矢量航发版歼10B将在珠海航展表演 精彩程度不输苏35
矢量航发版歼10B将在珠海航展表演 精彩程度不输苏35

上回写航展前瞻的时候，尽管有很多人在留言里表示“没意思，不想去了”，但还是有一些读者朋友，通过我发的那张F-16 MATV以及图注猜出了些什么。
今天，它如约而至。距离2008年歼-10首次在珠海航展上公开展示，正好10年。这样，起码在大部分吃瓜群众心目中，这次航展也是有、意思了
挂着仨副油箱转场过来，还有一对发烟装置，后机身上防尾旋伞支架的安装基座也留着
猛盯菊花！我歼10矢量推进验证机发动机喷管详解1/12

近日歼10矢量推进验证机亮相珠海，有网友就对发动机喷管的不少细节进行了分析。歼10的调节片末端可能也采用了类似F135发动机的薄壁和折边结构，在减轻重量和运动惯量同时增加强度抑制振动。（来源：探索月球 航空新视野-赤卫 垂直风行 JacKsonbobo）
首次公开亮相的歼-10B-TVC（姑且这么称呼），涂装上最大的变化是将其垂尾上“1034”编号（10代表歼10系列飞机；3代表第三个型号——1代表10、2代表10S、3自然代表10B；4代表第4架原型机）原本使用的红色字体（试飞院的战术飞机编号多用红色），改为了类似我军现役战机使用的黄色字体。
早在歼-10B还处于试飞阶段时（2013年初），其原型机也曾涂上过相同颜色字体的编号，对比可见该机和歼-10B-TVC的区别
根据官方预告，在此次航展上，我军现役的歼-10B将继续参加静态展示。这样一来，歼-10B-TVC的这种“准现役涂装”，还能给人一种TVC技术在我军实用化指日可待的感觉
不过验证机毕竟是验证机，要说它能否推动歼-10的外贸工作可不好预计。毕竟除了俄罗斯外售的苏-30MKI系列飞机对应的客户之外，目前对TVC这种技术真正感兴趣的买家并不多。
很多用户买了苏-30MKI系，也并非就是对AL-31FP有多大瘾头，更多看中的是其相控阵雷达——谁叫苏-30MKK这方面慢了一步呢
然而正如历届航展所体现的那样，本届珠海航展也要承担中国空军和航空工业对外开放的一部分职能。除了展示歼-10的优良气动设计和先进飞控技术之外，歼-10B-TVC的飞行展示，对于第二次独立参展的航发集团来说，也是展示仍然在业内外有所争议的中国航发工业技术实力的重要机会。
事情总是向好发展的，使用国产发动机的歼-20也将不仅仅是停留在原型机而已
说回这个歼-10B-TVC，根据一位曾在试飞院目睹歼-10TVC试飞场面的大佬透露啊，“看它扭屁股，忘了苏三五”，人家毕竟眼见为实，那就算他话糙理不糙好了
这本事是咋实现的呢？
尽管在手册上，歼-10的可用迎角的确不算大，但在去年分析国产矢量推力发动机的时候我提到过，在歼-10定型试飞阶段（1998-2003年），受限于当时客观条件，其大迎角飞行性能本就未被完全发掘出来。
对于采用放宽静安定度布局，敏捷性出色的歼-10系列飞机来说，完全具备完成“眼镜蛇”机动的前置条件——低速下，其主翼能提供足够的抬头力矩，让飞机迅速抬起头来；主动差动控制的鸭翼，可以保持左右两侧涡流的对称性，防止飞机在这一过程中偏航；尽管并非苏-27那样的双垂尾布局，但其高大的单垂尾+双腹鳍仍能保持较好的大迎角下的偏航稳定性。。。。。。
歼-10的主翼没有延伸边条，省却了侧卫系飞机大迎角下因边条作用导致涡流不对称的烦恼
