48 years ago, my country was given a "Chinook*** why can't it be imitated today?".
During the Vietnam War, China had long-term assistance to Vietnam, not only sent volunteers to resist the United States and aid Vietnam, but also supported Vietnam from the economic, material and other aspects, of course, at that time, Vietnam did not have "revenge", and the relationship between China and Vietnam was also in the "honeymoon period", so in 1975, when Vietnam in order to thank our country for its assistance, it presented a US transport captured on the battlefield to our country.
After receiving this ***, my country has been studying it, but now 48 years have passed, and we still have not succeeded in imitating it, so what is going on?Why can't we make it?
Let's take a look at what's next!
At that time, Vietnam presented us with the "Chinook" all-weather multi-functional heavy *** of the United States, which can not only transport supplies in wartime, but also transport soldiers, with a maximum speed of 315 kilometers per hour.
The United States "Chinook***."
Speaking of this ***, it served in the US military as early as 1963, but until now, the US military has still not retired this *** Of course, this *** has produced more than 1,000 aircraft, and with the development of time, it will also make some improvements on a regular basis, as for why the US military has not retired, or because the performance of this *** is still very good.
As the proud work of the U.S. military more than 60 years ago, "Chinook *** is not lagging behind now, it can weigh up to 2."The 7-ton load is transported up to 180 kilometers away, and if it is kept flying at an altitude of 1,200 meters, it can carry up to 22 tons when the weather conditions are suitable.
In addition to being able to perform combat missions, as a multi-functional ***, it can also perform tasks such as search and rescue, medical resources, disaster relief, and aircraft, so since it entered service, it has always been the "main equipment" of the US military, which is one of the reasons why it is still being produced and improved today, including in 2022, the US military has also purchased a batch of "Chinook*** again, which is enough to see how much the US military attaches importance to it.
To sum up, since its inception, "Chinook is the world's best transportation *** Its strong comprehensive performance is also the fundamental reason why it has not been eliminated."
Since the 60s of the last century, in many wars launched by the US military, you can see the figure of "Chinook", and my country in the 70s of the last century was given a "Chinook", we were also very happy at that time, thinking that if it can be imitated successfully, then it is naturally very beneficial for the development of China's transportation.
So why did China study 4years, but so far there has been no successful imitation
At that time, after our country received the "Chinook***", the top level of our army immediately arranged for people to study it, of course, if you want to study it, you need to disassemble it first, figure out its structure, and what the technology it uses.
However, although China's researchers have disassembled and assembled this *** many times, they still can't figure out its structure, as well as its key technologies, and even have a problem, until now, since the first dismantling of this transport aircraft, it has not been possible to completely assemble and restore it.
So later, my country confirmed that it was indeed impossible to imitate it, so it was stored in the aviation museum, which also made this hard-won *** unable to provide us with valuable information in the end.
In the 80s of the last century, with the game between the United States and the Soviet Union, the United States in order to win us over, after the ice of Sino-US relations was broken, it has been actively contacting our country, especially in the 80s of the last century, when there was a short period of "honeymoon period" between China and the United States, but it was still helpful for the development of our country.
At that time, when the relevant personnel of our country were invited to the United States for inspection, they proposed to purchase the American "Chinook transport aircraft", after all, we had been studying this *** gift from Vietnam for many years, but we still did not understand the key technology, so we planned to import it directly from the United States, maybe it can also help us to study.
However, because our country is not an ally of the United States, the United States did not agree to sell it to our "Chinook *** but the American Boeing Company, which was responsible for the production of "Chinook" *** at that time, found us in order to make money and said that it could be sold to our civilian version, in fact, this is also very helpful to us, but the "Sino-US honeymoon period" is too short, and we have not had time to reach cooperation with Boeing, just because Sino-US relations have cooled down again, so that we can't even get the civilian version.
Since the 90s of the last century, especially after the Gulf War, my country has seen how superior the performance of "Chinook ***, and this kind of multi-functional heavy transport *** is also a short board of our country, and it is a pain point that we urgently need to solve, so we have re-studied the "Chinook" *** presented by Vietnam, and found that it is still impossible to do.
So why is it that after more than 40 years, we still can't imitate "Chinook ***?".On the one hand, because the structure of this engine is different from the traditional one, it uses a very complex twin-rotor tandem structure, and its engine is also because the power level is too large, so that our past R & D personnel have no way to imitate it.
On the other hand, we have been studying this *** until the beginning of the 21st century, and then it was really because it was too difficult, so after deciding to give up the study of imitation, in 2007, China introduced the "MiG-26" large-scale transport from Russia and through the study of "MiG-26", so that we have made significant progress in large-scale design and manufacturing.
So now after more than 10 years of development, now we have the "straight 20" medium-sized general *** and the AHL heavy-duty *** is under development, if everything goes well, AHL heavy-duty *** will be completed before 2025, as a domestic heavy-duty *** It can catch up with us and the United States in the heavy-duty gap and reach the world's leading level.
It can be said that after so many years of development, although in many aspects, we have caught up with the gap between the past and the United States, but in many aspects, we still have shortcomings, such as the Air Force's strategic bombers, the Navy's nuclear aircraft carriers, nuclear submarines, etc., including the same in the field of heavy technology, of course, the gap is narrowing little by little, let's wait and see!
