Why haven’t they outlawed propeller airplanes yet? Isn’t this inferior technology? Is it even safe? I literally cancelled one of my flights when I found out it was on a Dash Q400.

Now imagine this including piston, rotary, ultra high bypass, propfans and experimental methods of propulsion.
>>
>>1645122
And props have better low altitude performance and better throttle response.
>>
>>1645122
Wow imagine that wind power doesn’t work well beyond supersonic, you got me, send all propellers to the crusher
>>
Props 4 lyfe

>>1645248
I saw a comment about how certain trips are shorter with props due to faster take off and landing.

>>1645278
It does.

>>1645043
less fast != inferior
Propeller planes tend to be more efficient but be aware that there are several types of said propeller engines (piston engines, turboprops, even some wankel engines) each with their own pros and cons.
The current commercial aviation market prioritizes fuel efficiency since fuel isn't cheap and also green energy shit so propeller planes will likely be here to stay.
In addition to this propellers are in some cases shorter then their jet counter parts because to operate efficiently a jet must reach high altitudes making short flights the worst. This means props may have a longer lifespan as their fuselage expands/compresses less during flights.
They can be both safer and less safe at the same time. on one hand a sudden depressurization (if the cabin is even pressurized on a prop plane) is much less severe but on the other you have less time to brace yourself if a crash is imminent but that's just what i determine with my doofus monke brain people
>>
>>1645043
propellers are the most efficient, simplest, cheapest and most reliable technology for short distance low speed flights
>>
>>1645043
Jets are inefficient trash, the only good thing is that they work at very high altitude so the plane gets efficiency from the thinner air
>>
I don't see how jet engines could be electrified so props might even outlive them.
>>
>>1645057
Those propellers are fucking big

>Why haven’t they outlawed propeller airplanes yet?
Why should they?
>Isn’t this inferior technology?
Not at all, it's superior in some aspects.
>Is it even safe?
Certainly, propellers aren't exactly known to blow up midflight.
>I literally cancelled one of my flights when I found out it was on a Dash Q400.
Why?
It's not a Boeing after all...

That's a submarine propeller

complete argument disregarded
for real though, i know they have veeeery specific use cases but you might as well get there on a helicopter

not based at all... you disappoint me anon

Nah it's not pixelated enough. It must be from a plane.
>>
>>1645043
Troll thread but jet engines have propellers too, they're just inside a duct. The Q400 is also a turboprop so it's pretty close to a jet.

no, especially since turboprops exists

safer than driving

>>1646224
If we're talking GA, then a piston engine aircraft is far simpler than a helicopter. 100x easier to fly, too.
>>

>clussssshhhhhter bee dissshhhhhordered sssshhhhhubhhhumansssshhhhh

>>1646224
most roflcopters are painfully slow and expensive is the problem. Cant carry too many people/stuff and the range is kinda crap. A turboprop is pretty much the endgame of propellors as they're effecient, fast, loud and can be attached to anything.
>>
>>1645852
Some are faster than turbofans on average, depends on the trip and model.

>>1645875
And most underdeveloped. And the rest is very underdeveloped too.

>>1645888
I think those props they use on military carriers in Europe and Russia is better than jets for that use case:
>>1645945
(which uses a garbage engine due to ZOG)
Some of them are very different from usual turboprops.

>>1645910
EDFs are somewhat close to them.

>>1646335
I never understood how that dildo enclosure works, turboprops with many blades, EDFs and propfans don't have them.

>>1646565
And simpler, faster and safer than a piston helicopter. But I think GA tends to be very safe if you aren't retarded or got someone triggered.

>>1646590
They (and you) do it all the time.

>>1646609
And probably run on a lot of fuels, if it pleases the crown...

I think a lot of the hatred of aircraft and flying comes from a deep seated fear of being in the air.
Propellers are an obvious target because they act as an exposed mechanism, which reminds people of the realities of aviation. That they are in a machine in the sky.

contrary to what most boomers think, yes, you are correct: you can run a turbine on just about anything, as those fuckers run nuclear hot.
>>
On variable pitch propellers, in what manner do the blades' pitch actually adjust? On what axis?

The propeller changes it’s angle of incidence relative to the propeller hub’s rotational axis.

I don't know if you can get something like this without petrol:

https://en.wikipedia.org/wiki/Liquefied_petroleum_gas

LNG and CNG are very problematic and those things are liquified with very low effort.

>>1647206
And it sometimes has reverse.
>>
>>1647330
they can run on natural gas no problem, no requirement for it to even be liquefied
reverse is just another position of the blade angle
>>
>>1647355
LPG isn't methane. Those gasses need to be compressed or liquefied because they occupy too much volume.
Other gasses can be easily squeezed into a metal canister but it's very hard to do the same for natural gas. A mixture of both is also easy to store:

https://coecs.ou.edu/Richard.G.Mallinson/PDFs/97AIChEJ1108Horstkamp.pdf

Adsorbed natural gas is another option, it uses a porous material to trap gas into a small volume.
>>
>>1647330
I found something:

Renewable and tuneable bio-LPG blends derived from amino acids
