RR Tyne test prep

[@MrLohatoolvebyte]

Jay, I think it's great that you have accumulated so many subscribers. You do a great job of elevating our collective turbo-jet challenged consciences. In a twisted way (pun intended) you have expanded my understanding of my own field of studying and preventing fire in buildings. There are lots of parallels and commonalities. Thank you so much.

Ahh the good old RR Tyne. Takes me back to when I was a child and my dad would take me to Liverpool airport to watch the aeroplanes. We used to get a Vickers Vanguard freighter in with 4 of those babies. In that instance they had some sort of extra compressor or generator or something which made the engines produce a very characteristic and unique whine when taxing or at idle....

[@JakeShep83]

I really enjoy your videos. Though I have know idea what most of the stuff is but I enjoy the explanation and everything else.

[@GIGABACHI]

2:33 Sounds GLORIOUS.

That close up of the engine nameplate with the site name 'Ansty' brought back memories of working there between 1962 and '82. The site is almost completely closed now, with only the Trent fan case fabrication facility still operating.

[@tourbillonturbineservices1100]

do you still work in RR

[@grahamj9101]

No, I moved from Ansty to Bristol in 1982 and took early retirement back in 2003: I then returned part-time for another three years.

[@grahamj9101]

I served my undergraduate apprenticeship there with Bristol Siddeley Engines, but found myself working for R-R when they took over in 1967. I was in the design office of R-R's Industrial and Marine Division at Ansty until I moved to R-R Bristol in 1982, hence my interest in the engines that AgentJayZ works on. There may still be a couple of brackets on that Marine Tyne, which I designed. I also worked on the Industrial Olympus, for which I designed the LP turbine blade of the 'C' rated engine, which is featured in several of AgentJayZ's videos. With a promotion, I became Project Design Leader on the Industrial RB211, which, I believe, he has worked on elsewhere.

[@tourbillonturbineservices1100]

thanks Grahamj9101 for you respond ,i am working in S&S in last 10 years and overhaul RR engines ,this Tyne overhaul was my latest solo project in S&S but i am looking for find some training courses to improve my capability "i finish my engineering degree in delft UVT in gas turbine design and working hands on in last 15 years but looks like i am kind of out of subject, i thought you can help since you are ex- Rolls Royce engineer thanks

[@paulcarter4689]

I was the EIC for the Marine Tyne at Rolls Royce in the mid 1970’s when we were developing the RMIC which was a 5240 hp

[@drubradley8821]

You played a trick on me... lol... I just fired up a ham sandwich for the 30 minute show... now, I'll be left in suspense ... I am looking forward to that test... There is for sure a different sound to these RR units... I can't wait to here the specs of one of these, if that is allowed, Dru

[@tourbillonturbineservices1100]

thanks Agent jay z ,this engine looks very good :)

[@BMRStudio]

I want this hairdryer in my backyard!

[@FabricatorFactory]

Cool. Wow that's loud. The fun part is to come. The only way to reinstall it in the ship is to rig it down its own exaust plenum. Enjoy. Do it have friction bearings such as the kingsberry or anti friction angular contact ball bearings? Great video. Great job.

[@grahamj9101]

In my experience of being involved in their design for the Royal Navy, the Marine Tyne, Marine Olympus and Marine Spey gas generators/engine change units were all installed and removed via their air intakes/downtakes. They are all aero engine derived and have rolling element bearings. Having said that, my memory may be at fault, but the Marine Tyne just might have a plain 'steady' bearing on the LP shaft. The power turbines of the Marine Olympus and Marine Spey had plain journal bearings and tilting pad thrust bearings, which I know as Michell bearings, also known as Kingsbury bearings. As you will have seen in the video, the power turbine of the Marine Tyne is part of the engine change unit. The aero engine has a three-stage LP turbine, driving both the LP compressor and the prop. The power split across the stages was such that it could conveniently be 'split' to give a single-stage LP turbine and a two-stage free power turbine, which has rolling element bearings. PS I've just thought of a possible exception in respect of the Marine Olympus. As I recall, the 'Invincible' class aircraft carriers (powered by four Marine Olympus) usually carried a spare gas generator in the engine room. Replacement could be done at sea and I believe that such a replacement was carried out during the Falklands conflict.

[@FabricatorFactory]

grahamj9101 thanks for the great info.

[@douro20]

Rolls-Royce is currently cutting over 4000 jobs in England, including over 2000 at Antsy, Coventry where this engine was assembled.

[@AgentJayZ]

This engine was assembled in Fort St. John, British Columbia.

[@grahamj9101]

For anyone wanting to see another R-R engine in action, check out Bloodhound Is Go - Newquay 2017. I was there.

[@michaelmooney3369]

just out of curiosity who actually owns the run cell? Maddex or S&S or both?

