Chapter 1078: All Wins
"Really? Hahaha, then I was right in reporting the good news. Tell me, what is it?" The leader of the Ministry of Foreign Trade did not expect that just by saying it simply, there would actually be news.

Gao Zhendong knows how valuable the information here is. Comrade Zhendong never talks about unreliable things.

To be honest, when Gao Zhendong suggested this thing, he was thinking about fighting there, and he never thought that it could be used to transport cars to the sea: "Roll-on/roll-off ship! A type of ship specially used for centralized transportation of vehicles. This thing is naturally dual-purpose for military and civilian use. I once mentioned it to the navy, and they are also working on it, but I really don't know what state it is in now, and whether it can catch up with yours."

RoRo ship? Our language is very useful. It sounds like a ship that rolls on the ground to load cargo. Isn't this a car transport ship?

Although this type of ship was very new to the leader of the Ministry of Foreign Trade and he had never heard of it before, he could still roughly understand what Gao Zhendong said.

"There's such a thing? Great! I'll go ask them. Even if they haven't figured it out yet, it's good to have the idea. I'm confident that we will have more than 500 cars!"

After the leader of the Ministry of Foreign Trade finished his call with Gao Zhendong, he began to inquire with the Navy.

"Ah? How did you know we have this thing? It's not finished yet, but it will be soon, maybe next year, next year." The navy was very straightforward.

The design of this ship is not too difficult. Although our first 10,000-ton giant ship is still under construction and ships of this level cannot be built in large quantities, ships of several thousand tons can still be built.

This ship was originally designed for dual-use, and is usually used for civilian purposes. The navy also thought that if there was no place to use it, it could be placed on both sides of the Bohai Bay and used as a ferry, which would solve many problems. Unexpectedly, someone had already been eyeing it before the ship was even built.

"Haha, who else could it be? Whoever suggested you build this ship was the one who told me." The leader of the Ministry of Foreign Trade laughed happily on the phone. Hey, Comrade Gao Zhendong is so good. He not only prepared foreign trade commodities for us, but also prepared transportation tools. How embarrassing!

"Ah... him, no wonder, no wonder. He said early on that this is a dual-use ship. I didn't expect that he had already arranged the civilian use of the ship in advance. Military-civilian integration, military-civilian integration." The comrades in the navy were also very happy. This ship became a hot commodity before it was even built, which meant one thing.

——In addition to the use of ferries, there are enough civilian uses to support the daily operation of this type of ship, which is much more cost-effective than the navy's own maintenance of such ships! In addition to the first ship, the navy can even maintain a large-scale roll-on/roll-off fleet without spending a penny! This is a very useful strategic projection force.

Hehe... In this way, as long as we capture a dock, it means that armored cavalry will go ashore in large numbers, and then there is no need to say more about what will happen.

Comrade Zhendong is great. He not only proposed a good ship type, but also arranged how to use it and maintain the size of the fleet.

The two sides hit it off and both sides win!

Both the Ministry of Foreign Trade and the Navy felt that they had gotten an advantage and were very happy. At the same time, they were grateful to Gao Zhendong in their hearts.

All three parties won!

Gao Zhendong watched time pass by at work and didn't realize that he had won a huge prize, mainly because there were too many similar things happening.

He is at Beijing University of Technology, dealing with the problem of the people he released.

Sitting in front of him were Professor Liu and two comrades from the Technical Department of the Third Factory.

The reason they went to see Gao Zhendong was actually because of one thing: the training simulation system had encountered difficulties.

"... Chief Engineer Gao, under the guidance of Professor Liu, we have made some progress in solving other problems. The only problem is the shooting part of the training simulation system. We don't have a good solution..." reported a comrade from the Third Factory.

"I don't dare to be the instructor. It's the comrades you sent who helped me a lot! They are the experts in this area." Professor Liu smiled so hard that his teeth were showing. General Gao's soldiers are really powerful!
When comrades from the Third Factory go out, no matter how big or small they are, they are respectfully addressed as "expert comrade", which does not embarrass Gao Zhendong. This makes the progress of Professor Liu's project exceed expectations.

Of course, this is a brand new system, which may even be a bit premature, so there are still some problems.

Things that computers can simulate, such as trajectory, range, wind force, rate of fire, etc., can be solved through computers and electronic systems, but there is one problem that they are at a loss for - they cannot judge where the simulated firearms hit the simulation screen.

"Oh, this thing...tell me what you think about it?" Gao Zhendong smiled, even a little weirdly - his smile was filled with a little bit of nostalgia and innocence.

