What's new

Zhuhai Air Show 2014 - Updates & Discussions

No i meant that the basics of a jet engine design are 60 years old.

What do you mean for 60 years?

I don't think any country will still use a jet engine which was designed back in 60 years ago.

When your new jet engine has passed 10 years of safety flight record, this means it is becoming quite reliable and mature.

For example, neither the F135 nor even the F119 are as reliable as the F110, even though they are designed to be superior.
 
lool thats why i said even if the Chinese indeed suceed in finally building a reliable/tested one, then it wont be because of copying, since its simply impossible to copy a fighter jet engine.A fighter jet engine is not like other military systems which albeit difficult/complex, can still be copied. Engine is the most complex technology to master,. that is why i was also saying in another thread to some indian members on here, that there is no way a country will ever transfer you their engine tech NO MATTER HOW MUCH YOU PAY FOR IT. Its simply the crown jewel of any country/industry, so its guarded very secretly..:cheers:
Jet engine is not as difficult as you thought which human beings could make it 70 years ago.
Jet engines are supported by two legs: 1) Full range industries 2) $$$
China has them both.

It is hard to impossible for other nations, especially for those non-P5 nations, but not for China.
 
Of course no nation will hand over jet engine to anyone, jet engine is the heart for the jet to fly, without a mature reliable engine to power the aircraft, all the fancy 5th generation jet just become a paper airplane and will never take off from the runway. Every nation intend to build a fighter need to develop their core jet engine and not totally depend on import engine from other nation.

Indeed, that's why we are absolutely on our own for the development of J-20.

J-31 is not as crucial as J-20, so we are temporarily using the RD-93, but not for PLAAF's next gen backbone like J-20.
 
So I would like predict UK and Russia will quit this market soon.

It is hard to say right now.

For now, only the US has deployed the true 5th gen turbofan jet engine, while we have to see how long it will take China to deploy our WS-15, and how well the UK and Russia will do in the next decade.
 
Not exactly. They have had their templates but design was NEVER an issue. The Chinese can design a variable cycle engine today.. what they cannot do is come up with the materials to build it. Today's Chinese engines all suffer from that single limiter. To solve that the Chinese are taking the two pronged approach of try to replicate along with directed purchasing of information. Their idea is that if they can learn how to develop the alloys used on the PW-100 reliably.. they can take it further from there.

NO, you are wrong, the material is not question, China has been long exporting turbo engine blades for years to western countries, like US,UK, there are other reasons that China did not show its air engine productive abilities.

400km from China's shores? You must be kidding. China's defence target is at present 1000km from our shores. To break the anti-missile defence of carrier groups, there are combined means:
1, land based ballistic and hypersonic missiles (DF-21D and M20, etc)
2, air based supersonic and subsonic cruise missiles (CM-400AKG alike, YJ-12,YJ-83, YJ-63 ande etc)
3, sea based weapons: it may or may not contain CX-1 type of missiles.

There're no air defence system in the world that could shoot down China's ballistic and hypersonic missiles (DF-21D and M20, etc).
DF-21D can change mid-court during flight so it's very difficult to intercept and track. The way to destroy a DF-21D is locating its Missile Control Center and destroy it, otherwise it is helplessly just hoping that it misses the target. While AC is large, when moving can be difficult to pinpoint. This is why it is important that our thousands of merchant ships equipped with GPS locator can send the exact location of AC so we can accurately target it in addition to satellite tracking.

Anyhow that post is moronic. He undervalue our missile range and kept that stupid perception of our noisy submarine when the Yuan Class attack submarine is even more quieter than the Kilo-class submarine which are known as the "black hole" of the ocean.

This is an old news, now GE has also joined the party.

This time, it is for the gas turbine.
