Chinese and Russian jet engines fail

When a Chinese-designed jet fighter crashed, local media found fault with the imported Russian engine while praising the injured pilot for his “outstanding soldier’s conviction” during the incident. 

According to a report by the Beijing-based Sina Military Network, the Russian-built engine used in the J-10 is prone to malfunction, having caused multiple crashes in recent years.

On Sept. 19. a J-10 fighter jet from northeastern China’s Shenyang Military Region crashed during a nighttime patrol mission, state-run China Central Television (CCTV) reported. The Russian-built engine had lost power at over 11,000 feet, said pilot Li Tong, who ejected at 1,000 feet following an abortive 198-second attempt to glide the aircraft to a local airfield.

Li survived with neck and spine injuries. Because he had avoided lit, populated areas when maneuvering his damaged plane, CCTV lauded him as a hero, saying that he had made no less than five “weighty decisions” to “avoid the loss of property and life among the masses.”

A distinguished military pilot, Li Tong told CCTV that his first priority was to save the jet, which at the time of engine failure was carrying 200 rounds of aircraft ordnance and 2.5 tons of fuel. As Li struggled to restart the engine, the plane fell to about 5,000 feet.
Why a Russian Engine?

The J-10 is a single-engine light fighter aircraft that was developed by the Chengdu Aircraft Corporation in the 1990s and put into service starting 2005. It is built around the powerful Russian AL-31 engine, which was originally intended for the two-engined Su-27 family of Soviet-designed fighter aircraft.

With its Western-inspired and locally-designed single-engine configuration, however, the J-10 suffers from severe compatibility issues in using the AL-31. At the same time, the Chinese-designed WS-10 aircraft engines have proven even less reliable than the Russian equipment.


Despite claims made in 2014 by a spokesman for the Chinese research institute tasked with the WS-10’s development that the engine was “fully operational and matured” for use in an upgraded J-10, a Sina report this August revealed that the Chinese aviation industry had yet to reduce the Taihang’s failure rate to within acceptable boundaries. The Chinese air force and in particular the J-10 jets will continue to run Russian engines.

According to Chinese naval publications cited by Sina, consultations with Russian providers to find a solution for the AL-31 compatibility issues have been delayed for want of funding.

“Measures to address failures from the perspective of design theory cannot be given,” the Sina report thus said. 

Netizens found issue with the Chinese media reports and analysis of the September crash, saying that CCTV’s triumphant depiction of the pilot’s emergency actions drew attention away from the technical failings common to modern Chinese fighters.

A user in Guangdong Province contradicted the Sina analysis for its implication that the engine can simply be re-engineered, if only the Russians would help. “The engine is not like a graphics card that can be changed at will,” the post reads. “It is integrated with the entire airframe.”

“What if the aircraft was severely damaged, or if the pilot had no time to process the malfunction? Never make a trifle of human life,” a netizen from Shanghai said, criticizing the CCTV report for its rosy depiction of Li Tong’s flight and crash that “avoided residential areas.”

Top 10 linux commands

Hello and welcome to our blog. In this tutorial we are going to learn 14 useful linux commands
like Uptime,Users,Sudo,cmp,lsusb, lsmod,lsblk ,ifconfig interface up,ifconfig interface down,dd,lsop,bc,last reboot,Vim and Watch. Let us start with command uptime

Uptime

The command uptime will show you the how long system has been running, how many users currently logged on and system load averages.

[root@faraz ~]# uptime
14:23:55 up  2:36,  3 users,  load average: 0.05, 0.18, 0.12
[root@faraz ~]#

Users

This command will print the names of users currently logged in to current host. Here it is showing two times login fahmed users and one time root.

[root@faraz ~]# users
fahmed fahmed root
[root@faraz ~]#

Sudo

This will execute the command as another user with privileges and allow the user to work as superuser as specified by a security policy. First you need to edit the visudo file and make an entry for user with privileges.  In the section group wheel make entry for fahmed user (%fahmed ALL=(ALL)       ALL)

[root@faraz ~]# visudo

## Allows people in group wheel to run all commands

%wheel  ALL=(ALL)       ALL
%fahmed ALL=(ALL)       ALL

Now you are able to use commands with privileges and you have the rights to execute.

