I just want to say thank you very much sir for all your vidios i have been watching your vidios for more than 3 years.even though i am from Ethiopia which i cant get everything i need you encureged me to tray to make my own jet engine which is a long shoot 😓.but you sir are so luky keep it up.
Hi, thanks for another great video 😊 Some questions, if I may What is the optic attached to the test rig? I noticed that spray pattern of the secondary nozzles hit the walls of the observation enclosure quite soon - I assume that the spray pattern will stay uniform if it starts out well? You said that the rig couldn't supply full pressure. Couldn't problems appear at higher pressure? Thanks again David PS - you have shown me that I could never be a jet mech - I'm such a klutz, I would drop at least half the nuts into the engine 😕
1 It's a sort of long range microscope with a protractor, so we can measure he angle of the cone of dispersion. 2 We are looking for pattern uniformity. We measure at 300 psi, and the fuel nozzle may see up to 1000 psi during operation of the engine. They are made of machined stainless steel, not graham crackers.
I was keeping a "professional" mind... But you missed the part where the fuel nozzle squirts it's special flui...Never mind... I will let myself out...--->>>
I have been watching your videos for years and they have inspired me to build many cool projects, I have built a couple Boeing 502's Solar t-41's and I have a couple small Williams W-27's apu's that has a separate compressor to supply load air for main engine start and I was thinking about ducting it to a home made afterburner. What do you think?
I assume the flow rig would have the capability to measure flow rate in addition to flow pattern. Or the flow rate would be on the file nozzle COC. Would it help optimize the combustion efficiency to install the fuel nozzles based on their flow rates? For example like putting lower flow rate nozzles at top half and the higher flow rate ones at the bottom.
Fuel nozzles are not adjustable, but they may wear or become partially blocked. These are new, so no wear. We are looking for blockage, and found none. Done.
Couple questions. You said you couldn't test the nozzles as hard as they would be normally used. How do you know the spray pattern remains intact at higher pressure? And second can we see an example of a bad nozzle on the test rig please? Thanks. Ah - I see others have the same questions. Thanks.
Wouldnt a rubber grommet on the top of the green plate for the fuel tester be ideal so the end of the nozzle isnt banging into anything metal on metal?
Try talking to the manufacturer. They are the only ones who will have blueprints. I doubt they will share. If you re doing a thesis on jet engine architecture, you don't need drawings so specific that they contain proprietary information, do you?
So, the incredible vagueness and mismatch between what you want and what you ask for is quite interesting. Pictures and diagrams on the subject of your interest are very common, and free to access.
Hello, I am designing a hybrid compressor scale turbine, axially attached to the centrifugal, but for the stators I don't know how many blades there have to be per stage, for example, the first stage, the 7-blade rotor and the 8-blade stator, and the second, the rotor 9 blades and the stator 10 and etc? Or do they have to be the same blades at all stages?
You can do whatever you want, but if you are designing an actual compressor, many more blades and vanes per stage are necessary. Is it a cartoon display model, or is is going to be an actual compressor?
@@AgentJayZ Real, and if you want, I can send you a picture of the design for say me if is good or not. On my jet turbine, I will put 3 axial stages and the last, the centrifugal compressor.
Are the fuel spray profiles always conical?(across different engines makes/types) It seams a cone would maximize and create optimal consistency in fuel surface area but just curious if others had been tried.
My home engine is axiel. The fuel secondary or HP fuel is fed into the main shaft (I can't think what RR call it without looking) but as the engine picks up speed the fuel is literally flung out (under pressure) into the combustion chamber. There is a separate fuel nozzle for starting, and again without looking I think that's about 120psi. It's a combined HE ignitor too. But unlike the Orenda, the primary turns off when the engine reaches idle. Flicking a switch closes the fuel bypass solenoid providing full pressure to the HP and the engine accelerates to full power. My engine was built the same year as those fuel nozzles.
Hey AgentJayZ, do you work on engines converted to run on natural gas or do the conversions? If so are the same nozzles being used in such application?
How long it takes to run out of fuel for Airbus 380? If this engine was turbo fan (modern ones) with the same power how much fuel would consumed? I want to know how much new jet engines become more efficient than the same power of the old turbo jet ones? I hope you got my mean!
I've never worked on or refueled a A380 but I can tell you about the B747-400. During flight each engine uses approximately: 2850 kg's/hour. 3585 litres/hour. 6280 lbs/hour. 750 gallons/hour. This does vary according to which brand of engine is used and also the S.G (specific gravity) of the fuel, temperature & altitude and weight of the aircraft. For total fuel used during a flight times these numbers by 4. The APU (Auxiliary power unit) uses about 200kg/hour or 255litres/hour.
Dear Asad, you have much to learn. I do think you will enjoy the process. If you start with any of the books I recommend in my video called Books!, you will increase you knowledge greatly.
Hey sir, I am making an 21mm/8 inch diameter, 5 stage compressor turbojet engine but the first stage of compressor is about 2 inches behind the intake (front end) of engine. Would it affect the performance?
The diameter of all dimensions is 60. Units are for weenies. You can't get to the moon with "fractions". Come on, man! After the winter solstice, the concept of "dimensions" is reversed, and only the lizard people can lead us to adequacy. Always remember the pledge we made thousands of generations ago, to our lizard overlords: Gnee, Flargle, Stroshnangle... Ho! Oh, baby... hit that again!
AgentJayZ, when you said the fuel pump on test bench can't provide full pressure, how much pressure does the fuel nozzle usually use when running. Talking about the secondary....I'm just curious, because I'm guessing it's a big number, fuel is power, and lots of power in a jet engine, meaning lots of fuel being squeezed through those nozzles. Thank you for your videos and passion. Your one my fav youtube channels, and my FAVORITE Canadian!!! Happy holidays!! -Brian

It is still available as an industrial process.

Good show. Thanks
Do the fuel nozzles use something like a pintle injector spray fuel out?
These don't contain a part called a pintle, but they spray fuel out.
Feeding the trolls at 2:08 I see, lol. Thanks for sharing!
What do they use to preserve the parts? Is it an oil of some sort or does it matter on what part is being preserved?
Some kind of light oil.

@AgentJayZ Thanks for the video. How did you learn to repair jet engines, through BCIT? I would love to learn more about your career!
I've made a couple videos about how i got to where I am. They will be easy to find for a motivated, interested individual.
@@AgentJayZ Got it, question 18. Thanks!
That test chamber looks like my weather...
Wouldnt a rubber grommet on the top of the green plate for the fuel tester be ideal so the end of the nozzle isnt banging into anything metal on metal?
Nothing is banging into anything. Did you notice that?
Lets hear about the avro arrow engine does it run?
Hello sir,
Love the work. I am looking for an engine layout of the f414, any idea where i can find it? For my thesis on turbine frame....

If you re doing a thesis on jet engine architecture, you don't need drawings so specific that they contain proprietary information, do you?
