"If we look at it from a global perspective, Hummer off-road vehicles have a benchmark role." Nie Qianqian said to Qin Zhenhua.
Zhang Ming had already returned. Qin Zhenhua called Nie Qianqian over and asked her if she was familiar with these things. Sure enough, she did not disappoint Qin Zhenhua. Nie Qianqian directly told all the things she knew.
Tank and armored vehicles are studied, and this kind of Hummer off-road vehicle is different from civilians. It is also an armored vehicle! Even in the war in the desert oil area more than ten years ago, Hummer did not have it at that time.
How many armors, but after a series of combat experiences and lessons, the Americans have begun to add extra armor to the outer layer of Hummer. With only that layer of aluminum alloy armor, they cannot adapt to complex battlefield situations at all. It must
You must be able to block the common 7.62mm bullet shooting. Otherwise, on the battlefield, it is a living coffin, and a shuttle of bullets will be shot from any angle at any time to kill the people inside. Even if it can block 12.7mm
It would be even better if the machine gun bullets were used. In this way, additional additional armor would have to be hung outside, which is already considered as the category of military armored vehicles, and naturally it is within the scope of Nie Qianqian's research. In fact, Nie Qianqian has been studying these things
, So now, when Qin Zhenhua asks, he can answer questions smoothly.
Nie Qianqian continued: "From the performance of wars one after another, the Hummer has achieved the design goal. This car is highly mobility and flexible. It plays a versatile role on the battlefield and can adapt to various environments.
, So, if we want to develop such a vehicle in China, imitating it with Hummers as a prototype should be a good choice. Dongfeng Factory does not admit that it has imitated Hummers, which is just a kind of comfort. Of course, they are a few of them.
It's also a bit innovative, better than another aircraft factory, which copied all the designs of the full set of Hummers."
Now, all walks of life in China are developing in competition. It is very common for aircraft factories to build cars. However, Nie Qianqian also expressed his contempt for the practice of copying the whole thing. Dongfeng Factory can be said to be
Designed by themselves, because they did go through the entire design process, although there were also surveying and mapping, after all, they had a cycle of reincarnation, and another factory directly copied the entire set. Moreover, because they could not find a military Hummer, they directly copied a civilian Hummer.
The design is enough.
After hearing Nie Qianqian's words, Qin Zhenhua was a little surprised: "There is still competition in this project?"
Nie Qianqian nodded: "Of course, there will definitely be competition. Otherwise, if only one factory project participates, how can it be called bidding? There must be a few participating together. However, none of them can be fought. Dongfeng Factory
There should be no problem with this contract. Of course, if our factory has an idea, we can do it now. However, if we don’t have a qualified engine or gearbox, everything has to be repeated, and we probably can’t catch up in time.”
The first machine factory is engaged in heavy machinery, whether it is tanks or trucks, it is all heavy. In this 1.5-ton project, the first machine factory really does not have a suitable power system.
Dongfeng Factory is engaged in the China Railway Station, so they directly brought the Cummins engine they had, Dongfeng Cummins EQB150-20 four-cylinder supercharged intercooled diesel engine, 150 horsepower, and the original Detroit V8 engine
The same is true, it is 150 horsepower. Although there are some defects in maximum torque, it is not unacceptable. It is suitable to match it with a manual transmission. The engine of the first machine factory often has two or three hundred horsepower, for a 1.5-ton class
For four-wheel drive cars, it is a bit too big. If the engine is large and the power is too surplus, it is unnecessary, and it may even lead to higher fuel consumption.
Hummers are not only used for military purposes, but also for civilian purposes. After all, some people in the civilians also have this kind of demand, such as wealthy people, off-road enthusiasts, etc., and the aircraft factory directly copied a civilian Hummer. How can you
It may meet the needs of the army, so there is no big problem with Dongfeng Factory winning the bid, and Zhang Ming is also confident.
"How far has their car been developed at present?" Qin Zhenhua continued to ask Nie Qianqian. Nie Qianqian, the reporter, is really powerful, and there is nothing she doesn't know about. At this time, when she heard Qin Zhenhua's question, Nie Qianqian said: "
They are overcoming the difficulties of subsystems one by one. It is said that they have sent people to AM General in the United States due to frame problems."
"Are you going to ask for questions?" Qin Zhenhua was a little curious. It seemed that Dongfeng Factory was full of confidence, because they really worked hard. No wonder he said it was a surveying and mapping imitation. The other party was anxious and solemnly stated that it was self-developed.
Woolen cloth.
In fact, Qin Zhenhua doesn't care whether it is a surveying and mapping imitation or self-development. Whether it is a black cat and a white cat, as long as it can catch a mouse, it is a good cat. Whether it is a self-development or a surveying and mapping imitation, as long as it can meet the use of the army, it is a good one.
Equipment! One machine factory has done a lot of research and mapping and imitation. Anyway, there is no patent right in the military industry.
Hearing Qin Zhenhua's question, Nie Qianqian shook her head: "No...but, they didn't succeed in the end, because the interview of those few people failed, so they could only continue to work hard on their own research."
For a vehicle, if you want to have excellent performance, there are many factors. Take a frame as an example, there are many secrets inside. For ordinary cars, the frames are directly riveted with straight beams and longitudinal beams.
It is the simplest to get up. The beam of Mercedes-Benz heavy truck has variable cross-sections and is different from the front and rear. Although it is difficult to manufacture, it is good to use. The beam of Hummer is no exception, and it is even more complex. It is three-dimensional.
, How to make such a beam has become a difficult problem. Even if a car is placed in front of the designer and I don’t know how it was made, there is still nothing I can do about it.
An excellent frame can buffer the impact of the ground and balance the body. It is of great significance. At the same time, when moving in bumpy areas, the frame also needs strength and flexibility. These are all problems that engineers need to solve, so even if
Even if it is a surveying and mapping imitation, it is still of particular importance, not everyone can do it.
"Overall, this project of Dongfeng Factory is still full of expectations. If it can be successfully developed, it will be considered to fill the gap in the country." Nie Qianqian said.
