Text Chapter 215: Armed Helicopter

Previous page        Return to Catalog        Next page

    Ever since the last time he went to the Red Army to urgently buy a sniper rifle and took a ride on a military helicopter at sea, Zhao Zeyong had a soft spot for this kind of thing.  In modern armed helicopters, they are tank killers and are indispensable.  But the Red Army was confident that he could get anything as long as he had money. When Zhao Zeyong came back to ask for goods from him this time, he said he was sorry.  The Red Army said that he really got a helicopter, and it was in active service with the army. However, when it was time to deliver the helicopter, he was warned by his elders and the matter was dropped.  Chinese helicopters can be exported, but this is not a trivial matter like rifles and rocket launchers. It involves political issues. Although Chinese helicopters are not advanced enough, they are not for everyone to buy and sell. Those who have a bad relationship with China are political.  Those who are sensitive will definitely not be sold. For example, people like Saddam and Gaddafi will definitely not be sold.  The reason why the Red Army is eyeing the military's helicopters is helpless. China does not currently produce many helicopters, and they are basically supplied to the military. The Red Army has been very careful and has not touched the most advanced aircraft. Unexpectedly  I chose an old airplane, but it was still discovered.  But Zhao Zeyong is really interested in helicopters.  Simply express your attitude, as long as one can fly into the sky, even an old aircraft from decades ago will do.  The Red Army really worked hard and found the man who searched all over the world.  A discontinued helicopter was almost pulled out of the museum, but it did meet Zhao Zeyong's requirements. This is a Z-5 helicopter.  ¡°It¡¯s still that the development of Chinese helicopters is too lagging behind, even further behind than fighter jets.  The world¡¯s first generation helicopter was developed in the 1940s.  All major countries in the world have developed first-generation helicopters, such as the American S-51, S-55/H-19, and Bell 47.  The Soviet Union's Mi-4 and Ka-18, the British Bristol-171, the Czech Republic's hc-2, etc.  The second generation was developed from the mid-1950s to the 1960s, including the American S-61, Bell 209/ah-1, Bell 204/uh-1, and the Soviet Union's Mi-6, Mi-8, and Mi-  24, France¡¯s sa321 Super Hornet, etc.  The third generation appeared in the 1970s and 1980s, including the American S-70/uh-60 Black Hawk, S-76, and AH-64 Apache, and the Soviet Union's Ka-50 and Mi-28.  France's sa365 dolphin, Italy's a129 mongoose, etc.  The fourth generation was developed after the 1990s, including the American rah-66 and s-92, and the international cooperation "Tiger", NH90 and eh101 models.  ??The development of China¡¯s first-generation helicopter only began in 1958. It was an imitation of the Soviet Mi-4 helicopter. It was not put into mass production until 1959, and a total of more than 500 helicopters were produced.  This is nearly a decade behind major countries.  At this time, others had already begun to develop second-generation helicopters.  "But the Z-5 is actually the helicopter that China has most closely followed the international pace, and it has seriously lagged behind in the subsequent helicopter development process.  The improved Z-6 of the Z-5 was only developed in 1966 and first flew in 1969. However, it was never put into production due to insufficient technology.  The Z-7 was developed in 1970 and stopped in 1979.  Straight 7 died halfway.  The Z-8 is an imitation of the Super Hornet helicopter imported from France. However, because the core components were never produced by ourselves, this aircraft had not been mass-produced by 2000 and was almost abandoned halfway.  ??Zhi 9 was developed and produced by introducing French technology patents, and it was finally successful.  However, as an active military equipment, it lags far behind other countries in the world.  Straight 10 after .  The Z-11 and other aircraft models are considered successful, but they have not yet entered mass production and fully equipped the army.  So only the Zhi 5 is reliable. Although the technology is backward, it has been equipped with the army in batches, and the quality is still reassuring.  Of course, the reason why China's helicopter technology lags so far behind does not mean that China's military technology is really that bad. It's just that helicopters have never been valued as much as fighter jets. Otherwise, a country that can build atomic bombs will not be as good as foreign countries.  There is a difference of more than three generations. A difference of one or two generations would be enough.  With this situation, Zhao Zeyong could only accept it and brought a Z-5 to the Republic of China. After it was dismantled, it was divided into parts and distributed to various secret research institutes for individual development.  I really feel wronged by the so-called secret research institute. The technicians here are quite proud of their identities and believe that they are engaged in the most secretive work. According to the Chinese consciousness, that should be the most important.  But in fact, many times they only work as draftsmen or engineers who restore drawings, and the technical content of their work is very low.  But Zhao Zeyong knew very well that the skills of the secret technicians he selected were actually not as good as those working in the factory research institute. Although the technicians in the factory felt that these secret scientific researchers were the best,  They can often come up with some fantastic ideas, but they don't know that Zhao Zeyong only got them. ????????????????????????????????????????????????????????????????????????????????????????? Zhi5 imitation work, Zhi5 is becoming less and less, but I¡¯m afraid there won¡¯t be any when I get home.Such an opportunity.  Old technology also has its benefits. This helicopter fuselage uses a steel tube frame, or simply pure wood, and the engine is a parallel-bar 7-star 14-cylinder engine, which is a bit difficult.  After all, the technicians of the federal province have not yet mastered the technology of multi-row engines. Multi-row engine technology was actually cutting-edge before World War II. Japan had never made a good engine. In World War II, their Zero aircraft did have enough horsepower, but  The oil leakage problem has never been solved.  The double-row engine on this straight 5 obviously does not have such a problem. After all, as a model that has been in service for more than ten years, there is no need to consider the issue of mature technology.  Now with the twin-row engine on the Z-5, it has suddenly opened the door for Dassault and other provincial aircraft designers. It turns out that many problems with the twin-row engine have been solved so simply, allowing them to start designing new high-horsepower engines with great interest.  .  Unexpectedly, bringing back an outdated helicopter would actually improve the design capabilities of fixed-wing aircraft. This really surprised Zhao Zeyong, but it was definitely worth it.  Since there was a prototype aircraft, and the technological gap between that of the federal province and that of the federal province was not too huge, it was not insurmountable. Therefore, technicians from the federal province quickly completed the design work of all components and handed them over to the aircraft manufacturer to manufacture each part.  Assemble the complete machine and start experimenting.  The result is very ideal. It is a mature and backward aircraft.  But there¡¯s a problem. There are no weapons on this aircraft.  Because it was given to a museum, the radar, weapons, etc. on it were all removed, and it was almost an antique that could fly.  So after completing the design of the helicopter at the aircraft factory, they began to design how to carry weapons.  Since the load capacity of the straight 5 is very limited, it can carry 1.2 tons of cargo and 1.35 tons when hoisted. It can transport two light jeeps.  But as for the weapons on it, what is appropriate to install? The technicians are divided into two groups. One group hopes to equip it with artillery, while the other group recommends equipping it with heavy machine guns or even rocket launchers. Installing cannons will have a great impact on the stability of flight, even for small-caliber artillery.  It is also not suitable for loading on helicopters.  In the end, a German technician who stayed in the United Provinces solved the problem.
