@ICESTRONG@ "Awsome example my friend, just graduated from Aviation Institute of Maintenance from Duluth Georgia, & I really enjoyed this video, thank you, explains very well more stuff regarding turbine engines."
@AgentJayZ i am from rolls royce actually and overheard something about not having adjustable wrench in the workshops from some technicians there.. dont know if thats true.. lol!
@izaatmusic The only reason not to use an adjustable wrench is to avoid rounding off the edges of the bolts or nuts. When you round off the edges is can complicate the removal of such items, and it also promotes corrosion.
I wish lock wiring was always that easy!! ;) Across the top of the bolt just makes sense. Plus it looks cool. I vote to make that the industry standard! Keep up the great vids!
When are you going to start this engine? Im a Packard car fan, and knew they subcontracted to GE to make this engine. Not a far fetch consindering that Packard had made aircraft engines before. Thanks for the vid !
@packardnut The conversion from a -25 to a -27 is a bit more involved than it at first appears. Some critical parts are on their way, and I'm hoping to fire this screaming stovepipe up by the last week of April... fingers crossed.
The J47 has more combat flying hours than any turbine engine in history.
And you knew that Packard built a lot of Merlins, eh?
@AgentJayZ Yep. RR was also having some bugs with the engine, and knew that Packard was the only American company with the engineering know how and prestige to tackle the job since Packard was the American equivalent to RR. Packard had to change all the fittings to SAE from Metric to fit American planes also. Packard was very adept at making all types of engines for Marine, Air, and Land.
All the hairs on my neck are standing up, I really miss the equipment, smell and atmosphere of the workshop, some of the best times of my life, great people, great machinery, thanks you took me right back there!
Curious to know, if you might know what grade of stainless steel they use in the combuster / burner chambers you have there. another question any idea what sort of fuel flow rate per injector would be pumped through one of those injectors at say 100% power, 75 % power. 50% power (US GPH) . I was reading the other day in a burner forum that as far as fuel oil burners go that kero actually has a lower BTU rating than diesel as far as thermal output goes, yet in turbines it seems its the opposite
@milesall1 This engine has 8 fuel nozzles and one old book says the total fuel consumption of the engine at max power (without an afterburner) is 17 gallons US per minute.
Kerosene has a bit more energy content per wieght than diesel, but it is more expensive. I don't know how the densities compare, so energy per gallon - ??
Don't know the metallurgy, but a properly designed combustor liner doesn't get that hot, so neither would the outer "can".
Fantastic job there Jay! You've upped the mark on this one! Absolutly amazing, thats alot of fuel! Its also fasinating that all that flame is contained in the combustor liners with that amount of fuel and this is an old and smallish turbine! Now its understandable how you get an oily coating from the exhaust of a running aviation turbine! What are the J47's destine for? You said one is from an F-86, is the new -25 a transplant or parts cadaver? Is the Spey an industrial? Cant wait for AB tests!
@mytmousemalibu The -25 is being converted to -27 configuration. The -27 may get some attention as well.
The Spey is an industrial, which is why it is smaller in diameter than expected. Keep in mind in this video the first stage of the compressor has been removed, so you're looking at stg 2 LPC.
I will do my best to be there and film the J79... everybody loves afterburners, right!
@AgentJayZ The J47 is a beautiful engine, the new one you guys have is spectacular in its new sheen... The whole turbine arangment is a bit odd. No stator? Those classic early jets never were real powerhouses. The B-47's had a struggling time taking off but still cool seeing smoky old jets! The Spey is pretty! Pretty good sized machine! Afterburners are man made thunder! There sonic crackle and their spectacular sight is music you can feel! A feeling thats just about addicting!
This is really nice! Thanks for making these videos.

is it true that one must not use an adjustable wrench when installing jet engines if you are following the aviation code?
izaatmusic 8 months ago
@izaatmusic One must not... gee, that sounds a lot like Rolls Royce.
This is not a Rolls Royce engine.
... Aviation code? You make it sound so mysterious and grand... There is no such thing as "the aviation code".

@izaatmusic The point of using the proper wrench is to avoid damaging expensive parts, particularly if you don't have any spares.

@izaatmusic and he only used the adjustable to hold the adjacent bolt and used the proper spanner to tighten the bolt

Great videography!...clear image.
No wonder these engines have such a large energy output...all that fuel pumped through the nozzles.
Would be interesting to get a closer look at how the nozzles are constructed,and what is critical to producing the right spray.
Also a close look at the fuel pump and that whole system!
Thanks
