Youtube daily report Dec 26 2018

Our top story this morning South and North Korea are set to hold their groundbreaking

ceremony in North Korea for linking and

modernizing railways and roads between the two Koreas this comes eight months after the leaders of Seoul and Pyongyang first

agreed to work together on the project it wasn't exactly smooth sailing due to a lack of progress in the

North Korea us negotiations but after many twists and turns

South and North Korea are indeed you to hold this groundbreaking ceremony before we bid farewell to

2018 we have our Unification Ministry correspondent song he joining us live from dorasan station

Which is the northernmost train station in South Korea jeonggi good morning

Good morning mark I'm standing at for asan station just

700 meters away from the Demilitarized Zone

if trees really do get to travel back and forth between South and North Korea then this will be the last station before

you cross the border into the north

earlier this morning the South Koreans attending today's groundbreaking

Ceremony passed through this station and are expected to have arrived at the North Penman station an hour ago that's

Exactly where today's groundbreaking ceremony will take place from 10:00 a.m

just about now there are 100 participants each from South and North Korea from North Korea Lee seung-hwan the head of Pyongyang's

Reunification committee is to be at the event with senior North Korean officials from the Economic Cooperation

Committee in vice ministers of railway in land from the south Seoul's Transport and unification

ministers Kim Hyung Mian - myung-hoon are attending along with the leaders of South Korea's political parties and rail and road related officials a

few South Koreans who lived in the north before being displaced by war have been invited as well

Along with the engineer who who last ran trains across the border let's have a listen to what they had to say this morning

I'm very excited and I think I'm very lucky

There are a lot of us who had to live our hometown it'd be great if all of us could go and visit our hometown

By train, we're all old is our big wish to go there by train

It's been 10 years since I last rent range to the north via Kong a rail line

Back then I didn't have any special thoughts but after it was all suspended and I retired

I've been thinking when will I ever get to go there again it's great that I get to visit there again

Okay, well Jonny they must be extremely excited to be making this trip we're hearing though that there are also

Participants at today's event who are not from the Korean Peninsula can you tell us?

about

who they are and also

does their presence mean that this massive transport project could actually begin right away

Well mark to answer your first question

guests top railway and road officials from

China Russia and Mongolia will be at the groundbreaking ceremony today and that as

inter-korean railways could eventually be linked to railways cutting across these three countries to join the

Translation rail network in the future

also the executive secretary of the UN's

Economic and social commission for Asia and the Pacific is coming for assuming her presence is because of a project called the Asian highway

Network for a un escape and countries in Asia and Europe aim to connect highways that cross the continent and reach Europe a couple

Of proposed routes pass through the two Koreas but even if we have caught a number of high-level figures coming to the events today's groundbreaking

Ceremony doesn't mean that the two Koreas will kick-start related construction right away the two Koreas have

received sanctions waivers from the UN Security Council for on-site

Surveys and today's ceremony but that doesn't mean these waivers will apply to whatever work happens in the future

Seoul also plans to do more detailed surveys before coming up with

construction

Plans South Korea says the actual construction work won't begin yet and things will go in accordance with progress on North Korea's denuclearization

And following waivers on sanctions back to you mark

How the Vice team built their genre-busting, fourth-wall-breaking Dick Cheney satire - Duration: 38:06.

 Vice may not be the most conventionally festive movie, but when it hits theaters on Christmas day, writer-director Adam McKay hopes his Dick Cheney biopic becomes part of your holiday traditions nonetheless

 "What better thing is there on Christmas morning when your children run downstairs and rip open the presents than to see Dick Cheney sitting under your Christmas tree?" McKay says with a laugh

 Like McKay's 2015 drama The Big Short (which netted him an Oscar for best adapted screenplay), Vice is an ambitious, fourth-wall-breaking experiment, following Cheney (an unrecognizable Christian Bale) from lowly White House staffer to vice president

Amy Adams plays his loyal wife Lynne, with Sam Rockwell as George W. Bush and frequent McKay collaborator Steve Carell as Donald Rumsfeld

 It's an incisive portrait of a hard-to-understand-man, ping-ponging from serious drama to pure farce, with plenty of cameos and genre changes along the way

Hitting theaters Dec. 25, it's already racking up the accolades, leading this year's Golden Globes nominations with six, including best musical or comedy

