Jet Fuel Nozzles II - Turbine Engines: A Closer Look

Where and how the fuel nozzles fit in a J47 turbojet engine.
We clean, test and install them in this classic GE second generation American jet engine - the first with an axial-flow compressor.
Six of these engines powered the Boeing B47, America's first nuclear jet bomber and the mainstay Of Strategic Air Command until the coming of the B52.

is it true that one must not use an adjustable wrench when installing jet engines if you are following the aviation code?

[AgentJayZ]

@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".

[packardnut]

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 !

[AgentJayZ]

@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?

Afterburner testing...can't wait. :)

[AgentJayZ]

@dtoften You've already seen my other afterburner videos?

[gdsnuff]

This is really nice! Thanks for making these videos.

[aeronazumu]

Thanks

[kel557]

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

[matzele747]

Hallo Sir

greetings from Hamburg Germany and thanks all these interesting Films and your exellent descptions .

[YoungJim409]

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

[tdorneles]

Excelente vid man, congrats!!

[j3rocketeer]

@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.

[theboarman]

your so fucking awesome

[stephmc111]

nice flag you got there eh

[Migueldeservantes]

Hey Don't U have a few Key chain turbines to spare? I'll go and get it for as long it doesn't weight more than 1500 pounds! ;-)

[ICESPACEMANGALAXY]

@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."

[izaatmusic]

@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!

[kevat310]

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!

[packardnut]

@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.

[hippie1022]

wow the jet engine mechanic got distracted and forgot to hook up a bracket I'm never going on a plane again

[PERIZ99]

Great stuff...Thanks !

[MrSunilmanjunath]

Thanks a lot Jay..I am learning a lot from your videos..Keep the good work going

[AgentJayZ]

@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".

[1BustedMyth]

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!
