I just realized that no one has made a video about afterburners that doesn't just say "inject fuel into exhaust, ignite fuel, jet goes fast." I appreciate the decent dive into what components are actully needed, and the inner workings of afterburners in general.

[TedConingsby]

Great explanation, thank you. The answer to your question at 5:50 is the Concorde🤙

[ahdofu]

I surmise others may have already pointed this out. The J58 engine on SR71 is more like a turbojet/ramjet engine as opposed to an afterburning turbojet.

I love watching this channel. Captain Joe’s explanations remind me of growing up, listening to my dad explain the systems in the passenger liners he flew. He could make what most would consider mundane, dry subjects wax so poetic that by the time he was done, you were convinced that there could be no other aspiration in life except aviation. So can Captain Joe, for that matter.

[stevekirk]

That has been a great series Joe - fascinating. Thank you.

[urishima]

Exhaust plums are my favorite, the perfect balance of sweet and sour.

[TheBillzilla]

The Bristol Olympus in the Concorde!
FWIW the burners were used on the Concorde when, as you said, transitioning to supersonic but they weren't turned off until accelerating through M 1.7

[greggbuker]

J79’s were used in the F4 Phantom II and the B58 Hustler too.

This is Truly An OUTSTANDING Informative videos Sir Cheers 👍👌🧐🍻

[iammrvain]

Joe, great to hear from you tonight. Be well.

[MartinIbert]

While I am certainly not debating that "a good pilot is always learning", I would maintain that "a good professional is always learning", pilot or not.

[ernestchew]

A great series to watch. Thanks, Joe!

[kentaylor]

A good pilot maybe always Learning bit of excellent pilot is teaching. Excellent video I learnt a lot keep teaching and learning

[thiagosorin]

Studying for my Aicraft Propulsion exam. Thanks for the great video (as always)

[RacerThieo]

Do you think AI could replace your job?
If so how soon?
Thanks, I really enjoy watching your video’s!!!
Good luck

[Nyck]

Fantastic video. Very well explanation about this kind of engines.

[FlyOmPrivate]

I definitely would love to come take a tour around these engines and share which museum has this available!

[Bilal-qixc]

hello Captain Joe,
i have an important question.
can you please make a video about the performance and physical characteristics of a 4-engine plane flying on 1 & 4 engine only, versus flying on 2 & 3 engine only (symmetrical flight); in terms of acceleration, high and low speed, AoA, maneuvering, climb, descend, etc.
thanks a lot 😊

[MattH-wgou]

Great video! I never even considered if the AB is in the turbine exhaust or bypass flow, or a blend. Just never thought about it!

Most modern (at least American) fighters dont have a set/specific time limit on AB use. What they do have is a speed limit, but more importantly, the boost pumps feeding the engines (out of the feed tanks) can outpace the transfer pumps refilling the feed tanks from other tanks, so if you stay in a low altitude, super high fuel flow state for too long, you can literally flame out due to feed tank exhaustion. The transfer pumps just cant keep the feed tanks full.
Imagine the boost/transfer pumps on the SR71!!
