Coquettish Rebirth

"What's the matter? What do you think?" Jia Hongjian couldn't help asking, looking at Lao Hou's appearance. "I think Mr. Jia, you are talking about using lighting to make dot matrix numbers or characters... This thing should not be high-tech, right? At most, it is a program to trigger the launcher at a predetermined time. "Shooting"? This thing... If you want to do it, it may take seven or eight days?" Lao Hou said a little uncertainly.

In his mind, he felt that the difficulty of such a thing should not be high, isn't it just a programming trigger?How hard is this thing, huh?It's great, isn't it over if we use a single-chip microcomputer to control it?right?But, after all, time is too tight now, if there are still 15 days left, he dares to pat his chest and say that there is no problem!But it is because there are only 8 days, so I need to be a little conservative!What if it's not done in 8 days?Isn't it going to be his responsibility later on?

"Do you think it's okay for seven or eight days?" Jia Hongjian vaguely remembered what type of lighting fireworks were used in later generations. They seemed to be specially made things—it seemed to be in line with the idea of ​​being green and environmentally friendly in the National Games, so they specially used them. High technologies such as compressed air "cold launch" have been developed.I remember the principle of cold launch back then, and the reporter on TV said it was transformed from the director. It turns out that some of the directors of the Soviet system used cold launch directly, that is to say, directly used The compressed air first drives the guide a few meters or even higher outside the launch tube, and then ignites the guide at this time and then flies away.

So, when I heard about this thing at the time, it was to guide the technical army above to turn into civilians.Surely Jia Hung-chien decided it was high-tech!Besides, even if it's not high-tech.But it's compressed air, and it needs to be launched at a fixed height. The launching equipment and air pressure of these things must be very strict.So the first thing Jia Hongjian thought of just now was that even if this thing is easy to make, he might have to try it slowly for a month or two or even half a year.However, he is used to being foreign, and has never had the idea and habit of "indigenous steelmaking". Now after this old Hou reminded him.As soon as he heard that seven or eight days was enough, he immediately thought of indigenous steelmaking—what are the Chinese people best at?That is to use the most blood-spitting and simple method to make foreign high-tech!

For example, with such a cold launch technology, we don’t have any green national day sentiments now, so why can’t we use “hot launch” technology, right?Let's just use the more primitive launch method, and send it out with gunpowder at a glance.Can't you?right?Then the program-controlled stuff, we really don’t have high-tech, so let’s make a program-controlled system that doesn’t even need program control, just a machine-controlled control system that directly pulls the wire to pull the signal trigger, can’t it?

right?If you really want to think about this thing in a simple way, if you really want to make it in a relatively simple way.It seems that it is not difficult!You don’t even need to think about the quick reload and quick fire that Jia Hongjian said before—let’s put five or six flare guns side by side, and then fire the five or six flare guns in order from front to back. From a specific angle, these five or six signals can be photographed in a straight line up and down in the air, right?Although it is obvious from the side that it is "exposed", the problem is that the number or Chinese character that I typed out.It's only flat, and you can only see a row of signals going up from the side.I can't tell if it's a number or a Chinese character, okay?So you see, Jia Hongjian can come up with a very simple way to solve this problem just by slapping his head now!

If he can figure it out, then find a professional, such as a signal manufacturer in the army or something, wouldn't it be three times and five divisions?So at this time, Jia Hongjian also went for a walk, and he hurriedly asked Lao Hou to contact the people at the municipal party committee and government to see if anyone there knew who produced this kind of signal and launched it. 』The manufacturers of appliances and the like.As a result, Cheng Yu soon introduced one—a marine lifesaving equipment company called "Changxing" in Shanghai.

As for this Changxing company, it used to be a manufacturer under the establishment of the armed police. It originally took military lighting technology and used it to produce civilian marine life-saving lighting. In addition to a big rubber raft, there are various emergency food, drinking water, and of course lighting!As for this lighting, when there is a boat nearby, especially at night, it is useless for people on the life raft thousands of meters away to shout!So lighting is useful!