但接下来的动作就少不了发动机帮忙了：虽然采用大面积三角翼的歼-10，在迎面气流的作用下，理论上具备良好的低头特性；但由于其面积较大的鸭翼和主翼的位置关系问题，此时附加的抬头力矩会使得低头时间偏长；此时矢量推力发动机提供的直接低头力矩，有助于让飞机尽快平稳渡过低头阶段。
当然啦，玩这一出的时候发动机还得有绝赞的抗喘振性能，不能玩着玩着就熄火了，从之前在本场的表现来看，606所显然对“太行”的防喘能力做了改进
另外，三轴TVC还可以在提供低头力矩的同时，抵消可能出现的偏航力矩。。。。。。但个人觉得，歼-10这种具备一定主动控制能力的飞机，更多考虑的，应该是如何利用偏航力矩玩出更多的花活来。
以苏-35为例既然机头都回正了，何不把低速下的机头指向做到极致？落叶飘走起！
就算机头还在上仰，此时施加一个偏航力矩，借助歼-10良好的抬头特性，抛饼走起！
所以啊，歼-10B-TVC翼下悬挂的两个深蓝色发烟设备（这颜色，显然是从八一飞行表演队顺过来的）的用意就很明显了。
说到F-16C与AH-64D编队通场，很多人想到的是新加坡航展上该国空军的日常表演。但荷兰空军也有类似项目，展示前者出色的低速大迎角性能，注意F-16翼尖的拉烟设备
除了能更好勾勒出歼-10表演的姿态之外，想想俩吊舱在气动和重量上也等于挂俩格斗弹了，这还能给人一种贼实战的感觉有木有！虽然改装矢量发动机之后增重难免，但既然是航展表演，
歼-10B-TVC完全可以通过减少载油量的方式保持“身轻如燕”，献上一场效果不输于苏-35的视觉体验。
一花开放不是春。早在歼-10B-TVC抵达珠海之前，多架歼-20已经转场前往南部战区空军某场站。尽管静态展示嘛。。。。。。那是肯定不会有的，但动态展示的规模，那也是肯定比上届强大的。
两年来，随着歼-20先后交付多支部队，在曝光率逐渐增加的同时，积累了一定的装备规模
说到这个规模啊，在去年7月30日沙场大阅兵前后，官方发布的受阅歼-20编队座舱视角中，就有人看出，首装歼-20的空军试训基地某部在彩排中曾以五机编队展示，一如歼-16曾以七机编队、歼-11B曾以九机编队参与排练那样。
1、2、3、4、5
但在正式阅兵时，除歼-15之外的受阅各重型机单位，却均以相比彩排时减少2机的形式展示，9机变7机也许还好，但7机变5机就有点hold不住了，歼-20编队在五机变三机之后更是显得单薄了些。
相比密密实实的楔形编队，人字形编队的填充感不足，在视觉上也是个问题。所以。。。。。。要是能六机编队就更好了！
那么咱就随便开个脑洞，如果在歼-10B-TVC低速大迎角缓慢通场后，歼-20五机编队高速掠过超车，来个水平开花同时放油，致敬那份未能在“1708”任务中正式显露的风采。。。。。。哎，若是能得亲见此番豪情，也是无憾了。
为了应对天气等因素的影响，各种机型在航展上的飞行动作都会有多种难度不同的预案，教练-10在长春开放日上的表现就是一例。最终领导会拍板决定哪个呢？现在只有天知道
五机编队除了够豪迈之外，咱觉得还有个好处：从三机到五机，一旦有了这种“水涨船高”的展示势头，那么等到“1019”任务（2019年10月1日国庆70周年阅兵任务的代称，在之后这几个月，这个代称在本号的使用频率会越来越高），歼-20如果不来个7机编队，对不对得起观众另说，您想想咱们老百姓都见证过五机编队了，大老板们要是在城楼上还是看个五机编队。。。。。。
那还怎么体现我们处于、并将继续保持亚洲国家中四代机数量最多的地位呢（谁提人均我就不高兴了啊）！（作者署名：扬基帧察站）

