*New J-10 Thread*

Gollevainen said:

To Crobato:

The "Seccond generation" in common western practice is the "starfighter generation" which covered the first radar/AAM supersonic fighters like the MiG-21, Mirage III, F-104 Starfighter and J35 Draken. Third generation is described as the "phantom generation" which was clearly the next step from these (but not as big step as the on between third and fourth). Planes included to the third generation are F-4 Phantom, Mirage F1, MiG-23 and J37 Viggen and ofcourse J8II.

The differences between various generations cannot to be determine just blindly focusing on some design features without thier context. For example Mirage III and Mirage F1 features alot of similar aerodynamical features and even the same genration engine but are still considered to belong to different generation. Draken had 1st gen. Engine (Avon from Hunters) but was still the best 2nd generation fighter ever existed.

Altough J8II may be one of the lesser third generation planes, it still is a third generation and there is clear and logical step in chinese aviation industry when it moveed from direct copies to somewhat indegenious design. All factors favours that J-8 and J-7 belongs to different generation.

核心提示：宋文骢院士指出，鸭式布局是我们和国外同步研究的，歼10的外形和气动布局完全是我们自己搞出来的。其实，熟知中国航空史的人都知道我们有过一款夭折的战机——歼9，它是世界上首批采用鸭式布局的战机之一。所以认为歼10是“狮”仿制品的说法是多么的可笑和浅薄。 a]?}~YJy

　　1986年，56岁的宋文骢被国防科工委任命为国家重点型号飞机总设计师，此后的20多年，他为了我国新型歼击机的研制殚精竭虑，呕心沥血。在他四十多年的航空生涯中，总是不畏艰难，大胆创新，努力抢占航空科技发展的制高点，以满腔的报国热情，施展着航空建设的蓝图，让战斗之鹰在蓝天中展翅翱翔。 r5*A])QN

　　记者：我们知道，您担任了多款新型飞机的设计总师，当您亲自严格把关设计生产的飞机在蓝天中翱翔的时候，您心里是什么样的感觉呢？ nS)3

　　宋文骢：歼-7某改进型、新型飞机两次首飞时，我的心情是不同的。歼-7某改进型首飞时，我的心情非常紧张，担心起落架或什么地方会出现问题，两眼紧紧盯着飞机不敢移动。新型飞机首飞的时候，心情非常激动但并不紧张。按理说新型飞机采用了新布局、新系统、新成品、新技术等等，难度大得多，但因为我知道我们的方案时先进的，设计是严密的，技术是过硬的，元器件、子系统都进行了自上而下的综合，进行了反复的地面试验。 >HSpf,QF

　　宋文骢：鸭式布局是我们和国外同步开始研究地，当年搞歼-9型战机无水平尾翼方案的时候，我们就提出了鸭式无尾布局。60年代，美国开始研究利用脱体涡来增加飞机升力。我们在歼-9战机上进行了试验。为了新型战斗机的布局方案，我们做了很多试验，在确定方案前，风洞就吹了上万次。我国新型战机的外形设计和气动布局完全是我们自己搞出来的，没有借助国外的力量，这一点我觉得很骄傲，很自豪。 GC_0~HSE

　　宋文聪：是，我觉得一个庞大的工程不仅要关注整体，更要注意解决每一个局部的关键技术问题。作为总设计师，我也要考虑地更深远些。可能有些人会认为一些模具和零件要报废，要花费更多的时间和精力，但我们作为飞机的设计者，必须每时每刻都打硬战，我们交出的必须是一个完整的没有质疑的答案，这样才算完成了自己的责任。


歼-10实际重量比原设计目标重量减轻２６公斤

歼十飞机是我国自行研制，具备当今世界先进水平的新一代、高性能、全天候战斗机。随着歼十飞机的研制定型和装备部队，我国形成了一整套具有自主知识产权的第三代战斗机设计技术。而实现这一关键突破的就是歼十飞机总设计师、中国工程院院士宋文骢。 $yX"
　　宋文骢先后参与了歼七、歼八、歼十等多个飞机型号研制，是我国惟一担任过两代国家重点型号飞机研制并走完全程的总设计师。他先后主持和参与研制改进我国轻型全天候中、高空高速歼击机和轻小型全天候战斗机。 wuOKLrP