 Ahead of the film's release, EW sat down with McKay, Bale, Adams, Carell, and Rockwell to talk all things Cheney — as well as fakeout endings, faux Shakespeare, and singing on set

 ENTERTAINMENT WEEKLY: So when Adam came to you all and said, "I wrote this movie about Dick Cheney," what was your initial reaction?  CHRISTIAN BALE: Well, saying that he wrote it with me in mind, I'm not sure whether to be offended at him for that, really

[Laughs] But I have to say, what an incredible leap of faith [he] took in doing that because I didn't believe that I could do it at all

It was a little bit like Dick Cheney with his fisherman's hook… I think Adam kind of knew he was going to reel me in because if I was going to do that research ahead of time, I'd start getting obsessed with it and the possibilities

So when it came to be crunch time, I just wanted to work with this crowd again, and it was just too tantalizing

 And there's always that great idea that the next project you do might be your last because you balls it up so badly that nobody will ever hire you again

So that's always a seduction.  AMY ADAMS: I think that every time. [Laughs] It seemed like an enormous challenge

Once I read the script that was all it took to hook me. Adam's script, and Christian was in it

It presented an amazing challenge, and that's something that always excites me, thinking I might fail

Why does thinking I might fail excite me?  BALE: The only problem we had to overcome was that Rockwell was going to be in it

We were like, "Oh no, Rockwell's gonna be in it." But nevertheless. [Laughs]  SAM ROCKWELL: [Laughs] Yeah, I was flattered and titillated and ready to go

It's daunting, but I was excited. And [McKay and I] had kind of crossed paths before a little bit and almost done some stuff, so I was really excited to work with this guy

 STEVE CARELL: I would do anything with Adam McKay. That's the bottom line. And I knew it would be fun

I knew it would be exciting. I knew it would involve very bold filmmaking decisions, which I love

It would be absurd. There's not a second of hesitation. I knew nothing more about it than Adam's doing a movie about Dick Cheney, and I was like, I'm in

I don't need to know any more than that.  BALE: And I think also doing the research and realizing why Adam had picked Cheney, because initially, not knowing — as many do not — much about Cheney

And I came to understand how Cheney has been such a consequential figure for decades in government and played such an important role as to how we are here today

 Adam, I know you've talked a lot about wanting to be true to this story while also having fun with it

How did you find the right balance?  ADAM MCKAY: I think from the beginning it was always a mystery, and that's what was exciting to me, reading all these great books by these different journalists and these interviews and articles and everything

I told Christian this right from the beginning: This guy does not want a movie made about him

He's done everything he can so there's not a movie made about him. He knew the spotlight was not the friend to his power

And I love that.  And the other part of this movie that was really exciting was: Who are these people who are doing these things? And where are they coming from? What are their choices, what are their motivations? And these guys went after it in a way that was just breathtaking and inspiring for me as a director

 These are characters who have been in the public eye, but they are so cryptic and notoriously private — especially Cheney himself

How did you try to understand them and get inside their heads?  BALE: For me, I'm a very slow learner

I really am. It takes a long time for me to learn, but I forget it very quickly.  MCKAY: That's a terrible combo

[Laughs]  BALE: But just sitting with it. [My phone] is just full of videos of Mr

Cheney talking and me listening and listening. My whole family is asleep, and I'm watching Dick Cheney

I'm listening to him and imitating him and trying to figure him out. [Laughs] And referencing the script

I wish I could do it more quickly, but my brain doesn't work that way. But you gradually settle into it where it hopefully becomes natural instead of a gimmick

Annapurna Pictures  What about you, Steve? How did you get inside Rumsfeld's head?  CARELL: Well, you know, there's the public and the private persona, and the private is your best guess as to who he is and what motivates him

As Christian was saying, you have the script to guide you, you have all the source material, the video tape of how he acts when he's at a press conference or in the public eye

And then you try to surmise what might lie on the other side. Adam and I were talking early on about how Nixon and Kissinger spoke of Rumsfeld and said, "You gotta watch out for that guy

" And for Nixon and Kissinger to be wary of a third person says a lot.  MCKAY: I think they said, "Watch out for that guy, he'd take his own mother out to get ahead

"  CARELL: [Laughs] Yeah. That informs a lot about who someone is behind closed doors

So you take little bits of information like that and you try to use it. But at the same time, he's a human being

You can't go in editorializing about what you might personally think about somebody