再过不到一个星期，两年一度的珠海航展即将开幕。这一届，无疑将是展示中国军民用航空工业最新成就的舞台，就在这两天，2种代表国产最先进战斗机和发动机水平的战斗机——歼-10B推力矢量（TVC）验证机和空军某基地的歼-20战斗机，都已在航展现场进行提前适应，让军迷大呼过瘾。
作为本届航展的“神秘来宾”，歼-10B推力矢量验证机去年才完成首飞，今年就已公开亮相，“尺度”之大，令军迷和即将观展的吃瓜群众欢呼雀跃，毕竟，推力矢量发动机是让战斗机拥有超机动能力的“黑科技”，在过去只有美俄等少数国家掌握，中国的推力矢量发动机经过了近20年攻关后，才有了开花结果的一天。

军迷们发回了很多歼-10B推力矢量验证机降落珠海机场的特写照片。这种在涡扇-10B改进型太行发动机上研发的推力矢量发动机，是一种采用轴对称矢量喷管的先进TVC发动机，喷管可上下左右活动，在范围上要超过F-22所用的F119和苏-35所用的117S，这架歼-10B推力矢量验证机尾部还装有防尾旋伞安装支架，防止在超机动过程中瞬间失速，使用防尾旋伞可及时改出。
图片：歼-10B的太行TVC发动机特写，防尾旋伞基座很明显
这种发动机目前在歼-10B上测试，很大程度上应该是为歼-20验证关键技术。
要知道，一架代号2021的歼-20的批生产型原型机，正装上推力14吨级的涡扇-10B发动机进行测试，它还是采用红外隐形喷管的改进型，因此不久的未来，歼-20装上歼-10B的这种推力矢量版涡扇-10B，会是大概率事件，可作为歼-20第一阶段大规模量产的目标发动机，同时也为歼-20第二阶段量产的目标发动机——涡扇-15应用TVC技术打牢基础。

与此同时，随着航展步伐接近，来自空军现役的歼-20战斗机，已在这两天以2批次双机编队飞行的形式，飞抵航展现场进行“彩排”，这些歼-20来自数千公里以外的北方某地，为了在航展上让军迷一睹它的风采，提前飞抵珠海附近某空军机场，这种“前出部署”的能力，何尝不是一种实战化能力呢？

今年是第十二届珠海航展，过去的十一届航展上，我们亲眼见证了中国军民用航空工业的两次大飞跃。
1996年首届开幕的时候，我们还曾是歼-8IIM、歼-7MG唱主角，看着俄罗斯的苏-30直流口水，2008年后，歼-10、直-10、运-20这些代表中国军机追赶世界先进水平的机型纷纷参展，让军迷们倍感幸福，而2014年后，歼-31，歼-20的公开亮相，更是让军迷们幸福得如同一朵花。
图片：曾经，歼-8IIM也寄托了中国军迷所有的梦想
这个展示中国军民用航空工业自主创新发展成果的舞台上，还会给军迷，给全世界更多的惊喜，让我们拭目以待。（作者署名：乌龙防务评论 微信公众号：wulongfangwu1 ）

The vector version of the 航10B will be performed at the Zhuhai Air Show.
The vector version of the 航10B will be performed at the Zhuhai Air Show.

When I wrote the preview of the air show last time, although many people said in the message that they were "not interesting and didn't want to go", there are still some readers and friends who have guessed what I have sent through the F-16 MATV and the legend. .
Today, it is like a contract. It was first publicly displayed at the Zhuhai Air Show in 2008 from the 歼-10 in 2008, exactly 10 years. In this way, at least in the minds of most people who eat melons, this air show also has meaning and meaning.
There is a pair of fuel tanks that hang around, and there is a pair of smoking devices. The mounting base of the anti-tail umbrella stand on the rear fuselage is also kept.