　　先进的气动布局是自主发展先进战斗机的基础。歼十飞机研制初期，宋文骢就清醒地意识到新机研制必须充分应用当前国际航空领域的先进技术，他提出必须攻克一系列重大关键技术。他带领气动专业的设计人员投入模型生产、风洞试验、数据分析、布局改进等繁重的设计试验，转战南北，进行了上万次试验，采集并处理上百万个气动数据。几个月后，在新歼方案论证会上，宋文骢从战术技术要求到飞机的使命性能、系统结构、武器火控等讲起，４小时的报告赢得满场喝彩，我国新一代歼击机有了雏形。 LLr K

　　歼十飞机起点高，技术新，跨度大，然而研制初期却技术基础薄弱。作为设计工作的组织者、指挥者和重大技术问题决定者，宋文骢从方案设计到结构材料，从技术标准到专业设置，从工艺生产到成品研制处处都以创新为根本，采用集总体、气动、飞控为一体的综合/优化设计方法，走出了一条自主创新之路。 k~{qSJ

Jan. 5 (Bloomberg) -- China Aviation Industry Corp. I, the
country's biggest aircraft maker, unveiled the Jian-10, a fighter
jet developed completely using proprietary technology.
The state-owned company, also known as AVIC I, and the
domestic defense industry developed the fighter, its Taihang
engine and a new generation of guided missiles, the
company's deputy general manager Geng Ruguang said at a press
briefing in Beijing, where a demonstration video was shown.
``The Jian-10 uses a lot of new technology and materials,''
Geng said. ``China is the world's fourth country with the
capability to develop its own advanced fighter aircraft, engine
and guided missiles, closing the gap with advanced nations.''
Geng didn't say how much the fighter cost to develop or how
much it would sell for. China's airforce has been equipped with
the new air-to-air missiles, he said.

China unveils indigenous fighter jet

By Benjamin Kang LimSat Jan 6, 4:24 AM ET

China has unveiled its Jian-10 multi-role indigenous fighter jet, marking a "historic leap forward" and narrowing a technological gap with major military powers, state media said on Saturday.

China is the fourth country in the world capable of developing its own advanced fighter aircraft, engines and air-to-air missiles, the People's Daily, the mouthpiece of the Communist Party, said in a front page story.

The newspaper did not identify the three other countries, but defense analysts said it was apparently referring to the United States, Russia and France.

"The Jian-10 is superior to the SU-27 but inferior to the SU-30," a military source who spoke on condition of anonymity told Reuters, referring to Russia's Sukhoi fighter jets.

A five-minute video was shown to Chinese reporters in Beijing on Friday, revealing how the fighter takes off, lands, fires missiles and flies in formation, the official Xinhua news agency said. Foreign journalists were barred from the news conference.

The Beijing Daily, the Guangming Daily, the Farmers' Daily and Internet portals splashed pictures of fighters taking off and pilots marching past a row of fighters.

"It has increasingly become apparent the J-10 has the potential of becoming one of the most significant fighters in the next few decades,"

said on its Web site.

But Xinhua quoted unnamed military experts as saying the Jian-10 cannot match the performance of fourth-generation U.S. fighter jets, but its basic design and indigenous equipment are comparable to those of mainstream fighter aircraft in the West.

As many as 300 Jian-10 may be produced, sinodefence.com said.

The Jian-10 first flew in 1998 and entered the PLA Air Force service in 2003, sinodefence.com said, adding that the single-seat and twin-seat trainer are "all-weather, high-performance multi-role fighter aircraft capable of both air-to-air and air-to-ground roles."

"(It) marks a breakthrough in China's research and development of heavy fighter aircraft," Liu Gaozhuo, executive commander in chief of the Jian-10 program, told Xinhua.

According to China's defense policy paper released last December, the air force is reducing the number of combat aircraft, giving priority to the development of new fighters as well as air and missile defense weapons.

The China Aviation Industry Corp. I, China's leading aircraft manufacturer, provided the armed forces with 90 percent of its airborne weapons.

AVIC I has produced 15,000 aircraft, 50,000 aero-engines and more than 10,000 missiles. Company sales rose for the sixth straight year last year, hitting 80 billion yuan ($10.3 billion), up 15.7 percent. Profits surged 42 percent to 3 billion yuan.

China has claimed Taiwan as its own since their split in 1949 amid civil war and vowed to attack the self-ruled democratic island if it formally declares independence.

The United States and Japan are to discuss in February joint plans for their troops to deal with a potential stand-off between China and Taiwan, Japanese media said.