You have to remove yourself from that. Just think about them as a person with flaws, with motivations

He's a robust personality to be sure — but incredibly motivated and not someone to be messed with, obviously

And really, really smart.  George W. Bush is the figure who's most in the public eye, and he's been portrayed in so many different ways over the years

Will Ferrell was a producer on this movie, and his version of Bush is so well-known from Saturday Night Live

Sam, were you thinking about how Bush had been portrayed before at all?  ROCKWELL: Yeah, I watched all that stuff

I watched [Josh] Brolin [in W.]. I watched Will Ferrell. And Steve Bridges. And there was a guy named Frank Caliendo

So I watched that, and then I stopped watching that, and I just watched Bush. But I wanted to kind of see the template

 Some actors are different. Some actors if they're playing Hamlet or whatever, they're not gonna watch Nicol Williamson and whoever doing Hamlet before

They're just gonna wanna do their Hamlet. I like to watch all that stuff. But like these guys, I get obsessive

 Oddly, for such little screen time, it felt like a lead role because when I was away, I had to listen to him, and that was weird

It's a very small part, but I had to stay in it. It was a lot of work for that amount of time you know? [Laughs] But it was cool and most of my scenes are with [Bale], and he would do this thing where he would do the voice, so I started doing the voice

I'm not like a method guy per se, but we would sort of start talking about normal stuff, like Steve Zahn and actors we'd worked with

And we'd been in a movie together, a Shakespeare movie years ago, and we would just talk about normal stuff that we would talk about, but in the voices

So that was kind of fun, because it was a way to stay in it without being totally out of our minds

 So what was the most unconventional topic you talked about as Dick Cheney and George Bush?  ROCKWELL: Oh god, I don't know

What do you think?  MCKAY: I like Steve Zahn. Dig into that a little bit. [Laughs]  BALE: That would have been great to record, wouldn't it? Cheney and Bush talking about Steve Zahn

   MCKAY: [adopts Cheney voice] "Steve's good. He's very underrated. He brings a light to whatever he's in

"  BALE: And I mean, Sam was thrown into the deep end, wasn't he? Because his first day was the scene at the ranch

 ROCKWELL: Yeah, I was so nervous. I did this thing, I did a football slap on your bum, and I thought, "Oh no, this is not going to go well

" [Laughs] But I thought it was something Bush would do with Cheney, like a guy thing

 BALE: And then he'd probably think, "This is not going to go well." [Laughs]  ROCKWELL: Exactly! And I thought he was going to break character

He stopped and he turned and he didn't break character, and then we kept going. And then Adam said, "Hey, why don't you do that again?" and I said, "No, I think Christian's gonna knock me out if I do that

" And you started laughing. But it was fun. It was fun to play.  BALE: Sam, you can slap my ass any time

You get the green light.  ROCKWELL: Okay, good! Annapurna Pictures  Amy when you were diving into Lynne, was there something you focused on to sort of unlock who she is?  ADAMS: It's interesting

It's hard to identify exactly when it happens for me, but I do know that when it clicks, it clicks

Like all of us, I was constantly watching her, constantly listening to her, constantly reading her words to stay in her

But like these guys, I think I just stayed in voice. I was thinking about myself when they were talking about them

[Laughs] But once I stepped onto the set, I didn't really think about Amy's voice or her opinions really

I'd go in and debate with him [McKay] about the day's politics or how I felt about his wardrobe choices

 MCKAY: We would have these long conversations where she'd be in this half Lynne Cheney state

 BALE: Wasn't there singing? I'd hear you singing a lot.  ADAMS: My favorite thing to do was "Lynne sings hits from the '80s

"  Like, which hits from the '80s?  ADAMS: Like [sings] "Pour some sugar on me! In the name of love! Yes, pour some…" [Laughs] So there was a lot of singing

I apologize if it was distracting. It kept me loose.  MCKAY: Oh god, it made me laugh

And she would just walk on set and look at me in my shorts and be like, "That's an interesting outfit

"  ADAMS: I would. I would comment on how his wardrobe doesn't imply that he wants to have some authority over anybody

[Laughs] So I think I got the whole camera crew in on it too. I said, "I understand for practicality why you would wear shorts, but are there any other sort of wardrobe choices?" I found ankles offensive

 But I think what was important for me was to keep it loose. To always feel like at any moment I could move in any direction any of the actors or Adam wanted to move with the character and the story

