Rolls royce avon 200 Videos

man buddy, you guys up there at red neck turbines got balls of steel, i cant believe you sat beside it while it lights off, mind you i guess it is not unlike hitting the ignitor box with a hammer LOL, that ESN sounds familiar though!!!!!!

AgentJayZ; I noticed that on almost all the bolts used on this AVON engine that there was a distinct lack of bolt lock wires in use, is there a specific reason that RR does not use them on this engine? Love the videos I have watched every one, keep it up they are great.

+AgentJayZ Hey Jay, just wondering are the bearings of the engine preloaded with a torque value? Or are they set to have a minimal amount of free play? Or can it be done either way dependant on the manufacturers specifications? Thanks!

Bleed here, bleed there - all the possible bleed air together, how much is it compared to the total amount of air rushing through the engine? Does this have any noticeable effect on the engine's power output when bleed valves are opening / closing?

Can you do a video on the J58 engine ? Yes the Avon is Sweet !

Why are there winding pig tails instead of direct shorter L shape pipes?

Hello JayZ is there any specific device to maintain constant pressure in the combustion chamber?

Another comment (more coming), I used to control axial compressors in refineries and one of our jobs was to avoid "surge", a situation you described very well and I could understand it for the first time thanks to your explanation. We were given the data of the "surge line" and if the compressor ever went near that line our control system would open a bypass valve feeding part of the outlet flow to the inlet pipe, thus increasing flow through the compressor. That would be the function of the compressor bleed valve in a jet engine, I guess. We were not allowed to bleed flammable gases like hydrogen or natural gas to the atmosphere :). By the way, the most widely used thread here in Argentina is Withworth. You go to a hardware store and ask for a 1/4" UNC bolt and they will give you a 1/4 BSW (Withworth Coarse) saying "it's the same diameter and pitch". "Yes, but the thread profile is different". Silence...

Hi Jay, I know I am watching an older valve but in doing so it got me thinking. I am wondering when jet engines go from flight engines to industrial engines you do away with a lot of extra like wing deicing and cabin bleed as well as many others. My question is by eliminating all this bleed air and exhaust air before the power turbine, does this in turn increase the available power (energy) of the engine? Would the compressor give more pressure since none or less is being removed out of the path for other uses? Thanks Jay

The stabilizing valve at 3:10, is that included because the air flow through the Compressor bleed valve is turbulent at the edges of the rectangular openings and the whole moving structure could oscillate at some point? Hence the stabilization valve is a damper( shock absorber) to these oscillation I guess. It is rather scaring to know how much those carbon sliders cost, as I am not in the aircraft maintenance profession. Great detail, thank you,

I think I've only seen you use a torque wrench once. At work, we do pumps and gearboxes, and nearly every bolt has a torque. Do you do this off camera or is it different for old engines?

How does the engine determine when to close the bleed valves? You mention it's hydraulic-mechanically controlled, but what controls that in the first place? Thanks

Got it.. but after watching the video a few more times, if my understanding is correct the ratchet piece at high rpm's doesn't touch the starter housing, but doesn't it still spin with the main shaft of the engine? And if so i would imagine that it rides on a bearing? and further aren't most main bearings cooled in some way? i ask because i can imagine that if that spins with the main shaft at such rpm's it will get quite hot and i don't believe just air cooling would be enough? thanks..

However, I'm not so convinced it isn't a fake. There is no convincing evidence of any heat behind the plane. No heat haze. The sound is also very clean. Not that it matters; film makers often add sound to an image post production - it's often cheaper, safer and easier to produce the required effect. In this case the sound fits the image to produce the appearance of a Hunter at startup. Weather that appearance is true or false is really rather irrelevant. Hate 500 character limit ;-)

Hi, I'm having a slight issue with the 1-11 soundpack installed on my US Air 1-11 I have tried this on another 1-11 variant how ever, there's no change. The problem is, I still have the original engine sound which came with the aircraft when I first installed it. Every time I throttle to around 1/2 the engine sound changes to the new sound pack, and it will continue to stay that way unless I throttle down to idle, or switch to VC an back to the outside view. Any help please?

Saw this jet car at Santapod at the weekend (11th July 2015) sadly in a bad state, //www.solent-renegades.co.uk/members/sarah-albums-dragstalgia-2015-a-picture54285-140.html great to see this video and see the car run.