Recently, the 歼10 vector propulsion verification machine was unveiled in Zhuhai, and some netizens analyzed the details of the engine nozzle. The end of the 歼10's tab may also use a thin-walled and hem-like structure similar to the F135 engine, which reduces weight and moment of inertia while increasing strength to suppress vibration. (Source: Exploring the Moon, New Vision of Aviation - Red Guard, Vertical Popularity JacKsonbobo)
The first public appearance of the 歼-10B-TVC (so called), the biggest change in painting is the number of "1034" on the vertical tail (10 stands for 歼10 series aircraft; 3 stands for the third model - 1 stands for 10, 2 stands for 10S, 3 naturally stands for 10B; 4 stands for the 4th prototype). The original red font (the tactical aircraft number of the test flight is mostly red) is changed to a yellow font similar to that used by our military.
As early as the 歼-10B was still in the flight test phase (early 2013), its prototype was also painted with the same color font number. The difference between the machine and the 歼-10B-TVC can be seen.
According to the official notice, at the air show, the 歼-10B of our army's active service will continue to participate in the static display. In this way, the "quasi-active coating" of the 歼-10B-TVC can give people a feeling that TVC technology can be used in our military.
However, the verification machine is a verification machine after all. It is not good to predict whether it can promote the foreign trade of the J-10. After all, in addition to the customers of the Su-30MKI series aircraft sold in Russia, there are not many buyers who are really interested in TVC technology.
Many users have bought the Su-30MKI system, which is not a big addiction to the AL-31FP. More fancy is its phased array radar. Who is called Su-30MKK is a slower step?
However, as reflected in previous air shows, this year's Zhuhai Air Show will also bear part of the functions of the Chinese Air Force and the aviation industry. In addition to demonstrating the excellent aerodynamic design and advanced flight control technology of the J-10, the flight display of the J-10B-TVC, for the second independent exhibition of the Hangfa Group, is also showing China that is still controversial outside the industry. An important opportunity for the technical strength of Hangfa Industry.
Things are always going well, and the 歼-20 using domestic engines will not just stay on the prototype.
Speaking back to this 歼-10B-TVC, according to a big cockroach who had witnessed the flight test scene at the test flight theater -10TVC, "Look at it and twist the butt, forget the Su Sanwu", after all, seeing is believing, then count him The words are not rough.
What is this ability to achieve?
Although in the manual, the available angle of attack of the J-10 is not too big, I mentioned in the analysis of the domestic vector thrust engine last year that it was limited to the time of the J-10 final test flight (1998-2003). Under objective conditions, its flight performance at high angle of attack has not been fully explored.
For the 歼-10 series aircraft with a relaxed static stability layout and excellent agility, it is fully equipped with the pre-conditions for the “Cobra” maneuver – at low speed, the main wing can provide enough head-up torque to allow the aircraft to quickly raise its head. The active differentially controlled canard can maintain the symmetry of the vortex on the left and right sides to prevent the aircraft from yawing in the process; although it is not a double vertical layout like the Su-27, its tall single tail + The double pelvic fins still maintain a good yaw stability at high angles of attack. . . . . .
The main wing of the J-10 has no extended side strips, which saves the trouble of the eddy current asymmetry caused by the edge strips at the high angle of attack of the side-guard aircraft.
But the next move is indispensable for the engine: although the 歼-10 with a large-area delta wing, in theory, has a good low-head characteristic under the action of the oncoming airflow; but due to its larger area, the position of the canard and main wing The relationship problem, the additional head-up torque at this time will make the head time longer; at this time, the direct head torque provided by the vector thrust engine helps the aircraft to smoothly pass the bow stage as soon as possible.
Of course, when playing this game, the engine has to have excellent anti-surge performance. If you can't play it, it will turn off. From the performance of the game before, 606 obviously has anti-asthma for "Taihang". Ability to improve
In addition, the three-axis TVC can also offset the possible yaw moment while providing the head torque. . . . . . However, I personally think that the J-10, which has certain active control capabilities, should be more concerned with how to use the yaw moment to play more flowers.
Taking the Su-35 as an example, since the nose is back, why not point the nose at low speed to the extreme? Falling leaves rise!
Even if the nose is still up, apply a yaw moment and use the 歼-10's good head-up characteristics to throw the cake away!
So, the intention of the two dark blue smoking devices hanging under the 歼-10B-TVC wing (this color, apparently from the August 1st Air Show Team) is obvious.
Speaking of the F-16C and AH-64D formations, many people think of the daily performance of the country's air force at the Singapore Air Show. However, the Dutch Air Force has similar projects, showing the former's excellent low-speed high angle of attack performance, pay attention to the F-16 wingtip smoke extraction equipment.
In addition to better sketching the performance of the 歼-10 performance, think about the two pods in the pneumatic and weight is also equivalent to hanging two fighting bombs, which can give people a sense of real thieves! Although it is inevitable to increase the weight after modifying the vector engine, since it is an air show performance, the 歼-10B-TVC can completely maintain the “light body as a swallow” by reducing the amount of oil, and offer a visual effect that does not lose the color of the Su-35. Experience.
A flower is not open. As early as the 歼-10B-TVC arrived in Zhuhai, a number of 歼-20s had already been transferred to a station in the Southern Theater Air Force. Despite the static display. . . . . . That is definitely not going to be there, but the scale of the dynamic display is definitely stronger than the previous one.
In the past two years, with the delivery of multiple units to the 歼-20, a certain amount of equipment has been accumulated while the exposure rate has gradually increased.
Speaking of this scale, before and after the military parade on July 30 last year, the official release of the cockpit -20 formation cockpit perspective, some people saw that the first air force training base of the 歼-20 was in the rehearsal Once represented by a five-machine formation, as in the case of the 歼-16, the seven-machine formation, the 歼-11B used the nine-machine formation to participate in the rehearsal.
1, 2, 3, 4, 5
However, in the official military parade, all the heavy-duty units except the 歼-15 were shown in the form of two machines less than the rehearsal. The 9-machine 7 machine may be okay, but the 7-machine 5 machine is a bit hold. Can not live, the 歼-20 formation is even thinner after the five machines changed to three machines.
Compared to the dense wedge formation, the herringbone formation has insufficient filling and is also a visual problem. and so. . . . . . It would be better if you could form a six-machine formation!
Then you just open a brain hole. If you slow down the 歼-10B-TVC low-speed angle of attack, the 歼-20 five-machine formation will pass the overtaking at a high speed, and the level will bloom at the same time, and the tribute will not be Officially revealed in the "1708" mission. . . . . . Hey, if you can get this love, you have no regrets.
In order to cope with the influence of weather and other factors, the flight movements of various models at the air show will have a variety of different difficulty plans. The performance of Coach-10 on Changchun Open Day is an example. Which leader will decide the final decision? Now only God knows
In addition to being bold enough, the five-machine formation feels that there is still a benefit: from the three machines to the five machines, once this "water rise" is exhibited, then wait until the "1019" mission (National Day 70, October 1, 2019) The name of the anniversary parade mission, in the following months, this generation will be used more and more frequently in this number.) 歼-20 If you don’t come to a 7-machine formation, you can say that you are not worthy of the audience. The common people have witnessed the formation of five aircraft, and the big bosses are still watching a five-machine formation on the tower. . . . . .
How does it reflect that we are and will continue to maintain the status of the fourth generation of machines in Asian countries? (Whoever mentions people, I am not happy)! (Author's signature: Yankee Frame Station)

