of oscillation. Would that be the rattling noise we hear on shut-down?
Well yes and no. The rattling you hear are the fan blades’ mid-span shrouds’ that are little bumper like objects that protrude from each fan blade that begin to contact each other as the centrifugal force reduces as the engine rotation slows.
That grinding sounds like some sort of slight contact between the blades and the coweling or rubbing on the compressor behind it 🤔 I've been on a tri star truly brilliant air craft air pressure release on landing was a bit vicious tho had a few nose bleeds around the cabin but all I got was ear ache lucky for me
I think I know a little about jet engines, and yet I'm at a loss for what is causing that scraping/rattling sound at the end on shut down. Blades contacting the cowling????
Why does the RB211 seem to require both a GSE air source and the APU air for start? The GTCP85 was used on some big aircraft; shouldn't it have been able to start the RB on its own?
