China tries to hide J-10 fighter crashes

Buddy, please read the so-called Chinese source, nothing but about the introduction of J-10, amazing "Indians propaganda" demo in full force.

All they want to prove is that Chinese J-10 is not an advance air craft that their export customers think twice before placing any order.

Can someone tell these idiots that the advance technologies are massured more through their performance and capabilities rather than crashes to some extent.

If that is not the case than you saw F-22 crashes too , MKI Crashes so does it prove that those jets are just a piece of crap ??

No way ..:coffee:

no one want to show that
thats fact
but why chinies gov hide it
and there not only mig who crash all the time ... other planes are also so keep in mind before making fun of any mig crash

I search "J-10坠毁(crash)" from Baidu,and get 37800 pages,any evidence of "but why chinies gov hide it"??????
And Indian gov even hide the detail of 1962 now~~

Quote from the article

In the past it has exported fighter aircraft to Iran, Myanmar, Bangladesh and Pakistan. However, the pitfalls of reverse engineering without paying royalty and truly understanding the technology are high accident rates, a fact that China has hushed up with its lack of media freedom.

Just a question.

What are the number of crashes of cheap chinese copy and High quality russian Air crafts.

seems like the indian media BS is on full display again, even their own souce says nothing about hiding the crash, members have proven that plenty of results have come up in chinese internet search, so close this thread and move on.

i said it before, here's a reminder.

the problem with the source is its lack of technical information and poor use of terms.

reverse engineering without understanding the technology.

very interesting comment.

what is reverse engineering, and what is understanding the technology? as any engineer knows, the way to get something from idea to concept is design, build, test. reverse engineering is a reverse flow of information from an already built and tested model, to drawing up the blueprints for it. that is the most basic step.

however, there are always parts that cannot be copied. in fact, the vast majority of parts cannot be copied due to incompatability with existing systems and equipment.

if anyone has doubts, try making a blueprint of a radio/alarm clock by taking it apart. I'm not asking anyone to manufacture a radio/alarm clock, that requires special equipment, but just to make a blueprint of a radio/alarm clock exact enough that someone else with that equipment can create a hard copy from scratch using only those instructions.

And how do you measure performance unless you have flight testings?

There are two types of flight testings:

- Developmental
- Operational

Developmental flight testings are usually done by the manufacturer. DFT are usually for, first 'proof-of-concepts', then to expose assorted defects such as those from manufacturing processes or cockpit layouts flaws or material strengths...etc...etc...The list is considerable.

Operational flight testings are usually done by the customer. OFT are usually manned by specialists who are trained, not only how an aircraft is supposed to perform and maintained in the field but also on how to provide feedbacks to the manufacturer on correcting defects that could impair field deployments.

So we can be certain that OFT naturally follows DFT. I do not see how China would follow any other course.

Where are these mishaps, at the DFT or OFT? Why are there efforts by the government, aka the manufacturer, to hide these catastrophic mishaps? It is reasonable if the manufacturer does not want to publicize DFT mishaps. What for when DFT are for 'proof-of-concepts' or to find assorted flaws AFTER those concepts are proven to be viable? But it is telling if the government, aka the manufacturer, is trying to conceal catastrophic OFT mishaps. Remember, it is the customer, not the manufacturer, who is responsible for field maintenance and this is after money have been exchanged. An OFT does not need to be done by an actual buying customer. An OFT can actually be done by the manufacturer himself as he is putting himself into the customer's shoes, so to speak, then he hands the product off to a potential client, who do his own OFT.

So if the Chinese government is hiding OFT mishaps, the J-10's potential clients had better be careful.

Am going to use a simple hydraulics example to clarify the difference between Developmental and Operational flight testing...

During DFT, hydraulics is a proven concept. So the DFT would test if the hydraulic hose has sufficient strength to withstand 3000 lbs psi. Same for the coupling.

Suppose an OFT crew opens a panel to gain access to an electrical wire bundle and find a hard hydraulic line in the way. They can access the wire bundle well enough to perform simulated repairs. Can they petition the manufacturer to reposition this hard hydraulic line or replace it with a flexible line as they present evidence that it would decrease the maintenance time for that electrical wire bundle? Yes...They can so petition.

The manufacturer would study the feasibility of both options. In hydraulics, it is preferable to have hard lines as much as possible. The manufacturer may have to increase the purchase price a bit to compensate for a change. He may also find unexpected peripheral changes to other systems that may not justify the desired and requested change. In that case, some understandings must happen between the two sides. The customer may have no choice but to live with the hydraulic line as is.

This is the basic difference between DFT and OFT.