In less than a week, the biennial Zhuhai Air Show is about to open. This session will undoubtedly be the stage to showcase the latest achievements of the Chinese military and civil aviation industry. In these two days, two kinds of fighters representing the most advanced fighters and engine-level fighters in China - the 歼-10B thrust vector (TVC) verification machine and the air force The 歼-20 fighters of a certain base have been adapted in advance at the air show site, making the army fans enjoy themselves.
As the "mystery guest" of this year's air show, the 歼-10B thrust vector verification machine completed its first flight last year. It has been publicly unveiled this year. The "scale" is so big that the army fans and the people who are about to watch the show are cheering. After all, The thrust vector engine is a "black technology" that allows the fighter to have super-maneuverability. In the past, only a few countries such as the United States and Russia have mastered it. After nearly 20 years of research, China's thrust vector engine has had a day of flowering.

The military fans sent back a lot of close-up photos of the 歼-10B thrust vector verification machine landing at Zhuhai Airport. The thrust vector engine developed on the turbofan-10B modified Taihang engine is an advanced TVC engine with an axisymmetric vector nozzle. The nozzle can move up and down and left and right, and the F119 used in the F-22 is beyond the range. The 117S used in the Su-35, the rear end of the 歼-10B thrust vector verification machine is also equipped with an anti-tailed umbrella mounting bracket to prevent instantaneous stall in the super-maneuvering process, and can be changed in time using the anti-tailing umbrella.

This type of engine is currently being tested on the J-10B and should largely be verified for the 歼-20 key technology.
It should be noted that a batch prototype of the 歼-20, code-named 2021, is being tested with a 14-ton thrust turbo--10B engine. It is also an improved version of the infrared stealth nozzle, so in the near future, 歼-20 This kind of thrust vector version turbofan-10B equipped with 歼-10B will be a high probability event, which can be used as the target engine for the mass production of the first stage of the 歼-20, and also the second stage of the 歼-20. The target engine, the turbofan-15, is based on TVC technology.

At the same time, with the approach of the air show, the 歼-20 fighter jets from the Air Force's active service have already flew to the air show site for rehearsal in the form of two batches of two-machine formation flying in these two days. In a certain place in the north from thousands of kilometers away, in order to let military fans glimpse its style at the air show and fly to an air force airport near Zhuhai in advance, this ability of "pre-distribution" is not a practical ability. What?

This year is the 12th Zhuhai Air Show. At the past 11th Air Show, we witnessed two great leaps in the Chinese military and civil aviation industry.
At the opening of the first opening in 1996, we also played the leading role of the 歼-8IIM and 歼-7MG, watching the Su-30 DC slobber in Russia. After 2008, 歼-10, Zhi-10, Yun-20, these are the Chinese military aircraft to catch up. The world's advanced models have been exhibited, so that the military fans are more happy, and after 2014, the public appearance of the 歼-31, 歼-20, is to make the military fans happy as a flower.
Photo: Once, the 歼-8IIM also pinned all the dreams of Chinese military fans.
On the stage of demonstrating the achievements of independent innovation and development of the Chinese military and civil aviation industry, we will also give military fans more surprises to the world, let us wait and see.

Trump hits Chinese chipmaker with export ban, still expects ‘great deal’ with Beijing