 MCKAY: [Bale] would do it too. You sang "Happy Birthday."  BALE: I did. I got on the mic and sang "Happy Birthday

" Dick Cheney singing "Happy Birthday."  You guys should release an album.  MCKAY: You did the Queen song "Bohemian Rhapsody," which we have on camera

He did the song, "Turn around…"  BALE: Oh, a little Bonnie Tyler!  ROCKWELL: And we did some dancing in the Oval Office

 BALE: I do believe that [Sam and I] did a little bit of twerking in the Oval Office

We had a disco ball going.  MCKAY: That is correct.  I'm curious, if each of you could sit down with your character and ask them one question, what would you most want to know?  BALE: There are a lot

I mean, there are so many. I'll stay away from the deeper personal questions, which I would really love to understand from him, but there's one from early on: He's an avid fly fisherman, why did he not advocate more for the environment?  ADAMS: That is a stumper

I mean, I guess I'm gonna be really generic here, but what's your biggest regret?  MCKAY: And I think the condition has to be that they have to answer it

Because I guess Lynne wouldn't answer that. But if it was just the two of you…  ADAM: Yeah, her mouth would get very thin, and she'd know she was smarter than me 'cause she is, and she'd know she could get out of the question, which she could

Because I wouldn't press her.  ROCKWELL: I think that would be mine too. Do you have any regrets?  MCKAY: Because that would be mine as well

I'd ask Dick Cheney, has there ever been one moment in the middle of the night, where you thought, "Maybe I shouldn't have invaded Iraq

Was that really the right move?" Do you ever feel bad about anything you did when you were in office?  BALE: That's really one of the most fascinating things about him, isn't it? He's resolute 'til the end

He still says, "I'd do it again in a minute."  MCKAY: And then a question that's not about the movie but I would love the answer to is, [turns to Carell] "Did you go through my bag in the other room before this interview?" Just straight up

Just answer it.  CARELL: [quietly] Yes, I did.  MCKAY: Okay.  CARELL: [Laughs] I'd ask Rumsfeld what his relationship is like with Cheney today

I'm curious. Do they go to movies together and play putt-putt golf and things?  MCKAY: I think guys like this don't really talk a lot, do they? Huh

Yeah, Amy has never spoken to me outside of a work environment. I've seen her on the street, I've seen her at parties, and she walks right past me every time

 ADAMS: That's kind of my M.O. Just actively ignoring him. Matt Kennedy/Annapurna Pictures  I'm curious what you guys make of the sort of nostalgia for the Bush presidency that's cropped up with the current political environment

Do you feel like there's that sense of nostalgia for how things used to be?  BALE: This is where it gets so tragic

This story is ridiculous and absurd, but absolutely stunningly tragic as well. There's no comparison in terms of body count

 MCKAY: And also Trump isn't done yet, so we don't know where he's going to end up

But I think personally, a lot of us feel the same way as when I first started hearing it: I thought it was just madness

It was like, what are you talking about? And I think the line I said was, I miss the old days when my house was infested by bees, and now we've just got a wolverine loose in my house

 I want to ask about the film's structure, with all the fakeout endings and faux Shakespearean scenes and all the fourth-wall breaks

 When you read the script, was there a particular moment that made you say, "This is going to be a challenge," or "I'm particularly excited for this"?  ROCKWELL: I thought it was awesome

I thought it was like The Big Short meets Citizen Kane.  BALE: I think Adam has this unique ability to be playful in the filmmaking, while still having you deeply involved in the film

It's a fascinating thing because usually I would say, "Well, that's going to take you out of the film, and how can you be invested and how can you feel?" But oh man, I love it

Because it also gives you respite. This is a heavy topic. There's a lot of comedy to it

There's a lot of absurdity to it, but ultimately, just, the worst things happened, right? And you need that slight respite

It gives this wonderful sort of confusion and absolute spectrum of emotions that I have when I watch the film

 I don't watch many films, I assume not everyone's doing it. But as far as I know, you're the only one I've seen doing that

Fess up if I'm just ignorant. [Laughs]  MCKAY: Seventy other directors are doing it

It's kind of hack at this point. [Laughs]  BALE: But it works absolutely impeccably

He does that really well, doesn't he? Do you all agree?  ROCKWELL: Oh, absolutely