After getting in touch with this Changxing company, the Changxing company is quite caring!I just received a call from Huaxia Hi-Tech, and after confirming that it was indeed the call from Huaxia Hi-Tech, they learned about the general requirements on the phone, and then directly organized the backbone force to cross more than half of Shanghai in a car. Went to Huaxia Hi-Tech!For others, Huaxia Hi-Tech's list is a big list!Although the overall usage is not much, and although the time is tight, Huaxia Hi-Tech’s asking price is high——In the phone call, Jia Hongjian directly said that if this matter can be settled within a week, Huaxia Hi-Tech is willing to pay more than the purchase cost. 100 million RMB as a reward!Just for the 100 million yuan, the company really recruited the backbone of the signal, and even the senior engineers on the production line! [

After such a team came over, after hearing the detailed requirements of Huaxia Hi-Tech, they returned to their own company and started various researches. In their view, Huaxia Hi-Tech requires such precise control, and every signal After the sky, the distance must be constant, and precise positioning is required, which is really difficult!Ordinary signals do not have such a good positioning effect!If such precise control is really necessary, to be honest, not only the weight of each signal head must be very similar, but even the aerodynamic shape must be the same!This sounds like it should be done, but the problem is, this signal is not a child!Not for military use!For military use, it is required that the flying path must be stable or something, but this is a signal, this is not a lethal weapon, it is used to call for help!

You need to know about the signal, which is different from the structure of the general sub. The structure of the traditional signal is like this-in addition to launching the "drug", there is also a time fuze, which is "launched" out. After a second or so long, the time fuze ignites the propellant inside the signal, launches a small parachute out of the body, and ignites the magnesium and aluminum inside the body by the way powder, and then those powders give off a dazzling glow.In order to let the powder be blown away, there is actually a transparent frame structure around the powder to transmit light, and at the same time relying on the parachute above the head, the signal can stay in the air for as long as possible.

So, when the previous signal was actually manufactured, although the same standard parts were used, the requirements for the aerodynamic shape were not so strict, and the launch of the "drug" was not accurate enough. To that extent—to be honest, when calling for help at sea, what does it matter if the signal is emitted one meter higher or one meter shorter?But there is a big problem on Huaxia Hi-Tech's side!So it can be said that the current accuracy requirement problem is the biggest technical problem they have encountered since the establishment of the factory!

Faced with this kind of technical problem that has never been encountered before, the Changxing Company did not retreat. Instead, they actively studied how to solve this technical problem.First of all, they conducted a large number of tests, and they also cooperated with Laohou and the others to conduct the test - while understanding how high Laohou and the others required each signal to fly, and then continuously sending signals to To test how much propellant is needed to reach such a predetermined height.

At the same time, they also need to modify the body, removing the parachute inside the body, but in order to ensure that the test results will not be wasted, and do not change the weight and aerodynamics of the body, they are simply The parachute was removed, and then a similar counterweight was added, and then, at the same time, it was studied at the same time how to accurately launch rhythmic lighting at intervals within a few tenths of a second.

Looking at the pace of their research, to be honest, Jia Hongjian didn't know if he could finish it in 7 days, so he could only wait.Just in case the other party couldn't do it, Jia Hongjian and the others also made an alternative plan, which was to follow the plan designed by Lao Hou and the others before, which was to set off ordinary fireworks.

In this situation of not knowing what would happen, Jia Hongjian and the others gradually waited for 7 days.During these 7 days, although he was a little nervous, Jia Hongjian was still as if nothing had happened. He still took Celine Dion to try on costumes, change them, and adapt to the stage—in general Well, Celine Dion still gave Jia Hongjian a lot of face.According to René, his wife usually does not participate in the rehearsal when she participates in singing or something. At most, her assistant will come to participate, and then take pictures of the general rehearsal requirements and show it to her. How can she? What kind of rehearsal might I have traveled all the way to participate in?But now it's because of helping Jia Hongjian, so Celine Dion really didn't put on airs and went to the rehearsal in person!But that's okay, there are not as many rehearsals at Huaxia Hi-Tech as CCTV's various evening parties, and it's not to the point of torturing artists, so Celine Dion is also happy all day long, and she doesn't look disgusted at all.And at this time, Changxing Company came to a result on September 9th... The biggest motivation. Mobile phone users please go to m to read.)