Seeing his smile, Professor Liu felt relieved. Judging from Commissioner Gao's attitude, he didn't seem to think there was anything difficult about this matter.

He guessed right. For Gao Zhendong, there really was a solution that was fast, efficient, economical, and not technically difficult. However, the source of this solution was a bit strange and had nothing to do with the system.

However, the comrades did not know Gao Zhendong's psychological activities, nor did they see the difference in his smile. Instead, the two comrades from the third factory were very excited. Chief Engineer Gao was testing and guiding us. Even if their previous thinking was meaningless, they believed that they could learn a lot with a big man like Chief Engineer Gao leading them in analysis.

"Boss Gao, at the beginning, we wanted to make a simulation device that could match the trajectory of a firearm to a certain extent and within a certain simulation distance, and then determine the shooting point by simulating the position of the projectile hitting the target area..."

The comrades from the Third Factory reported in a very organized manner, and their ideas were also everyone's initial intuitive reactions.

Gao Zhendong did not comment: "Well, then why didn't you adopt this method?"

The comrades from the Third Factory were a little embarrassed: "Professor Liu reminded us that the cost of making such a simulation device is no less than making a real one, and the difficulty is even higher..."

It is extremely difficult to make a simulated firearm with different propulsion principles and automatic principles, and some of its ballistics must be consistent with the real gun. It is like trying to make a gourd by copying a gourd, which is very troublesome.

It's better to just use a real gun.

"…and we also found that we don't have a good way to collect and judge the simulated bullet landing points at a low cost…"

For them, whether it is pressure or optics, circuit grid and other methods, it is difficult to achieve this, at least it is not cheap, and it will bring many limitations to the simulation equipment.

"Well, you are right. There is another problem. You cannot simulate the trajectory within 300 meters by controlling the simulated firearms or simulation systems, because these simulated projectiles are fundamentally uncontrollable."

This is the most troublesome part. Not to mention whether the projectile will land or not, the trajectory will not match the real thing. The simulation system is supposed to simulate the real battlefield in a small area. The inability to control the projectile at this time means that the trajectory cannot be simulated freely.

"Ah... there is still this problem. It seems that even if we solve the previous problems, this problem will be difficult to solve." The comrades from the Third Factory and Professor Liu finally understood the flaws of this method.

If it is possible to achieve the judgment of the impact point at any cost, then the full ballistic simulation is really impossible. The total simulation distance is so small, and the distance of the target can be achieved by mapping the perspective relationship to the target size. However, the flight, fall, wind deflection, etc. of the bullet, the physical projectile cannot be fully simulated.

It's impossible for comrades to train for indoor combat every day, right?
"Well, do you have any other ideas?" Gao Zhendong believed that his comrades had more than one idea, and they must have tried their best to think of everything they could think of before coming to him.

"Yes, yes, yes. Later we thought about using lasers, but there are two problems with lasers. First, large-area laser sensors are not cheap. Second, lasers are too directional and too fast, so it is difficult to simulate bullet trajectories."

Gao Zhendong laughed out loud, it's not good to have too good a personality, there's really no way to reason with this.

"Yeah, your consideration is correct. Laser simulation of ballistics is more troublesome and will bring a counterintuitive drawback. Add to that the cost of the sensor, and it's not so suitable."

"Yes, yes, Mr. Gao, we've been thinking about it over and over but can't come up with a good solution, so we have no choice but to come to you." The comrades from the Third Factory did not hide their helplessness and did not look at all inferior in front of Chief Engineer Gao.

Gao Zhendong said: "I have a solution for this. It's actually similar to your idea of ​​using a light gun, but it's just the other way around."

Reverse? This is new. The comrades thought about it for a long time but couldn't figure out how to reverse it.

"Haven't you figured it out?" Gao Zhendong's words were actually a little childish.

The three of them shook their heads in unison: "We haven't figured it out!" Even the two guys who were into electronics and computers couldn't figure it out, let alone Professor Liu who was into mechanics.

Gao Zhendong smiled and said, "It's actually very simple. You originally wanted to use the light gun to shoot light at the target on the screen or movie screen, right?"

"Yeah."

"Then why don't you do it the other way around? Instead of using a light gun, use a light receiver that looks like a gun. Use the target's light or image to hit the light receiver in reverse!"

At this point, Gao Zhendong burst into laughter. The reason he laughed was not because he was making fun of his comrades, but because he remembered the origin of this technology. That's why there was a bit of childishness in his expression.

——This is how the light gun shooting game on a certain Japanese game console works!
