>As conventional fuels were in extremely short supply by late 1944, Lippisch proposed that the P.13a be powered by coal. Initially, it was proposed that a wire-mesh basket holding coal be mounted behind a nose air intake, protruding slightly into the airflow and ignited by a gas burner. Following wind-tunnel testing of the ramjet and the coal basket, modifications were incorporated to provide more efficient combustion.

>The coal was to take the form of small granules instead of irregular lumps, to produce a controlled and even burn, and the basket was altered to a mesh drum revolving on a vertical axis at 60 rpm. A jet of flame from tanks of bottled gas would fire into the basket once the P.13a had reached operating speed (above 320 km/h), whether by using a rocket to assist takeoff or by being towed.

>The air passing through the ramjet would take the fumes from the burning coal towards the rear where they would mix under high pressure with clean air taken from a separate intake. The resulting mixture of gas would then be directed out through a rear nozzle to provide thrust. A burner and drum were built and tested successfully in Vienna by the design team before the end of the war.

why weren't there any coal powered jet planes if it's possible to make such an engine? or maybe they were made but i don't know about them

not as warbirds ofc (this one was supposed to be a fighter) but as transport or sport aircraft
>>
>Ramjet

Just take a look what it is or how it works... sums up why nobody really made em
Germany in the otherhand probably would've made if they had time/resource

>>34672779
the best coal has slightly less energy density than jet fuel, but barely over half the specific energy of jet fuel.

It isn't efficient at all. Why use coal when oil is perfectly fine?

That thing was both unbelievably retarded and unbelievably brilliant at the same goddamn time. The engine design was full fucking retarded, but worked. The fuselage and airfoil configuration was completely idiotic but incredibly stable, even in the transonic region.

I have no doubt that this would have gone on to be produced out of sheer desperation and kicked way more ass than something this fucking stupid has any right to had the war gone on to '46.

Imagine in some alternate reality there is a world where coal-powered planes are a thing and the cold war contained some examples of them in the Chinese / African armies. Plus some sort of coal powered concord.

What >>34673441 said.

On of many reasons Germany invaded Russia in 1941 is because Southern Russia had (and still has) oil fields.

Germany also invested a lot of time into synthetic fuels research during the war.

One natural resource they did have in abundance was lignite.
>>
>>34673422
yeah, but it's cheaper and somebody could want to experiment with that engine

it's a pity nobody tried to build such a plane post-war

Why the fuck isn't there a good 1946/Conceptual Cold War game?

Why can't I be a tanker in the Fula Gap, removing American forces as nuclear fire bleaches everything red? Why can't I be a Mosquito pilot, running for my life as I'm pursued by a coal-powered ramjet interceptor?

Either of these settings would be great, why is there nothing?

not sure if kerosene is cheaper than the specially prepared coal if we had a large scale facilities to prepare coal for jet engines but at the very end somebody might build a flying experimental/novelty aircraft liek that, grr

also b-25 is a frontline bomber, you mean b-24 like those used in the failed tidal wave operation

yes, there still exist wood powered trucks in the north korea

but those are mere cars

if north korea was ingenious they could make a 3rd-4th generation coal powered fighter jet/

So here's a tip; if you're going to write about a prototype aircraft in combat, it makes a lot more sense to establish a hypothetical scenario to accommodate that rather than shoehorning the aircraft into already written history. There's a reason you don't see lasers in novels about World War II that take place in 1943.

Also fuck you.

Doesn't North Korea still have T-34s?
>>
>>34681475
I doubt it. We turned most, if not all of them into scrap metal by the time the Korean War ended, and by then they were important enough, along with China, to be getting better Soviet tech than surplus WWII vintage tanks. The Soviets wanted to remain influential on the peninsula, so arming the Norks with shitter T-34s would have been a bad idea. That being said, if any survived you can bet they're still in active use... you know, when they have fuel for them.

aww, cute!

A nation under oil embargo in an alternate timeline where air power was taken very seriously (as opposed to ours where it was seen as a novelty or full of bullshit theories that persisted for decades) might very well make something like this and use it with great effect in a defensive context.

>>34673422
While it has less specific energy what you need to remember is that with subsonic and transonic aircraft there's this threshold of "good enough" that's easily met. I say that because air combat of both WWI and WWII was actually quite forgiving as far as technology was concerned, "obsolete" was more or less a mild handicap if the performance gap wasn't absurdly big. (Sopwith Camel versus Fw-190) Even early war aircraft developed during the 30's were still able to hold their own with aircraft entering service in 1945, and even the early jets with their cutting edge technology were still vulnerable to some jackass in a Curtiss Hawk or it's derivatives.

During the later years when jets started really getting fast the obsolete fighters still could piss in your cereal, and when air-to-air missiles came about the old jets still found their use in air forces. They didn't even have to do their original thing, F-86s were first flown in 1947 and only retired in 1994 in Bolivian service, their last conflict was in the Indo-Pakistani War (1971) and managed to score kills against more modern designs flown by the IAF. A more modern example is the F-16, it really isn't the best aircraft out there but it does a lot of stuff and it does them all "good enough" and continues to do so cheaply enough, upgrades continue to prove it's effectiveness. There's other examples all throughout history just like it too.

So again, the bar of "is it good enough?" is really all that needs to be met. Being able to fly planes that do the job is more important than being able to field the best planes for the job.

meantime some dudes try to design a synthetic fuel for convenient jet engines, made from coal

https://www.technologyreview.com/s/417217/cleaner-jet-fuel-from-coal/

not that cool as a real coal engine though

>>34681715
i believe that only late war superprops could compete with jets having a comparable climb and while being slower the early jets needed time to build speed. for a kittyhawk jets would be uncatcheable and only killable if they make some grave mistake

for the same reason biplanes died out early-mid war

I've read quite a bit about the flying dorito, aerodynamically it was incredible for its time. The engine was a rather good idea but born of need.

I'm skeptical of the ramjet producing enough thrust for take off, especially with the airfields Germany had left late war, but if this thing could get up to speed with some rocket boosters itd likely be able to go a bit over the sound barrier.
