Can I just add that the lock plates also act as sealing plates to prevent excessive under-platform leakage. This principle is very typically 'Derby', in respect of R-R engines. Compare and contrast this with what you will be familiar with on the (very Bristolian) Industrial Olympus LP turbine, which has a retaining tang at the front end of the firtree root and a little locking tab that gets bent over at the rear (the 593 LP turbine is exactly the same). With the design of the Olympus 'C' rated LPT blades, we had to stick sealing plates onto the front faces of the firtree roots, because, with the redesigned blades, the lug extensions at the back of the disc firtree lobes didn't provide adequate sealing.

Hi I'm really enjoying your vids. I'm not a machinist or mechanic but do enjoy high quality bits an pieces and the precision involved. I do have a question regarding high bypass fans on commercial airliners. I understand the workings but it appears to me that a lot of the hardware and plumbing of the engine itself is exposed to the flow of the fan. Is this the case and if so does this effect the smooth flow and expose components to damage? Cheers Rob
@AgentJayZ
@AgentJayZ 8 жыл бұрын
+05Cat28 Many newer airliner newer engines have a cowling around the core, but you are right - many earlier turbofans had a lot of drag-ey stuff just hanging out in the high speed breeze. This has puzzled a lot of us for years. The best person to answer that one is a turbine engine design engineer. I suspect one will magically appear soon to enlighten us...
@grahamj9101
@grahamj9101 8 жыл бұрын
+AgentJayZ Are you dropping a hint in my direction, AgentJayZ? All of the high by-pass turbofans, whether small, medium or large, that I have come across do have cowled/faired cores. Many of them (but not the R-R RB211/Trent range - and several others) have the gearbox and the accessories mounted on the core. It is both necessary (for protection) and beneficial (in terms of drag reduction) to have all that 'gubbins' (quaint UK English word!) covered by fairings. Equally, the low by-pass turbofans, whether ancient or modern, that I have come across typically do not have fairings around the core. However, all that 'gubbins' stuff is typically mounted on the outer casings and there are relatively fewer things in the way of the by-pass flow, which, in any case, is diffused to a lower velocity downstream of the fan. OK, there are a few fuel, oil and air tubes crossing the by-pass duct, plus a few flanges protruding into the by-pass flow. Nevertheless, some aerodynamicist and/or performance engineer (not me - I just designed the machinery) must have done the sums and decided that the losses weren't worth the trouble of the additional weight and cost of fairings. To digress slightly, I am aware of a Russian military turbofan that has a tubular air-to-air heat exchanger in its by-pass duct, which must cause significant blockage. The resultant losses must be worth the additional cooling available to the turbine (I assume), otherwise it wouldn't have been incorporated in the duct.

Haha funny. I trust and respect you massively Jay, but I think it's funny mentioning the gentleness of the use of a hammer in jet engines because every part is precious, rare, and delicate, then using a hammer to pound one of the rare pieces into position. Doesn't bending the part and pounding it back in cause metal fatigue making it unusable for more than a couple rounds of overhauls? If installing it is that indelicate a process, how do you extract them in the first place? Does it equally require bending one out to get them all removed? And with what, a screwdriver? Also, I think I've watched virtually all of your videos and have never spotted the framed print I sent you. Is it in the shop or did you take it home? ;) Love your videos and your awesome demonstration skills. You're a natural teacher and should consider teaching mechanic school when you retire from pounding locking plates. :)

+Bill Clark The balance arbor - the metal shaft to which the disc is mounted, was balanced as close to zero before use. I took a day, to the point where the machine was asking for 0.07 grams of weight to be applied. I used a tiny piece of tape, that I had to keep checking was still there. I wrote the mass and traced the location on the shaft in felt pen, and hopefully assumed the ink was an insignificant mass.

AgentJayZ, how does a Zero Stage work ? I did try to understand that it adds zero compression to the jet engine but how does it add overall pressure rise to a jet engine (thus boosting an older jet engine design) ?
@AgentJayZ
@AgentJayZ 8 жыл бұрын
+BillyNoMates1974 What is a zero stage? When an established design is updated and uprated, sometimes an additional stage is added to the front of the compressor to boost airflow. Instead of renaming all of the other stages so that the new stage is called "stage 1", the new stage is called stage zero. This avoids much confusion because all the parts that were already in the design keep the names they already have. So a zero stage is just a naming convention.

Another bit of information which you might find interesting (or useless, depending on your point of view) is the fact that, when we deleted the fan and LP turbine from the 3-shaft RB211 aero engine, to produce the 2-shaft Industrial B211, we did not rename the IP compressor and turbine and their component parts, to avoid confusion.

A Hammer and drift/punch is OK, but I would think using a 'C' clamp as a press would be less prone to 'It slipped and I broke some else.'

+Robert Albert Thank you for your assessment of my technique, however, "slipped and broke something else" may apply more to your technique...

9:04 why brass why not any other material like iron

@AgentJayZ 2 жыл бұрын
The punch is made of a material softer than the parts you are beating on, so any damage happens to the punch. Brass is one step harder than aluminum, but still softer than steel. A steel punch is used only as a last resort, and with extreme care. Only hacks and complete idiots hit engine parts directly with a steel hammer.

Hello Jay; I see your point about a lot of effort just to stop axial movement! Speaking of Rolls Royce, have you heard from grahamj9101 lately? His absence seems odd so hope he is OK. Thanks for showing this technique & no, I don't deserve these secret tidbits. I have some mechanical talent but I am a hack at gas turbine engines in comparison to you. A couple of friends & I have the J44's hot section off and that cooked turbine nozzle out. We all admired this 'different' engineering, even with this simple, 'disposable' design! Thanks for the education. DD

+Darren Duncan Hi Darren/everyone. Yes, I'm back in circulation, having been out to the Caribbean for a couple of weeks' sailing. However, I came back to commitments to support several STEM and Bloodhound Ambassador events, which meant that I had to get my PowerPoint presentations updated. I had fun on Wednesday, demonstrating my water-powered rockets, made from 2 litre (you'd say 'soda'?) bottles. With 4 atmos pressure, they will comfortably clear the length of a football (soccer to you) field. I'm off again to foreign parts (Wales) next week for another event. I also have other professional and domestic (like being a Grandpa) commitments, which keep me busy. I keep getting nudges to set up my own channel, but much of my time is already taken up. OK, I'll give it serious consideration, but first I need to get a camcorder and get in some practice.

I've been looking at camcorders - any advice? However, I must start counting the pennies, as I've got two trips to Singapore planned, another grandchild on the way, and thoughts of replacing my car next year.

+grahamj9101 Good to hear from you G. J.; I will encourage you to work-up a Y. T. channel, complete with Power Point, to share some of your knowledge. Heck, get a Go Pro with a waterproof case and show us some sailing! This would contrast nicely with Jay's river racing boats! Take care and to use some good ol' 'country' grammar, "Your comment has done been liked." ; )

There is a procedure, written by the manufacturer. Failure to follow that procedure will result in you being reassigned. You only get a couple chances, and then you are out.