I concur.  ADAMS: I concur.  CARELL: I concur!  ADAMS: It's a line from Catch Me If You Can, so [I think of that] every time someone says, "I concur, do you concur? I concur

"  ROCKWELL: You were in that!  ADAMS: I was!  I especially want to ask about the fakeout ending

What was it like shooting that?  MCKAY: I remember our first couple of screenings, I had some filmmaker friends show up, and a couple of them were like, "This is great, man, but you can't do that

You can't do a fake ending." And I was like, oh I'm doing it! [Laughs] And then eventually when the movie got on the rails, it became one of the audience's favorite parts of the movie

They started loving it.  ADAMS: I saw the movie with my mom and that was really fun for her to be, like, checking her memory to see if there was more to the story

 BALE: Did she look at her watch? Like, "How short is this film?" "It can only be a good movie if it's over an hour 45

"  ADAMS: She actually looked at her phone. It wasn't a watch. Full disclosure: She was looking at her phone

 BALE: But beyond the comical, it is that daydream of, what if it really had been the end? We would not have had an Iraq War

We probably would not have had enhanced interrogation, wiretapping, etc. So there's great comedy to it

But there's also great meaning to it.  MCKAY: My 18-year-old daughter initially told me, "I don't like that because it made me sad, because it made me wish it had ended there

" And then in the middle of saying that, she goes, "Oh wait, I really liked that." And that's it! You're right

There is an underlying emotion. In writing this story, it so easily could have ended there

The guy had a solid career. Yeah, he was a little to the right, and he saw some dodgy things, but he did a good job as secretary of defense

I mean, he was making a fortune as a CEO of Halliburton. That could've been it, and he got that phone call

 BALE: I love it on different levels because there's the thing that he's not chasing being VP

He's being begged. That's a whole different mindset. So he can come in as VP and say, "I didn't ask for this

You asked for me to be there." But secondly, I love the fact that he's still waiting for permission

[Laughs] If he doesn't get permission from Lynne, that's the end of it.  And Adam, your daughter really helped out as well with some of the Shakespeare, right? She was very instrumental in that

 MCKAY: Yeah, both of my daughters perform in a Shakespeare for Kids group in town, which is pretty amazing

They don't do it halfway. They really put on Shakespeare. So I kind of free-formed the Shakespeare from my old improv days, just gibberish

And I said, "Lily, will you come in here? How does this look?" And she was like, "Your meter's all wrong

"  ROCKWELL: Wow, how old is she?  BALE: She's 4.  MCKAY: [Laughs] Now she's 18

She was like 16, 17. And she sat down and she's like, "No, no, Dad, you can't. Look

" So we sat down for like two hours and went through all the meter. I'd go, "But Lily, I need this line," and she's like, "Then you've got to fix the meter here

" She was like the task master.  BALE: And it worked! A friend, he genuinely thought it was from Richard III

 MCKAY: Are you serious?  BALE: He was really surprised that it was not.  MCKAY: Well, that's you guys performing the crap out of my C-minus fake Shakespeare

 ROCKWELL: What was the longest you were in makeup, you guys?  ADAMS: He [Bale] takes it

 BALE: Four hours every morning.  ROCKWELL: And you were three?  ADAMS: On my hardest days I was about three, or three and a half

 MCKAY: You were in for a while though, Steve? When you had the old guy look?  CARELL: No, I had no makeup

 ADAMS: [Laughs] You just changed your face.  CARELL: I'm able to change my face into different configurations

It's pretty incredible. Pop a bone out here or something.

为什么F22尾焰是红色,而歼20却是蓝色,难道发动机推力不足吗? - Duration: 10:59.