[@AgentJayZ]

The true owner is a mysterious entity, incorporating the spirits of all those who have passed through the great outer doors.

[@cletus_maximus4711]

Hey AgentJayz, I had a question about jet engines. I was wondering if it was possible to have turbine motor with an output shaft but also have a dual function as a turbojet....maybe a turbine engine with output shaft that can be disconnected from the main drive or maybe there's a turbine engine that has an output shaft that is just strong enough to serve both functions.

[@NBSV1]

Cletus_Maximus Those are two very different functions that wouldn’t easily transfer. If using the power to turn an output shaft the power turbine is going to use the power and you wouldn’t get much, if any, thrust. You also couldn’t just remove the load from the power turbine to try and gain thrust as that would quickly over speed the turbine. Maybe you could get into using bypass air as propulsion, but at that point you might as well make it a turbofan.

[@lukewashburn9639]

I know this is an old comment, but to a degree almost all engines are like this. There are various generators, fuel controls, oil pumps, starters, etc. mounted to an accessory pad on turbofan/jet engines.

[@drekor72]

4mins 19secs?!! What's this madness! 🤔😉😎

[@AgentJayZ]

Thanks. This is a video meant to show progress to those who may be curious about our Tyne testing facility.

[@grahamj9101]

Very curious!

[@AgentJayZ]

To the naysayers, I say: Nay!

[@oisiaa]

How's the test going to work with the exhaust going straight up into the roof?

[@AgentJayZ]

The 90 and the long pipe were not installed yet when this was recorded.

[@american0153]

Nice

[@CDhn455]

Sorry. I have a second question. Why was the data plate at the end of the video blank? No model number, serial number, or weight?

[@AgentJayZ]

The data is on there, just very hard to see.

[@fredflintstone2621]

Hello Agentwould there be a significant difference in service hours between an air worthy jet engine vs say a ground based power turbine and what is the service interval of such a device. thanks Pr

[@AgentJayZ]

As discussed quite a bit in my playlist your Questions Answered, industrial versions of aircraft engines, the so-called aeroderivative designs, do run much longer between service or overhauls than the flying ones.

[@bittechslow]

Hi AJZ,just watched this video,737 Manual Start,what's this all about then.

[@atubebuff]

I'm always amazed that there never seems to be much concern for an uncontained-rapid-disassembly of these engines. Losing blades or having oil pumps/seals fail has to be pretty dramatic, no?

[@AgentJayZ]

+Mac Delaney No

[@atubebuff]

So a blade simply detaches and just falls to the floor? An oil seal fails and there's no oil fire and sparks everywhere? Call me skeptical.

[@AgentJayZ]

In ten years of testing, I've never seen a blade detach. Seen lots of oil seals fail ; never seen an oil fire. My lube system video tries to show how oil seals work and how they are not the last barrier to oil escaping into the gas path.

[@CDhn455]

After the bleed air from the start cart was fed to the engine starter at about the 2 minute mark, what was the safety cable for that Electron Bill pulled on? Was there a slipblind or something preventing the air from reaching the engine starter that he opened?

[@CDhn455]

Ok. I just realized my guess was wrong. As soon as the bleed air from the start cart was turned on, the compressor rotor started turning right away. Was the safety cable attached to a fuel valve?

[@AgentJayZ]

We have attached a manual pull cord to what RR calls the fuel cock. It's a valve to allow or stop fuel flow to the main fuel control. It has a third position that allows draining fuel pressure before closing on engine shutdown. Bill is moving the valve from off to on once sufficient rpm is reached to allow the fuel pumps to function.

[@CDhn455]

Thank you very much for the videos and additional answers. Much appreciated all around!

[@Kovboi]

Hey Jay, was the RR Dart ever used as an industrial/ship engine? Those things sure screamed!

[@grahamj9101]

As a former R-R Industrial and Marine employee, I'm not aware of any such application for the Dart. The Proteus turboprop was, of course, used in various industrial and marine applications.

[@jcims]

What kind of fuel do they typically use in a marine application?

[@AgentJayZ]

This one runs on diesel fuel. There is no "typical".

[@grahamj9101]

R-R marine engines were specifically designed to run on 'Class A' diesel fuel to a UK DERD military specification.

[@th3d3wd3r]

I actually live right next to the river tyne

[@th3d3wd3r]

Also the old rolls royce factory where this engine was probably made is within spitting distance of where I live. People in Newcastle had quite the sense of pride with our engineering prowess. Not so much these days.

[@AgentJayZ]

Featured in the Dire Straits song "Southbound Again"...

[@th3d3wd3r]

AgentJayZ indeed it is! Fantastic song too. Love a bit of dire straits. I often ride through Cullercoats and past Spanish city too, or what was Spanish city. Whitley bay is a beautiful place.