[fahmed@faraz ~]$ sudo systemctl start smb
[fahmed@faraz ~]$

So far we have been starting/stopping services start with root user but now  here sudo user can also start/stop the service as well.

cmp

This command compare two files byte by byte and will display difference.
Syntax cmp file1 file2

[fahmed@faraz ~]$ cmp newstring.file upload.txt
newstring.file upload.txt differ: byte 1, line 1
[fahmed@faraz ~]$

lsusb

This command will list the usb devices. As you can see in below image I have connected my usb with Kingston technology.

[fahmed@faraz ~]$ lsusb
Bus 001 Device 002: ID 0951:16a3 Kingston Technology
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
[fahmed@faraz ~]$

Enable an Interface

You can enable system’s interface up by defining the name of the interface with ifconfig command. In CentOS/RedHat 7 interface card name is enp0s3. Older version has eth0.
Syntax ifconfig  interface-name  up

[fahmed@faraz ~]$ sudo ifconfig enp0s3 up
[fahmed@faraz ~]$

Disable an Interface

You can also disable the interface card.
Syntax ifconfig interface-name down

[fahmed@faraz ~]$ sudo ifconfig enp0s3 down
[fahmed@faraz ~]$

dd

This command will copy a file, converts and formats data according to the operands. This command is mostly used to copy the iso image into usb device or other media devices through if= input file and of=output file.

[root@faraz ~]# dd if=/dev/dvdrw of=/home/fahmed/Downloads/CentOS.iso

Be careful when you are defining the name of device (dvd or usb etc)

lsop

This command will list all the information about opened file in a file system (Like regular file, library file, network related file etc). Here I am going to show first top ten opened file because of lots of files are opened there  in backend.

[root@faraz ~]# lsof | head -10

Vim
You can open file with vi or vim but how can we open file with or go to that particular line. Here I am going to open file with particular line. Syntax vi +line-number file-name

[fahmed@faraz ~]$ vi +10 newstring.file

Watch
This command is to execute a program and watch the program output changing over time. By default its run on every 2 seconds. Its display output and errors in full screen. It is basically watching the program in continuous form with time interval. You can run multiple commands at a time inside the quotes.

[root@faraz ~]# watch -n 1 'ls -l; echo; df'

Wisconsin and other states should vote Ted Cruz, save NATO, and go to a contested convention.

In an interview on ABC's "This Week," Donald Trump says that the Cold War-era alliance headquartered in Brussels has been revealed as "obsolete" following devastating terrorist attacks in that city this week.

"NATO doesn't discuss terrorism," Trump said. "NATO's not meant for terrorism. NATO doesn't have the right countries in it for terrorism."

NATO forces from Germany and Britain did deploy to Afghanistan after 9/11.

"NATO was done at a time you had the Soviet Union, which was obviously larger -- much larger than Russia is today. I'm not saying Russia is not a threat," Trump explained. "But we have other threats. We have the threat of terrorism."

Transcript:

JONATHAN KARL, ABC NEWS: OK, let's turn to the attacks in Brussels. The State Department has issued an extraordinary warning for all of Europe.

Do you think that Europe, right now, is a safe place for Americans to travel?

TRUMP: Well, I'm the only one that predicted it. I said Brussels is a hellhole and "The New York Times" mocked me and -- and said, a couple of months ago, "The New York Times" did a big story about how dare Donald Trump say Brussels is a hellhole, how dare they?

And then all of a sudden, it came out the attack took place in Brussels.

I understand what's going on around the world far better than these politicians do. I'm all over it.

KARL: But (INAUDIBLE)...

TRUMP: And I have friends that are all over the world.

I will tell you, I was -- I was really hit hard by "The New York Times" in an article, how dare I attack Brussels?

And now this happened. And, you know, the biggest thing on the Internet, one of the big things on the Internet was that Trump was 100 percent right about Brussels.

KARL: But -- but right now, do you think that Brussels is -- that Europe is a safe place for Americans?

More to the point, would you feel comfortable traveling to Europe right now with your family?

TRUMP: I don't think America is a safe place for Americans, if you want to know the truth. I don't think Bruss -- England or I don't think that Europe is a safe place. No, I don't. I think there are a lot of problems in Europe that are very, very severe.

