The Lockheed F-104 Starfighter Howl Explained | General Electric J-79 Nozzle

This video explains how the howl you hear of the F-104, F-4, B-58- Ect forms.
The nozzle models are made of Card stock slight hot glue, and masking tape.
Please tell me if it helped you, Comment rate sub!!! Thanks for your time!

Cool... Do you think this could work with an rc EDF jet without loosing thrust? would be cool to make one for rc jet for scale sound

[Helicopterpilot16]

@fillopygeesi I do, but I'm not too sure about thrust loss. I would love to find out becasue its what I really want to try!

Good Vid! I know its been awhile, but you could put the blower in another room and tape a vacuum hose to it, then just have an electrical plug in the room you are in and bring the free end of the vacuum hose and plug in the room you are filming in to do the experiment again. Then we would hear better the howl of the beast!

@SgtRum It may take me a bit, but I think I have a better setup than the blower I used before. I have a hairdryer motor (Ducted Fan) connected to a model train transformer. Therefore it is adjustable to a point. Its allot quieter than the blower. But I sure will do so. Thanks for watching! I will message you once it has been uploaded.

Great explanation on this! And the whole time I thought it had something to do with the intake side of the engine. So thanks for clearing that up for me! Learn something new everyday!

And a very good demonstration using the fan, it really did sound like a J-79 with the second nozzle you made.

@MrGtirob01 Thanks! your as Surprised as I was!

I love it! Thanks!

Cool!

[VIR092]

That was an excellent explanation!

Pretty cool! I'm surprised that the fact that the inner flow isn't faster doesn't make a difference...I mean, obviously the venturi speeds it up a bit, but not to anything like the jet velocity of a J-79. I'm pretty sure you're right that the out air flow is mostly for cooling, but it may add some thrust as well...you get cooler, denser air from the outside mixed with the hot exhaust, which would heat it up and cause a bit of expansion. Probably not much, but some.
