This is honestly the end of an era, and kind of sad. Gotta give props to the designers, the 747 has been a great success.

No. No props, this is a jet.

That's why you have to *give* it props, duh!
nchoe123 t1_izf7opt wrote
the props are in the jet engine, right?
kyredemain t1_izfmr6s wrote
Yeah, but they call them "Turbines" because it sounds cooler.
saccrebleu t1_izga5ng wrote
Technically they call them fans. Props can have a turbine behind them too.

The blades in the jet engine don’t propel the plane. The exhaust jet does. The jet engine blade assemblies are compressors up front and turbines in the back.

But wasn't there a version proposed that was going to use propellers?
Edit: Apparently the never built 747-500 was indeed meant to be propllers

Won’t be on the 747, but the efficiency of the open rotor turbine engine is making a comeback: https://www.seattletimes.com/business/boeing-aerospace/ge-and-safran-tout-new-open-rotor-engine-future-for-sustainable-aviation/

50 years of keeping the people of the world moving around as needed. With a pretty clean track record for safety. End of an era 🫡

But it still has 30 years behind the leader when it comes to longevity in regular passenger service.

Who has the leading spot. Is it DC-3 or MD-80?
zap_p25 t1_izev86y wrote
DC-3

I got to design one repair for a DC-3 that one of the airlines runs for charity now. That was cool. Also very easy because fatigue isn't much of a concern without a pressurized cabin. If they had actually decided to re-engine MD-80s I think they could have operated practically forever. They are built like tanks. Also seems like the military will run B-52s until the end of time.

Checks B-52’s payload
You are correct.
abnrib t1_izifbwt wrote
The B-52, C-130, and CH-47 are all currently projected to have over a century in service by the time they retire the platforms.

They did, and then called it the Boeing 717.

End of an era, that was my first thought. Mom was a gate agent and I spent hours in the airport, every time one rolled up it was all “ooh, look at the big 747!” Good memories <3
