This is coming from a man who was constantly provoking me with his rudeness. ))) And as soon as he received the same coin in return, he immediately started talking about my hostility.Again with the hostile response. Calm it down. You get defensive whenever anyone questions what you say, you don't provide what you expect others to do and you call everyone names when they counter your points or call them out. Play nice.
Nope! Nope! Nope! Read the definitive work on the P-47, Warren Bodie's extensively researched book, "Thunderbolt!" It was based on the P-43 which was based on the P-35 which was based on Seversky's two seat sportplane. After the P-43 showed promise Republic abandoned its initial P-47 concept, a lightweight fighter using a V-1710 and enlarged the P-43 with the same arrangement but a R-2800 instead of a R-1830, to make the P-47. FACTS!It is a totally new independent design, having V-1710 at the initial design stage.
I guess it depends on what "enlarged with the same arrangement" meansNope! Nope! Nope! Read the definitive work on the P-47, Warren Bodie's extensively researched book, "Thunderbolt!"

The problem with the Germans was that while they sank money and resources into advanced projects like rockets and jets and missiles and cool stuff that everyone believes meant they were more advanced than everyone else, we forget that the Germans didn't get some of the basics right. Had they concentrated on these, perhaps they might have been able to have lasted longer - of course it is to our benefit that they didn't.
They never got a 2,000 hp plus engine into production and service, their advanced four engined heavy bomber programme Bomber A was a failure, resulting in one of the worst aircraft of the war, the He 177, their replacement fast bomber programme Bomber B was also a failure because they couldn't get their 2,000 hp plus engine to work, which meant that aircraft of pre-war vintage were kept on in service for far longer than they should have been. The He 111 was still in the Luftwaffe's frontline in 1945, equating to the RAF relying on the AW Whitley, or the USAAF relying on the B-18 Bolo in that time.
The Me 262 and He 162 were highlights, but were troubled because of their unreliable engines and the reliance on forced labour for their manufacture.
The cost of the way in which the Third Reich was run was directly responsible for Germany's failures. The fostering of internal squabbling, currying favour, self-promotion and outright sabotage of competitors' plans was no way to run things during a war footing, but that's how they did it.
Must say this is the first time i ever read of poor compressor blades. Would be nice to add some official figures and quotes.Rubbish. The compressor blades were made of poor quality metals and flame outs caused by the engines shedding fan blades or blades disintegrating is widely recorded.
...they did have a foot in the past. The Riedel starter motor was one of these. Relying and small piston engines with their own fuel supply for starting means the engines cannot be started in the air and it seems like a bit of a waste of weight. Surely an electric or even cartridge starter, like the British engines would have been a better option. The Riedel was started by a ring pull starter that was done by guys on the ground standing in front of the engines, the rung protruded out of the bullet and had to be pulled to engage the starter for each engine.
Another peculiarity was the fuel management of these engines. Thrust and fuel flow was managed manually by the pilot based on instrument readings, which meant the pilot had to keep a keen eye on fuel flow and engine temp gauges to move the power levers and the zwiebel, the variable thrust cone located in the exhaust nozzle, which was driven mechanically by a long shaft that extended aft to the thrust chamber. By 1945 this was relatively simplistic because there were already mechanical and electric fuel control devices fitted to piston engined aircraft, not to mention constant speed propellers, which equated to varying thrust output, rather than controlling the zwiebel, whose operation should have been automatic and keyed into the fuel control system, rather than manually actuated by the pilot.
Just one small addition.
Even today, it is a rule not to buy a car that is a new model for the first few years until the "childhood diseases" of a complicated technological system are sorted out.
And jet engines were also new as a technology (in serial production). We can argue whether the German engines worked for 20 or 25 hours, but the Allied side also had initial problems. The P-80 did not fly on engines that were good for 200 hours of operation - in fact, the first XP-80 ate itself and the tests in England were stopped because one crashed (due to the engine) and not to mention the death of R.Bong. So ....

Ok, this is like a comment by someone that totally missed the starter buttons inside the cockpit. The riedel could be fired-up from the cockpit, it wasn't done on the ground to not overload the batteries,
Love this part, comparing apples to patotoes (not even oranges).
Yes, and no. I'm not sure a 2000 hp engine, per se, would have been that necessary.
As for the jets, yes it was very early days for jet propulsion and they suffered from all kinds of problems. However, I'd also argue that jets represented one of the few ways that could have allowed the LW to face the onslaught of Allied air power from say late 1943 onwards. Incrementally better piston engine aircraft weren't going to cut it anymore.
This is, generally, how dictatorships work. The strongman at the top stays at the top by playing the various factions against each other and have them compete in bootlicking. It's inherent in how the entire system works. Nazism, fascism, communism, it's all the same.
Democracies may seem weak and impotent, endlessly debating things in public. But once they decide to act, they are immensely powerful.
There might be a lesson here for the modern world as well..
Modern and powerful jet engines are indeed expensive. But more expensive than the piston engines of the similar power - I don't think so.Here's an article that made the rounds recently about why jet engines are expensive.
Sometimes, it depends a lot on the path taken. One path might offer the savings of both the material, coin and time vs. another path.The author is not an authoritative source on jet engines, but still, it's a decent enough overview. In particular it has some nice graphs nicked from a paywalled article describing TBO, specific fuel consumption, etc. as a function of time. And it shows a somewhat smooth and steady rate of improvement, with no evident low-hanging fruits. Or to put it another way, every advance was the result of a lot of $$$, blood, and sweat. So perhaps we shouldn't assume that the Germans, or anyone else for that matter, could have made dramatic advancements in time to make an impact during WWII. Biggest advancement is perhaps recognizing the potential earlier and start funding R&D at a higher level sooner?
I must have missed this earlier.Ok, this is like a comment by someone that totally missed the starter buttons inside the cockpit. The riedel could be fired-up from the cockpit, it wasn't done on the ground to not overload the batteries, just like the BWM801 were started with an APU and the Db's by cranks (or apu's) for the same reason.... The riedel was actually a very good idea as the 004's spool time at start sequence was high, meaning it needed to run for a long time before combustion was able to run the 004 by it's own power. An electric starter would burn out
