we have to call it a "fan" because heaven forbid we call it a "propeller," that's what my grandpa flew, lol

>>2064849
>techbro learns about ducted fans but calls the duct bloat

Propfan bros we're so bacck

>>2064849
> blades extend below fuselage
imagine the belly landings...

>>2064849
these cfnm fans have been around forever, what changed to make them viable now?

>>2064849
>props always been more efficient than jets
When nature is trying to tell you something: listen: stop pointlessly moving around and stop wanting to do it faster. There is a penalty.

>>2065116
look, you don't have to say that props aren't good. yeah prop planes can't go supersonic. the solution is to enclose the props in a medium where the speed of sound happens to be way fucking higher

The output of a single A400M engine is roughly equivalent to that of a CFM56, so why not build a turboprop passenger aircraft comparable to the B737 class?
There are many routes, like those to remote islands, where economy is more important than speed.

>just put the propeller in a tube to go faster lol
aviation industry is troll science

I thought he was being cheeky and saying,
>Keep propellers on boats

>>2065167
People will sit in a airport for hours to go 600mph for such a shorter trip time....meanwhile they could have slept on a train or boat, or flew on a far less engineered plane with less hassle.

Why does anyone need to be anywhere fast as a plane? The all need kidney operations?

>>2065205
>Need, need, need
You're a patronizing jerk off trying tell everyone how they should live. You have no idea what people need, much less what they want. Nobody is going to listen to a limp wristed, snot nosed, "urbanist," with a deeply misplaced sense of superiority.

Computer simulation became better, and they used the better simulation to figure out how to drastically reduce the noise while maintaining power output. Previously, the one of the reasons why they gave up on propfan in the late 80s was much higher noise level compared to turbofan.

>>2065205
Pissed off that this crazy idea of degenerationism is gaining traction because of that SWEDISH RETARD GIRL.
Go back living standards of 100 years ago?

>>2065229
Why is the military not using them? I doubt they care about noise levels

>>2065240
They don't care about fuel efficiency either

a modern civil jet engine is literally "what if we took a turbocharged engine, but put everything in the wrong order"

>>2065192
they literally do this, "feeder fights" are mostly small turboprops that might not carry a lot of people but one airframe does like 30 flights a day

they dont make big planes that do it because it's actually not economical; not that many people need to go to the same place at the same time, so it's better to have a bunch of things like picrel basically acting like a bus route doing lots of low passenger count flights but doing them at all fucking hours and maintaining a similar throughput to one giganigga flat fuck Herc wannabe

>>2065240
not only >>2065241 but military airlift is peak "This THING needs to be OVER THERE and it needs to be RIGHT NOW"
when that isn't the case, most western militaries gladly just ship shit through normal post and if it's something they can't they plonk it on a truck or ship because even in poorfag shitholes the military always has infinite money somehow

>>2065098
Govt environmental regulations. (Civilisational decline).

>>2065205
>meanwhile they could have slept on a train or boat
For triple the price.
I would gladly take Amtrak to wherever I needed to go over sitting in a metal tube going 600mph through the air but the cost is the driving factor here.

>>2065849
>For triple the price.
Last time i took the train it was literally half the price of a flight. Sorry you live in the US where mass transit is specifically designed to be as Protestant as possible

>>2065241
They care, but it's of secondary or tertiary importance in most cases. The military is forced to hang onto their planes a lot longer than commercial aviation due to the vagaries of congressional funding instead of a steady income of ticket sales, so the opportunities for technology insertion are limited, and small percentage increases in performance won't pay off over the lifetime compared to commercial air where they're sortieing multiple times a day. A lot of time is spent working on obsolescence issues, replacing parts that stopped being made decades ago. The military does take big swings though, a lot of engine firsts happen there.
They swapped the old 4 blade canoe paddles on C-130H models to 8 blade NP2000 props and dropped the noise significantly. It also upped the performance so JATO bottles were no longer needed when working in polar conditions.

Anyhow I spent several years doing military jet engine procurement, so I can speak a bit from experience.

>>2065881
sorry you live in shitholistan that has regulated flight to be 3x what Americans pay for it

>>2065849

It's only that expensive because of globohomo

Dont interrupt when the men are talking, madam.

You are a techno-narrisist baby who has no idea how the world works. Your toxic optimism will kill us all. Living beyond your means cause pencil stroke and dreams were cheaper than reality on The Jetsons is no excuse.

>>2065480

Reality finally being met.

>>2065849
If you keep using it, they will keep subsidizing it....

>>2066015

This is how upside down u.s.ians minds are.....
