*New J-10 Thread*

[Deino]

O.k, then back to the topic ! ... here's an interesting picture posted by "planeman" in the Google Earth tread

Jiugucheng Airbase 37°29'N 116°06'E has an assortment of J-10, J-7 and JJ-6 aircraft. The 'washed out' image makes identification difficult but the canard foreplanes of the J-10s can be seen.

Hmmm ... my first idea was: "Great" maybe this is the second service regiment ... but after looking at several sources I didn't find a Jiugucheng Airbase within the Jinan Military Region ... nor with Scamble or Rick's page !

Any idea what regiment / division could be stationed there or is it another test facility ???

Thanks in advance, Deino

During the 1991 Gulf War the F-15 was the only airplane, USAF or otherwise that was cleared for BVR intercepts. This was because only the Eagle had the necessary hostile IFF hardware that could identify targets that did not respond to a friendly IFF query. Not even the F-14 had such a capability. This was a requirement, if they wanted to avoid fratricide.

That's Why I mentioned the Eagle Mafia. The Air Force was run by Eagle Mafias.

This situation, however, is little changed today. It would be highly unlikely that the F-16C or F-18C would be cleared for BVR intercepts in a future conflict.

Vipers have scored BVR kills in conflicts since GWI.

If the J-XX is really intended to supercede the Su-27, then it will be designed as primarily an air-to-air platform with a secondary air-to-ground capability. This is not unlike the F-22, which has only a token air-to-ground role.

Nobody makes single role fighters any more. The F-22 was conceived before the end of the Cold War. We are talking about ancient history here in terms of geopolitics. If the US can't afford to do it, I don't think China has that kind of cash to throw around either.

Here is a new article on J-10. It says that 100 J-10's have been produced, and that they are transitioning to the WS-10A, which has finished development. The designers are concerned about how compatible the existing design is to the WS-10A in terms of the lift generated at different engine output levels, the mechanical and electronic integration of the engine into the body and how the different air flow patterns will affect performance specs.

(It also says some unimportant things about how J-10 has been continously refined since its early days as a Lavi based design and how its specifications were constrained by the AL-31F engine.)

　　经过10余年的考验歼十飞机于2003定型生产，从歼十早期图片可以看出歼十飞机经过10余年究竟有多大改变，其中有试飞员牺牲，两机相撞的磨难，96年试飞10年不断的改进，不断的试飞，不断的修改飞机设计，于年初达到产量100架，从进口的发动机数量来看250台al31f未来产出的歼十150余架，其余发动机用于备用，从进口发动机数量来看歼十飞机已经步向成熟。

　　歼十飞机的气动是近距耦合鸭翼三角无尾布局，歼十飞机气动布局，克服了以色列狮是飞机近耦合布局，机翼重力配比不协调的问题，以色列的狮式飞机就是鸭翼与飞机机翼升力配比失调，而失败的，歼十飞机在不断改进试飞的情况下，很好的解决了这一问题。鸭翼与机翼升力配比与发动机的推力也有关系，发动机在不同推力的情况鸭翼与机翼的升力都有不同，这也就是以色列狮式飞机第二个问题发动机推力与机翼升力问题。正因为上述两种原因狮式飞机被迫下马。
　　
　　也就是因为上述两种原因狮式下马，技术成果转让给中国，601在一种技术上有缺陷的飞机，结合歼九和我国最新的飞机研制成果，研制而成歼十飞机。
　　
　　这里主要讲歼十飞机的发动机与歼十飞机的整体性能，前面介绍过狮式飞机研制失败的两个诱因，歼十飞机的两个软肋就是在这两点上，al31f发动机装进歼十飞机中，减小发动的体积，增大飞机进气口，改变了歼十飞机气动布局，al31f在歼十飞机上是成功的，也就是说al31f发动机在歼十飞机上已经克服了第二种诱因，而第一种诱因与第二种直接相关，虽然歼十飞机的设计上克服了狮式飞机的第一种诱因，但是介绍歼十飞机文章没有介绍过第二种诱因的改进完善问题，而狮式飞机的研制最主要的难题是发动机在不同推力上与机翼升力的问题。
　　
　　太行发动机的研制成功，在心喜之后带来的问题是1ws10a发动机能否克服第二个诱因2在太行发动机不太成熟的情况下，装入歼十飞机内部改变内部系统结构能否成功3改装发动机给飞机带来的气动等改动会不会影响飞机性能。
　　
　　对于成熟的飞机来讲换发等同于从新设计飞机内部结构，换发初期飞机性能会极不稳定，飞机需要重新试飞，歼十飞机能不能挺过这一关是我国歼击机国产化的重要一关。

huitong claims that this is CCTV7 showing the 44th division of J-10, but I'm not sure since all we see is a guy climbing in.

 

[bd popeye]

He's not going to fly that airplane. He does not have on all his flight gear. I mean where's his G-suit?.Those gloves are too bulky....He may just be a pilot doing some ground checks.

 

[crobato]

These are J-10s alright. Note the antenna on the canopy.

Hey, can you clarify a little bit? What does the antenna do exactly?

 

[chicket9]

Of course that guy is not going for a flight. And such 'acting' is quite frequent when media is around the military...eg i watched a thing on naval SEALS and they were standing up in broad day light without full gear on in the middle of a beach...that aint gonna happen in real life.

Anyway, besides the helmet, perhaps he is not in full gear...but aren't PLAAF pilots known for that? I mean, I've seen pilots of the PLAAF only wear a leather jacket, life jacket and helmet with breathing apparatus. No green suited overall type. I mean we should be fortunate this pilot wears an overall blue suit, looks way better than leather jacket and green trousers.

But if indeed this guy is not going on a flight and therefore is not wearing his full gear, it would at least decieve 99% of the Chinese population (and most of the world too)...coz MOST people in this world are not as militarily enthusiastic as people on this forum, and when they see a guy in a helmet climbing on a plane, they'd believe it.

Look at the raised canopy on the back of the pilot. Note the strip that runs on top of it. That's a communications antenna. All J-10s have this, and the same system is used and present on the FC-1 prototypes. You can check for any number of J-10 pictures that are close and clear enough to see the canopy and you will see this antenna.
