Over the past few decades, the military industry of our country has experienced rapid developmentAll kinds of new military equipment have sprung up like mushrooms after a rainAmong them, there are some cutting-edge ** that have attracted the attention of the world.
In addition to the efforts of our scientific researchers, there is another reason why our country can achieve today's achievementsIn the 80s of the last century, China introduced a lot of advanced equipment and technology from abroad.
Many people have the impression that most of us imported technology and equipment from the former Soviet Union, Britain and other countries during that period, but in fact, our country did not lack it during this periodThe introduction of advanced military equipment from the erstwhile adversary, the United States.
Among them, what happened to the Black Hawk *** purchased by my country at that time? Why can't our country imitate it so far?
In the eighties of the last century, China's military aviation forces faced significant challenges, especially in the highland areas, where the supply of front-line posts was extremely difficultPeople carry horsesis not only inefficient, but also seasonally limited.
Once the road is closed by heavy snowfall, the sick officers and soldiers cannot receive timely medical treatment, and it is difficult to complete the border patrol mission.
At this time, China is in urgent need of an energyStable operation in highland areas***
In order to find the right one, our country conducts a rigorous bidding process. Three internationally renowned *** manufacturers – Sikorsky, Bell and France's European *** companies – participated in the bidding.
After a series of tests and comparisons,Sikorsky's Black Hawk*** stands out, this *** was relatively new at the timeWhen my country purchased it, the Black Hawk *** had only been in service for about 5 years.
Of course, whether it is the latest or not is not the key, the most important thing is to stillIt is necessary to match the needs of our country at that time.
This one***The maximum take-off weight is up to 9185 kgThe transfer range is more than 500 km, the external cargo hook is capable of lifting 3630 kg of cargo.
In addition, the excellence of this *** is not limited to transportation, also not to be underestimated in terms of operations.
It was based on this series of excellent abilities at that time, this Black Hawk *** of the United States is not only envied by other countries, but even the United States itself is using it in large quantities.
In 1984, China officially signed a contract with the United States to purchase 24 Black Hawks***, and the total value of the deal reached 1$500 million.And the Black Hawk purchased by our country is an improved typeCivilian version, equipped with a new engine, enhanced its high-altitude performance, butCannot be mounted without a mounter.
However, China bought it at that time for the purpose of operating in Tibetan areas, including such major tasks such as search and rescue, airlifting materials, and emergency rescue and disaster reliefSo there is no harm in the absence of combat performance.
With the arrival of these Black Hawks***,The squadron's logistical supply and medical support capabilities have been significantly improved.
Especially in the highland areas, the introduction of the Black Hawk *** greatly improved the living and working conditions of the army.
And at that time, in order to ensure that Chinese pilots were able to skillfully operate the "Black Hawk", Sikorsky cooperated with Chinese airlinesEight Chinese pilots were also trained.
However, over time, changes in U.S.-China relations have led to disruptions to Black Hawk components.
In response to this dilemma,China can only rely on dismantling the existing *** to get the required accessoriesto ensure the normal operation of the "Black Hawk".
Despite all the challenges, Black Hawk still plays an irreplaceable role in military applications in China's plateau region.
At the stage of test flights, the first "Black Hawk" was rapidFly to Korla, Xinjiang for adaptability testing.
Faced with the test brought by the high wind and sand area, the aircraft once suffered engine damage, but after the rapid repair of Sikorsky engineering and technical personnel, not only the fault was eliminatedHe has also accumulated experience in the maintenance of "Black Hawk" ** in desert environments.
In the months that followed, scientists conducted theoretical calculations, experiments, and test flightsSolved the problem of power drop caused by altitudes above 3000 meters.
In the course of service, the "Black Hawk"** participated in many important tasks, such as emergency rescue and disaster relief, search and rescue, material transportation, etc.
EspeciallyAir patrols during Hong Kong's handover in 1997, as well asIn 2008, Sichuan Wenchuan University ** Middle SchoolThe "Black Eagle" became the first aircraft to enter the disaster area to carry out rescue, providing much-needed assistance to the victims.
Nevertheless, it was not all smooth sailing for the "Black Hawk" during its service.
According to statistics, in the last almost 40 years,A total of 4 "Black Hawks" crashed, one of which occurred in 1988, when the pilot Qiu Guanghua flew the *** over the Doxiongla Pass, unfortunately crashed due to meteorological reasons.
Fortunately, all the crew survived, but unfortunately, Captain Qiu Guanghua later died heroically in the earthquake relief operation.
And according to 2021 data, more than 5,000 Black Hawks have been producedThe U.S. military alone accounts for nearly half of the world's totalIt also exports to more than 20 countries.
Although more than 30 years have passed since China came into contact with and used the "Black Hawk", it still has not succeeded in copying it.
Since the beginning of the last century, the American Black Hawk** has been renowned for its outstanding performance.
This is despite the fact that China bought a certain number of "Black Hawks" at the end of the last century**However, subsequent attempts at imitation were fraught with difficulties.
Among them, the complex structure of the "Black Hawk" ** and the highly confidential technical measures make the imitation work extremely difficult.
For example, its powertrain design is stunningly sophisticated, and it also has built-in mechanisms to prevent reverse engineering, so that some systems will destroy themselves if they disintegrate.
In addition,The composite technology used at that time was in the leading position and could not be replicated well.
Still, China did not give upInstead, they began to focus on independent research and development.
After years of hard work, China has finally succeeded in developing itStraight -20***The aircraft not only has the excellent performance of the "Black Hawk", but also has made major breakthroughs in key areas such as engines.
Among them, the turboshaft engine of the Z-20 adopts domestic advanced technology, which provides a strong driving force for it.
In addition, it is also equipped with an advanced rotor anti-icing system, which enables it to fly freely under complex meteorological conditions such as freezing rain and ice on the plateau, and has the ability to dispatch in all areas and at all times.The successful development of the Z-20 marks a significant improvement in China's mobile deployment capability in extremely high altitude areas of the plateau, especially in the border areas, which is of strategic significance.
The installation of the aircraft has further enhanced the delivery capability of the army unitsIt is equivalent to a division with the combat effectiveness of several divisions.
This change not only improves the combat efficiency of the army, but also provides it with a richer and more diverse choice of tasks.
Although the imitation plan of the "Black Hawk" ** failed to achieve its hopes,However, China has gradually narrowed the gap with the world's advanced level through independent innovationand even surpassed in some areas.
This journey is a testament to China's resilience in the face of challenges and its quest for technological independence.
And China's technological breakthrough is not limited to imitation. For the development process of the Z-20***, more honorable names need to be mentioned, such as:Deng Jinghui, chief designer of Z-20.
Deng Jinghui's team initially hoped to achieve a technological breakthrough through external cooperation, but was rejected by the other party.
In order to overcome this dilemma,It took them a full 20 years to sharpen their swordsFinally, in 2018, it met the technical conditions for the verification of rotor anti-icing in the extreme environment of the plateau.
At that moment,China became the fourth country after the United States, Russia and France to conquer this technology.
This milestone breakthrough is a testament to the technical strength and dedication of Tang and his team.
On the other hand, the development of the Z-20*** is crucial to the improvement of the mobility capabilities of the Chinese Army, especially in the vast but sparsely populated border areasThe efficiency of traditional land transportation is low, and military mobility has become a major problem.
And after equipping the Z-20,The squadron showed remarkable results in a wide range of maneuvers across the region.