在科技日新月异的今天

科技逐渐改变着我们的生活。

尤其在近几年

我国在军工技术上的所取得的大突破是大家有目共睹的

国产航母下水、

辽宁舰远航归来、

055大驱呈现下饺子趋势这类举世成就不胜枚举。

如果说军迷朋友最关心的话题

除了国产航母外

那就是歼-20战机了。

要知道

歼-20作为我国自主研制的新一代隐身战斗机

它的一举一动时时刻刻牵动着国人的心

也正是歼-20的出现

使我国成为第二个可以自主研制五代机的国家

这对于我国空军而言

歼-20又将是一把利剑

时时刻刻守望着祖国的蓝天。

自歼-20亮相以来

不少人关注歼-20发动机的问题。

要知道

第五代战斗机除了隐身能力外

超音速巡航也是衡量五代机的重要标准

不少人认为

以我国目前军工科技水平歼-20发动机问题已经得到解决

也有人说我国歼-20由于发动机问题并不能够实现超音速飞行

他们给出的理由很简单

那就是歼-20的尾焰是蓝色的

而美国F-22战机尾焰确实红色的

从这一点就能判断出歼-20发动机问题。

难道战机可以通过尾焰喷出的颜色可以判断发动机的推力吗?今天小编就给大家聊聊这个有意思的话题。

据资料显示:战斗机尾焰的颜色受战机开加力程度影响!在训练中

战机一般是不会开加力的。

在不开加力的状态下

发动机内部燃料刚离开燃烧室

就会产生红色的火焰。

战机在开加力的状态下

发动机燃料燃烧非常充分

战机尾焰就会呈现偏蓝色。

另外导致战机尾焰颜色不同的还有一些其他原因

比如说:发动机位置、

发动机使用的燃料。

由此可以会所通过尾焰的颜色并不能判定发动机的性能。

另外

在美俄战机的对比中

不难看出美国战机发动机喷出的尾焰一般都是红色

俄罗斯战机发动机喷出的火焰一般都是蓝色。

而俄罗斯在战斗机领域也是屈指可数的

难道是俄罗斯发动机技术不如美国吗?非也!一般来说俄罗斯研制的战斗机燃烧室跟尾喷的距离较近

美国研制的战斗机燃烧室跟尾喷的距离较远

这也是造成美式战机跟俄制战机的尾喷颜色不一样。

再说了

战机的尾焰颜色并不是不变的

就拿F-22来说

在加力的状态下

喷出的火焰也是蓝色的

而有些俄制战机也会喷出红色火焰。

由此从战机的尾焰并不能说我国研制的歼-20推力不足。

一直以来

不少人认为F-22战机才是五代机的标准。

甚至还有一部分人认为

外国的月亮比中国圆。

殊不知

这几年我国在航空发动机领域的进步

发动机问题早已不是我国航空领域的拦路虎

更何况

最新的矢量发动机早已亮相。

过不了多久

歼-20换装适量发动机后

战力将再一次提升!加油吧!中国空军!歼-20战斗机自从亮相之后

一直受到世界各国的重视。

谁都没有想到

中国竟然能赶在俄罗斯苏-57研发成功之前搞定歼-20。

这证明中国在战斗机的研发水平上

已经赶上俄罗斯的脚步。

所以说中国的歼-20隐身战斗机对于我国航空工业来说具有非同凡响的意义。

然而即便是中国歼-20隐身战斗机战斗机研发成功了

但还是存在一个巨大的短板

那就是航空发动机和西方发达国家还存在着一定的差距。

歼-20隐身战斗机刚刚服役的时候

所装配的是俄罗斯的AL-31F发动机。

这款发动机中国空军使用的较为广泛。

但它毕竟不是中国所研发出来的

如果歼-20想达到完全的自主研发

必须换上"中国心"。

所以后来我们就给歼-20换装了涡扇-10B太行发动机。

换上这款发动机之后

歼-20的性能明显得到提升。

不论是最大航速

还是其机动性

较之前都有了一个不小的进步。

然而歼-20肯定不满足于装备涡扇-10发动机

我们的终极目标就是装备涡扇-15型发动机。

那么很多人就要问了

中国的涡扇-10B发动机已经非常先进了

何必非要研发出涡扇-15呢? 原因很简单

涡扇-15型发动机具有更大的推力

使得中国歼-20更能接近美国F-22的高机动性。

这款发动机就是专门为歼-20所研发的

所以对歼-20来说更加配套。

另外中国的涡扇-15太行发动机是我们的重要项目。

中国要想突破航空发动机领域的短板

必须研发出一款真正强大的发动机来。