Weak -- you know, the -- lots of the free world has become weak. When you look at Brussels, when you look at the way they've handled things from law enforcement standpoints, when you look at Paris, when you look at so many other places, no, it's not.

But neither is the United States a safe place, because we're allowing thousands of people to come in here. Nobody knows where they're from. Nobody knows who they are and they're coming in here by the thousands. And let me tell you something, we're going to have problems -- for -- just as big or bigger than they've got.

KARL: Now, you -- you gave a series of interviews, "New York Times," "Washington Post," on -- on foreign policy. In both of those, you suggested that NATO, uh, needs to do more to carry its weight.

I want to ask you about NATO code -- NATO's Article Five on collective defense, which, of course, goes back to the very beginning of the cold war.

Is that something that is simply out of date and needs to be maybe done away with?

TRUMP: I think NATO is obsolete. NATO was done at a time you had the Soviet Union, which was obviously larger -- much larger than Russia is today. I'm not saying Russia is not a threat.

But we have other threats. We have the threat of terrorism. And NATO doesn't discuss terrorism. NATO's not meant for terrorism. NATO doesn't have the right countries in it for terrorism.

And what I'm saying is that we pay, number one, a totally disproportionate share of NATO. We're spending -- the biggest alliance share is paid for by us, disproportionate to other countries.

And if you look at the Ukraine, we're the ones always fighting on the Ukraine. I never hear any other countries even mentioned and we're fighting constantly. We're talking about Ukraine, get out, do this, do that.

And I mean Ukraine is very far away from us.

How come the countries near the Ukraine, surrounding the Ukraine, how come they're not opening up and they're not at least protesting?

I never hear anything from anybody except the United States.

What I'm saying is NATO is obsolete. NATO is -- is obsolete and it's extremely expensive for the United States, disproportionately so. And we should readjust NATO.

And it's going to have to be either readjusted to take care of terrorism. Or we're going to have to set up a new -- a new coalition, a new group of -- of the countries to handle terrorism, because ter -- terrorism is out of control.

KARL: But Ukraine is not a member of NATO. I mean there are no U.S. troops involved in Ukraine.

TRUMP: I'm not saying they're a member. What I'm saying about Ukraine is when we want to protect -- you know, when we're -- we're talk -- when Russia is going into Ukraine, we immediately get NATO.

I don't hear from the other countries. I don't hear that having to do with Ukraine. I don't hear from the other countries in NATO. I don't hear from Germany. I don't hear from -- I only hear from the United States.

We've got to, you know, do this and we're constantly telling Russia what to do. And it's all fine if everybody partakes. But I don't see other people partaking.

And then you say why are we paying -- Jon, why are we paying disproportionately the costs of NATO?

We're paying a tremendous amount more than we should be from the standpoint of proportion.

So, uh, I look at, I look at the fact that it was a long time ago.

You know, there's nothing wrong with saying that a concept was good, but now it's obsolete or now it's outmoded.

Now, it can be trimmed up and it can be, uh, it can be reconfigured and you can call it NATO, but it's going to be changed. I mean this thing was -- was done many decades ago. And there's nothing wrong with saying it's obsolete. But it is obsolete.

And, by the way, I took a lot of heat for saying that and now everyone is agreeing with me. I mean I'm reading -- I'm reading pages of -- of, uh, of media where now people are agreeing with me.

I always take heat. I mean I -- I listened to somebody this morning on one of your competing channels talking about "The Washington Post." I gave a very good interview to "The Washington Post." And frankly, uh, I thought it was very good.

You know, it's very interesting, everybody was knocking on NATO, like they do usually -- when I talk about -- when I talk about illegal immigration. I went -- I went through hell with illegal immigration. Now everyone is saying Trump is right.

When I talked about the problems that we have with trade. Now they're all saying Trump is right. The same thing with NATO.

When I did that, two days I took abuse from the media falsely. Now, people are saying -- many, many people are saying, you know, Trump is right. He's absolutely right about NATO.

Don't die "bloggie"

For some reason for  April Fools, this blog was removed from Google's front page search for Iain's blog . This never happened before. This blog is 12 years old.  The Canadian orgcode must really hate it (whose is first hit).  I thought we had a mutual agreement by leaving one another alone.
