The EW-3000C completed successfully the 100 hours of continuous testing.

This motor marks the preliminary climax of China's development of aircraft piston engines. The motor is a water cooled 24-cylinder multi row radial engine. Blow-down exhaust turbines are fitted between the cylinder banks, and a geared centrifugal supercharger and a turbocharger is also fitted to the engine itself. Therefore this engine in not a "aspirated engine", but is a supercharged engine in turbo-compound construction.

...that's an extremely advanced engine...

Also, you call it an "inline radial engine." An engine can't be both inline and radial - they're mutually-exclusive.

My thoughts too. You beat me to it.

How you will call the following construction ..... 4 rows of 6-cylinder radial => in germany we call it "Reihensternmotor => "inline radial engine" (poor google translation)

By the way .... what about the HS-24K engine (http://www.jk-clan.de/index.php?page=Thr…4431#post134431) ?

Comparable engine .... other countries have them in serial production .... China is developing and testing this kind of engine (years behind) And now you say extremely advanced ????

Ah. I understand the point. A better term in English would be a "multi-row radial engine".

Ah, I see what you mean.

In English, that would just be referred to as a 'four-row radial'. An 'inline engine' would be something like a V-8, V-12, I-6 - something like that.

It is extremely advanced. Turbo-compound engines are very tricky to get right, and very few of the many historical designs actually worked to their full potential, even going into the mid-1950s. (Russia, for instance, never got a reliable turbo-compound into service before the turboprop engine replaced it.)

The French 'TRP Compose' has only been used for one production aircraft so far, starting in late 1944 - and it was developed to be bleeding edge by Hispano-Suiza (which is probably one of the top three aero-engine developers in the world), working with Turbomeca (which is probably one of the top three supercharger and turbocharger developers in the world), designed by an engineer who built one of the first working jet engines in the world, and all funded by the French air ministry's world-class R&D establishment. All that pedigree serves to stack the deck so I can claim such an advanced engine will work well enough for it to be used on a production aircraft, particularly with very regular maintenance.

So I stand by my statement that it is extremely advanced.

Now that I have a better understanding of what is being described, I have somewhat less concern about it. Yes, a turbo-compound engine is very advanced. Has China put enough effort into developing one? Perhaps. We do not know how much foreign assistance China may have received – from Japan (before the Chosen War), from the SAE, or by some intelligence coup from an unspecified source. So we cannot categorically say it is impossible. And nowhere has it been claimed that the engine is 100% reliable – the Chinese could be satisfied with its MTBF or MTBO, whereas another nation might find it a pile of scrap.

For better or worse China is a moderate WW industrial power and development of such an engine is plausible; to churn them out by the hundreds per month, no so much. Right now I would see the claim as referring to a trials or test engine, and the proof of the pudding would be to organize its production – with all the risk of loss of performance and reliability.

Yeah. It's not impossible - probably not even for China, since they already manufacture and even design many of their own aero-engines. But as I said, it is an extremely advanced development. In Wesworld, so far as I'm aware, only the US, France, and Britain have managed to put something comparable together.

I believe you are correct on the last point. Germany has not invested in the turbo-compound, with the turbo-prop being seen as a less expensive way to get the high horsepower. The Jumo 022 isn't there yet, but in the future it will.

This motor is still in testing phase ... no serial production yet !!! But i have to mention it, so the engine will not come out of nowhere.

30. April 1946
In a solemn ceremony, the german chancellor and the chinese minister for foreign affairs, Deng Hau Min, sign the Sino-German-cooperation agreement.
The agreement includes both, the purchase of 200 Krupp SGA and 500 Steyr Trosscarts. Additionally China gets the licenses for domestic manufacture of agricultural machinery- such as walk-behind and conventional wheeled tractors, combine harvesters, etc. The royalty payment per unit is 1,5% ad valorem of the unit price. Also the agreement contains the selling of heavy-duty excavators and other mining equipment from Germany to China.

Sure hope that those combine harvesters aren't the types you can bolt guns and metal plates on...

Sure hope that the Russians keep their military aviation knowledge well hidden from the Chinese.

And the Chinese thought that their German hosts were tight-lipped... wait until they get done dealing with the Russkiis... :D

Samara is "safe" and "visitor friendly" because a large chunk of the plant's current production is oriented towards the civilian market - chiefly the Il-12 medium airliner and sport planes. It's one of the few aircraft plants in the Russian Federation where you won't get automatically arrested for carrying a camera inside the front gates. Of course, because the Russians are a bit paranoid about security, they still have a force of MVD Internal Troops guarding the plant, and a group of senior FSB officers will sweep the plant beforehand to make sure it's 'clean'. And then, just to play games, the FSB officers will use a giant crane to put a giant tarpaulin over some random collection of boxes and crates, which will be declared off-limits to visitors and given an honor guard of thirty MVD troopers with submachine guns.

Visitors: "What is THAT?"
Tour Guide: "It's nothing! It's just a collection of boxes! Move along!"

;)

"visitor friendly"

I did not think that that phrase was in the Russian vocabulary... :rolleyes:

Sure it does. It's visitor-friendly when they say "Please come with us, comrade!" when they arrest you, rather than "I'm sorry, Comrade Colonel, the suspect was killed while resisting arrest."

I guess we can expect a lot of Il-12-like planes dropping paratroopers across the region in the near future... *starts production of the Mitsubishi jet*

Quoted

they say "Please come with us, comrade!" when they arrest you seconds before they shoot you in the back in a dark prison corridor, rather than "I'm sorry, Comrade Colonel, the suspect was killed while resisting arrest."

Corrected it for you there.