所以涡扇-15项目受到国家的高度重视。

只有多方面的支持和配合

才能够提高中国航空发动机领域的水平。

期待我国的航空发动机领域能够赶上西方发达国家的脚步。

前段時間中國曝出一組畫面

這種畫面上有三架戰鬥機

分別是中國的殲-10C

殲-16戰鬥殲-20戰鬥機。

這三架戰鬥機就是中國目前的主力戰鬥機。

中國要想應對周邊日益複雜局勢必須加快這三款戰鬥機的建造和服役速度。

目前中國周邊的國家已經開始部署五代隱身戰鬥機

未來中國周邊至少會出現500架以及更多五代隱身戰鬥機力量。

這對於中國空軍來說

壓力還是不小的。

這500架隱形戰鬥機是由多國空軍戰鬥力所組成的

要讓中國一家具備對抗多國空軍隱身戰鬥力顯然是不現實的

所以中國需要用殲-10C殲-16等機型來補足中國殲-20不足的局面。

那麼很多人就要問了

中國不是購買了一批俄羅斯的蘇-35戰鬥機

為什麼不再追加購買?蘇-35是一款很不錯的四代半戰鬥機

這樣一來

中國空軍的實力也能夠在短時間內提升不少。

其實之所以中國購買24架蘇-35戰鬥機

就是因為需要補足當前中國空軍戰鬥力不足的局面

但是未來中國完全可以生產出強於蘇-35戰鬥機的版本。

蘇-35戰鬥機說白了就是一款依靠機動性能取勝的戰鬥機

然而這次航展上

我國已經展示出了軸對稱矢量發動機

那麼今後將成熟的發動機安裝到我們的戰鬥機上

性能絕對不亞於俄羅斯的蘇-35。

另外蘇-35戰鬥機和中國戰鬥機的數據量不一定是通用的

現代空軍作戰講究的是成體系作戰

不能融入中國體系的戰鬥機

始終不會成為中國的主力戰機。

看來在接下來的一段時間內

中國空軍的大梁將由殲-16

殲-10C和殲-20挑起。

自從飛機誕生以來

就以其居高臨下、

行動迅速的特點成為軍事領域的寵兒。

特別是自二戰以來

空中突襲、

空中打擊等戰術日益完善

甚至有人發出:"現代戰爭失去制空權就意味著失敗!"的驚嘆。

而針對空軍的各類防空武器也是蓬勃發展

防空作戰是任何國家的軍方都不能輕視的重要領域。

而要實現有效的防空作戰——雷達就是必不可少的用具。

傳統雷達具備遠超人類肉眼的"視距"

可以在數百甚至上千公里的距離上發現來襲的敵機

因此可以支持防空作戰部隊在儘可能遠的距離上對來襲敵機進行攔截

從而減少敵方對我方的空中打擊強度

有效保存己方的作戰力量。

雷達的基本結構其實很簡單

基本的雷達主要由兩項設備構成:發射機和接收機。

雷達的工作原理就是依靠發射機發射電磁波

當電磁波觸碰到物體時

就會被反射回來

這樣接收機通過接收雷達電磁波

並分析其波形

從而判斷發現的目標是什麼性質

如果識別出是敵機

就可以在指揮己方的防空部隊加以攔截。

因為我們肉眼可見光其實本質上也是一種電磁波

所以簡單的說

雷達天線就好比一部探照燈

通過發射電磁波

對周邊空域進行探測

一旦發現敵方目標即可對其實施攔截和打擊。

針對傳統雷達的這一特點

人類目前已經有針對性的開發出了專用隱身戰鬥機。

所謂的"隱身"戰鬥機

其實並不是肉眼看不見

而是雷達"看不見"

因為要取得合適的偵測效果

雷達所使用的電磁波波長不同於可見光

雷達波的波長設定不但要能夠判定目標性質、

還要兼顧有效"視距"

可見光由於視距較短

顯然不符合需要。

所以現代雷達通常使用毫米波和厘米波作為主要探測手段。

隱身戰鬥機就針對現代雷達所使用的電磁波頻段

採用針對性的設計

例如

外形設計成不規則多面體

這樣

當飛機被雷達波照射時

會把雷達波反射到其他方向

而不是原路反射

只要雷達的接收機接收不到回波

就意味著雷達"看不見"來襲的飛機

從而實現"隱身"功能。

除此以外

現在的四代隱身戰鬥機還大規模使用吸收雷達波的塗料噴塗在飛機表面

以便吸收雷達波

使其根本不被反射。

通過綜合優化設計

四代戰鬥機的雷達波反射水平僅相當於典型三代機的百分之一

甚至萬分之一!例如三代的F-15戰鬥機

正常雷達反射面積(RCS)為3~5平方米;四代的F-22戰鬥機

體積大小和F-15差不多

但RCS只有0.

001平方米!
